# TOC Text - numbers alignment

I am using \tableofcontents to create TOC in my document. however it is appearing as shown in the image. As the numbers increase the gap between the number and text is reducing.

You can use the tocloftpackage, e.g.

\documentclass{book}
\usepackage{tocloft}
\setlength{\cftchapnumwidth}{3em}
\begin{document}
\tableofcontents
\chapter{Lorem}
\setcounter{chapter}{9}
\chapter{Ipsum}
\setcounter{chapter}{99}
\chapter{Dolor}
\end{document}


The lengt \cftXnumwidth defines how wide the space for the number of X should be, where X is part (for \part), chap (for \ \chapter), sec (for \section) etc. See the tocloft manual for a complete list. Set this length to fit your needs.

• I get an error when including this package in an article: ! LaTeX Error: Command \c@lofdepth already defined. Or name \end... illegal, see p.192 of the manual. – CPBL Nov 18 '15 at 16:19
• When increasing cftchapnumwidth, one might want to also increase by the same amount cftsecindent and cftsubsecindent (in general, cftXindent for all lower levels), so that section numbers (etc.) keep starting below chapter titles as they do by default. tocloft doesn't document this, but the output looks odd (IMHO) otherwise. – Blaisorblade Jul 17 '17 at 4:10

You can use a package or simply redefine the section level command as follows:

\documentclass[11pt]{article}
\makeatletter
\def\l@section{\@dottedtocline{1}{1em}{2em}}
\makeatother
\usepackage{index}
\makeindex

\begin{document}
\tableofcontents

\section{One}
\section{Two}
\section{Three}
\end{document}


In the \def\l@section{\@dottedtocline{1}{1em}{2em}} change the 2em to suit. Here is the format of the \@dottedtocline{<level>}{<indent>}{<numwidth>}{<title>}{<page>}.

• I used your trick because tocloft completely remove all format of the toc. But with your command chapter in the toc are no longer written in bold. How can I fix this ? Maybe it is due to the fact that chapter is not a dotted toc line ? – Ger Sep 3 '12 at 10:14
• This was the only solution that worked for me, tocloft was causing many problems with hyperref and other errors impossible to decipher. I also implemented it correctly for sublevels, thanks! – Santi Aug 18 '16 at 8:54
• It works fine, but TOC is no longer bolded. – reducing activity Mar 9 '17 at 11:44

tocloft is a bit incompatible with KOMA-classes. The KOMA-bundle provides an own package tocstyle, that can be used with the standard classes as well. You can change the appearance of the toc, the right width will be iterated over several latex runs.

\documentclass{book}
\usepackage[tocindentauto]{tocstyle}
\usetocstyle{standard}
\begin{document}
\tableofcontents
\chapter{Duck}
\setcounter{chapter}{9}
\chapter{Penguin}
\setcounter{chapter}{99}
\chapter{Platypus}
\end{document}
