What is the Aspect Ratio?

Different resolutions with the same aspect ratio

Aspect Ratio is the width and height ratio of an image, video, or screen. Its value helps you create scalable content that will fit perfectly into any container with the same aspect ratio.

It's formatted as W:H, where W is the width, and H is the height of an image, screen, or container. In digital space, the measurement unit is in pixels.

Common Aspect Ratios

Here is the table of popular aspect ratios and their purpose:

This section helps you calculate the correct resolution width and height proportion based on an aspect ratio that you selected from a commonly used preset or a custom one. Here is the step-by-step guide on how to use this section.

You can choose an aspect ratio from the presets or enter a custom one using the Ratio Width and Ratio Height boxes.

Enter a Width value to find a corresponding Height value and vice versa based on the aspect ratio you chose.

The calculator will automatically calculate every time you change your input.

Find Aspect Ratio tab

Unlike the previous tab, the Find Ratio or Find Resolution Ratio tab helps you to find the aspect ratio value of any screen, image, or video by providing its resolution width and height in pixels format. Here is how to use this tab.

Choose a standard resolution from the presets or enter the resolution width and height.

The calculator will automatically calculate every time you change your input.
