What are the Instagram story dimensions?
1080 x 1920 pixels at 9:16. That fills the screen on virtually every phone. Keep text and stickers away from the top and bottom edges, roughly 250 pixels each, where Instagram's own interface sits.
Instagram Image Sizes (2026)
The best Instagram post size in 2026 is 1080 x 1440 pixels at 3:4, which matches the new profile grid exactly. Stories and Reels are 1080 x 1920, and the profile picture is 320 x 320.
Instagram retired the square profile grid. Profiles now preview every post at a 3:4 portrait crop, and since 2026 you can upload feed images at 3:4 natively, so a 1080 x 1440 image displays uncropped in both the feed and the grid. The older 4:5 and square sizes still work in the feed, but the grid trims them.

Instagram Feed Post Sizes (2026)
All feed uploads render at 1080 pixels wide. The height decides how much of the screen, and the grid, the post gets.
| Format | Size (px) | Ratio | Notes |
|---|---|---|---|
| Portrait post (new default) | 1080 x 1440 | 3:4 | Matches the current profile grid exactly, so nothing gets trimmed anywhere. The best default in 2026. |
| Portrait post (classic) | 1080 x 1350 | 4:5 | Still fully supported in the feed, but the grid preview trims a little from the top and bottom. |
| Square post | 1080 x 1080 | 1:1 | The grid crops squares to 3:4, cutting the left and right edges. |
| Landscape post | 1080 x 566 | 1.91:1 | The smallest footprint in feed and the heaviest crop in the grid. |
Instagram Carousel Sizes
Every slide in a carousel shares one aspect ratio, and the first slide sets it.
| Format | Size (px) | Ratio | Notes |
|---|---|---|---|
| Carousel slide (recommended) | 1080 x 1350 | 4:5 | The most common choice and the safest across devices. |
| Carousel slide (3:4) | 1080 x 1440 | 3:4 | Newer option with about 7 percent more vertical room than 4:5. |
| Carousel slide (square) | 1080 x 1080 | 1:1 | Classic seamless-panorama format, and what most split tools export. |
Instagram Story and Reel Dimensions
| Format | Size (px) | Ratio | Notes |
|---|---|---|---|
| Story | 1080 x 1920 | 9:16 | Keep text inside the middle of the frame; the top and bottom roughly 250 pixels sit under the UI. |
| Reel | 1080 x 1920 | 9:16 | The right edge carries the action buttons and the bottom carries the caption, so keep the subject centered. |
| Reel cover | 1080 x 1920 | 9:16 | The grid shows a 3:4 center crop of the cover, so design for the middle. |
Instagram Profile Picture Size
| Format | Size (px) | Ratio | Notes |
|---|---|---|---|
| Profile picture | 320 x 320 | 1:1 | Displays as a small circle, about 110 pixels on phones. Center the subject. |

Instagram image size FAQ
What is the best Instagram post size in 2026?
1080 x 1440 pixels at 3:4. Instagram moved the profile grid to a 3:4 preview and now accepts 3:4 uploads natively, so this size shows uncropped in the feed and the grid. 1080 x 1350 at 4:5 still works but gets slightly trimmed in the grid.
Did Instagram change the grid to 3:4?
Yes. The profile grid previews every post at a 3:4 portrait crop instead of the old square. Square posts still upload fine, but the grid cuts their left and right edges, so faces and text near the sides can get lost.
What size should Instagram carousel slides be?
1080 x 1350 at 4:5 is the recommended size. Every slide in one carousel must share the same ratio, and the first slide you add sets it for the rest.
