Yes you are.  Emacs calculates dimensions and coordinates based on the  
frame font because you're setting the "frame size".  You can change  
the fit-frame function to be smarter - it should be pretty easy.   
Convert to pixels based on the default face, then convert back to  
frame chars.
But even so: the "width" of the default face is just an approximation,  
because the default face may well be a variable-width font.

If you do improve fit-frame, please post the new code.  (You can check  
if Drew Adams has an updated version.)
