[Tex/LaTex] Sectioning chapter, section, subsection formatting

formattinghorizontal alignmentnumberingsectioning

I'd like some help with the formatting of chapter, section and subsections.

I am using the report document class and I'd like to generate the following chapter, section and subsection formatting in the document.

Each (and only) chapter page should have a 2in top margin. Chapters, Section and Subsection title should have the same font size as text.

Then, the format should be as follows:
Capital Roman Numbering for chapters, chapter title should be centered and display only the number dot the title of the chapter, i.e.

I. Introduction

Lower case roman numbering for section also centered and should display Chapter number dot Section Number dot Section title, i.e.

I.i. Section in Introduction chapter

And finally the subsection should not be numbered at all and left justified.

Best Answer

This is readily achievable using sectsty and some manual adjustments for the \chapter setting:

\documentclass{report}

\usepackage{sectsty}

% http://tex.stackexchange.com/q/59726/5764
\allsectionsfont{\centering\normalsize\bfseries}% All sections are centred/normal size/bold
\subsectionfont{\normalsize\bfseries}% Correct \subsection formatting

\renewcommand{\thechapter}{\Roman{chapter}}% Chapter number formatting
\renewcommand{\thesection}{\thechapter.\roman{section}}% Section number formatting

% http://tex.stackexchange.com/q/42161/5764
\setcounter{secnumdepth}{1}% Only number up to \section

\makeatletter
% http://tex.stackexchange.com/q/24439/5764
\renewcommand{\@seccntformat}[1]{\csname the#1\endcsname.~}% Add period after section number in title

% Taken from http://mirrors.ctan.org/macros/latex/contrib/sectsty/sectsty.dtx
\def\@makechapterhead#1{%
  \vspace*{2in}% Formerly \vspace*{50\p@}%
  {\parindent \z@ \raggedright \normalfont
    %\ifnum \c@secnumdepth >\m@ne
    %    \huge\bfseries\SS@chapnumfont{\@chapapp\space \thechapter}%
    %    \par\nobreak
    %    \vskip 20\p@
    %\fi
    \interlinepenalty\@M
    %\raggedright \normalfont
    \Huge \bfseries \SS@chaptitlefont {\thechapter.~#1}\par\nobreak
    \vskip 40\p@
  }}
\makeatother

\begin{document}

\chapter{A chapter}
Some text in this chapter.

\section{A section}
Some text in this section.

\subsection{A subsection}
Some text in this subsection.

\end{document}

The 2" margin for \chapter-pages only is measured from the top of the text block. As such, the regular text block margins relative to the page still remains.

References to other questions relating to the above changes are scattered within the code.

[Tex/LaTex] Centering chapter/section/subsection

Your definition will work for sections and subsections, but not for chapters and has a potential drawback in that you loose control over the optional argument for the sectional units; with your definitions, the optional argument will always be equal to the mandatory argument and that might not be desirable.

Here's one option using the sectsty package:

\documentclass{book}
\usepackage{sectsty}
\usepackage{lipsum}

\allsectionsfont{\centering}

\begin{document}

\chapter{Test Chapter}
\section{Test Section}
\lipsum[4]
\subsection{Test Subsection}

\end{document}

enter image description here

And here's now an option using the titlesec package:

\documentclass{book}
\usepackage[center]{titlesec}
\usepackage{lipsum}

\begin{document}

\chapter{Test Chapter}
\section{Test Section}
\lipsum[4]
\subsection{Test Subsection}

\end{document}

These solution horizontally centers the headings for all sectional units; the packages provides commands to modify the formatting on a per-level basis. Here's the code (using sectsty) to apply the change only to chapters, sections and subsections:

\documentclass{book}
\usepackage{sectsty}
\usepackage{lipsum}

\chapterfont{\centering}
\sectionfont{\centering}
\subsectionfont{\centering}

\begin{document}

\chapter{Test Chapter}
\section{Test Section}
\lipsum[4]
\subsection{Test Subsection}

