What aspect ratios does Instagram support?
Instagram aspect ratios are the width-to-height shapes posts can use: square 1:1, portrait 4:5 and landscape up to 1.91:1 for feed posts, and vertical 9:16 for reels and stories.
Detailed Explanation
Uploading media in the wrong shape leads to awkward cropping or black bars. For the feed, 4:5 portrait takes up the most screen space, which is why many creators use it. Reels and stories fill the screen at 9:16. Carousels use one ratio for all slides, set by the first item. Good schedulers include a cropper so every image is the right shape before it is published.
How It Works Step-by-Step
Choose the format: feed post, carousel, reel or story.
Crop the media to the matching ratio (1:1, 4:5, 1.91:1 or 9:16).
For carousels, keep every slide in the same ratio.
Preview before scheduling to check nothing important is cut off.
How Teams Use This in Production
"A restaurant’s landscape food photos were getting cropped awkwardly. Re-cropping them to 4:5 portrait in the scheduler made dishes fill the screen in the feed."
Why It Matters for Growth & Revenue
The right ratio makes content look professional and take up more space in the feed, which helps it stand out.
