How To Add More Space In Latex Align
This commodity explores two methods of making changes to various aspects of paragraph spacing:
Readers interested in the fine details of line infinite calculations and paragraph structure:
The parskip parcel helps you lot safely change the space inserted between paragraphs in your document. It is designed to ensure that document structures such equally table of contents, list environments and display headings are not adversely affected by a not-nothing value of the \parskip command, which is used to fix the corporeality of space TeX/LaTeX inserts between paragraphs.
The parskip package doesn't provide any user-level commands; instead, it uses packet options to configure its actions. The parskip documentation is brief, simply three pages, but hither is a brusque summary of the package options:
By default, the parskip package sets \parindent to 0pt and provides a non-nix \parskip value of .5\baselineskip plus 2pt.
The following examples demonstrate some uses of the parskip packet. Select the "Open in Overleaf" links to open and compile the examples using Overleaf.
The following minimal case loads the parskip bundle and typesets two paragraphs created using the blindtext packet. The example besides typesets the default values of \baselineskip, \parskip and \parindent. The amount of space between the 2 paragraphs is determined by the value of \parskip:
\documentclass {article} % Cull a conveniently pocket-sized page size \usepackage [paperheight=16cm,paperwidth=14cm,textwidth=12cm] {geometry} % Load blindtext package for dummy text \usepackage {blindtext} % Load the parskip parcel without options \usepackage {parskip} \begin {document} \blindtext [one] \par %Use \par to force a new paragraph \blindtext [1] The value of \verb|\parindent| is \texttt { \the\parindent }. Here are the other values: \begin {itemize} \particular The value of \verb|\baselineskip| is \texttt { \the\baselineskip } \item The value of \verb|\parskip| is \texttt { \the\parskip } \end {itemize} \end {certificate}
Note that \parskip glue typically contains a stretchable glue component because that helps LaTeX fit content onto the folio and produce the best (optimal) page breaks.
The following example loads and configures the parskip package using the skip and indent options. It too typesets two paragraphs, via the blindtext package, and typesets the values of \baselineskip, \parskip and \parindent.
\documentclass {article} % Choose a conveniently small page size \usepackage [paperheight=18cm,paperwidth=14cm,textwidth=12cm] {geometry} % Load blindtext package for dummy text \usepackage {blindtext} % Load the parskip package with skip and indent options \usepackage [skip=10pt plus1pt, indent=40pt] {parskip} \begin {document} \blindtext [ane] \par % Apply \par to forcefulness a new paragraph \blindtext [1] The value of \verb|\parindent| was set via the \texttt {indent} selection, then it is now \texttt { \the\parindent }. The other values are: \begin {catalog} \item \verb|\baselineskip| is \texttt { \the\baselineskip } \item \verb|\parskip| was set via the \texttt {skip} selection, so its value is \texttt { \the\parskip } \cease {itemize} \stop {document}
The setspace package provides commands and environments to change the spacing of your document's lines of text. Here is a brief summary of the main commands and environments provided by setspace:
\begin {spacing}{2.5} ... ... \stop {spacing}

Using the singlespace* environment
Equally noted in the article Quick note on line spacing, the setspace parcel provides starred (singlespace*) and non-starred versions of the singlespace environment. Comments in the setspace packet code annotation that the singlespace* surround is designed to "... give improved vertical spacing around itemize and quote environments".
The following example uses itemized lists contained in ii minipage environments, placed side-by-side, to demonstrate the different spacing produced by the singlespace and singlespace* environments.
\doublespacing \blindtext [1] \begin {minipage}{.four\textwidth } \begin {singlespace} Here is a bulleted list\par (\texttt {singlespace} environment). \begin {catalog} \item One \detail Two \item Three \end {itemize} \stop {singlespace} % The list has ended. \end {minipage} \kern10pt% \begin {minipage}{.4\textwidth } \begin {singlespace*} Here is a bulleted list\par (\texttt {singlespace*} surround). \begin {itemize} \item One \item Two \detail 3 \end {catalog} \finish {singlespace*} The list has ended. \cease {minipage}

The following projection is compiled via LuaLaTeX and uses the fontspec parcel to access the TeX Gyre Pagella fonts. It compares two paragraphs of text typeset in TeX Gyre Pagella: the commencement paragraph uses the default single-line spacing and the second has a larger single-line spacing due to applying \SetSinglespace{ane.ane}. Some people may adopt the second, slightly "opened up", paragraph, finding it improves reading comfort, only that is, of course, a thing of personal preference.

In the adjacent department we review the commands \baselinestretch and \linespread.
Understanding \baselinestretch and \linespread
Part of LaTeX's blueprint for treatment line spacing and font changes (font size, font family, font encoding etc) makes employ of ii commands that y'all might see:
-
\baselinestretch: this control stores a scaling factor used to multiply (scale) the current value of\baselineskip. That scaling is typically applied the next time a font-selection command is used—such as\selectfont. To change the value stored by\baselinestretchyou should write\renewcommand{\baselinestretch}{calibration}- Note: If you write
\renewcommand{\baselinestretch}{calibration}in the body of the certificate, the new value of\baselinestretchwill not take firsthand effect: the newscalefactor is stored for future apply. To immediately use/employ the newcalibrationvalue, write\selectfontas demonstrated in the code fragment below.
- Note: If you write
-
\linespread{scale}: can be used to alter\baselineskipwithout affecting the electric current font size. This command sets\baselinestretchtocalibrationwhich later changes\baselineskiptoscale × \baselineskip. Withal, that scaling likewise does not take place immediately unless the\linespreadcommand is used in the certificate preamble. If\linespreadused in the certificate body, it takes effect after the next font sizing/selection command is used.
Based on the above, either:
-
\renewcommand{\baselinestretch}{scale}\selectfontor, -
\linespread{scale}\selectfont
could be used to change line spacing, and both volition piece of work across changes to the font size, as demonstrated in the case below. And then, which one should y'all use? Refer to this short word on tex.stackexchange.
