KOMA-script scrreprt: Chapter Heading Size Customisation

This is a continued question from my previous thread I am setting up LaTeX to write my thesis using scrreprt.

I have implemented with success all the advised and suggested solutions and have tried to tinker to achieve the final desired aesthetic change which was increasing the chapter name size.

Currently I am more than happy with the size of the chapter and chapter number, but I wasn't able to figure out the right way to control the chapter name. I used \addtokomafont{chapter}{\Huge} but could see no big change. I couldn't work out how to use a \scalebox. I also looked into using the \othersectionlevelsformat{sectioning name }{}{counter output } the KOMA-Script manual states on pg 97 that \renewcommand can be used to define formatting commands and that the original definitions in the KOMA-Script classes are:

\newcommand*{\partformat}{\partname~\thepart\autodot}
\newcommand*{\chapterformat}{%
\chapappifchapterprefix{\ }\thechapter\autodot\enskip}
\newcommand*{\othersectionlevelsformat}[3]{%
#3\autodot\enskip}


Please find below my current MWE, thank you in advance for any help.

\documentclass[
bibliography=totoc,
chapterprefix=true% like in standard class "report"
]{scrreprt}
\usepackage[left=2cm,right=2cm,top=2.5cm,bottom=3cm]{geometry}
\usepackage{xcolor}
\usepackage{graphicx}
\usepackage{minitoc}
\usepackage{setspace}

\setcounter{secnumdepth}{3} % number subsubsections
\setcounter{tocdepth}{3} % list subsubsections

\begin{document}
\dominitoc
\tableofcontents

\renewcommand*{\chapterformat}{%
\mbox{\scalebox{1.5}{\chapappifchapterprefix{\nobreakspace}}%
\scalebox{4}{\color{gray}\thechapter\autodot}\enskip}}

\setcounter{chapter}{6}\setcounter{page}{199}
\newpage\setcounter{page}{212}

\chapter{Conclusions}

Load the lmodern package so you can use very huge sizes, then use something like

\addtokomafont{chapter}{\fontsize{30}{38}\selectfont}


and this is the result:

• lmodern loads another font. I think fontenc is enough. Feb 11 '14 at 18:54
• Thank you for your reply it works, the font is not a big issue both are quite pleasing, much appreciated for the clear explanation. Have a nice day! Feb 11 '14 at 19:19
• @Marco If I load fontenc and not lmodern the font look quite different. Do you notice the same behavior or there is something strange in my distro? Feb 11 '14 at 19:34
• @MarcoDaniel It seems that the T1 options of fontenc breaks the \sffamily\bfseries used by KOMA classes. Can you confirm? Feb 11 '14 at 20:15
• @karlkoeller: I can confirm it too. Feb 12 '14 at 18:14
