In my poster doing with baposter, I need to change a font of some figures.

I know that we can use \usepackage[font=small,labelfont=bf]{caption} to cnfigure the font of the caption.

In a specific figure I used this code to put the font to \tiny

      \captionof{figure}{\tiny \textbf{caption}}

I got this result:

enter image description here I need to get the "Figure 3 " as \tiny? can you help me please? sorry I can not post all my code.

Do not make changes directly in the \caption argument; instead, you can use \captionsetup locally (inside the environment); unfortunately? (seee below) tiny is not one of the predefined font sizes, but you can easily implement it using \DeclareCaptionFont; an example including some of your general settings for caption:




\caption{test caption in \texttt{small} font size}

\caption{test caption in \texttt{tiny} font size}


enter image description here

Of course, you can introduce any other font, style, etc. modifications required in \captionsetup.

As a side note, a caption with such small font would be really hard to read.

  • what if I want to set the font size as 11pt? Commented Jul 30, 2015 at 20:51
  • and I have to write that code for every caption figure right ? isn't a way to do this just one time for the whole tex document ? Commented Jul 23, 2017 at 21:00
  • You can define it once and then use in the whole document. Commented Oct 6, 2017 at 19:08
  • It works for me. Thanks
