I think (but don't have time to check this now) that size 10 for
Courier New is due to how the default fontset is set up on Windows,
see w32-win.el.  If I'm right, then perhaps you could tweak
w32-standard-fontset-spec in your init file such that other fonts are
also chosen with size 10.  (Tweaking that variable needs to be done
from one of the hooks defined by startup.el, I think.)
