Most social media platforms like Instagram, YouTube, and TikTok all require different aspect ratios for video posts. But instead of creating a new video for each platform, resizing the same video can save you so much time and money. It can boost your content’s reach too.

With Clipchamp’s free online video editor, you can quickly change the aspect ratio of a video in seconds. From square 1:1 to 16:9 widescreen, we’ve created popular video ratio presets to suit every platform. You can even remove black borders and reposition awkward cropping.

If you’re ready to resize your video, take a look at our beginner-friendly tutorial below. You can also instantly share your resized videos from inside Clipchamp.

What is an aspect ratio? 

An aspect ratio is the size between the width and height of your video in pixels. Essentially describing your video's shape like YouTube videos are widescreen and Instagram story content is portrait. Aspect ratios are written in the format of “width: height”, for example, the most popular ratio widescreen is 16:9 suitable for YouTube, Vimeo, and Facebook cover videos.

How to change the aspect ratio of a video in Clipchamp

When you create a new video in Clipchamp, the default aspect ratio will be 16:9. You can easily change the dimensions of your video during editing. Follow the steps below to learn how.

Step 1. Click on the 16:9 aspect ratio button

To change the aspect ratio of your entire video, click on the 16:9 aspect ratio button located under the export button.

Step 2. Preview our aspect ratios

9:16, 1:1, 4:5, 2:3, and 21:9 aspect ratio options will appear under 16:9. Hover your cursor over each aspect ratio to preview which dimensions best suit your video.

Step 3. Click on your chosen aspect ratio

To select a new aspect ratio, click on your chosen ratio. We have decided to choose 9:16.

Step 4. Remove borders and black bars around your media

Black bars or borders, called the letterboxing effect, will appear around your video if your media doesn't match the aspect ratio you have selected. 

To remove the black bars, click on your video in the timeline, so it's highlighted green. The floating toolbar will appear next to your video preview window. Click on the fill button.

Your video will automatically stretch/crop into the new aspect ratio.

If any awkward cropping appears, like your main visual isn't in the center of your video preview anymore, simply reposition your video. Click on the video preview, then slide the video around the preview to create a new position.

You can also click the fit button once you have clicked the fill button on the floating toolbar if you wish to keep the video without cropping.

There’s currently no way to set all of your clips to 'fit' simultaneously, so you have to select each individually. However, we're always working to improve the editor and plan to make this more accessible in the future.

Step 5. Export your video

Click on the export button to save your video. Choose your video quality, then your video will start to export. Once your video has finished saving, share it directly from the exporting page to some of our integrations like YouTube and TikTok.
