[Tex/LaTex] Increasing spacing between section number and title in the table of contents

Question

I'm using the simple ordinary \tableofcontents command to produce a table of contents, and I find that the resulting spacing between the section number and the section title is too small:

Can someone tell me how to fix this, please. My documentclass is memoir, if that matters.

Answer 1

The width for the section numbers in the ToC is defined by the length called \cftKnumwidth, where K should be replaced by the sectioning level, i.e. chapter, section, etc. You can change it with \setlength, e.g.

\setlength\cftsectionnumwidth{4em}

See section 9.2.2 Typesetting the entries of the memoir manual for more on this.

A complete example:

\documentclass{memoir}
% \setlength\cftsectionnumwidth{4em} % uncomment to see difference
\begin{document}
\tableofcontents
\chapter{A chapter}
\setcounter{section}{999} % just for this example
\section{A section}
\end{document}