Demonstrating \linespread
The following example uses \linespread{2.five} in the document preamble, which changes line spacing without requiring boosted font-option commands:
\documentclass {article} % Choose a conveniently small folio size \usepackage [paperheight=18cm,paperwidth=14cm,textwidth=12cm] {geometry} % Load blindtext package for dummy text \usepackage {blindtext} % Using \linespread in the preamble changes % line spacing without requiring additional % font-choice commands, such equally \selectfont \linespread {two.v} \begin {certificate} \blindtext [1] % The lines are afflicted by \linespread{2.5} \end {certificate}
Open this example in Overleaf
This example produces the following output:
Using \linespread{ii.5} in the document body (after \brainstorm{document}) would require font-selection commands to trigger the change in line spacing. Open the following code on Overleaf and compare the output with the previous instance:
Considering the following \verb|\linespread| command is used in the document trunk, a font-choice command is required to change the line spacing. Un-comment \verb|\selectfont| to see the difference: \linespread {2.5} %\selectfont % Without \selectfont the following paragraph lines are % unaffected afflicted by \linespread{2.5}: \blindtext [1]

Demonstrating \baselinestretch
The following example demonstrates \baselinestretch and \selectfont to show the corresponding effect(south) on \baselineskip:
The default value of \verb|\baselineskip|=\the\baselineskip. Now update \verb|\baselinestretch|\renewcommand\baselinestretch {2.5}. Notwithstanding, although nosotros take executed \vspace {5pt} \verb|\renewcommand\baselinestretch {2.5}| \vspace {5pt} \noindent it \textit {has not} (yet) had whatsoever effect: the new value of \verb|\baselinestretch| is stored, but not actioned. We can issue a \verb|\selectfont| command to make the change accept result; but, for now, the value of \verb|\baselineskip| is still \the\baselineskip {} (unchanged). If we now execute \verb|\selectfont| the change to \verb|\baselinestretch|, setting information technology to ii.5, will now accept outcome---\selectfont even though we are in the middle of a paragraph. Now, the value of \verb|\baselineskip| is \the\baselineskip {} (= \( ii . five \times 12 = thirty \mathrm {pt} \)). What happens if we alter the font size to 14pt and \verb|\baselineskip| to 16pt using the commands \verb|\fontsize {14}{16} \selectfont|? \fontsize {14}{sixteen} \selectfont Now, \verb|\baselineskip| is \textit {not} 16pt but \the\baselineskip {} because the value of \verb|\baselinestretch| (2.5) has been preserved and applied, giving \verb|\baselineskip| = \( two . 5 \times 16 = forty \mathrm {pt} \). \section { \texttt { \bfseries\string\linespread }} The \verb|\linespread| command tin be used to alter \verb|\baselineskip| without changing the font size.

This example produces the following output:
How is "line spacing" defined and changed in the setspace package?
The precise definition, and measurement of, "line spacing" is open to interpretation, which tin result in various implementations within software systems/applications. Clearly, the setspace packet has to assume a working definition of line spacing and then that it can provide back up for typesetting "unmarried-" and "double-spaced" lines, or any other multiple of line spacing. Only which variables are modified past setspace to produce lines with differing levels of white infinite between them?
Fortunately, discussions on tex.stackexchange and comments in the package code analyze how setspace implements lines spacing: it sets the value of \baselineskip using a multiple of the font's bespeak size.
Brief notes on fonts and bespeak size
Using fonts at a detail point size means applying a scaling factor to the character shapes (glyphs) in those fonts; once scaled co-ordinate to the betoken size, the visible size of the character is a function of the font's design (typeface). Point size has no universal, hard-and-fast, relationship to the bodily display size of character shapes within fonts.
The following epitome shows lowercase letters "abc" styled using 4 different fonts and all displayed at the same signal size. Annotation how the "size" of these lowercase letters varies according to the font's design (typeface) even though they are all typeset at the same point size:
Single line space in the setspace package
Nosotros can use discussions on tex.stackexchange equally a basis for some farther explanations.
A bones document using the article class has a default text font size of 10pt with a \baselineskip of 12pt. With the option [11pt] or [12pt] the article class uses a larger text size and correspondingly larger value for \baselineskip equally shown in the post-obit tabular array:
| option | font size | \(\texttt{\baselineskip}\) | \(\displaystyle\frac{\texttt{\baselineskip}}{\text{font size}}\) |
|---|---|---|---|
| [10pt] (default) | 10pt | 12pt | 1.2 |
| [11pt] | 10.95pt\({}^{\textbf{*}}\) | thirteen.6pt | ane.24 |
| [12pt] | 12pt | 14.5 | 1.21 |
\({}^{\textbf{*}}\)The reason for the anomalous value of 10.95pt, and not exactly 11pt, is nicely explained in this reddit mail service.
As shown in the tabular array, for each combination of text point size, and the corresponding default (i.e., single-line spacing) value of \baselineskip, the ratio
\[\frac{\texttt{\baselineskip}}{\text{font size}}\]
is close to 1.ii. That ratio value designates single-line spacing and provides the basis for line-spacing calculations used by the setspace package.
Agreement and computing values for \baselinestretch
To reach a particular line-spacing multiple such as ane.5, 2, 3 etc., the \baselinestretch command has to be set to seemingly "foreign" values; for instance by using the \linespread command. In this section we'll have a closer look at \baselinestretch to see how those "strange" values arise.
Permit's choose a certificate with default font size of \(f\) and default \baselineskip of \(\text{dbls}_1\), where the subscript \({}_1\) implies default \baselineskip value for single-line spacing at font size \(f\).
