When I type $\varprojlim_n$ in the common inline math environment I get the picture as below.

However I want to be rendered as enter image description here.

The same thing happens with summations. I understand that if I use the paragraph math mode it will solve my problem. Unfortunately, that is not an option. Is there any way to do this?

There are four styles used in typesetting math formulas which affect the size and certain formatting parameters (notably the placement of sub and superscripts on variable size symbols):

  • \textstyle: default in the running text and in array environment
  • \displaystyle: default for displayed equations
  • \scriptstyle:: default for first-level sub and superscripts
  • \scriptscriptstyle: default for higher-level sub and superscripts

Take a look at the following document to see how the appearance changes when different styles are used:

\documentclass{article}

\usepackage{amsmath}


\begin{document}

$\textstyle\sum_{i=1}^\infty x_i$,
$\displaystyle\sum_{i=1}^\infty x_i$,
$\scriptstyle\sum_{i=1}^\infty x_i$,
$\scriptscriptstyle\sum_{i=1}^\infty x_i$

\end{document}

enter image description here


Now, coming back to your specific query, use \displaystyle.

\documentclass{article}

\usepackage{amsmath}


\begin{document}

$\varprojlim_n$ $\displaystyle\varprojlim_n$

\end{document}

    or 999 times out of 100, it is better to use display math than inline math with \displaystyle so use \[\varprojlim_n\] – David Carlisle Aug 25 '17 at 8:23
