Not sure what you mean by that: attributes don't care about remapping,
because remapping doesn't change the attributes, it only changes their
values.

I think you want
(aref (font-info (face-font 'default)) 2)
But note that font's size and its "width" (which is actually the
average width recorded in the font file) are not identical. We don't
have a Lisp API to get the average width of a non-default font;
perhaps we should.
