LaTeX Paragraphs and New Lines: Blank Lines, \\, and \newline

To start a new paragraph in LaTeX, leave a blank line in your source file. To force a manual line break inside the same paragraph, use \\ or \newline. LaTeX handles normal line wrapping automatically, so most formatting problems on this topic come from confusing paragraphs with manual line breaks.

Key concept: LaTeX decides line breaks for you to create optimal text flow. You control paragraph breaks, and LaTeX handles the rest.

How LaTeX Handles Paragraphs

Creating Paragraphs

In LaTeX, a blank line creates a new paragraph:

Code
Rendered output

\documentclass{article}
\begin{document}

This is the first paragraph. It can span multiple lines in your source file, but LaTeX will format it as one continuous paragraph in the output.

This is the second paragraph. Notice the blank line above - that's what tells LaTeX to start a new paragraph. LaTeX automatically indents the first line.

\end{document}

Multiple Spaces and Line Breaks

LaTeX treats multiple spaces as one and ignores single line breaks:

Code
Rendered output

This    has    multiple    spaces.
This is on
multiple lines
in the source.

This is a new paragraph.

LaTeX ignores extra whitespace to give you flexibility in formatting your source code without affecting the output.

Manual Line Breaks

Using Double Backslash

Force a line break within a paragraph using \\:

Code
Rendered output

\documentclass{article}
\begin{document}

First line\\
Second line\\
Third line

This is still the same paragraph, but with forced line breaks.

This is a new paragraph.

\end{document}

Line Break with Extra Space

Add vertical space after a line break:

First line\\[10pt]
Second line with 10pt gap\\[0.5cm]
Third line with 0.5cm gap

Normal line break:\\
Next line

The \newline Command

Alternative to \\:

This is one line\newline
This is the next line

Preventing Line Breaks

Non-breaking Space

Use ~ to prevent line breaks between words:

% Prevent breaks in names
Dr.~Smith wrote Chapter~5.

% Keep units together  
The temperature is 25~°C.

% Prevent awkward breaks
See Figure~\ref{fig:example} on page~\pageref{fig:example}.

\mbox Command

Keep text together on one line:

The URL is \mbox{www.example.com/very-long-path}.

Paragraph Formatting

Paragraph Indentation

Control first-line indentation:

\documentclass{article}

% Remove indentation globally
\setlength{\parindent}{0pt}

% Or set custom indentation
% \setlength{\parindent}{1cm}

\begin{document}

This paragraph has no indentation because we set parindent to 0pt.

This paragraph also has no indentation. All paragraphs follow the global setting.

\indent This paragraph is manually indented using the indent command.

\noindent This paragraph has no indentation even if parindent is set.

\end{document}

Paragraph Spacing

Control space between paragraphs:

\documentclass{article}

% Add space between paragraphs
\setlength{\parskip}{1em}

% Remove indent when using parskip
\setlength{\parindent}{0pt}

\begin{document}

First paragraph with spacing after it.

Second paragraph with spacing before and after it.

Third paragraph.

\end{document}

Special Paragraph Commands

\par Command

Explicitly end a paragraph:

This is a paragraph.\par
This is another paragraph.

Centered Text

\begin{center}
This text is centered.\\
Multiple lines\\
can be centered.
\end{center}

% Or for short text:
{\centering This is also centered.\par}

Flush Left and Right

\begin{flushleft}
This text is\\
aligned to\\
the left.
\end{flushleft}

\begin{flushright}
This text is\\
aligned to\\
the right.
\end{flushright}

Advanced Line Breaking

Preventing Hyphenation

% Prevent hyphenation for specific words
\hyphenation{LaTeX JavaScript Python}

% Prevent hyphenation in a word
\mbox{unbreakableword}

% Allow hyphenation at specific points
super\-cali\-fragi\-listic

Line Breaking Commands

Command	Effect	Usage
`\\`	Line break	Most common
`\\*`	Line break (no page break)	Keeps lines together
`\newline`	Line break	Alternative to `\\`
`\linebreak`	Suggests line break	LaTeX decides
`\nolinebreak`	Prevents line break	Keeps on same line

Page Breaking

Control where pages break:

\newpage     % Start new page
\pagebreak   % Suggest page break
\nopagebreak % Prevent page break
\clearpage   % New page after floats

Common Patterns

Address Format

John Smith\\
123 Main Street\\
Anytown, ST 12345\\
USA

Poetry or Verses

\begin{verse}
Roses are red,\\
Violets are blue,\\
LaTeX is awesome,\\
And so are you!
\end{verse}

Quotations

\begin{quote}
This is a short quotation. It's indented from both margins and has no paragraph indentation.
\end{quote}

\begin{quotation}
This is a longer quotation that might span multiple paragraphs. The first line of each paragraph is indented.

This is the second paragraph of the quotation.
\end{quotation}

Best Practices

Paragraph and line break tips:

Let LaTeX decide - Don’t force line breaks unless necessary
Use blank lines - Clear paragraph separation in source
Be consistent - Choose either indentation or spacing
Use non-breaking spaces - Keep related items together
Avoid \\ at paragraph ends - Use blank lines instead

Common Mistakes

Avoid these errors:

Using \\ for paragraph breaks - Use blank lines
Multiple \\ in a row - Use \\[space] instead
Ending paragraphs with \\ - Creates underfull hbox warnings
Too many manual breaks - Trust LaTeX’s algorithm

Troubleshooting

Underfull/Overfull hbox

If you get these warnings:

Let LaTeX handle line breaking
Use \sloppy for problematic paragraphs
Rewrite sentences if needed

Unwanted Page Breaks

% Keep content together
\begin{samepage}
This content stays together on one page.
\end{samepage}

Inconsistent Spacing

Check these settings:

\setlength{\parindent}{15pt}  % First line indent
\setlength{\parskip}{0pt}     % Between paragraphs
\setlength{\baselineskip}{12pt} % Between lines

Quick Reference

What you want	How to do it	Example
New paragraph	Blank line	`text\n\ntext`
Line break	`\\`	`line\\line`
No indentation	`\noindent`	`\noindent Text`
Keep together	`~`	`Fig.~1`
Center text	`\begin{center}`	Centered
Extra space	`\\[1cm]`	With gap

Next: Learn about Bold, italics and underlining to add emphasis to your text.
