Frequently asked questions

What size should an Instagram post be?

1080×1350 (4:5) uses the most feed space. 1080×1080 and 1080×566 also work.

Why is my post cropped on my profile?

The profile grid previews posts at about 3:4, so content near the top and bottom of a 4:5 or 9:16 image can be trimmed. Keep important elements in the center.
