Instagram post size in pixels
Instagram displays posts at 1080 px wide, whatever you upload. Every recommended size uses that width and only the height changes:
| Post type | Pixels | Ratio | Smallest Instagram keeps sharp |
|---|---|---|---|
| Tallest portrait | 1080 × 1440 | 3:4 | 320 × 427 |
| Classic portrait | 1080 × 1350 | 4:5 | 320 × 400 |
| Square | 1080 × 1080 | 1:1 | 320 × 320 |
| Landscape | 1080 × 566 | 1.91:1 | 320 × 168 |
| Story / Reel | 1080 × 1920 | 9:16 | 600 × 1067 |
| Profile picture | 320 × 320 | 1:1 | 110 × 110 |
Wider files are scaled down to 1080 px, and anything under 320 px wide is enlarged, which is where blur starts. Stories have their own page: Instagram story size.
Instagram post dimensions and aspect ratios
Instagram's Help Center says the feed keeps photos between 1.91:1 (wide) and 3:4 (tall), that is 1080 × 566 to 1080 × 1440 px, and crops anything outside that range. Many guides still give 4:5 as the tallest shape; that was the limit for years, and it's why 1080 × 1350 became the usual advice. Each post is shown in two places:
- In the feed, a 3:4 post at 1080 × 1440 takes the most screen, with a 4:5 post close behind.
- On your profile grid, every post is a 3:4 tile. A 3:4 post isn't trimmed at all. A 4:5 post loses about 34 px from each side, a square shows only its middle 810 px, and a landscape post shows only the middle 424 px, less than half its width.
The tool draws the grid crop over your image on each feed preset, so you see both views before you download.
1080 × 1440 vs 1080 × 1350 vs 1080 × 1080
- Most photos: 1080 × 1440. The tallest feed post, and nothing is trimmed on the grid. Phone photos are already 3:4, so there's often nothing to crop.
- Existing 4:5 designs: 1080 × 1350. Still fully supported. Keep faces and text inside the middle 1012 px and the grid tile looks right too.
- Product shots and quotes: 1080 × 1080. Still fully supported, but the grid hides 135 px on each side.
- Landscape: 1080 × 566. Only for genuinely wide images. It's the smallest post in the feed and the most cropped on the grid.
In a carousel, every slide takes the shape of the first one, so crop all the images to the same size before you upload.
How to resize a photo for Instagram
- Drop a photo above, paste it with Cmd/Ctrl+V, or try the sample. Drop several and they're all resized at once.
- Pick a preset at the top, or click Use on a row of the size table.
- Drag and zoom until the subject sits inside the grid outline. If the photo won't fit the shape, choose Fit whole image with a blurred or white fill instead of cropping.
- Download a JPG at exactly 1080 px wide. Nothing is uploaded: the photo is processed in your browser.
Why Instagram makes your photo blurry
Instagram resizes anything that isn't 1080 px wide and recompresses every upload. Each of these makes it worse:
- Uploading a huge file. A 4032 px phone photo is shrunk by Instagram's fast resizer. Export at 1080 px yourself so it only gets compressed.
- Uploading something tiny. Under 320 px wide, Instagram enlarges it. Start from the original photo, not a screenshot.
- Heavy sharpening or noise. Fine grain turns into blocky artifacts after compression. Sharpen lightly or not at all.
- Data saver in the app. Turn on "Upload at highest quality" under Settings and activity › Data usage and media quality.
The full explanation, with tests, is in why Instagram ruins photo quality.
Why Instagram crops your post
Two different crops cause most complaints. In the feed, anything taller than 3:4 is cut back to fit, so a 9:16 phone screenshot or a 2:3 camera photo loses its top and bottom. On the profile grid, every post becomes a 3:4 tile, trimming the sides of 4:5, square and landscape posts. Crop to 3:4 yourself, or use Fit whole image to keep the whole picture with a fill around it. The full walkthrough is in how to post a full photo without cropping.
Profile picture
Upload 320 × 320 px. Instagram shows it as a circle only 110 px across in the app, so a tight crop of a face reads far better than a full-body shot or a detailed logo.
