Questions tagged [pixel-density]

Pixel density, or resolution, is the measurement of pixels per inch/centimeter of devices such as computer displays, smartphones, scanners, or image sensors.

Pixel density is the number of pixels a display can fit into a fixed distance. This measurement is calculated in pixels per inch (PPI) or pixels per centimeter (PPCM). The higher the pixel density, the crisper the output of the display appears. The human eye can not discern granular detail when it is higher than 300 PPI.

Common Pixel Densities

  • 72/96 PPI - Common for standard definition web graphics
  • 150 PPI - Offset Print Quality
  • 220+ PPI - Retina Displays
  • 300 PPI - Large Scale Print Quality
  • 557 PPI - Samsung Galaxy S6
