Full specification
Dimensions
1920 x 1080 px
Aspect ratio
16:9
Accepted formats
PNG recommended (standard for Figma frame exports). Figma does not publish a strict format restriction for Community thumbnails.
Requirements
Figma provides a built-in file-cover frame preset, under the Frame tool’s Community section in the right sidebar, sized correctly, so you don’t have to set up the canvas size by hand.
You can add up to 9 additional images beyond the thumbnail -- these appear in a media carousel on the file’s Community page.
Figma’s own file format and max file size guidance for thumbnails isn’t published -- left blank rather than guessed.
Common reasons submissions get rejected
Designing the thumbnail at an arbitrary canvas size instead of using Figma’s own file-cover frame preset.
Cramming too much text into the thumbnail -- Figma’s own design guidance is to keep thumbnail text short and easy to scan.
