How it works
The calculation uses the diagonal and aspect ratio as a right triangle. For metric sizes, convert centimeters with the Cm to Inches Converter.
Screen Size Calculator
Turn a diagonal screen size into approximate width and height.
How screen size works
Screen size is measured diagonally. The calculator uses the aspect ratio to estimate width and height from that diagonal.
Example
A 32-inch screen is not 32 inches wide. The width depends on whether the screen is 16:9, 16:10 or another ratio.
Common mistake
Do not compare desk fit by diagonal alone. Width and height decide whether the screen fits the space.
