Screen objects absolute size

[Keith Clarke]

David, 
Don't forget there is also the possibility of multiple monitors with different pixel densities - and what about large screen TVs or projectors? 

BTW At both ends of the spectrum you will hit limits - screens physically smaller than your app's window size (forcing scrolling or scaling) and large monitors with low pixel density (designed to be viewed from a distance) giving rendering/quality problems.

If absolute viewed size is essential, you would need monitor-level, manual calibration and associated dynamic resizing. Oh, and monitor compatibility standards would need to be stated in the system requirements of the app. 
Best,
Keith..
