Most social media platforms like Instagram, YouTube, and TikTok all require different aspect ratios for sharing video clips. But you don’t need to create a new video for each platformyou can adjust the aspect ratio for videos and instantly share online with the Clipchamp video editor

Our software includes an online video resizer loaded with preset aspect ratios for social media. Resize video without losing quality by following our beginner-friendly tutorial below.

How to change the aspect ratio of a video in Clipchamp

Step 1. Click on the aspect ratio selector

Click the import media button in the your media tab. Upload a video from your computer or connect your OneDrive. 

The default for all new videos in Clipchamp is the 16:9 ratio. But you can easily change video dimensions before or during editing. To change aspect ratio of video, click the 16:9 aspect ratio button at the top right corner of the window, under the export button.

Step 2. Preview our aspect ratios

After you’ve clicked the 16:9 ratio button, the preset options will display below: 9:16, 1:1, 4:5, 2:3, and 21:9. Hover your cursor over the aspect ratio changer to preview. If you’re unsure which one to choose, read our recommendations below.

Step 3. Select your preferred aspect ratio

Click the aspect ratio that best suits your social media platform. For this example, we’ve selected the social-media-friendly 9:16 ratio which has portrait dimensions perfect for mobile viewing.

Step 4. Remove borders and black bars around your media

If your imported clip has a different aspect ratio to your video, it will be framed by black bars. This border effect is called letterboxing. It’s sometimes used so no visuals are lost due to cropping.  

If you would like to remove the black bars, click on your video in the timeline. Once it’s selected, it will be highlighted green, and a floating toolbar will appear alongside your video preview.

Click on the fill button. This will automatically stretch or crop your video so it suits the new aspect ratio.

The automatic adjustment will sometimes cut off some of your video. Simply relocate the frame by clicking the video preview then drag the video to a new position.

If you want to revert the video so it isn’t cropped, just click the fit button — it’s in the same position in the floating toolbar as the fill button.

Clicking the fit button will restore the letterbox effect. You can simply toggle the fill and fit button to see which aesthetic you prefer.

You need to select fit or fill for individual video files.

Step 5. Export your video

Click the export button then choose your video quality. We recommend 1080p for the highest quality viewing experience.  

After you’ve saved your video, you can share it directly to your preferred social media accounts like YouTube or TikTok with our in-app integrations.
