# How to increase spacing for a fraction

so I have the following:

\usepackage{amsmath}
\usepackage{amsfonts}
\setlength{\parindent}{0pt}
\newcommand{\forceindent}{\leavevmode{\parindent=3em\indent}
\begin{document}
\forceindent $f(\chi_i)=\frac{1}{|G|}\sum_{b\in G} {f}(b)\chi_i(b)$\\
\end{document}


However I want to increase the space of the horizontal line and |G| as it looks too involved

\documentclass{article}

\usepackage{amsmath}
\usepackage{amsfonts}

\begin{document}

$f(\chi_i)=\frac{1}{|G|}\sum_{b\in G} {f}(b)\chi_i(b)$

$f(\chi_i)=\frac{1}{\rule{0pt}{0.75em} |G|}\sum_{b\in G} {f}(b)\chi_i(b)$

\end{document}


(if too much, reduce 0.75em)

• thank you, 0.65 is what I was looking for – Maths Nov 14 '18 at 10:21
