Enter the total PPI along the length and the total PPI along the height to calculate the pixel density.

Pixel Density Formula

The following formula is used to calculate the pixel density of a screen.

PD = PPIw * PPIh

  • Where PD is the pixel density in pixels per square inch
  • PPIw is the pixels per inch along the width
  • PPIh is the pixel per inche along the height

Pixel Density Definition

A pixel density is defined as the total number of pixels per square inch of a screen. It can also be defined as the number of pixels per square mm or any other unit of length, but an inch is the most common.

Pixel Density Example

How to calculate a pixel density?

  1. First, determine the PPI along the width.

    Using the calculator linked above or a formula, determine the PPI along the width.

  2. Next, determine the PPI along the height.

    Using the same method calculate the pixels per inch along with the height.

  3. Finally, calculate the pixel density.

    Calculate the pixel density using the formula above.
