Diagonal screen sizes
H = height
W = width
D = diagonal
Screen sizes are sometimes specified by their diagonal size (D). When dealing with large screens
and projection distances at different aspect ratios, it is more convenient to measure screen width
(W) and height (H).
The example calculations below show how to convert diagonal sizes into width and height, at
various aspect ratios.
2.35:1 (Scope)
W = D x 0.92 H = D x 0.39
1.85:1
W = D x 0.88 H = D x 0.47
16:9 = 1.78:1
W = D x 0.87 H = D x 0.49
16:10 = 1.6:1 (native aspect ratio for WUXGA projectors)
W = D x 0.85 H = D x 0.53
