Well I don't know exactly because I umm... liberated it from work but my first one is roughly 15 inch. Second one is around 3-4 inches bigger I'd say? I'll try and find a tape measure in a bit.
Usually the number is in its model name, so it should be easy enough to find out.
And I really doubt that 15", even the small thing I had as my second was 17", and before that a 19" that eventually replaced the only monitor on another computer here. The one I still use is a 24".
