Screen dimensions calculator
A 27-inch 16:9 panel measures 59.77 by 33.62 centimetres. 23.5 by 13.2 inches. The bezel adds a centimetre or two on each side, and any stand adds more.
How to get panel dimensions
For a desk setup the height figure usually matters more than the width, because it decides whether the top of the screen sits at or below eye level. The ergonomic guidance is that the top of the display should be at or slightly below eye height, which for most people means a 27-inch monitor needs its stand at close to its lowest setting — and a 32-inch one often cannot get low enough without a monitor arm.
