# Changing aspect ratio

> Adjust your project's aspect ratio for different platforms before export.

Different platforms work best with different video shapes. For example, short-form mobile content usually works best in a vertical format.

After recording, you can change your project's aspect ratio before you export.

## Update the aspect ratio

Open your video in the editor. Above the preview, choose the aspect ratio you want to use.

<video aria-hidden="true" src="https://mintcdn.com/pane/s5meEbqU6UGIYa2P/videos/guide/004.mp4?fit=max&auto=format&n=s5meEbqU6UGIYa2P&q=85&s=6d8fdae83c241d979f0515ee3b04ad97" autoPlay loop muted playsInline controls data-path="videos/guide/004.mp4" />

You can choose from these options:

* `Auto`: keeps the original aspect ratio based on the recorded area
* `Wide`: `16:9` for landscape videos
* `Vertical`: `9:16` for mobile-first platforms
* `Square`: `1:1` for social posts
* `Classic`: `4:3` for a traditional video layout
