This page was first checked on 2 October 2026. When Instagram changes a spec, the old one is kept here with the date.
Upload photos at least 1080 pixels wide. Instagram keeps any shape between 1.91:1 landscape and 3:4 portrait, so the tallest feed photo is 1080 x 1440 px (1080 by 1440 pixels). Anything outside that range is cropped to fit.
Instagram supports photos from 1.91:1 to 3:4. Portrait at 3:4 (1080 x 1440 px) is the tallest it keeps, and for feed image ads Meta recommends 4:5 at 1440 x 1800 px.
Instagram accepts reels up to a 9:16 ratio, at a minimum resolution of 720 pixels and at least 30 frames per second. For Reels ads, Meta recommends 1440 x 2560 px.
Instagram recommends 420 x 654 px, a 1:1.55 ratio. It also says you can't edit the cover once the reel is uploaded, so set it before you post.
Up to 20 photos and videos in one post. A carousel ad works differently: it takes 2 to 10 cards.
Meta recommends 9:16 at 1440 x 2560 px, and suggests keeping roughly 14% at the top, 35% at the bottom and 6% on each side free of text and logos.
