# How to use only serif fonts in whole document?

Cheers,

I'm wondering how to use only serif fonts in whole document. Remark: I use one of the koma-script document classes, which employ sans-serif fonts for chapter and sectioning headers.

I've managed to change the tableofcontents with koma, but e.g. setkoma commands won't work for all the headings.

Thank you a lot in advance!

This is my main document:

\input{chapter/header}
\setlength{\unitlength}{1mm}
\makeindex
\makenomenclature

\begin{document}%

\begin{spacing}{1}%Normal Spacing
\renewcommand*{\theHchapter}{0.\arabic{chapter}} %so that no double Chapter I (prob with hyperref)
\pagenumbering{roman}
\setcounter{secnumdepth}{-1} %No number in front of Chapter
\maketitle

\clearpage
\thispagestyle{empty}
\hfill
\clearpage

\input{chapter/Declaration}

\clearpage
\thispagestyle{empty}
\hfill
\clearpage

\input{chapter/Abstract}

\clearpage
\thispagestyle{empty}
\hfill
\clearpage

\renewcommand*{\theHchapter}{\arabic{chapter}} %so that no double Chapter I (prob with hyperref)
%TOC etc.
\setcounter{secnumdepth}{4} %Numbers in front of Chapter etc
\setcounter{tocdepth}{4}
\pagenumbering{Roman}

• Welcome to TeX.SX! Please help us help you and add a minimal working example (MWE) that illustrates your problem. Reproducing the problem and finding out what the issue is will be much easier when we see compilable code, starting with \documentclass{...} and ending with \end{document}. – Stefan Pinnow Mar 7 '18 at 14:56
• \renewcommand\sfdefault{\rmdefault} ? – David Carlisle Mar 7 '18 at 14:59
• Are you looking for the document class option egregdoesnotlikesansseriftitles? – user36296 Mar 7 '18 at 15:01
• I can't compile your mwe. – Tarass Mar 7 '18 at 15:04
• Please don't remove your code. You might consider editing it to make it more minimal, but deleting it now you've got an answer is just destructive. – cfr Mar 8 '18 at 4:28

To make all the headings "no sans serif" - or for short "serif" - there is a special documentclass option:

\documentclass[egregdoesnotlikesansseriftitles]{scrbook}

\begin{document}
\chapter{test}
test
\end{document}

• @StevenB.Segletes you have to be really annoying to make a package author add such an option:-) – David Carlisle Mar 7 '18 at 15:04
• I suspect that the option "egregdoesnotlikesansseriftitles" was, until now, the most obscure and/or least-documented of all options of the koma-script document classes. No more! :-) – Mico Mar 7 '18 at 15:14
• @mldmnn Another way to picture it is this, your profile, tex.stackexchange.com/users/156599/mldmnn, shows your presence on this site has reached a total of 28 people, at this moment. Compare it to tex.stackexchange.com/users/4427/egreg, which shows that, at the moment, egreg has reached a total of 33.7 million people by his presence here. One may not always agree with egreg's preferences, but one should never foolishly ignore his advice. Gravitas!!! – Steven B. Segletes Mar 7 '18 at 15:40
• @StevenB.Segletes The food chain theory makes total sense! It also explains why David Carlisle has the second most rep, because egregdoesnotlikepinapplepizza, thus he is safe from the food chain – user36296 Mar 7 '18 at 17:32
• Best option name ever! – egreg Mar 7 '18 at 18:40
