## Description

This PPI calculator computes your display's Pixels Per Inch (PPI) from its physical size and pixel count. It doubles as an educational guide, explaining what PPI means, how PPI differs from DPI, and why square pixels are assumed in most calculations.

It also covers dot pitch and why its usage has declined, and walks you through calculating PPI and classifying screen resolutions by density.
