Pixel Density Calculator. Perfect for calculating pixels per inch (PPI) and dots per inch (DPI) of any display.
This PPI calculator (pixels per inch calculator) finds the resolution of your display basing on its dimensions and the pixel count. If you want to calculate pixel density of your screen, you will have to know: horizontal and vertical pixel counts and your diagonal screen size
What is pixel density
Pixels per inch (PPI) is a measurement of the pixel density (resolution) of devices in various contexts: typically computer LCD or OLED displays, image scanners, and digital camera image sensors. The PPI of a computer display is related to the size of the display in inches and the total number of pixels in the horizontal and vertical directions.
