AM A split grid turns one big picture into a mosaic across your Instagram profile: a product launch banner spread over six posts, a panorama of a new shop, or a collection lookbook that fills the top rows. A carousel panorama does the same thing sideways, so people swipe through one long image. Both need the pieces cut precisely, in the right size and posted in the right order. This tool does the cutting and tells you the order.
It runs in your browser: the image is split on your device and never uploaded.
How to make an Instagram grid
- Drop your image into the box or click to choose one. Use the largest version you have; a 3 row grid needs about 3240 x 4320 px to stay sharp at full size.
- Choose Profile grid, then pick the number of rows: 1 row (3 posts), 2 rows (6 posts), 3 rows (9 posts) or 4 rows (12 posts).
- Keep Tile size at 3:4, 1080 x 1440, which matches the profile grid. 4:5 and 1:1 are available but will not line up perfectly (see below).
- Drag the image in the crop area, or focus it and use the arrow keys, to choose what lands in each tile. Use Zoom (100% to 300%) to frame a detail. Dashed lines show the cuts.
- Check How it looks on your profile, a mock profile that shows each tile as a 3:4 thumbnail.
- Choose JPG (quality 92) or PNG, then click Download all (ZIP), or Save on a single tile.
- Post the tiles in number order, starting with Post 1.
The posting order, explained
Instagram shows your newest post in the top left of your profile. So the tile you post first ends up at the bottom right of the finished picture, and the last tile you post sits at the top left. The tool numbers the tiles in the order to post them and names the files the same way: yourimage-01-post-first.jpg, yourimage-02.jpg and so on.
For a 2 row grid, Post 1 is the bottom right piece, Post 3 is the bottom left, Post 4 is the top right and Post 6 is the top left. Post them one after another without anything in between, or the picture shifts by one column.
Since June 2026, Instagram lets you reorder your grid: go to your profile, press and hold a post, choose Reorder grid, then drag posts into place. That is a useful way to fix a tile posted out of order, but posting in order is still simpler.
Why 3:4 tiles (1080 x 1440)
In January 2025 Instagram changed profile grid thumbnails from squares to 3:4 rectangles, and in May 2025 it added support for posting 3:4 photos without cropping. So a 1080 x 1440 px tile is shown whole in the grid, and the pieces meet edge to edge.
| Tile size | In the feed | On the profile grid | Lines up? |
|---|---|---|---|
| 3:4, 1080 x 1440 | Shown whole | Shown whole | Yes |
| 4:5, 1080 x 1350 | Shown whole | A thin strip is trimmed from each side | Close, with small gaps in the picture |
| 1:1, 1080 x 1080 | Shown whole | The sides are trimmed to 3:4 | No, the picture will not line up |
When you pick 4:5 or 1:1 for a grid, the tool warns you under the download button, and the profile preview shows the trimmed version so you can see the effect before posting.
Plan the image before you split it
The sharpest grids start from an image made at the full size of the finished mosaic. If you design the image in Canva, Photoshop or Figma, create a custom canvas at these sizes:
| Layout | Tiles | Full image size |
|---|---|---|
| Profile grid, 1 row | 3 at 1080 x 1440 | 3240 x 1440 px |
| Profile grid, 2 rows | 6 at 1080 x 1440 | 3240 x 2880 px |
| Profile grid, 3 rows | 9 at 1080 x 1440 | 3240 x 4320 px |
| Profile grid, 4 rows | 12 at 1080 x 1440 | 3240 x 5760 px |
| Carousel, 3 slides at 4:5 | 3 at 1080 x 1350 | 3240 x 1350 px |
| Carousel, 5 slides at 4:5 | 5 at 1080 x 1350 | 5400 x 1350 px |
| Carousel, 10 slides at 4:5 | 10 at 1080 x 1350 | 10800 x 1350 px |
Add guide lines at every 1080 px across and every 1440 px down (or 1350 px for carousels) so you can see where the cuts will fall. Keep faces, product names and prices clear of those lines. An image of any other size still works; the tool scales and crops it to fill the layout, and you drag to choose the framing.
Framing with drag, zoom and the keyboard
The tool always fills the whole layout, so it starts by scaling your image just enough to cover it, centered. From there you control the framing. Drag with a mouse or finger to move the image. Zoom up to 300% to crop into a detail, such as one product from a group shot. With the crop area focused, each arrow key press moves the image by one fortieth of the visible width, which is handy for lining up a horizon or a product edge exactly with a cut. The tiles and the profile preview update as you move, so you can check every piece before downloading.