We'll ascertain unmarried-line spacing as the following ratio which nosotros'll refer to as \(\alpha_f\):
\[\frac{\text{dbls}_1}{f}=\alpha_f\]
For a given font size \(f\), let's also define the following line spacing values:
- a 1.5 multiple of line spacing is defined as
\[\frac{\text{dbls}_{1.5}}{f}=1.5\]
- a 2.0 multiple of line spacing is divers equally
\[\frac{\text{dbls}_{2.0}}{f}=two.0\]
- a multiple, \(m\), of line spacing is divers as
\[\frac{\text{dbls}_{m}}{f}=g\]
Using our single-line spacing, divers past the ratio \(\alpha_f\), we can write the post-obit "pseudo lawmaking" to piece of work out a \baselinestretch value corresponding to whatsoever line-space multiple \(yard\):
\[ \begin{marshal*} \texttt{multi spacing } (m) &= \text{a abiding } (\lambda) \times \texttt{single spacing}\\ \frac{\text{dbls}_{thousand}}{f}&=\lambda \times \alpha_f\\ 1000&=\lambda\alpha_f\\ \lambda&=\frac{k}{\alpha_f}\kern5pt(\text{refer to }\lambda\text{ equally }\texttt{\baselinestretch})\\ \implies \texttt{\baselinestretch}&=\frac{m}{\alpha_f} \finish{align*} \]
Let'south use 11pt text (really 10.95pt) and the default \baselineskip value of 13.6pt to summate \baselinestretch for double line spacing:
\[ \begin{align*} m&=two.0\\ \texttt{\baselinestretch}&=\frac{ii.0}{\alpha_f}\\ &=\frac{2.0}{\frac{\text{dbls}_1}{f}}\\ &=\frac{2.0}{\frac{xiii.vi}{11}}\\ &=2.0 \times \frac{xi}{13.six}\\ &=ane.618\\ \terminate{align*} \]
The following code fragment is used in the setspace package to achieve \doublespacing when the font size is 11pt. Note how the value of ane.618, equally calculated higher up, is stored in the command \baselinestretch:
\newcommand { \doublespacing }{ % \setstretch {1.667} % default \ifcase \@ptsize \relax % 10pt \setstretch {ane.667} % \or % 11pt \setstretch {one.618} % \or % 12pt \setstretch {1.655} % \fi }
Using an article document class with the 11pt font option, the following example compares \doublespacing with a spacing environment using our calculated value of 1.618 for \baselinestretch. Not surprisingly, the \baselineskip values are identical (22.00475pt):
\begingroup \doublespacing \verb|\baselineskip|=\texttt { \the\baselineskip } (via \verb|\doublespacing)| \blindtext [one] \endgroup \begin {spacing}{ane.618} \verb|\baselineskip|=\texttt { \the\baselineskip } (via \verb|\begin {spacing}{i.618})| \blindtext [i] \finish {spacing}
Open this case in Overleaf
This example produces the following output:
Similar calculations of \baselinestretch values apply to other font sizes and line spacing combinations, as listed in the post-obit tables:
Using TeX/LaTeX parameter commands
The post-obit sections explore a number of commands related to paragraph spacing/formatting: some of those commands are congenital into TeX typesetting engines, others are TeX/LaTeX macros. Commands built into TeX engines are known as primitives, meaning they are fundamental and irreducible because, dissimilar macros, primitives are not constructed from sequences of other commands.
In item, we'll consider a number of primitive parameter commands supported by all TeX engines, including pdfTeX, XeTeX and LuaTeX. Parameter commands, whether paragraph-related or not, are used to get the electric current value of the corresponding parameter, or set that parameter to a new value. For example, the \parskip control, a primitive, determines the value of a parameter which controls the amount of white space inserted betwixt two typeset paragraphs.
To get (here, to typeset) the electric current value of \parskip you would write:
To set up the current value of \parskip to 1pt plus2pt (a flexible glue) you could write something like this:
\setlength { \parskip }{1pt plus2pt}
Nosotros as well discuss some useful TeX/LaTeX macros, college-level commands written and constructed using a sequence of constituent commands.
Commands used for paragraph spacing
The following commands (primitives and macros) tin be used to affect paragraph spacing. Some are explored in more than particular which can be accessed past post-obit the link from the command proper noun.
Primitive commands
-
\parindent: the amount of indentation (white space) added to the start line of a paragraph. -
\parskip: the amount of flexible white infinite ("glue") placed between paragraphs. -
\rightskip: flexible spacing (glue) inserted to the right of each line in a paragraph. -
\leftskip: flexible spacing (glue) inserted to the left of each line in a paragraph. -
\baselineskip: the value of this parameter serves 2 roles:- it sets the desired altitude between the baselines of text in a paragraph;
- it is used to calculate the (variable) corporeality of space (glue) added betwixt lines in social club to attain the desired baseline-to-baseline distance (see later in the article).
-
\lineskiplimit: a parameter whose value defines the minimum acceptable distance between two adjacent lines of a paragraph. -
\lineskip: the corporeality of infinite (mucilage) inserted between two lines in a paragraph if the calculated\baselineskipgum would upshot in lines being too close together. -
\parfillskip: very flexible mucilage added at the end of the last line in a paragraph in society to "fill it" with white space; for a visual example, refer to the illustration in the section Visualizing other types of paragraph mucilage.
Macro commands
The following TeX/LaTeX macro commands are often used to modify paragraph spacing:
-
\offinterlineskipand\nointerlineskip: commands which can be used to switch off adding and insertion of\baselineskipglue; -
\baselinestretch: a command which stores a numeric factor used to summate the value of\baselineskipwhen a font is selected. It has a default value of i; -
\linespread: this command can be used to change the current value of\baselinestretch.
Flexible spacing (glue)
TeX engines achieve spacing furnishings, including within or between paragraphs, through the use of a flexible white space called glue which tin be stretched or shrunk co-ordinate to the amount of space required. If you want to larn about TeX's concept of glue, more details can exist found in the post-obit Overleaf manufactures:
- Exploring underfull or overfull boxes and badness calculations
- How TeX calculates gum settings in an \hbox
- Understanding underfull and overfull box warnings.
The fundamentals: parameter commands and examples
In this section we explain a number of paragraph-related parameter commands and provide examples of their use.
