I don't think you can ask Vim for the pixel size of your screen, but you
can do almost as good (after gvim startup, i.e. either in the gvimrc or
in a GUIEnter autocommand):

1. Set some standard 'guifont'
2. :set lines=999 columns=9999
(gvim will now set its screen size to within one character cell of your
monitor size, and adjust the option values accordingly)
3. Compare &lines and/or &columns with some reference values and
increase the 'guifont' size if larger.

Note: There are several incompatible platform-dependent 'guifont'
formats, and each gvim version recognizes only one of them. If someday
you find yourself on Linux and try to set the 'guifont' you set on
Windows, it may or may not give you an error but it will almost
certainly not set the font you expected. See
http://vim.wikia.com/wiki/Setting_the_font_in_the_GUI

Here are a few examples:
GTK2:
:set gfn=Courier\ New\ 11
kvim (obsolete):
:set gfn=Courier\ New/11/-1/5/50/0/0/0/1/0
Photon:
:set gfn=Courier\ New:s11
other X11 (including the now obsolete GTK1):
:set gfn=-*-courier-medium-r-normal-*-*-110-*-*-m-*-*
Mac:
:set gfn=Monaco:h11
Windows:
:set gfn=Courier_New:h11:cDEFAULT


Best regards,
Tony.
