How to use this screen PPI calculator

  1. Enter the screen diagonal and its pixel resolution or viewing preference using the units shown.
  2. Review the calculated totals, units, and assumptions. Check the inputs and units before relying on the result.
  3. Change one input at a time to compare another case, then copy or save the result you plan to use.

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

  • calculate pixel density, pixel pitch, and physical screen dimensions
  • compare results after changing one input
  • save an estimate for planning or comparison
