Width squared + height squared = diagonal squared Using this, and the height to width ratio (e.g. 16:9) you can work out the visible area. 16 squared = 256 9 squared = 81 256 + 81 = 337 square root of 337 = 18.358 37 / 18.358 = 2.015 16 x 2.015 = 32.24 9 x 2.015 = 18.14 So, there you have it. A 37", 16:9 screen has a visible area of 32.24" x 18.14". Hav

So for 37" screen you're looking at 32.2"x18.1" edit: beaten
