Your Instagram Reel cover will be shown in a 1:1 aspect ratio in your profile grid and 4:5 on the main feed. However, when someone is viewing your Reel on the dedicated Instagram Reels tab, they’ll see your cover photo in full 9:16. To make sure your Instagram Reel cover looks great no matter where it’s being viewed, we recommend using an image that’s 1080×1920 pixels and keeping any important details within the central 4:5 area.
