You can change video aspect ratio with video editing software like VideoStudio. Follow along with our tutorial below to learn the easiest way to change video aspect ratio. Traditionally, monitors and televisions and camera displays have an aspect ratio of 16:9 - a rectangle shape (width by height). You probably remember back when a TV was a lot small - 4:3 - and today there’s plenty to be said about designing vertical videos for mobile devices or square videos for Instagram. Changing the aspect ratio of your video gives you plenty of options to play with and can really expand your video arsenal. Let's get to work.

The video editing software supports editing videos with 16:9, 4:3, 1:1, 9:16 and 3:4 aspect ratios. You can publish your edits to YouTube, Facebook, Instagram, TikTok and other social media. Besides, the rendered video can also be burned to DVDs and imported into your iOS and Android devices. Simply share any video as you want.