\parindent (TeX archaic)
This parameter command sets the amount of indentation (white space) added to the first line of a paragraph. It can be changed by using LaTeX's \setlength command; for case, to indent paragraphs past 15pt set \parindent to 15pt by writing:
\setlength { \parindent }{15pt}
Notation that:
- y'all tin can change
\parindentwithin a group, ensuring its effect is localized to paragraphs in that grouping; -
\parindenttin can be negative, producing an "outdent" rather than an indent; - by default LaTeX does not indent the first paragraph post-obit a document department heading (
\section{...}etc).
The following instance demonstrates the use of \parindent.
\documentclass {article} % Choose a conveniently small folio size \usepackage [paperheight=16cm,paperwidth=12cm,textwidth=8cm] {geometry} % Create a control to hold a paragraph of text \newcommand { \testpar }{ \texttt { \string\parindent=\the\parindent\ }When \TeX {} typesets a paragraph it treats each individual grapheme as a 2nd ``box'' with a specific width, height and depth.\par } \begin {certificate} % Set \parskip to put 10pt between paragraphs \setlength { \parskip }{10pt} % Prepare the value of \parindent to 0pt \setlength { \parindent }{0pt} \testpar % Set the value of \parindent to 10pt \setlength { \parindent }{10pt} \testpar % Ready \parindent in a group { \setlength { \parindent }{50pt} \testpar } % At present \parindent is over again 10pt \testpar % Yes, you tin can have a negative \parindent \setlength { \parindent }{-20pt} \testpar \terminate {document}
Open this example in Overleaf
This example produces the following output:
\parskip (TeX primitive)
The legibility of text can be enhanced by separating paragraphs with an corporeality of white infinite that will vary co-ordinate to some design aesthetic. TeX/LaTeX let users to command that inter-paragraph spacing via the \parskip parameter command.
- Advice from the
parskippackage: The parskip package advises that directly modifying\parskipcan "issue in vertical spaces in unexpected places" (inside a LaTeX certificate). Theparskipbundle attempts to set up spacing issues that might arise from changes to the value of\parskip—such as within table of contents and list environments. See likewise theparskippacket department of this article.
To manually set the current value of \parskip utilize LaTeX's \setlength command; for example, to divide paragraphs by 3pt you can write:
\setlength { \parskip }{3pt}
The following example demonstrates the use of \parskip:
\documentclass {article} % Choose a conveniently small page size \usepackage [paperheight=16cm,paperwidth=12cm,textwidth=8cm] {geometry} % Create a command to concord a paragraph of text \newcommand { \testpar }{ \noindent The electric current value of \texttt { \string\parskip } is \texttt { \the\parskip }. When \TeX {} typesets a paragraph it treats each individual character every bit a 2D~``box'' with a specific width, superlative and depth.\par } \begin {document} \testpar % Gear up \parskip to 5pt \setlength { \parskip }{5pt} \testpar % Set parskip to 10pt \setlength { \parskip }{10pt} \testpar % Set \parskip to 25pt (just in a group) { \setlength { \parskip }{25pt} \testpar } % Grouping ends, now \parskip is once more 10pt \testpar % Yeah, you tin can have a negative \parskip \setlength { \parskip }{-20pt} \testpar \cease {certificate}
Open this example in Overleaf
This instance produces the following output:
Flexible \parskip
Traditionally, \parskip is not a fixed value, which would event in the same amount of space between all paragraphs. Instead, \parskip is usually defined as a "flexible infinite" (chosen glue) which enables TeX to stretch or shrink the space between paragraphs, helping to fit content on the page and find a "good" identify for a page pause.
To brand \parskip flexible you would write it in the grade of a glue specification:
\setlength{\parskip}{fixed corporeality plus amount to stretch minus amount to shrink}
where plus and minus are keywords used by TeX/LaTeX to identify the amount to stretch or amount to shrink contained in a glue specification. The Overleaf commodity Exploring underfull or overfull boxes and badness calculations contains a more in-depth discussion of glue.
For instance, to enable \parskip to vary between three + i = 4pt and 3 — ane = 2pt you could write
\setlength { \parskip }{3pt plus1pt minus1pt}
\leftskip and \rightskip (TeX primitives)
TeX engines provide ii parameter commands which add space (glue) to the left and right of each line in the typeset paragraph. As their names suggest:
-
\leftskipinserts infinite (mucilage) to the left of each line in a paragraph; -
\rightskipinserts space (glue) to right left of each line in a paragraph.
The following examples use \leftskip and \rightskip to directly change paragraph alignment; notwithstanding... changes to text alignment are usually all-time achieved via suitable LaTeX environments or packages—for example, meet the Overleaf article on text alignment. Although we demonstrate the behaviour of some low-level (primitive) parameter commands provided past TeX engines, it is generally appropriate to use advisable LaTeX packages wherever possible.
Making \leftskip stock-still and \rightskip flexible
The following example produces two paragraphs: the first uses LaTeX'southward default values for \leftskip and \rightskip and the 2d paragraph is typeset using the following settings:
\leftskip 10pt \rightskip 0pt plus one make full
Open up the following Overleaf project to run into the output:
\documentclass {article} \title {Second leftskip and rightskip example} % Choose a conveniently small page size \usepackage [paperheight=16cm,paperwidth=12cm,textwidth=8cm] {geometry} % Prepare the value of some paragraph-related parameters \setlength { \lineskip }{iii.5pt} \setlength { \lineskiplimit }{2pt} \setlength { \parindent }{20pt} \setlength { \baselineskip }{12pt} \begin {document} \input text.tex % A generated TeX file which defines the macros % \mytextA and \mytextB, each containing the text for a paragraph. % Typeset a paragraph with default values of \leftskip and \rightskip \mytextB % Fix \leftskip and \rightskip to new values \leftskip 10pt \rightskip 0pt plus 1fill \vspace {8pt} % Now re-typeset the same paragraph \mytextB \terminate {certificate}
Open up this example as an Overleaf LaTeX project
This case generates the following output:
The post-obit graphic is an annotated version of the second paragraph produced by the example above. Information technology is designed to highlight and show the corporeality of \leftskip and \rightskip glues inserted in the paragraph lines, together with the \parindent infinite for the first line:
Notation that \leftskip glue has a stock-still size (10pt) but \rightskip glue has stretched to provide any corporeality of white space required to fill the correct-hand side of each line. This "flexibility" is due to the specification of \rightskip which contains plus one fill—providing an "infinitely stretchable" course of glue.
