You seem to mean that you would like to see the _computed_ font-size 
values. Firebug apparently has provisions for such inspection in the DOM 
view, but it works in a confusing way, if at all. Yet, I wonder whether 
this is the heart of the matter.

The font size is the total height of a font, and this can be approximated 
by measuring the distance from the lowest descender to the highest 
ascender, though font design generally allows for some small spacing above 
and below (and might, on the other hand, exceed the font height to some 
extent). If Photoshop tells you something essentially different, it does 
not tell you the font size, either in CSS terms or in traditional 
typography terms.

I here what you are saying, but I don't see how that's related to 
measuring font sizes.
