The **“PPI Calculator / DPI Calculator**” tool is a useful utility for calculating the Pixels Per Inch (PPI) and Dots Per Inch (DPI) of a display device. By inputting the screen diagonal, a unit of measurement (inches, centimeters, or millimeters), and selecting the screen resolution, the tool provides accurate PPI and DPI values.

## How to Calculate PPI Simple Steps With Formula

Here’s a simple and concise explanation of how to calculate PPI (Pixels Per Inch) with the formula:

- Determine the number of pixels along the width or height of the screen, whichever is easier to measure.
- Measure the diagonal length of the screen in inches.
- Use the following formula to calculate PPI:PPI = Number of Pixels / Diagonal Length in inchesIn this formula, divide the number of pixels by the diagonal length measured in inches.

## PPI vs. DPI

PPI and DPI are two related but distinct terms used to describe the resolution or pixel density of a display:

- PPI (Pixels Per Inch): PPI refers to the number of pixels (individual color dots) that are present per inch on a screen. It measures the pixel density or the level of detail that can be displayed. Higher PPI values generally indicate sharper and more detailed visuals.
- DPI (Dots Per Inch): DPI originally referred to the number of dots that a printer could produce per inch on a physical page. However, in the context of digital displays, DPI is often used interchangeably with PPI. In this context, DPI represents the pixel density or resolution of a display device, similar to PPI.

While PPI specifically refers to the number of pixels per inch on a screen, DPI can have broader applications and is often used in the context of printing or scanning devices.