Making \rightskip fixed and \leftskip flexible
The following example produces two paragraphs: the first uses LaTeX's default values for \leftskip and \rightskip and the second paragraph is typeset using the following settings:
\leftskip 0pt plus 1 fill up \rightskip 10pt
Open the following Overleaf projection to encounter the output:

This "flexibility" is due to the specification of \leftskip which contains plus 1 fill—providing an "infinitely stretchable" form of glue.
Setting \leftskip and \rightskip to flexible values
The following example produces two paragraphs: the first uses LaTeX'south default values for \leftskip and \rightskip and the second uses the following, flexible, glue settings:
\leftskip 0pt plus 1fill \rightskip 0pt plus 1fill
These settings result in paragraph lines existence centered:
\documentclass {article} \title {leftskip and rightskip examples} % Cull a conveniently small-scale folio size \usepackage [paperheight=16cm,paperwidth=12cm,textwidth=8cm] {geometry} % Set the value of some paragraph-related parameters \setlength { \lineskip }{3.5pt} \setlength { \lineskiplimit }{2pt} \setlength { \parindent }{20pt} \setlength { \baselineskip }{12pt} \begin {document} \input text.tex % A generated TeX file which defines the macros % \mytextA and \mytextB which define text for two paragraphs % Typeset a paragraph with default values of \leftskip and \rightskip \mytextB % Set \leftskip and \rightskip to "extremely flexible" gum settings \leftskip 0pt plus 1fill \rightskip 0pt plus 1fill \vspace {20pt} % Now re-typeset the same paragraph \mytextB \end {document}
Open this example equally an Overleaf LaTeX project
This example generates the post-obit output:
The following graphic is an annotated version of the second paragraph produced by example in a higher place. Information technology is designed to highlight and show the amount of \leftskip and \rightskip glues inserted in the paragraph lines, together with the \parindent space for the commencement line:
Note that both \leftskip and \rightskip are specified as 0pt plus 1fill making them equally "infinitely flexible"; consequently, they stretch by the same amount which results in typeset lines being centred.
Setting \leftskip and \rightskip in a group
The following case shows how to make temporary changes to \leftskip and \rightskip by enclosing them inside a group. In our case the group is created past \begingroup... \endgroup, as shown in the following code fragment:
\begingroup \leftskip 0pt plus 1fill \rightskip 0pt plus 1fill \mytextB \endgroup
The first paragraph is typeset using "extremely flexible" mucilage for \leftskip and \rightskip:
\leftskip 0pt plus 1fill \rightskip 0pt plus 1fill
only the 2d paragraph uses LaTeX's default values:
\documentclass {article} \title {Another leftskip and rightskip example} % Cull a conveniently pocket-sized page size \usepackage [paperheight=16cm,paperwidth=12cm,textwidth=8cm] {geometry} % Set the value of some paragraph-related parameters \setlength { \lineskip }{3.5pt} \setlength { \lineskiplimit }{2pt} \setlength { \parindent }{20pt} \setlength { \baselineskip }{12pt} \brainstorm {document} \input text.tex % A generated TeX file which defines the macros % \mytextA and \mytextB which define text for two paragraphs % Here nosotros change \leftskip and \rightskip to "extremely flexible" glue settings % within a group created past \begingroup ... \endgroup \begingroup \leftskip 0pt plus 1fill \rightskip 0pt plus 1fill \mytextB \endgroup % Now re-typeset the same paragraph after the group has closed % causing \leftskip and \rightskip revert to their previous values \vspace {20pt} \mytextB \terminate {certificate}
Open this example every bit an Overleaf LaTeX project
This example generates the following output:
Note: The settings for (effects of) \leftskip and \rightskip are restricted to the paragraph within the group created past \begingroup... \endgroup. Subsequently the group has been closed, the next paragraph is typeset using LaTeX's default values for \leftskip and \rightskip.
\baselineskip (TeX primitive)
It is generally accepted typesetting practise that lines of text within paragraphs should be equally spaced, except where certain lines incorporate big elements, such as mathematics or an image, which make it impossible to preserve abiding interline spacing for such lines.
TeX/LaTeX provide commands and mechanisms which enable users to exercise some degree of control over interline spacing. One such command is \baselineskip which gets, or sets, the value of a parameter that determines the preferred interline spacing (baseline-to-baseline altitude) in a typeset paragraph.
To typeset the current value of \baselineskip you can write
To fix \baselineskip to some value (a LaTeX length such every bit pt) you tin can write
\setlength { \baselineskip }{value}
For instance, to ready \baselineskip to 12pt you can write
\setlength { \baselineskip }{12pt}
We can demonstrate the role of \baselineskip by using the following (typical) paragraph:
and adding annotations which show the baseline-to-baseline distance controlled by \baselineskip:
The diagram also shows the interline "glue": a calculated corporeality of white space added between lines—nosotros'll further hash out this later in the commodity.
\baselineskip and other parameters
\baselineskip is i of four core parameters which control the amount of infinite inserted between lines of a paragraph; the others are:
-
\lineskip -
\lineskiplimit -
\prevdepth
Subsequently in the commodity we'll explore how these 4 parameters are used to calculate interline mucilage values.
\baselineskip example (stock-still space)
The post-obit example opens in Overleaf to create a project containing a file called text.tex which defines the commands \mytextA and \mytextB—both commands typeset a paragraph. For convenience, the Overleaf project uses a minor folio size because that assists with preparing graphics and images for this help page.
