A screen size calculator computes a monitor's or TV's actual width, height, and pixel density (PPI) from the diagonal measurement and aspect ratio. It helps compare displays of different sizes and resolutions.

Vaiheittainen opas

1. 1Use Pythagoras' theorem with the aspect ratio to derive width and height from diagonal
2. 2For 16:9 aspect ratio: height = diagonal × 9 / √(16²+9²); width = height × 16/9
3. 3PPI = √(horizontal pixels² + vertical pixels²) / diagonal inches
