The Trigonometric Math of Display Screens

Because TV marketing sizes highlight diagonal values exclusively, separating actual horizontal and vertical footprints relies on the Pythagorean theorem ($a^2 + b^2 = c^2$). For a 16:9 aspect profile, the conversion equations scale as follows:

$$\text{Width} = \text{Diagonal} \times 0.8716 \quad \Big| \quad \text{Height} = \text{Diagonal} \times 0.4903$$
