Pixel density #macOS has been designed to be legible and usable with a pixel density of about 218PPI (pixels per inch) for “Retina” class desktop displays. If a display’s PPI is higher, text and the macOS user interface will be smaller. If a display’s PPI is lower, text and the macOS user interface will be larger. Stray too far from 218PPI and macOS becomes unusable.
