# Increase the font size of captions of sub-figures

I have the following latex code to show two sub figures and their captions.

\documentclass{article}

\usepackage{amssymb}
%\usepackage{graphicx}
\usepackage{caption}
\usepackage{subfigure}

\usepackage[demo]{graphicx}

\begin{document}

\begin{figure}[]
\centering
\subfigure[Figure 1]{
\includegraphics[width=0.5\textwidth]{}
\label{figure:fig1}
}
\subfigure[Figure 2]{
\includegraphics[width=0.5\textwidth]{}
\label{figure:fig2}
}
\end{figure}

\end{document}


I want to increase the font size of the sub-captions and I have tried this:

\begin{figure}[]
\centering
\subfigure[\Large{Figure 1}]{
\includegraphics[width=0.5\textwidth]{}
\label{figure:fig1}
}
\subfigure[\Large{Figure 2}]{
\includegraphics[width=0.5\textwidth]{}
\label{figure:fig2}
}
\end{figure}


As shown in the above figure, this only makes the font of "Figure 1" part bigger, but not the "(a)" part of the caption of sub-figures.

How to increase the font size of sub-figures?

• The package subfigure is completely outdated. Use subfig or subcaption – user31729 Jun 25 '16 at 15:50

The package subfigure is obsolete and shouldn't be used any longer.

There are two alternatives: subfig or subcaption.

Use \usepackage[font=Large]{subfig} for larger caption labels, for example.

\documentclass{article}

\usepackage[demo]{graphicx}

%\usepackage{amssymb}
\usepackage{caption}
\usepackage[font=Large]{subfig}

\begin{document}

\listoffigures

\captionsetup[figure]{font=Large}

\clearpage
\begin{figure}

\centering
\subfloat[My first figure]{%
\label{figure:fig1}
\includegraphics[width=0.5\textwidth]{}
}

\subfloat[My second figure]{\label{figure:fig2}\includegraphics[width=0.5\textwidth]{}}
\caption{My first figure}
\label{myfullfigure}

\end{figure}

In \subref{figure:fig1} we see this and in \ref{myfullfigure} we see all

\end{document}


The subcaption package provides subfigure etc. environments, which are easier to use, in my point of view

• Thanks, that works. I have another issue, though. When I add more than 2 sub-figures, they do not appear one under the other. Any ideas? – Co Koder Jun 25 '16 at 16:38
• @CoKoder - Have you tried inserting a blank line between the subfigures? – Mico Jun 25 '16 at 16:46
• yes, I did. That did the trick, but subfigure package seems to do this automatically. Is there a better way than inserting a blank line? – Co Koder Jun 25 '16 at 16:49
• @CoKoder: That's the way how TeX or LaTeX inserts a blank line: Leaving a blank line. Too easy? ;-) – user31729 Jun 25 '16 at 17:41
• @ChristianHupfer Can you add an example using subcaption, since for many it's the preferred option? – Ela782 May 9 '17 at 17:10
