Pixel Density Calculator

About This Calculator

This calculator computes the pixel density (PPI) of a screen based on its resolution and diagonal size. Pixel density is a measure of the resolution of a display, expressed as the number of pixels per inch (PPI) of screen space.

How It Works

  1. Enter the horizontal and vertical resolution of the screen in pixels.
  2. Enter the diagonal size of the screen in inches or centimeters.
  3. Click "Calculate" to compute the pixel density and related metrics.
PPI = √(width² + height²)Diagonal Size (in)

Frequently Asked Questions

What is PPI?

PPI stands for pixels per inch and is a measure of the pixel density of a display. Higher PPI means more pixels are packed into each inch of the screen, resulting in sharper images.

How do I find my screen's resolution?

You can usually find your screen's resolution in the display settings of your operating system or device specifications.

What is dot pitch?

Dot pitch is the distance between the centers of two adjacent pixels, measured in millimeters. A smaller dot pitch indicates a higher pixel density.
