Changing the image caption size


I encounter a strange situation, with image captions. In the edit mode their font size is smaller than a normal text, which I think is normal, but in the preview and after being published their font size is the same as the font size of the post text which is a bit confusing. Btw. bold and italics funcions for these captions work well.

Can I change it somehow?
