Font size of Figure Caption Header

Question

My question is about changing the font size.

I have to insert two figures side by side. Coming to inserting the captions for the figures individually:

Figure 3: blah blah.....................Figure 4: blah blah...

I am able to change the font size of "blah blah". What I want to know is how to change the font size of "Figure 3" or "Figure 4", say the figure headers or something. I do not know what they are called to search on-line.

Welcome to TeX.sx! While cmhughes' answer is a very good one some classes like KOMA-Script or memoir have their own ways to do these things which is why a minimal working example (MWE) would be a good addition to your question. — cgnieder, Dec 08 '12 at 16:29
It's not necessary to sign your questions (as there is already a box with your username below it). Usually, we don't put a greeting or a "thank you" in our posts. While this might seem strange at first, it is not a sign of lack of politeness, but rather part of our trying to keep everything very concise. Upvoting (with the upward pointing arrow to the left of it; you need 15 reputation points before you can upvote) and accepting it (by clicking on the checkmark) is the preferred way here to say "thank you" to users who helped you. — Stephen, Dec 08 '12 at 16:40

You can do this (and more!) with the caption package

\usepackage[font=small,labelfont=bf]{caption}

will make Figure in bold, and make the caption content small.

Referencing Section 2.3 of the documentation, the size options for font are as follows:

scriptsize
footnotesize
small
normalsize
large
Large

Here's a MWE to play with

\documentclass{article}

\usepackage[font=scriptsize]{caption}
\usepackage{mwe}

\begin{document}

\begin{figure}
\centering
\begin{minipage}{.4\textwidth}
  \includegraphics[width=\textwidth]{example-image-a}
  \caption{My caption here}
\end{minipage}%
\hfill
\begin{minipage}{.4\textwidth}
  \includegraphics[width=\textwidth]{example-image-b}
  \caption{My other caption here}
\end{minipage}
\end{figure}

\end{document}

Thank you for your reply.... I do not know its not working for me...I am actually using Lyx...I tried writing this command in preamble its not working either – Jeshwanth Kundem Dec 08 '12 at 16:38
@JeshwanthKundem you're welcome :) When you say 'not working', does that mean not producing the output, or not compiling, or something else? Perhaps an update is in order: How do I update my TeX distribution? – cmhughes Dec 08 '12 at 16:39
its compiling..I mean to say..i am not getting what I want...you understood my question right...the part "Figure 3" I need to change the font of this – Jeshwanth Kundem Dec 08 '12 at 16:42

@JeshwanthKundem It should work in LyX, too. You should perhaps read the caption manual to find out which options you need. – cgnieder Dec 08 '12 at 16:46
@cmhughes Its working..I figured out how to add the permeable...Thank you very much... – Jeshwanth Kundem Dec 08 '12 at 16:53

Can the size be custom? I am looking for smaller than scriptsize – Manoj Kumar May 06 '15 at 05:44
What If I need to set the caption as \fontfamily{phv} and \fontsize{11}{10}? – lmiguelvargasf Jul 30 '15 at 20:44
And how do you change the font in the referenced text? I would like to see Figure 1 italiced – skan Nov 09 '17 at 10:31
New questions are encouraged/fine – cmhughes Nov 09 '17 at 17:29
One can do \usepackage[font=footnotesize,labelfont=bf]{subcaption} to make this work on subfigures as well. – tommy.carstensen Jan 10 '18 at 13:58
The effect of labelfont=bf is to make the figure label, but not the entire caption appear in bold font. – tommy.carstensen Jan 10 '18 at 13:59
How can you change the size of specific captions? For example I only want to do this on the figures that are side by side? – Michel Nov 25 '22 at 18:39

Not sure why but the answer above did not work for me. If that's the case for you, simply declare:

\usepackage{caption}
\captionsetup[figure]{font=small}

For more detail see: Changing Figure caption text size..
