There's also

(/ (float (display-pixel-width))
   (display-mm-width))

=> 3.78

which might not be available...  Er...  that number surely can't be
right.

(display-mm-width) => 677

This laptop is not almost 70cm wide!  It's a 13" screen, I think, so the
width is like...  30cm?  Something like that.  So perhaps relying on
typical characters is a better idea, anyway.
