Poorly spaced TOC from Lyx (chapter numbers and title merge)

Question

Context: I am using Lyx with the KOMA-Script-Book class to generate a book with a table of contents. I am not using any special hacks, just the vanilla configuration via the Lyx GUI. My preamble has only one line of code \setcounter{chapter}{-1}.

Problem: The contents page shows the chapter numbers too close to the chapter titles. See image below to best illustrate the problem.

Any suggestions for how to fix?

The numbers in a TOC are placed in a box of a set width (so the text following the number aligns). You need to increase this setting. Though I have no idea as to how one does that in LyX. — daleif, Dec 13 '22 at 14:36
try \KOMAoptions{toc=flat}. Or read the KOMA documentation about more options to adapt the table of contents. — Ulrike Fischer, Dec 13 '22 at 17:07
thanks @UlrikeFischer that worked. if you'd like to make it an answer I'll mark it as done. (I added toc=flat as an option in the lyx UI) — Penelope, Dec 13 '22 at 21:02
It's highly unlikely that Lyx has anything to do with this. The spacing of chapter and section numbers is almost always defined by the document class. See How to modify the space between the numbers and text of sectioning titles in the table of contents? — barbara beeton, Dec 13 '22 at 21:28
Thanks @barbarabeeton - I was surprised as by default I'd expect tex / latex to layout such that it wasn't squished, especially as there is enough space available. — Penelope, Dec 13 '22 at 22:41

I have no idea about Lyx (what is it?) but for the traditional classes (book, report, article) the tocloft package lets you do what you want.

\usepackage{tocloft}
\addtolength{\cftchapnumwidth}{2em} % increase space for chapter numbers

thanks Peter - useful reply. I found the solution by Ulrike was simpler for Lyx. Lyx is a GUI for editing documents typeset by latex which aims to be zero-code (but clearly keeps failing. https://en.wikipedia.org/wiki/LyX – Penelope Dec 13 '22 at 21:03
as Penelope uses the KOMA classes, tocloft is probably not the best solution. – Ulrike Fischer Dec 13 '22 at 21:12
