Diagonal screen sizes
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.
TRUE 4K (approximately 1.9 : 1)
W
= D x 0.88
H
= D x 0.47
UHD (approximately 1.78 : 1)
W
= D x 0.87
H
= D x 0.49
Notes
D = diagonal
W = width
H = height
