What is Aspect Ratio?

Different resolutions with the same aspect ratio

Aspect Ratio is the ratio of the width and the height 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 in the form of 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.
