Proportional To (∝) symbol in LaTeX

The proportional to symbol is used as a relational operator, In order to print this symbol in LaTeX, you can use the default command \propto. Also, there are a lot more packages that provide commands to print this symbol with a slightly different style.

So in this tutorial, I will show you all of those packages and commands to get your preferred style of this symbol.

Proportional To symbol in all styles

The given table will help you to get your preferred style of Proportional To symbol.

Package	Command	Output
None	\propto
stix	\propto
mathabx	\propto
MnSymbol	\propto
fdsymbol	\propto
amssymb	\varpropto

let’s see some examples with the default command.

\documentclass{article}
\begin{document}

  $$ \verb|\propto| \rightarrow \propto $$
  $$ m \propto n $$
  $$ F \propto a $$
  $$ P \propto V $$

\end{document}

Output:

let’s see some examples with the stix package.

\documentclass{article}
\usepackage{stix}
\begin{document}

  $$ \verb|\propto| \rightarrow \propto $$
  $$ m \propto n $$
  $$ F \propto a $$
  $$ P \propto V $$

\end{document}

Output:

Approximately Proportional To symbol

To get the Approximately Proportional To symbol in LaTeX, you have to put a tilde (~) symbol under a Proportional To (∝) symbol. You can do that with \underset, \overset, or \stackrel command. For better understanding let’s see some examples.

\documentclass{article}
\usepackage{amsmath}
\begin{document}

$$ \verb|\underset{\sim}{\propto}| \rightarrow \underset{\sim}{\propto}$$
$$ \verb|\overset{\propto}{\sim}| \rightarrow \overset{\propto}{\sim} $$
$$ \verb|\stackrel{\propto}{\sim}| \rightarrow \stackrel{\propto}{\sim} $$

\end{document}

Output:
