# Auto increase number width between minitoc chapter number and title

When the number of sections and subsections goes into the double digits the chapter number and title in the minitoc start to overlap:

\documentclass{book}

\usepackage{minitoc}

\setcounter{chapter}{9}
\begin{document}

\dominitoc% Initialization
\faketableofcontents

\chapter{bla}
\minitoc% Creating an actual minitoc

Any idea how to prevent this? Since I have a whole batch of documents like this it would be good to automate the width instead of applying a fixed width. Packages like tocstyle that offer settings like tocindentauto don't seem to affect mintoc.

• This is actually rather a \l@subsection or \l@section issue, in my point of view. – user31729 Apr 14 '16 at 18:49

As far as I can see, minitoc does not provide settings for horizontal settings, i.e. the numwidth under concern here. This is either set within commands such as \l@section and \l@subsection etc or use tocloft to add some spacing to the \cftsubsecnumwidth length register.

(I am unsure whether tocloft and minitoc are always compatible!)

The numwidth box is to small here and must be extended, the indentation has no effect on the width of this box -- it just shifts the box (to the right, usually)

\documentclass{book}

\usepackage{tocloft}

\usepackage{minitoc}

\setcounter{chapter}{9}
\begin{document}

\dominitoc% Initialization
\faketableofcontents

\chapter{bla}

• Thanks, is there anyway to auto indent rather than simply fixing the width to the widest known number of chapter numbers? – A Dark Divided Gem Apr 14 '16 at 18:56
• @ADarkDividedGem: This would require some testing of the width of the largest chapter number. \addtolength is normally a good way, better than \setlength{...} – user31729 Apr 14 '16 at 18:57
• And actually it's not the indent that causes the problem -- the numwidth is the problem. The indent just shifts the 'number' box to the right – user31729 Apr 14 '16 at 18:59
• Sorry wasn't familiar with the technical term but if no one can provide an automated way of increasing the number I will accept this as the answer and just pre-process the document counting the number of subsections to determine the width needed. – A Dark Divided Gem Apr 14 '16 at 19:23
• @ADarkDividedGem: It's possible, I think, but requires much more work. If you want to the total numbers of subsections you can apply xassoccnt (a package I've written), but it's more work to do – user31729 Apr 14 '16 at 19:25
