Frequently asked questions
Why does my photo get cropped differently in the grid?+
Instagram's profile grid always crops to a square (1:1), even if your original post is portrait (4:5) — this preview shows both so you can check nothing important gets cut off in the grid view.
What size should a Reel cover be?+
Instagram recommends 1080×1920px (9:16) for Reels covers and video content.