\documentclass {article} \championship {Demonstrating baselineskip} % Choose a conveniently minor page size \usepackage [paperheight=16cm,paperwidth=12cm,textwidth=8cm] {geometry} % Prepare the value of some paragraph-related parameters (we will discuss these) \setlength { \lineskip }{3.5pt} \setlength { \lineskiplimit }{2pt} \setlength { \parindent }{20pt} % Set the value of \baselineskip---change the value to encounter the effect \setlength { \baselineskip }{12pt} \begin {document} \input text.tex % A generated TeX file which defines the macros % \mytextA and \mytextB, each of which typeset a paragraphs % Firstly, typeset two paragraphs with the default \baselineskip \mytextA\mytextB % At present alter \baselineskip to a larger value and typeset % another paragraph \setlength { \baselineskip }{24pt} \mytextA \finish {certificate}

This example generates the post-obit output:
The paragraph on page 2 has widely spaced lines considering \baselineskip was set to 24pt.
\baselineskip example (flexible infinite)
The following example specifies a \baselineskip value which has an extremely flexible (so-called "infinite") stretch component:
\baselineskip=12pt plus1fil Considering of this flexibility, white infinite between paragraph lines can stretch past any amount required to fill the folio. Such flexibility would result in paragraphs having very different amounts of space between their elective lines of text, which might not be aesthetically pleasing or easy to read.

A few notes on glue
Some of the following notes are taken from the Overleaf commodity exploring underfull or overfull boxes and badness calculations, reproduced here for convenience.
The white space that TeX inserts between lines of a paragraph, \baselineskip, is a form of flexible spacing called glue. A gum value can be specified three components:
- a stock-still amount;
- an amount it can stretch;
- an amount it tin can shrink,
Consequently, a \baselineskip value can be specified like this:
\baselineskip=fixed amount plus amount to stretch minus corporeality to shrink
where
- plus and minus are keywords that TeX engines sympathize;
- fixed amount is referred to as the normal component of the glue (as well called the natural width of the gum);
- amount to stretch is referred to as the stretch component of the glue;
- amount to shrink is referred to as the shrink component of the mucilage.
The fixed amount is required for all gum values simply corporeality to stretch and amount to compress are both optional—if either, or both, are missing they are fix to a value of 0.
Usually, \baselineskip gum is specified with a stock-still amount but, the stretch and compress components are zippo, otherwise paragraph lines would have irregular (variable) spacing, which might not exist aesthetically pleasing.
\offinterlineskip and \nointerlineskip (macros)
These macros are often used to prevent insertion of interline glue betwixt lines of a paragraph. Readers interested in more detail can bound ahead to the relevant article sections which explain how these macros work.
-
\offinterlineskip: See the article section Zero-sized interline gum: \offinterlineskip. -
\nointerlineskip: See the article section Preventing interline glue: \prevdepth and \nointerlineskip.
Paragraph structure and line space calculations
Using the capabilities of LuaTeX it is possible to mail-procedure a typeset paragraph to visualize boundaries of constituent characters (glyphs), lines and glues from which information technology is constructed. We'll start with a brusque sequence of graphics to assist visualize the "boxes and gum" model that TeX engines apply to typeset text independent in a paragraph.
Paragraph structure
When TeX typesets a paragraph it treats individual characters equally miniature boxes, each with its own width, height and depth and those character-box widths are used to calculate the optimum locations for linebreaks. In improver, infinite characters contained inside the text, and used to separate individual words, are converted to a form of flexible space (glue) which provides the spacing needed to accomplish each linebreak.
The following sequence of 7 graphics evidence the core components of a typeset paragraph: various types of boxes and glue. The first graphic shows a typeset paragraph together with an annotated version which highlights diverse elements within the paragraph. Nevertheless, the annotated paragraph contains a lot of data so the subsequent graphics isolate various components to (hopefully) brand them easier to understand.
- The adjacent graphic depicts paragraph lines equally gray boxes separated past glue that is represented by horizontal green strips. That glue is calculated to ensure the baseline-to-baseline distance is equal to (i.east., the value of)
\baselineskip:
- The side by side image represents typeset characters every bit boxes: to visualize how TeX engines procedure characters for the purpose of producing linebreaks:
- The next image shows boxes within boxes: the larger paragraph lines (boxes) containing smaller boxes (individual characters):
- The next image shows the amount of space between words in each line: these inter-word spaces are produced by converting space characters to flexible glues that are stretched or shrunk to produce the correct length for each line of text. Annotation carefully that the size of these spaces vary from line-to line:
- The next paradigm combines the character boxes and corresponding glues (space) placed between individual words:
Visualizing other types of paragraph glue
The following paragraphs were also typeset and candy using LuaTeX to evidence other types of glue inside, and between, a pair of paragraphs. Note that \rightskip and \leftskip are both set to 0pt, and so they are non shown:
-
\parskipgum (lite blue) placed between the ii typeset paragraphs; - individual words are separated by interword gum (xanthous) created by converting space characters in the input to variable-sized white space (glue) in the typeset output. Glue arising from interword spaces is stretched or shrunk to achieve visually pleasing linebreaks;
-
\baselineskipgum (low-cal greenish) placed betwixt lines—the exact amount of\baselineskipglue is calculated using the mechanism discussed below; -
\lineskipmucilage (red) being used in the second paragraph—due to the low box contained in the second-to-last line; -
\parfillskipglue (dark green) placed at the end of the concluding line in each paragraph.
Dealing with deeper (or taller) lines (boxes)
Every bit shown by graphics in the previous section, a typeset paragraph is a vertical stack of "boxes", separated by some white space, which TeX calls "glue". Equally the paragraph is processed, and the individual lines (boxes) are stacked, the vertical list (stack) grows in a downward direction, toward the bottom of the page. Although TeX/LaTeX try to ensure paragraph lines are stacked with baselines separated by a constant distance of \baselineskip, it's not e'er possible to achieve that because certain lines can have a larger-than-usual height or depth.
