# How to indent everything but titles?

While passing parskip=half to scrbook removes all indentation, I (unfortunately) should indent everything by 10 mm, excluding chapter/section/... titles. How can this be achieved easiest? I was considering toying around with bcor and putting section numbers into the (fake) margin, but that seems pretty complicated...

edit It's a bit late to add this, but ideally the titles' texts (not the numbering) would also start at that indentation and be aligned, i.e.

+----------¦-----------+------¦---------------+
|    1     A chapter   |    3 Another chapter |
|    1.1   A section   |      some text       |
|    1.1.1 A subsection|  3.1 another section |
...


That should be answered in this question though.

• You should “outdent” titles, instead. – egreg Nov 30 '15 at 13:03
• @egreg How? And will this work correctly for a twoside layout? – Tobias Kienzler Nov 30 '15 at 13:05
• What do you mean? What should happen to titles in left-hand and right-hand pages? – egreg Nov 30 '15 at 13:08
• @egreg "outdenting" titles would mean I should increase the margin, right? But in a twoside layout and using \usepackage[inner=10mm, outer=20mm]{geometry} how could I increase only the "left" margin no matter whether the page is odd or even? Would bcor work here? – Tobias Kienzler Nov 30 '15 at 13:16
• I think you just want 2cm on either side, with titles sticking in the margin (inner on odd pages, outer on even pages) by 1cm. – egreg Nov 30 '15 at 13:22

Second Update: If the chapter and section titles etc. should be aligned to the indented text you can use:

\documentclass[
paper=a4,
%chapterprefix
]{scrbook}[2015/10/03]

\newcommand\secnumwidth{1.5cm}

\makeatletter
\renewcommand\chapterlinesformat[3]{%
\IfArgIsEmpty{#2}
{#3}
{\@hangfrom{\hspace{-\secnumwidth}\makebox[\secnumwidth][l]{#2}}{#3}}%
}

\renewcommand\sectionlinesformat[4]{%
\IfArgIsEmpty{#3}
{#4}
{\@hangfrom{\hspace{-\secnumwidth}\makebox[\secnumwidth][l]{#3}}{#4}}%
}
\makeatother

\usepackage[
layoutsize={\dimexpr\paperwidth-\secnumwidth\relax,\paperheight},
layoutoffset={\secnumwidth,0cm},
inner=1cm,
outer=2cm,
showframe,
]{geometry}

\usepackage{blindtext}% dummy text

\begin{document}
\tableofcontents
\chapter{Kapitel}
\blindtext
\section{Abschnitt}
\subsection{Unterabschnitt}
\subsubsection{Unterunterabschnitt}
\blindtext
\blindtext
\end{document}


Result:

Update: It is better to use only the geometry options like @egreg showed in his answer. But the following code works also if the KOMA-Script option chapterprefix is used.

\documentclass[
paper=a4,
chapterprefix
]{scrbook}[2015/10/03]

\RedeclareSectionCommands[indent=-10mm]{section,subsection,subsubsection}

\renewcommand*{\chapterformat}{%
\hspace{-10mm}\mbox{\chapappifchapterprefix{\nobreakspace}\thechapter
\autodot\IfUsePrefixLine{}{\enskip}}%
}

\renewcommand{\chapterlineswithprefixformat}[3]{%
#2\hspace{-10mm}\parbox[t]{\dimexpr\textwidth+10mm}{\raggedchapter#3}%
}

\usepackage[
layoutsize={20cm,27.9cm},% cut 1cm from the width
layoutoffset={1cm,0cm},% put it in the offset
inner=1cm,
outer=2cm,
showframe,
]{geometry}% from http://tex.stackexchange.com/a/280792/43317

\usepackage{blindtext}% dummy text

\begin{document}
\tableofcontents
\Blinddocument
\end{document}


Maybe something like that

\documentclass[
chapterprefix
]{scrbook}[2015/10/03]

