Enter the total number of pixels in long the width and the total number of pixels along the height of a screen into the calculator. The calculator will evaluate and display the aspect ratio of that device.

## Aspect Ratio Formula

The following formula is used to calculate the aspect ratio of a device given the pixels in that screen.

AR = PL / GCD : PH/GCD

- Where AR is the aspect ratio
- PL is the pixels in the length (width)
- PH is the pixels in the height
- GCD is the greatest common denominator between PL and PH

## Aspect Ratio Definition

An aspect ratio is defined as the ratio of pixels along the length to the number of pixels along the height of some screen.

## How to calculate aspect ratio

The following steps are used to solve for the aspect ratio of a device.

- First, measure the total number of pixels along the width.
- Next, measure the total number of pixels along the height.
- Finally, calculate the aspect ratio using the formula above.
