I would like to reduce the size of the actual citation marks (that you get as a result of cite{key}) and make it half of the size of the regular font. Is this possible? I am using \documentclass[11pt]{beamer} and \usepackage{natbib}. I have tried the solution here:

\renewcommand*{\citesetup}{%
\tiny
\biburlsetup
\frenchspacing}

but I get an error \citesetup undefined probably because I am using natbib. Note: I don't care about the font size in the bibliography. Here's a MWE:

\documentclass[11pt]{beamer}
\usepackage{natbib}

\begin{document}
\bibliographystyle{plainnat}

\begin{frame}
Lorem ipsum \citep{jon90} % I would like this citation to be 50 percent smaller
\end{frame}

\begin{thebibliography}{1}
\bibitem[Jones et al.(1990)]{jon90}
\end{thebibliography}

\end{document}

A quick hack would be to add your desired font to the definition of \citep. In the following example, I added \tiny. 

\documentclass[11pt]{beamer}
\usepackage{natbib}

\makeatletter
\DeclareRobustCommand\citep
{\begingroup\tiny\NAT@swatrue\let\NAT@ctype\z@\NAT@partrue
    \@ifstar{\NAT@fulltrue\NAT@citetp}{\NAT@fullfalse\NAT@citetp}}
\makeatother

\begin{document}
\bibliographystyle{plainnat}

\begin{frame}
Lorem ipsum \citep{jon90} % I would like this citation to be 50 percent smaller
\end{frame}

\begin{thebibliography}{1}
\bibitem[Jones et al.(1990)]{jon90}
\end{thebibliography}

\end{document}

  • +1. An even more robust (though less elegant) approach would be to encase every citation command -- hopefully, there won't be too many of them in a beamer document! -- in a {\tiny ... } wrapper... E.g., ... {\tiny\citep{jon90}} .... – Mico May 13 '17 at 22:24
  • \usepackage{xcolor} \definecolor{citecolor}{gray}{0.4} \let\oldcite\cite \renewcommand{\cite}[1]{{\footnotesize\color{citecolor}\oldcite{#1}}}

    I am using the above. Is it non-robust?
