How the grid works
- The profile grid has three tiles to a row, and each tile is 3 wide and 4 tall. We measured this on instagram.com, where a tile was 311 × 414 pixels on a screen 1,280 pixels wide. A photo or reel fills its tile from the middle.
- Your newest post is at the top left, and older posts follow to the right and then down. A set of posts is published from the bottom right back to the top left.
- Instagram added Reorder grid in June 2026: press and hold a post on your profile to drag it into place. The order matters less, but publishing in order saves the dragging.
Which shape to choose
| Shape | Size | Where you can post it |
|---|---|---|
| 4:5 | 1,080 × 1,350 pixels | Works in the Instagram app and when scheduling |
| 3:4 | 1,080 × 1,440 pixels | Post from the Instagram app: scheduling apps can't send it |
Instagram's help says a photo keeps its original size when its shape is between 1.91:1 and 3:4, so a 3:4 post at 1,080 × 1,440 pixels is the tallest it takes. Meta's API takes images from 4:5 to 1.91:1, which is why scheduling apps top out at 4:5.
Publishing the set
- Publish post 1 first and the last post last, one after another, with nothing else in between.
- Your next post after the set pushes the picture down by one tile.
- Add alt text that describes the whole picture to each post.
To cut a wide picture into slides that swipe as one image, use the carousel splitter. For one photo in every network's size, try the image resizer. In Unisenda you schedule the posts one after another with your other content.
Questions people ask
Why are the posts listed from the bottom right?
Instagram shows your newest post at the top left of the grid. The last post you publish ends up there, so you publish the bottom right one first and the top left one last.
What shape is the Instagram profile grid now?
A tile that is 3 wide and 4 tall. Instagram's head, Adam Mosseri, said in January 2025 that it launched a new tall grid, and in May 2025 that 3:4 photos now appear as shot. Instagram's help pages don't give the tile's size, so we measured it on instagram.com.
Can I schedule the posts?
Yes, if you choose 4:5. Meta's API takes images from 4:5 to 1.91:1, so scheduling apps can't send 3:4. Choose 3:4 to post from the Instagram app, where it fills each tile.
Why do 4:5 posts have a strip at each side?
A 4:5 post is a little wider than a grid tile, so the grid cuts a thin strip off each side. Each post carries the strip it loses from its neighbour's side of the picture, so the grid still lines up. Open a post and you will see it.
Is my picture uploaded?
No. Your browser cuts the posts on your device. Nothing is sent to Unisenda, and nothing is kept once you close the page.
