I'm probably just ignorant of this sort of shortcut you've used to obtain the difference between their areas; I'm definitely no mathematician. But could you help me out on this a bit? (Perhaps you're effectively making 2 squares out of the diagonals, by multiplying them by themselves, and this somehow can deliver the overall difference in their areas. ? )
Oh, BTW, I'm just referring to the relative screen areas, not the part about trying to figure in how much more text based on the increased resolution.

You are right. It works when the length to width ratio is same in both the devices. Usually most of the devices have similar shape. Even if they had a slightly different shape - the difference will be very less, so this shortcut works
