A PPI Calculator calculates the pixel density of a screen. It helps evaluate display sharpness.
How to Use Pixel Density Calculator?
A Pixel Density Calculator helps measure how many pixels exist per inch on a screen. It is equivalent to our PPI Calculator for screen parameters.
PPI / Pixel Density Formula
ppi=
√(width_px² + height_px²)diagonal_inches
Where:
width_pxHorizontal Resolution — The width of the screen in pixels.
height_pxVertical Resolution — The height of the screen in pixels.
diagonal_inchesScreen Diagonal Size — The physical diagonal size of the screen in inches.
ppiPPI (Pixels Per Inch) — The calculated screen pixel density.
Compare with DPI Calculator or convert using PPI to DPI.
