Can anyone tell me how I can change the font size of the \lstlistoflistings?

Question

I've suceeded in creating list of listings, but the font of the /lstlistoflistings is too large. I don't have any idea how to decrease it.

Answer 1

For the title a quick workaround is to include a size command in the name of the list:

\documentclass{article}
\usepackage{listings}
\begin{document}
\begin{lstlisting}[float,caption=A listing]
This is a listing
\end{lstlisting}
\def\lstlistlistingname{\small Listings}
\lstlistoflistings
\end{document}

Changing the font size of the list items is more difficult. You can copy the definition of \lstlistoflistings from the package source and add a size command just before the \tableofcontents command in that definition. Also include \makeatletter and \makeatother around the redefinition because the code contains @ symbols. Here I used \footnotesize for the list items.

MWE:

\documentclass{article}
\usepackage{listings}
\begin{document}
\begin{lstlisting}[float,caption=A listing]
This is a listing
\end{lstlisting}
\begin{lstlisting}[float,caption=Another listing]
This is a listing
\end{lstlisting}
\def\lstlistlistingname{\small Listings}
\makeatletter
\def\lstlistoflistings{%
\bgroup \let\contentsname\lstlistlistingname%
\let\lst@temp\@starttoc%
\def\@starttoc ##1{\lst@temp {lol}}%
\footnotesize% here the size command is added
\tableofcontents%
\egroup}
\makeatother
\lstlistoflistings
\end{document}
