How it works
The comparison uses the active rectangular display area, excluding bezels, stands and mounting hardware. It does not calculate viewing distance, pixel density or image quality. Curved and non-rectangular displays may need manufacturer dimensions for installation. Aspect ratios are entered as width to height, such as 16:9, 21:9 or 4:3.
The formulaWidth = diagonal × aspect width / √(aspect width² + aspect height²)
Height = diagonal × aspect height / √(aspect width² + aspect height²)
Visible area = width × height
Height = diagonal × aspect height / √(aspect width² + aspect height²)
Visible area = width × height
