How do you change the aspect ratio of a video?

We’ll answer that question in this article. We’ll show you how to easily change the aspect ratio of a video online using Animaker’s free video resizer.

Animaker’s video resizer is a simple tool that lets you quickly resize or change the aspect ratio of your video, and it lets you download watermark-free videos.

But before we show you how, we’ll talk a little about what an aspect ratio is and its importance, and let you in on some popular aspect ratios used by various social media platforms.

Ready? Let’s dive in.

What is an Aspect Ratio?

An aspect ratio is simply the relationship between the width and height of a video. If the width of a video is almost twice as much as its height, then it takes the shape of a rectangle. 

If the width and height of a video are the same, then it’s a square video. That’s why a square video has an aspect ratio of 1:1, to denote that the width and height are the same. 

The most popular aspect ratio is 16:9. If your video is 1280 pixels wide and 720 pixels tall, then it follows an aspect ratio of 16:9.

Why is an Aspect Ratio Important?

Different social media platforms require your videos to be in different aspect ratios.

If you do not follow the recommended aspect ratio, then your video will be automatically resized or cropped to the dimensions that are deemed ideal. 

This might cut off the important parts of your videos and make them look awkward.

And in turn, negatively impact your brand and the engagement of your video.

For instance, if you want to post a video on Instagram, then your video’s aspect ratio needs to be either 1:1 (square) or 4:5 (vertical) if it’s a regular feed video. 

And if you want to post it on IGTV or as a Story, then the aspect ratio needs to be 9:16 (vertical).

Now that we know why an aspect ratio is so important, read on to learn the right aspect ratios for all the popular social media platforms.
