Line breaks and blank spaces

Breaking the document flow in LaTeX is not recommended unless you are creating a macro. Anyway, sometimes is necessary to have more control over the layout of the document; and for this reason in this article is explained how to insert line breaks, page breaks and arbitrary blank spaces.

Introduction

Line breaks are straightforward, a double backslash does the trick

\documentclass{article}
\usepackage[utf8]{inputenc}

\begin{document}
Something in this document. This paragraph contains no information 
and its purposes is to provide an example on how to insert white 
spaces and lines breaks.\\
When a line break is inserted, the text is not indented, there are 
a couple of extra commands do line breaks. 
\end{document}

This is not the only command to insert line breaks, in the next section two more will be presented.

Line breaks

As mentioned before, there's more than one way to insert line breaks.

\documentclass{article}
\usepackage[utf8]{inputenc}

\begin{document}
Something in this document. This paragraph contains no information 
and its purposes is to provide an example on how to insert white 
spaces and lines breaks.\\
When a line break is inserted, the text is not indented, there 
are a couple of extra commands do line breaks. \newline
This paragraph provides no information whatsoever. We are exploring 
line breaks. \hfill \break
And combining two commands
\end{document}

There are three commands here that work the same in the example:

• \\ (two backslashes)
• \newline
• \hfill \break

For more line-breaking commands see the reference guide.

Page breaks

There are two commands to insert page breaks, clearpage and newpage. Below is an example using clearpage.

\documentclass{article}
\usepackage[utf8]{inputenc}

\begin{document}
Something in this document. This paragraph contains no information and 
its purposes is to provide an example on how to insert white spaces 
and lines breaks.\\
When a line break is inserted, the text is not indented, there are a 
couple of extra commands do line breaks. \newline
This paragraph provides no information whatsoever. We are exploring 
line breaks. \hfill \break
And combining two commands

\begin{figure}
\centering
\includegraphics[width=4cm]{lion-logo}
\caption{Overleaf logo}
\end{figure}

Hello,  here  is  some  text  without  a  meaning...
\clearpage

If the command \clearpage is used, and there are stacked floating elements, such as tables or figures, they will be flushed out before starting the new page. In the example above the same image is inserted three times. Since the page break is inserted before all the figures are displayed, remaining images are inserted in an empty page before continuing with the text below the brake point.

If this is not what you need, you can use \newpage instead.

\documentclass{article}
\usepackage[utf8]{inputenc}

\begin{document}
Something in this document. This paragraph contains no information and 
its purposes is to provide an example on how to insert white spaces 
and lines breaks.\\
When a line break is inserted, the text is not indented, there are a 
couple of extra commands do line breaks. \newline
This paragraph provides no information whatsoever. We are exploring 
line breaks. \hfill \break
And combining two commands

\begin{figure}
\centering
\includegraphics[width=4cm]{lion-logo}
\caption{Overleaf logo}
\end{figure}

Hello,  here  is  some  text  without  a  meaning...
\newpage

In this case the images are placed in the new page trying to fit the text flow.

Horizontal blank spaces

Horizontal spaces of arbitrary length may be inserted with \hspace.

Horizontal \hspace{1cm} spaces can be inserted manually. Useful 
to control the fine-tuning in the layout of pictures.

Left Side \hfill Right Side

There are two commands that insert horizontal blank spaces in this example:

\hspace{1cm}

Inserts a horizontal space whose length is 1cm. Other LaTeX units can be used with this command.

\hfill

Inserts a blank space that will stretch accordingly to fill the space available.

The commands \hrulefill and \dotfill do the same as \hfill but instead of blank spaces they insert a horizontal ruler and a string of dots, respectively.

Vertical blank spaces

Vertical blank spaces have the same syntax as horizontal ones.

Text at the top of the page. Text at the top of the page. 
Text at the top of the page. Text at the top of the page. 
Text at the top of the page. Text at the top of the page. 
Text at the top of the page.

\vspace{5mm} %5mm vertical space

This text still at the top, 5mm below the first paragraph.

\vfill

Text at the bottom of the page.

Let's see the two commands that insert vertical blank spaces.

\vspace{5mm}

Inserts a vertical spaces whose length is 5mm. Other LaTeX units can be used with this command.

\vfill

Inserts a blank space that will stretch accordingly to fill the vertical space available. That's why the line "Text at the bottom of the page." is moved to the bottom, and the rest of the space is filled in.

There are other three commands commonly used to insert vertical blank spaces

\smallskip

Adds a 3pt space plus or minus 1pt depending on other factors (document type, available space, etc)

\medskip

Adds a 6pt space plus or minus 2pt depending on other factors (document type, available space, etc)

\bigskip

Adds a 12pt space plus or minus 4pt depending on other factors (document type, available space, etc)

Additional line-breaking commands

•  \\*
  

  (two backslashes and an asterisk)

breaks the line at the point of the command and additionally prohibits a page break after the forced line break.

•  \break
  

breaks the line without filling the current line. This will result in very bad formatting if you do not fill the line yourself. To fill the line, we can use it as given below.

•  \hfill\break
  

This will produce the same result as \newline and \\.

Additionally, LaTeX provides the following advanced option for line break.

•  \linebreak[number]
  

It breaks the line at the point of the command. The number provided as an argument represents the priority of the command in a range of 0 to 4. (0 means it will be easily ignored and 4 means do it anyway). When this line break option is used, LaTeX will try to produce the best line breaks possible.
