Why is this true?  An em-space isn't necessarily the same as the font
height.  The font height should be the basis for the relative
(percentage) size,  not the em-space width.

I'm guessing that you (unfortunately) picked a font where an em-space is
about the same as the font height.  That's why it's almost right.

Why do people think it's a good idea to specify font sizes in terms of
ems?  I understand percentages, points, pixels, inches, mm's etc.,  but
not en or em spaces.
