Instagram Reels Size and Thumbnail Preparation

Instagram Reels are watched in a vertical mobile environment. Prepare the video, cover, and thumbnail area so important text and subject stay visible.

Instagram Reels safe area diagram showing central subject placement and edge zones. — Example diagram: keep key text and the main subject away from edge and bottom interface areas.

Use a vertical-first layout

Design for a tall mobile screen. Keep the main subject centered and avoid placing critical text near edges.

Thumbnail and cover planning

The cover should explain the Reel quickly without needing audio. Use short text and a clear focal point.

Safe area mindset

Captions, buttons, usernames, and overlays can reduce visible space. Keep essential information away from the bottom and side edges.
