### PPI Calculator

PPI 220.53 pixels per inch

# Pixel Per Inch Formula:

PPI = Diagonal in pixels/Diagonal in inches.
Using the screen width, height and the Pythagorean theorem, calculate the length of the diagonal in pixels. Now, divide the length of the diagonal in pixels by the length of the diagonal in inches. ## PIXELS PER INCH CALCULATOR

PPI is a commonly used acronym for Pixels Per Inch. It is basically used as a representation of the measurement of the pixel density of a digital screen. As the name suggests, Pixels Per Inch depicts the number of pixels that can be fitted on a 1-inch line.

This PPI calculator calculates the pixel density or resolution of your screen display on the basis of the screen dimensions and the pixel count.

To calculate the PPI of any display device on this calculator, simply enter the screen width (in Pixels), screen height (in Pixels) and diagonals (in Inch) into the respective fields and click on Calculate button.

#### WHY IS PPI SIZE IMPORTANT?

When a digital image has a higher PPI, you get to see a much better image with finer details.

#### PPI Formula

PPI = Diagonal in pixels/Diagonal in inches ## CATEGORIES OF PIXEL DENSITY

Below are the various categories of pixel density (lowest to highest quality)

Low density, 120 PPI

Medium density, 120-160 PPI

Medium High density, 160-213 PPI

High density, 213-240 PPI

Extra High density, 240-320 PPI

Extra Extra High density, 320-480 PPI
