[Tex/LaTex] Increase the font size of captions of sub-figures

captionsgraphics

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}

enter image description here

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?

Best Answer

The package subfigure is obsolete and shouldn't be used any longer.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