4:3 Ratio Calculator

Calculate the height of your desired fullscreen 4:3 aspect ratio by entering the desired width of the image or video you want to resize.

The 4:3 aspect ratio is commonly known as the fullscreen aspect ratio. The 4x3 (1.33:1) format became the first standard ratio for televisions and computer monitors as it was easy to use due to the camera formats.

In the past, many videos and movies were recorded in the 4:3 aspect ratio, so they didn't need to be converted for TV release.

It wasn't until the 1990s and 2000s that the widescreen 16:9 ratio became more popular as a video format.