\end{document}

[Tex/LaTex] titlesec ToC formatting — capitalization, subsection numbering for sections, title formatting

Here's one way to do it:

\documentclass[12pt]{article}
\usepackage{blindtext}
\usepackage{etoolbox}
\usepackage{titlesec}
\usepackage{titletoc}

\titleformat{\section} % command
[hang]                 % shape
{\normalsize\bfseries} % format
{\thesubsection}       % label
{1em}                  % Spacing between label and title
{\MakeUppercase}       % before code
\titlespacing{\section}% Set the spacing around the title
{0pt}                  % Left
{0pt}                  % Above
{0pt}                  % Below

\newcommand\RegToCEntries{
  \titlecontents{section}[2em]
    {\vspace{12pt}}
    {\normalfont\normalsize\contentslabel[\thecontentslabel.0]{2em}\uppercase}
    {\hspace*{-2em}\uppercase}
    {\titlerule*[.75em]{.}\contentspage}
}
\newcommand\AppToCEntries{
  \titlecontents{section}[0em]
    {\vspace{12pt}}
    {\normalfont\normalsize\contentspush{\MakeUppercase{\appendixname}}%
      \contentslabel{-1em}\hspace{2em}\makebox[1em][l]{--}%
    }
    {\hspace*{-2em}}
    {\titlerule*[.75em]{.}\contentspage}
}
\AtBeginDocument{\RegToCEntries}
\pretocmd{\appendix}{\AppToCEntries}{}{}
\patchcmd{\tableofcontents}
  {\contentsname}
  {\hfill\MakeUppercase{\contentsname}\hfill\null}
  {}
  {}

\titleformat{\subsection} % command
[hang]                 % shape
{\bfseries\normalsize} % format
{\thesubsection}       % label
{1em}                  % Spacing between label and title
{}                     % before code
\titlespacing{\subsection}% Set the spacing around the title
{0pt}                  % Left
{0pt}                  % Above
{0pt}                  % Below

\titleformat{\subsubsection} % command
[runin]                % shape
{\bfseries\normalsize} % format
{\thesubsubsection}    % label
{1em}                % Spacing between label and title
{}                     % before code
[.]                    % after code

\begin{document}

\tableofcontents
\clearpage% just for the example
\blinddocument
\appendix
\section{A test appendix}
\section{Another test appendix}

\end{document}

The result:

Explanation

Center the ToC title.

I used the etoolbox package to patch \tableofcontents:

\patchcmd{\tableofcontents}
  {\contentsname}
  {\hfill\MakeUppercase{\contentsname}\hfill\null}
  {}
  {}

Formatting for section entries.

I defined two commands \RegToCEntries and \AppToCEntries:

\newcommand\RegToCEntries{
  \titlecontents{section}[2em]
    {\vspace{12pt}}
    {\normalfont\normalsize\contentslabel[\thecontentslabel.0]{2em}\uppercase}
    {\hspace*{-2em}\uppercase}
    {\titlerule*[.75em]{.}\contentspage}
}
\newcommand\AppToCEntries{
  \titlecontents{section}[0em]
    {\vspace{12pt}}
    {\normalfont\normalsize\contentspush{\MakeUppercase{\appendixname}}%
      \contentslabel{-1em}\hspace{2em}\makebox[1em][l]{--}%
    }
    {\hspace*{-2em}}
    {\titlerule*[.75em]{.}\contentspage}
}

The first one gives the desired formatting for regular sections and the seccond one, for sections in appendix; I added Appendix using \contentspush. The first command is used \AtBeginDocument:

\AtBeginDocument{\RegToCEntries}

and the second one is applied automatically after invoking \appendix:

\pretocmd{\appendix}{\AppToCEntries}{}{}

Suggestion

Your code sets

\titlespacing{\section}% Set the spacing around the title
{0pt}                  % Left
{0pt}                  % Above
{0pt}

which suppresses spacing around section titles; I'd suggest you to use positive values in the last two arguments so section titles will have better vertical spacing with respect to the surrounding text.
