Steps to Change Canvas Size in After Effects

There are two main stages to adjusting the canvas size in After Effects:

The composition settings allow you to change the size of your overall canvas. Here’s how to do it:

Open After Effects, and select the composition you want to alter. Navigate to Composition on the main taskbar, and then select Composition Settings.

In the dialogue box that appears, you’ll see a variety of options. The ones we’re interested in for resizing the canvas are the Width and Height fields under ‘Video Frame Size’.

Type in the width and height you want for your canvas in these fields. These dimensions will be in pixels. Once finished, hit ‘OK’ to save your changes.

2. Adjusting the Solid Settings

If you have solids in your composition, you’ll also need to adjust their size to match your new canvas dimensions. Here’s how:

Select the solid layer that needs resizing, and then navigate to Layer on the main taskbar. Then select Solid Settings.

In the dialogue box that appears, adjust the Width and Height fields to match your new canvas size. Hit ‘OK’ to save your changes.

And that’s it! You’ve successfully changed the canvas size in After Effects.
