# Can I change chapter font at the end of the book?

In this example :

\documentclass{book}

\begin{document}

\chapter{Chapter one}

\chapter{Chapter two}

\chapter{Chapter three}
New font and distance from the text here

\end{document}


I would like to set a different style for my last chapter title, ie different font and distance from the text. Is it possible to do a \renew command ?

• you can use all the stuff from titlesec right before that last chapter – A Gold Man Nov 9 '17 at 21:17
• Yes, this is possible, for example, by redefinition of \@makechapterhead. – user31729 Nov 9 '17 at 21:17
• I already have the code for that, but it's not working. – alfred Nov 9 '17 at 21:21

You can use titlesec for making the changes easier.

\documentclass[
openany,% for the picture
oneside,% for the picture
]{book}
\usepackage{fontspec}
\usepackage{titlesec}
\usepackage{showframe} % for the picture

\newfontfamily{\cambria}{Cambria}
\newfontfamily{\antiqua}{Futura}[ % use Book Antiqua, I don't have it
NFSSFamily=antiqua,
]

\newcommand{\specialchapters}{%
\titleformat{\chapter}[display]
{\normalfont\cambria\huge\bfseries}
{\chaptertitlename\ \thechapter}
{20pt}
{\Huge}%
\titlespacing*{\chapter}{0pt}{50pt}{10pt}%
\renewcommand{\familydefault}{antiqua}%
\normalfont
}

\begin{document}

\chapter{Chapter one}
Distance from the text

\specialchapters

\chapter{Chapter two}
New font and distance from the text here

\end{document}


I used the options to \documentclass just for showing the two chapters side by side, with also the help of shoframe. Instead of Book Antiqua, that I don't own, I use a distinctive font just for showing that the setting is honored.

Thanks to Christian Hupfer's suggestion and based on previous answer I got to this solution :

\documentclass{book}
\usepackage{fontspec}

\begin{document}

\chapter{Chapter one}

\chapter{Chapter two}

\makeatletter
\vspace*{50\p@}
{%
\parindent \z@ \raggedright
\setmainfont{Cambria}  % <- change 'Chapter 3' font here
\ifnum \c@secnumdepth >\m@ne
\if@mainmatter
\large \normalfont \@chapapp \space \thechapter \par
\nobreak \vskip 2\p@
\setmainfont{Book Antiqua} % <- change title font here
\fi
\fi
\interlinepenalty \@M \fontsize{34}{38}\selectfont \normalfont #1\par
\nobreak \vskip 40\p@ % <- change vertical distance from text here
}}
\makeatother

\chapter{Chapter three}
New font and distance from the text

\end{document}
