I want to specify the figure caption font size in order to follow a stupid standard at my university. I need the font to be Arial (I am using Helvetica because Arial is not available for LaTeX) 11pt. I have found:


I have defined Heveltica as the default font for the whole document, so this constrain is hold. However, I cannot specify the font size. Is there another way to solve this issue?

  • The fontsize for the document or for the captions?

  • 12pt. I have read that when the font size is 12pt, the font=small is 10.95pt, so I guess that solves my issue. Just waiting the one who is going to check that does not notice it. Jul 30, 2015 at 21:22

    If you would do this in Germany, there would be definitely one at the office, taking a ruler and measure the height of your letters ;-)

    The real size depends on the class however, for example the class options 12pt for book.cls will take the values from book12.clo

  • I'm from Ecuador, so here they won't use a ruler, but they would probably like to see some place where you have written the number 11. Jul 30, 2015 at 21:25

You can use \DeclareCaptionFont and \fontsize{<size>}{<baselineskip>}\selectfont (\mdseries in the example below applies \selectfont):




Regular text for comparison
\caption{A test caption for a table}

\caption{A test caption for a figure}


The result:

  • What if I want the global font to be 12pt? I have notice that the solution you have provided solved my issue, but it emans that if I have set 12pt at the documentclass that is going to be the global font? Jul 30, 2015 at 21:42
  • @lmiguelvargasf I updated my answer with a global 12pt. No matter what the global font you select, \captionsetup will override this and give you the desired formatting for the captions. Jul 30, 2015 at 21:44
  • Why do I have to use scaled=0.9 for the package helvet? Jul 30, 2015 at 21:44

    @lmiguelvargasf just to have the Helvetic family fonts match nicely with other families. I don't know exactly what fonts packages are you using, so it might be the case that you wouldn't need to scale the font. Jul 30, 2015 at 21:46
  • I guess that in my case it is not needed. The fonts that I am using are helvet instead of Arial and the other font is Times New Roman (\fontfamily{ptm}\fontseries{b}\fontsize{16}{10}\selectfont), but the last one is just for titles, subtitles (section and subsections). Jul 30, 2015 at 21:50
