Display density
Screen PPI calculator
Measure pixel density and pixel pitch from a screen's resolution and diagonal size.
PPI = diagonal pixels ÷ diagonal inches

PPI vs resolution
More pixels do not always mean a denser screen.
A 4K television and a 4K desktop monitor have the same pixel dimensions, but the smaller desktop panel packs those pixels more tightly. Higher PPI usually produces finer details at the same viewing distance.
diagonal pixels = √(width² + height²)
PPI = diagonal pixels ÷ diagonal inches
pixel pitch (mm) = 25.4 ÷ PPI
PPI = diagonal pixels ÷ diagonal inches
pixel pitch (mm) = 25.4 ÷ PPI
