I would like to change the font size of all captions in my thesis. The solutions I saw, were referring to use Caption package and font=footnotesize. However, this option is not suitable for me while I want to have the font exactly adjusted. As an example, the font size of the text is 11pt and I want the captions to be either 10pt or 9pt.

    If 11pt is the normal text font size, then \small is 10pt and \footnotesize is 9pt.

  • I could not apply small to every captions. However, what Ulrike suggested works. Thanks for your comment. @campa

You can define a special size with \DeclareCaptionFont:



\captionof{figure}{Normal size}

\captionof{figure}{Special size}

  • This works. Thanks Ulrike.
