Changing the video aspect ratio to the proper one is the key if you want your videos to look comfortable when you post them. Social media platforms have a required aspect ratio - widescreen, square, portrait, landscape, etc. If it is not followed, it will be automatically resized to the required ratio. It may cut off important parts of your videos, so it can be really frustrating if you don't know what aspect ratio to use and when. Check out the detailed description of different video aspect ratios and ways to change video aspect ratio in the following parts.

Part 1: Detailed Introduction to Different Video Aspect Ratio

Before changing the video aspect ratio, you need to know what is an aspect ratio in a video? It is simply the relationship between the video’s width and height. It describes the video’s shape, like a portrait for an Instagram Story or videos on TikTok, and a widescreen for YouTube videos. As mentioned, it is the critical element to make your video look comfortable and pleasing in the eyes of the viewers.

Aspect ratios are written in the format of "width: height" to illustrate, one example of an aspect ratio is 16:9. It doesn't mean that it has a pixel size of 16 x 9 since it would be minimal in size. A 1280 x 720 pixels wide video follows an aspect ratio of 16:9 - a high-definition resolution. See below the most famous aspect ratios that are used for different types of videos and change the video aspect ratio according to them.

Suppose you do not follow the required aspect ratio depending on what platform you use to post. In that case, it will be automatically cropped, which may cut off the essential parts of the videos, resulting in a negative engagement of your video. So, if you want to post an IG Story, use the 9:16 aspect ratio. Ready to change video aspect ratio? Read the following part to learn the best way to change video aspect ratio on Windows PC and Mac.
