[Tex/LaTex] Change font size of specific chapter

chaptersfontsize

I have set the options of my chapter titles which are fine. However, for one specific chapter title (statement of authorship) I would prefer the title to be smaller than all the preceeding chapter titles before. Is it possible to change the font size, and maybe even the positioning, of one specific chapter title?

\chapter*{Statement of authorship}

Best Answer

You can use titlesec and do this inside a group so that changes are applied only to a chapter

\bgroup
\titleformat{\chapter}{\filcenter}{}{0pt}{\normalfont\large\bfseries}  %% remove \filcenter if not needed
\titlespacing*{\chapter}{0pt}{0pt}{20pt}
\chapter*{Statement of authorship}
\egroup

If the chapter comes at the end, no need of \egroup and \bgroup. Also \filcenter puts the chapter at the center. Change \large to whatever you like.

\documentclass[11pt]{report}
\usepackage{titlesec}

\begin{document}

\chapter{Some chapter}
\bgroup
\titleformat{\chapter}{\filcenter}{}{0pt}{\normalfont\large\bfseries}  %% remove \filcenter if not needed
\titlespacing*{\chapter}{0pt}{0pt}{20pt}
\chapter*{Statement of authorship}
\egroup
\chapter{Some chapter}
\end{document}
