What is PPI?
PPI (Pixels Per Inch) is a measure of a screen's pixel density. It indicates how many pixels are in a line of one inch (2.54 cm). Higher values mean sharper images.
How to measure screen size
Screen size is measured diagonally from corner to corner, excluding the bezel. To calculate physical dimensions, you need to know the aspect ratio (e.g. 16:9) and the diagonal size.
Common aspect ratios
16:9 - Standard for modern TVs and monitors
4:3 - Older displays and some specialized monitors
18:9 - Modern smartphones
21:9 - Ultrawide displays for cinema and gaming
