What is Aspect Ratio?

Aspect Ratio definition

Aspect ratio refers to the proportion of the width of an image or video to its height. It is typically represented as a ratio such as 4:3 or 16:9. The most common aspect ratios are 4:3, which is the traditional aspect ratio of standard definition televisions, and 16:9, which is the aspect ratio of high-definition televisions and most modern digital cameras and smartphones.

The aspect ratio of an image or video can have a significant impact on its overall composition and aesthetics. A different aspect ratio can change the way the image or video is framed and the way that the subjects are presented. For example, a 4:3 aspect ratio will have a more "square" frame, whereas a 16:9 aspect ratio will have a more "rectangular" frame.

The aspect ratio of a display or screen refers to the ratio of the width of the screen to the height of the screen, so a screen with a resolution of 1920x1080 has an aspect ratio of 16:9, while a screen with resolution of 2560x1440 has an aspect ratio of 16:9.
