Resizing your scene means choosing the right ratio or format for the support targeted (eCommerce site, social networks, print, etc.), and in particular portrait versus landscape orientation.
Resize scene with custom ratio
You can resize your scene as you wish. You can choose a set ratio or add your own custom ratio.
Here's how to resize your scene with a custom ratio:
Click on the current dimension (e.g., 1920x1080) in the toolbar at the bottom of the studio
Go to the “Custom” tab, and enter the desired ratio in the designated fields
Save it, giving it a name for easier access
The working window resizes automatically