\RedeclareSectionCommands[indent=-10mm]{section,subsection,subsubsection}
\renewcommand*{\chapterformat}{%
\hskip -10mm\mbox{\chapappifchapterprefix{\nobreakspace}\thechapter
\autodot\IfUsePrefixLine{}{\enskip}}%
}

\renewcommand{\chapterlineswithprefixformat}[3]{%
#2\hskip -10mm\parbox[t]{\dimexpr\textwidth+10mm}{\raggedchapter#3}%
}

\usepackage[inner=10mm,outer=20mm,nomarginpar
,showframe% shows the page layout
]{geometry}

\usepackage{blindtext}% dummy text

\begin{document}
\tableofcontents
\chapter{Kapitel}
\parbox{\linewidth}{\blindtext}
\section{Abschnitt}
\begin{center}
\blindtext
\end{center}
\Blinddocument
\end{document}


• Great, thanks! I was about to suggest using egreg's geometry options, too, since the other version messed up with my wallpaper layer – Tobias Kienzler Nov 30 '15 at 15:33
• It's a bit late and probably should go to a separate question, but any chance you know how to have the section titles etc. be aligned with the indented text? – Tobias Kienzler Nov 30 '15 at 15:35
• it was not requested, but I added \setlist{leftmargin=5mm,labelwidth=5mm} to decrease lists' indentations – Tobias Kienzler Nov 30 '15 at 15:39
• I have added an example that have the section titles etc. aligned with the indented text. – esdd Nov 30 '15 at 23:37

You can use a trick I learnt some time ago: using the layout feature of geometry

\documentclass{scrbook}
\usepackage{geometry}
\usepackage{kantlipsum}

\geometry{
a4paper,
layoutsize={20cm,27.9cm},% cut 1cm from the width
layoutoffset={1cm,0cm},% put it in the offset
inner=1cm,
outer=2cm,
showframe,
}

\renewcommand{\chapterformat}{%
\hspace*{-1cm}%
\mbox{\chapappifchapterprefix{\nobreakspace}\thechapter \autodot\IfUsePrefixLine{}{\enskip}}%
}

\renewcommand{\sectionformat}{\hspace*{-1cm}\thesection\autodot\enskip}
\renewcommand{\subsectionformat}{\hspace*{-1cm}\thesubsection\autodot\enskip}
\renewcommand{\subsubsectionformat}{\hspace*{-1cm}\thesubsubsection\autodot\enskip}

\setcounter{secnumdepth}{3}

\begin{document}

\chapter{Title}

\kant[1]

\section{A title}

\subsection{A subtitle}

\subsubsection{A subsubtitle}

\kant[2-4]

\section{A title}

\subsection{A subtitle}

\subsubsection{A subsubtitle}

\kant[5-6]

\section{A title}

\subsection{A subtitle}

\subsubsection{A subsubtitle}

\kant[7-15]

\end{document}


• Great, thanks! I basically hybridized your answer and esdd's one due to \RedeclareSectionCommands being shorter ;) – Tobias Kienzler Nov 30 '15 at 15:34
• It's a bit late and probably should go to a separate question, but any chance you know how to have the section titles etc. be aligned with the indented text? – Tobias Kienzler Nov 30 '15 at 15:36
• @TobiasKienzler I think it can be done, but this would move the numbers much more than 1cm (look at the subsubsections). – egreg Nov 30 '15 at 15:39
• Good point, so the overall indentation would have to be increased to, say, 2 cm... I think I saw another question about my additional request, but I can't find it right now :-/ – Tobias Kienzler Nov 30 '15 at 15:42
• ah, I meant this one – Tobias Kienzler Nov 30 '15 at 16:05

Setting \leftskip works for normal paragraphs, but not for lists, which require additional tweaking:

\RequirePackage{enumitem}  % If using a custom class, else replace with \usepackage{enumitem}
\AtBeginDocument{  % Or put this after \begin{document}
\setlength{\leftskip}{10mm}
\setlist[1]{leftmargin=15mm,labelwidth=5mm}
}


This is probably incomplete, e.g. I haven't tested tables and figures with this yet.
