About this screen PPI calculator
The Screen PPI Calculator lets you calculate pixel density, pixel pitch, and physical screen dimensions. The controls cover only the inputs needed for the result.
You can also use it to compare results after changing one input.
Example
A 3840-by-2160 display with a 27-inch diagonal is about 163 PPI and has a much smaller pixel pitch than a same-size 1080p screen.
Common uses
