How to Select Your Video’s Aspect Ratio

What is an aspect ratio?

An aspect ratio refers to the proportional relationship between your video’s width and height. Optimize your video for the platform of your choosing by selecting the right video aspect ratio. With Promo, you can make sure that your video performs its best wherever it’s shared with three different ratio publishing options: wide, square and vertical.

Getting Started

1. Select or upload footage

In order to change your video’s aspect ratio, at least one clip or photo for your project needs to be in our editor. You can start from scratch by adding footage from our 110M+ video library or upload your own. To add footage from our library to your project, simply click “Customize” on any footage. You can also preview each clip using the “Preview” button and then click “Use” should you want to add it to our video editor. Don’t forget, you can (and should) merge videos together for your project.

 

2. Choose the video aspect ratio & customize

At this point, you can change the ratio directly from the online editor. Just click on the ratio icon in the top right corner of the page to preview your video in each aspect ratio. Once you’ve made your choice, make the video your own by customizing the colors, styling your captions, adding text to video and more!

3. Save and Publish

Once you’re happy with your video, it’s time to save and publish it. First, click on “Save & Preview” and then on “Publish” to be directed to the publish page. From there, you can download your video to your device, share it with your friends, publish it directly to social media and more.

4. Choose a new aspect ratio

Want to change your video’s size but don’t want to go through the editing process again? No problem! Any video’s aspect ratio can be changed directly from our publishing page. Just select the aspect ratio you want and download your video in all three aspect ratios for free!