Grid or carousel?
A profile grid makes a strong impression on people who visit your profile, but each tile appears in followers' feeds as a separate, partial image, and it takes several posts. A carousel panorama is one post: it shows the whole picture to followers who swipe, and does not disturb your grid. For a big launch, many brands do both: a carousel for the feed and a split grid at the top of the profile. For everyday posting, carousels are the lower effort option.
Carousel panoramas
Choose Carousel panorama to cut a wide image into 2 to 20 side by side slides for a single carousel post. Instagram carousels allow up to 20 photos or videos, a limit raised from 10 in August 2024. The default slide size is 4:5 (1080 x 1350), the tallest shape the feed shows, and 3:4 and 1:1 are also available.
Slides are numbered in swipe order. Add them to one post in that order, Slide 1 first, and people swipe across the picture as one continuous image. A strip preview under the tool shows how the slides join.
Plan the image with the cuts in mind: avoid putting a face or a product name exactly on a cut line, and give the first slide a reason to swipe, such as a half-visible product or an arrow.
Custom splits for other uses
Custom split cuts any image into 1 to 8 rows and 1 to 8 columns. By default each tile keeps the image's own resolution; you can also set tiles to 1080 or 2000 px wide. Files are named by row and column, such as yourimage-r1-c2.jpg. Sellers use this to split a large poster into printable pages, to cut a product infographic into sections for a marketplace gallery, or to make a 2 x 2 teaser for a story.
Worked examples
A 6 post launch banner
A home goods brand has a 4000 x 3000 px landscape photo of its new collection. With 2 rows of 3:4 tiles, the combined shape is 3240 x 2880 px, close to the photo's own shape, so only a strip at the sides is trimmed. The brand drags the image so the product sits across the middle four tiles and posts the six tiles on launch morning, Post 1 to Post 6.
A 3 slide panorama of a shop front
A 6000 x 2000 px panorama split into 3 slides at 4:5 makes a combined 3240 x 1350 px strip. The tool zooms to fill that shape from the center; the owner drags the image up a little so the shop sign is not cut off, then posts the three slides in one carousel.
A 9 post portrait grid
A creator wants 3 rows from a phone photo of 3024 x 4032 px. Three rows of 3:4 tiles need a 3240 x 4320 px area, a little larger than the photo, so each tile is scaled up slightly. It will look fine in the grid, but for a sharp result when someone opens a single post, start from the highest resolution original.
Tips for grids that look good
- Each tile must work alone. People see single posts in their feed, not your grid. Make sure every piece has something interesting on it, and write a caption for each.
- Keep text large and away from cuts. Letters split across two tiles are hard to read in the feed.
- Pinned posts sit above the grid. Instagram lets you pin up to three posts to the top of your profile, and they push the rest of the grid down. Unpin them while a split grid needs to line up, or plan around them.
- Post the whole set in one session so followers do not see a half-built picture for long.
For the captions, our fancy text generator adds bold or script accents, and the engagement rate calculator tells you whether the launch posts performed. Resize other images for social with the image resizer.
Troubleshooting
The grid does not line up on my profile
Check the tile size is 3:4, that the tiles were posted in number order with nothing in between, and that no pinned post is pushing them out of line. Reorder grid can fix tiles posted out of order.
Instagram cropped my tile when posting
In the Instagram post editor, use the crop control to switch from square to the photo's original shape so the 3:4 tile is posted whole. Older app versions may not offer 3:4, so update the app first.
The tiles look blurry
The source image is too small for the number of tiles. Use fewer rows or a higher resolution image. The original size is shown next to Use another image.
Part of my picture is cut off
The tool fills the grid shape completely, so an image with a different shape is cropped. Drag to choose which part is kept, or zoom out to 100%.
I cannot find the ZIP on my iPhone
Safari saves downloads to the Files app, in the Downloads folder. Tap the ZIP to extract it, open the folder, select the tiles and use Share > Save Images to put them in Photos, where Instagram can reach them. You can also tap Save on each tile in the tool to download them one at a time.
Transparent PNG areas turned white
Tiles are placed on a white background because Instagram does not display transparency. Add your own background color to the image first if white does not suit it.
