PPI - Pixel per Inch


PPI (also called pixel density, pixel per inch) is the measurement of the pixel resolution of any display (or camera or scanner, etc.). It specifies the pixel resolution within a specified space (width * height). The square below his 500 pixels by 500 pixels. By measuring it on screen, the PPI can be calculated:
1. width and height measurement in mm is changed in inch (multiply the mm with 0.03937)
2. the numbers are divided by 500
3. the results indicate the horizontal and vertical PPI