The height and depth of each paragraph line is determined by the maximum distance that line'due south content extends in a higher place or below the baseline; consequently, paragraphs containing cloth with a relatively large elevation or depth, such as inline math or graphics, are likely to produce individual lines with correspondingly large heights and/or depths. For such lines, TeX/LaTeX may be unable to stack them such that their baselines are separated from other lines by the \baselineskip amount. Clearly, TeX/LaTeX need a "fallback mechanism" to handle such lines by calculating a suitable amount of infinite to insert between each pair of lines affected past large heights and/or depths.
\lineskip and \lineskiplimit (TeX primitives)
That fallback machinery involves the parameter commands \lineskip and \lineskiplimit together with a tertiary parameter chosen \prevdepth. Readers interested in further details tin can leap ahead to the article section How the infinite (glue) betwixt paragraph lines is calculated.
The case projection, below, typesets a unmarried paragraph whose final line has a relatively big depth due a shifted text box (\hbox). The paragraph is typeset using these settings:
\setlength { \baselineskip }{12pt} \setlength { \lineskip }{3.5pt} \setlength { \lineskiplimit }{2pt} \setlength { \parindent }{20pt}
Utilize the link below the following lawmaking to open an Overleaf project:
\documentclass {commodity} % Use a conveniently small page size \usepackage [paperheight=16cm,paperwidth=12cm,textwidth=8cm] {geometry} % Set some of import parameters \setlength { \baselineskip }{12pt} \setlength { \lineskip }{3.5pt} \setlength { \lineskiplimit }{2pt} \setlength { \parindent }{20pt} % Input file defining \testpar \input testpar.tex \title {A sample paragraph for lineskip} \begin {document} \testpar % A macro created in the Overleaf project \end {document}
Open up this case in Overleaf.
This example produces the post-obit output:
The following graphic uses an annotated version of the paragraph produced by the previous Overleaf project. Here, we zoom in to focus on the terminal paragraph line, indicating the utilise of \lineskip glue (shown in scarlet) caused past the depth of the shifted text box:
The final line of the paragraph text has a larger-than-usual depth, preventing TeX from maintaining the constant baseline-to-baseline distance specified past the value \baselineskip (12pt). As indicated by arrows on the right-hand side of the graphic, TeX/LaTeX effort to ensure a fixed altitude (12pt) between pairs of lines—the value of \baselineskip. However, for the terminal pair of lines TeX has separated them by an corporeality greater than 12pt and uses the value of \lineskip for the interline glue instead of a value calculated using \baselineskip.
The following sections explore and explain the details of TeX's calculations of interline glue values.
How the space (gum) betwixt paragraph lines is calculated
For electric current purposes we'll very briefly mention TeX's page-construction process, admitting in a highly simplified way! Once TeX has finished typesetting a paragraph, by completing hyphenation and determining linebreaks, you tin can think of that paragraph data equally existence stored in a temporary retentivity location. TeX and then needs to motility that paragraph data, line-by-line, to a new retention location which stores material destined for the current output page.
When TeX moves the paragraph data, line-by-line, it is, in upshot, building a vertical stack of lines (TeX boxes) which grows downward toward the bottom of the page. As it moves paragraph lines to the electric current folio TeX tries to ensure those lines will be spaced equally, having consistent vertical (baseline-to-baseline) spacing equal to the value \baselineskip. When a new line is transferred to the current page, the TeX engine temporarily records that line'due south depth considering it will be used to calculate the amount of interline gum (white space) between that line and the line placed after it.
Mucilage size calculations
Let's start past summarizing the interline spacing features provided by TeX engines:
- keeping a constant distance betwixt baselines, a distance equal to
\baselineskip; - provide spacing for whatever lines with a relatively large height or depth;
- a capability to switch off insertion of interline mucilage—either automatically or under user control. For example:
- TeX engines automatically disable insertion of interline mucilage after a rule in vertical fashion;
- the macros
\offinterlineskipand\nointerlineskipallow users to temporarily switch off insertion of interline glue—those macros take different furnishings, as nosotros'll come across below.
The decision whether to add interline glue and, if so, how much of which type, goes like this:
- Should interline glue be added? TeX decides this past testing whether the depth of the last line added to the list is less than the special value of
–1000pt(points). Notation that–1000ptis an arbitrary "lookout man" value used internally past TeX engines.- Note: The value of "depth of the last line added", which TeX records internally, is also known as the "previous depth". TeX engines provide the parameter command
\prevdepth—which can, in sure circumstances, exist used to get or set up the value of "previous depth". The macro\nointerlineskipmakes utilize of\prevdepth.
- Note: The value of "depth of the last line added", which TeX records internally, is also known as the "previous depth". TeX engines provide the parameter command
- TeX tests whether
depth of previous line is greater than –1000pt?- Yes it is (need to add glue):
- summate the value Δ, where Δ = \baselineskip – (depth of previous line) – (top of adjacent line)
- compare Δ to the value of
\lineskiplimit, a parameter used to define the minimum acceptable distance betwixt two lines, equally measured by the distance between the bottom of the upper line and the top of the lower line. - If Δ <
\lineskiplimit:- the lines are also shut so insert the minimum adequate spacing which is
\lineskip
- the lines are also shut so insert the minimum adequate spacing which is
- If Δ >=
\lineskiplimit:- the lines are not too close so use Δ equally the corporeality of glue to insert
- No information technology is not (practice non add glue):
- Add the next line (box) without inserting whatever glue
- Yes it is (need to add glue):
The post-obit graphic summarizes the interline glue procedure:
An example of interline glue calculations
In the following example we assume that TeX/LaTeX is using the post-obit control parameter values:
\baselineskip=12pt \lineskip=3.5pt \lineskiplimit=2pt
We'll look at the interline glue calculation for the first two lines of this paragraph:
In the next image, the TeX engine has processed the offset paragraph line and moved information technology to the vertical list it is edifice. It keeps track of that line's depth (d1 ) which is 2.1528 (points):
Next, TeX is ready to add a second line to the list it is building: that line has a height (h2 ) which is 6.9444 (points) and, incidentally, a depth, d2 of 0 (points):
At this signal, TeX needs to calculate the corporeality of space (glue, g1 ) to insert between these two lines:
The post-obit paradigm shows the glue calculations for this pair of lines:
The concluding image shows the two lines moved beyond to the current page with the calculated amount of interline glue placed betwixt them:
All the same some other parameter: \prevdepth
Every bit noted higher up, when TeX is creating a vertical stack (list) of boxes, it stores the depth of the concluding box added to that listing. That stored depth value is known as the "previous depth" which can be accessed via the parameter command \prevdepth.
