It depends on the GUI toolkit you are using.

For example in Tkinter you can use methods winfo_screenwidth() and
winfo_screenheight() of your widget if you need the size in pixels.
winfo_screenmmwidth() and winfo_screenmmheight() return the size in
millimeters.

For other toolkits look at the corresponding documentation.
