Instagram post size
The sizes for Instagram feed posts in 2026, portrait 1080 × 1350, 3:4 at 1080 × 1440, square 1080 × 1080 and landscape 1080 × 566, with a resizer that crops your photo in the browser.
The most room in the feed for a photo.
Runs in your browser. Nothing you type or upload is sent anywhere.
Instagram displays feed posts 1080 pixels wide and accepts any shape between 1.91:1 (landscape) and 4:5 (portrait). Portrait takes the most of the screen as people scroll, which is why most creators use it.
Your profile grid shows each post as a 3:4 tile, taller than a square and shorter than 4:5. A 4:5 post is trimmed a little at the top and bottom on the grid, and a 3:4 post fits it exactly. Choose 3:4 when the grid matters to you; the 3:4 preview shows the grid crop.
The resizer works on your device. The image is never uploaded.
