Hi,

the best way to do this in versions <0.84 is:

from sugar.graphics import style
pango.FontDescription("sans %d" % style.zoom(72))

This way, it should scale correctly both on the XO and in normal
machines. It's basically the same that Walter does, but should be
simpler.

In Sugar >=0.84, just specify always the same font size and it should
look fine in all screens.

HTH,

Tomeu
