# How to change sub-caption to small font from capital letters?

I used \usepackage{caption} and \usepackage{subcaption} respectively for the captions. now when i generated the pdf i get the subcaption as

(A),(B),(C)

. I need all of them in small letters like

(a)(b)(c)

and so on.. Where is should make changes? Thanks

• Welcome on tex.stackexchange.com. Can you please provide a minimal working example (MWE) start with \documentclass{} and ends with \end{document} that reproduce the error/problem you need to solve? Thanks – faltfe Aug 9 '18 at 6:38
• yes, i am using \documentclass[12pt,a4paper]{jihmsp}. – faiz Aug 9 '18 at 6:59

With amsart class you can directly get the small-case subcaptions.

\documentclass{amsart}
\usepackage{subcaption}
\captionsetup[subfigure]{labelfont=rm}
\begin{document}
\begin{figure}[h!]
\centering
\begin{subfigure}[]{0.48\textwidth}
\caption{A}
\label{FigPractice1}
\end{subfigure}\par
\begin{subfigure}[]{0.48\textwidth}
\caption{B}
\label{FigPractice2}
\end{subfigure}
\caption{a caption}
\end{figure}
\end{document}


Another possibility is to set the font caption to small-case. This is an option in subcaption package. You must set the option font=small to achieve what you want. But AFAIK, the small-case is the stock option.

\documentclass{article}
\usepackage[font=small]{subcaption}
\begin{document}
\begin{figure}
\begin{minipage}[b]{.5\linewidth}
\centering\large A
\subcaption{A subfigure}\label{fig:1a}
\end{minipage}%
\begin{minipage}[b]{.5\linewidth}
\centering\large B
\subcaption{Another subfigure}\label{fig:1b}
\end{minipage}
\caption{A figure}\label{fig:1}
\end{figure}
\end{document}


• For me, your second solution only worked after adding \captionsetup[subfigure]{labelfont=rm} like in your first solution. – JustBasti Mar 9 '19 at 13:04
• @JustBasti without knowing your preamble, it is difficult to infer. – Raaja Mar 9 '19 at 17:47
