Pixels Per Inch (PPI) — also called pixel density — measures how many pixels fit into one linear inch of a display. Higher PPI means sharper images. Apple introduced the term 'Retina Display' for screens with PPI high enough that individual pixels are not distinguishable at a typical viewing distance (generally ≥ 200–300 PPI depending on screen size and viewing distance).