The \prevdepth command can be used only when TeX is in a vertical mode; i.e., between paragraphs or inside vertical boxes: \vbox, \vtop or \vcenter (annotation: \vcenter boxes can only exist used in math mode).
\prevdepth provides read and write access to the value of "previous depth":
- to read admission the current value of
\prevdepthyou can write:
- to ready the current value of
\prevdepthtosome value, a length in points, mm, etc, you tin can write:
\setlength { \prevdepth }{some value}
If you attempt to apply \verb\prevdepth in circumstances it was not designed for, such every bit inside a paragraph or inside an \hbox you lot'll get an error
with additional information telling you it can merely exist used in vertical mode.
Preventing interline gum: \prevdepth and \nointerlineskip
One utilize of \prevdepth is to forbid TeX performing the baseline calculations used to add interline glue betwixt items in a vertical listing, such as the lines of a paragraph. Using \prevdepth to represent depth of previous line we tin re-state the mucilage calculations (pictured above) equally follows:
if(\prevdepth > –1000pt) { Δ = \baselineskip — \prevdepth — (peak of current line) if(Δ < \lineskiplimit) interline glue = \lineskip else interline glue = Δ } else { Stack the box without adding whatsoever interline mucilage }
Internally, TeX engines recognize a so-chosen "sentry" value of \prevdepth which can exist used to disable calculating and adding interline gum. That sentinel value is –1000pt, which tin exist seen in the first line of the pseudo-code above:
TeX volition not add interline gum unless \prevdepth is greater than –1000pt— which provides the mechanism used past the \nointerlineskip macro to foreclose baseline gum being added between the side by side pair of boxes in a vertical list.
\nointerlineskip has a definition equivalent to:
\def\nointerlineskip { \prevdepth–1000pt }
Note that \nointerlineskip provides a one-off deactivation of interline glue calculations considering the value of \prevdepth is continually updated as new boxes are added to the electric current vertical list, as demonstrated in the following example:
\noindent The post-obit \verb|\hbox|es are processed when \TeX {} is in so-called \textit {outer vertical mode}. Later processing (typesetting), these boxes are appended to the current page and stacked vertically with interline glue inserted betwixt them: \hbox {j} \hbox {p} \hbox {g} Now, immediately later after the box \verb|\hbox {j}|, we set up \verb|\prevdepth| to \texttt {-1000pt} which prevents interline glue being placed between the boxes \verb|\hbox {j}| and \verb|\hbox {p}|: \hbox {j} \setlength { \prevdepth }{-1000pt} \hbox {p} \hbox {g} Observe that interline gum \textit {is} placed betwixt the boxes \verb|\hbox {p}| and \verb|\hbox {grand}| because the value of \verb|\prevdepth| is updated after \verb|\hbox {p}| is processed and added to the list: the value of \verb|\prevdepth| becomes the depth of the box \verb|\hbox {p}|. When \verb|\hbox {grand}| is added to the vertical list the value of \verb|\prevdepth| is no longer \texttt {-1000pt}; consequently, interline glue can now be added.
Open this instance in Overleaf
This example produces the post-obit output:
Zero-sized interline glue: \offinterlineskip
It is possible to remove all interline spacing via the macro command \nointerlineskip, which has a definition equivalent to:
\def\offinterlineskip { % \baselineskip=-1000pt \lineskip=0pt \lineskiplimit=\maxdimen }
Note that \maxdimen is 16383.99998pt, the largest length that TeX tin can use.
The post-obit graphic shows the cadre interline glue calculations and the various parameter values used by the macro \nointerlineskip:
The following graphic shows the pseudo-lawmaking fragment which results from substituting the \nointerlineskip macro values into the glue calculations. It demonstrates how the \nointerlineskip macro works by setting values for \baselineskip and \lineskiplimit such that the interline mucilage will always exist \lineskip glue of 0pt.
\offinterlineskip and not-cypher \lineskip
The \nointerlineskip macro sets \lineskip to naught but, as the post-obit Overleaf project demonstrates, yous tin combine \nointerlineskip with non-nothing values of \lineskip to achieve line spacing furnishings.
\documentclass {commodity} \title {Demonstrating not-zero lineskip} % Cull a conveniently pocket-sized page size \usepackage [paperheight=16cm,paperwidth=12cm,textwidth=8cm] {geometry} \brainstorm {document} \offinterlineskip % This sets \lineskip to 0pt \setlength { \lineskip }{5pt} % We desire non-cypher \lineskip \input text.tex % A generated TeX file which defines the macros % \mytextA and \mytextB, each of which typesets a paragraph \mytextA % Typeset a paragraph % Now change \lineskip to a flexible glue value and typeset % another paragraph \setlength { \lineskip }{5pt plus5pt minus5pt} \mytextA \end {document}
Open this case as an Overleaf LaTeX project
This example generates the following output:
You can localize the effect(s) of using \offinterlineskip and \lineskip (and other spacing commands) by enclosing them in a group:
\begingroup \offinterlineskip \setlength { \lineskip }{5pt} ...your paragraph(southward) here \endgroup
