[Tex/LaTex] How to change the font size of TOC, LOF and LOT

Question

I am using

\documentclass[11pt, a4paper]{memoir}

\usepackage{tocloft}
\renewcommand{\cftfigfont}{\small}

\begin{document}
\frontmatter
\tableofcontents
\cleardoublepages
\listoffigures
\cleardoublepage
\listoftables

\mainmatter
\chapter{Introduction}
Lorem ipsum blablabla...
\begin{figure}
\caption[Example]{This is caption 1.}\label{fig:ex1}
\end{figure}
As can be seen in Fig. \ref{fig:ex1}...
\end{document}

But unfortunately, my compiler keeps on telling me:

! LaTeX Error: \cftfigfont undefined.

What's going wrong here? Or: How can I set the font size of the TOC, the LOF and the LOT one pt smaller than the standard font size?

Answer 1

Memoir includes many parts of other packages, including tocloft, so it will be better to search the memoir manual for the specific commands used in that class.

Where K stands for the name of an item type entered into the contents lists (see memoir manual table 9.3), use \cftKfont to adjust the section titles and \cftKpagefont to set the page numbers.

I tidied a few things in the example and added a bit to test the different item types.

\documentclass[11pt, a4paper]{memoir}

% Define a font-switching command
\newcommand{\tocfont}{\textsf}

% Apply the font command to the section titles
\renewcommand{\cftchapterfont}{\tocfont}
\renewcommand{\cftsectionfont}{\tocfont}
\renewcommand{\cftfigurefont}{\tocfont}
\renewcommand{\cfttablefont}{\tocfont}

% Apply it to the page numbers
\renewcommand{\cftchapterpagefont}{\tocfont}
\renewcommand{\cftsectionpagefont}{\tocfont}
\renewcommand{\cftfigurepagefont}{\tocfont}
\renewcommand{\cfttablepagefont}{\tocfont}

\begin{document}
\frontmatter
\tableofcontents
\cleardoublepage
\listoffigures
\cleardoublepage % NOT cleardoublepages
\listoftables

\mainmatter
\chapter{Introduction}
Lorem ipsum blablabla...
\section{Floats}
As can be seen in fig.~\ref{fig:ex1}, the information in table~\ref{table:abc} is valuable.
