It is not that simple, tool bar and/or menu bar may not be an integral number 
of lines.  Also, if a 10 pt font fits 20 lines perfectly on 340 pixels, an 11 
point font doesn't fit an integral number of lines in 340 pixels, it takes 342 
 or 324.
Now most applications don't care, as they aren't text editors, so they don't 
try to display an integral of text lines.  However, gnome-terminal and xterm 
do, and they resize when you change font.
What to do with the excess?  Some strip at the top that picks up the slack? 
Now it got complicated.
