By Cecilia Hwung | Last Update:

Summary: This post introduces what are 4:3 resolutions and lists all resolutions at 4:3 aspect ratio. Even better, it shows the step-by-step guide of how to change between 4:3 resolutions and 16:9 resolutions with a free and powerful video editing tool - VideoProc Vlogger.

The Difference Between 4:3 and 16:9

4:3 (1.33:1) is a traditional TV display standard, which means the picture is 4 units of width for every 3 units of height. While the 16:9 (1.78:1) aspect ratio is an HDTV screen standard, which means the picture is 16 units of width for every 9 units of height. And HDTV'S 16:9 is 78% wider than its height, allowing bigger pictures to be viewed when compared to the conventional TVs of 4:3 aspect ratio (learn more about Aspect Ratios in Shotkit's guide).

But does that mean 4:3 is totally out of date? Not actually. Both GoPro and DJI Osmo Action cameras provide you with 2.7K 4:3 mode and 4K 4:3 mode. Even Zack Snyder said he wanted the Justice League movie to be shown in a large 4:3 aspect ratio to fill an IMAX screen instead of the widescreen version of films. So what are the 4:3 resolutions?
