Check out the documentation for the !D graphics system variable.
The fields X_VSIZE, Y_VSIZE give the size of the visible area of
the display; X_CH_SIZE and Y_CH_SIZE give the normal width and height of
a character in device units. X_PX_CM and Y_PX_CM give the approximate
number of pixels per cm in X and Y direction.

Hope this helps.
