# Change the font of figure captions

I would like to italicize my figure captions and make them smaller. How can I do that?

-

It can be done by loading the `caption` package and by choosing options or `\captionsetup`, for instance:

``````\usepackage[font={small,it}]{caption}
``````

The caption package provides a lot more feature and is very well documented.

How can you make it even smaller? – Malabarba Dec 15 '10 at 22:29
Instead of `small`, you could choose `footnotesize` or `scriptsize` as property for the `font` option. – Stefan Kottwitz Dec 15 '10 at 22:42
Is there a simple way to get a size in between footnotesize and small? Small is just slightly to big. – Marten Jun 19 '14 at 20:07
what is the size of `small`? is it relative to the main font size? – Ahmad May 25 at 15:18

KOMA-Script provides commands for customizing fonts of certain elements:

• `\setkomafont{element}{commands}`
• `\addtokomafont{element}{commands}`
• `\usekomafont{element}`

The latter can be used for using the configured font for further elements. Among the supported elements are `caption` and `captionlabel`.

So here we could write:

``````\setkomafont{caption}{\footnotesize\itshape}
\setkomafont{captionlabel}{\usekomafont{caption}}
``````

This answer requires familiarity with KOMA-Script. I went through the manual and I still don't understand whether I should use a certain package or what a minimum working example looks like. – kon psych May 8 '15 at 7:08
@kon I use scrartcl as document class, and it was very easy to apply. Just put the two lines in the header, no extra package necessary. – luckyrumo Jun 27 '15 at 22:19

The memoir document class has this baked in. The provided functionality allows adjustments to the following parameters:

• The font commands used for the caption label (the `Figure x:` part).

• The delimiter that separates the label from the caption.

• The font commands used for the caption text that follows the label.

• The alignment/justification of the caption (left, right, hanging indent, etc)

And much more. See section 10.6 of the memoir manual for full details.

Memoir also includes support for things such as sub-captions and side-captions. Chapter 10 of the manual describes all this and much more.
