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.
