Facts and prices checked on 2026-11-06.
Pick a format, drop your photos and download JPGs at the exact pixel size Instagram expects, so the app does not crop or soften them on its own. Crop to fill and move the crop with the slider, or fit the whole photo with a border. Everything runs in your browser.
Instagram sizes

|---|---|---|
| Portrait 3:4 | 1080 × 1440 | Feed posts that show uncropped in the profile grid |
| Portrait 4:5 | 1080 × 1350 | Feed posts, ads and most scheduling tools |
| Square 1:1 | 1080 × 1080 | Classic feed posts |
| Landscape 1.91:1 | 1080 × 566 | Wide shots in the feed |
| Story and Reel 9:16 | 1080 × 1920 | Stories, Reels covers, full-screen |
Instagram does not publish one official size table. These are the sizes current guides from social media tools agree on, checked on 6 November 2026. Since the profile grid switched to tall 3:4 tiles, a 3:4 post is the only feed format that is not cropped in the grid.
For carousels
Export every slide in the same format. Instagram gives the whole carousel the shape of the first slide, so mixed formats get cropped.
Clients want the full-resolution files, not the Instagram version: deliver both from one Galerly gallery.

Which format should I use for portraits?
3:4 at 1080 × 1440 if you care how the profile grid looks; 4:5 at 1080 × 1350 if you also run the post as an ad.
Why export at 1080 pixels wide?
Instagram shows posts at 1080 pixels wide. A larger file is scaled down by the app, often less sharply than doing it yourself.
Are my photos uploaded?
No. They are cropped and exported in your browser and stay on your device.
