About this tool
A grid post is one image sliced into equal tiles that line up into a bigger picture across your profile. This tool does the slicing: pick how many rows you want, and it cuts your image into that many rows of three equal tiles and hands back each one as a JPEG.
Instagram shows your newest post top-left, so the tiles have to be posted in reverse: the bottom-right tile goes up first and the top-left tile last. The preview here numbers every tile in reading order to make that sequence easy to follow.
When a grid post is worth doing
A grid post turns the top of your profile into one large image. It's a strong move for a specific moment — and a poor default.
Good reasons to use one
- A profile refresh or rebrand where you want visitors to see a cohesive first impression.
- A launch, announcement or milestone that deserves an oversized visual.
- An intro grid for a new account — who you are, split across the first row.
Why it's not for regular posting
- Each tile looks fragmentary in the feed, so individual reach per tile is usually lower.
- Every future post pushes the grid down and breaks the picture until you post a full new row.
- It only reads correctly from your profile, not from the feed or Explore.
Getting the source image right
Grid tiles are only as sharp as the image you feed in. Instagram displays each grid cell at roughly 1080 px wide, so aim for 1080 px per column.
| Grid | Ideal source size | Aspect ratio |
|---|---|---|
| 3 × 1 (one row) | 3240 × 1350 px | 2.4 : 1 |
| 3 × 2 | 3240 × 2700 px | 1.2 : 1 |
| 3 × 3 | 3240 × 4050 px | 0.8 : 1 |
Keep faces and key text away from the tile edges — the seams between posts cut through them. Export as JPEG for photos; the tool already outputs high-quality JPEG tiles.
Posting the tiles in the right order
Instagram puts your newest post in the top-left slot, so a grid has to be uploaded back to front.
- Post the bottom-right tile first (the highest number in the preview).
- Work backwards along each row, right to left, bottom row to top.
- Post the top-left tile last. When you're done the grid reads correctly.
- Post all tiles in one sitting, a minute or two apart, so a follower scrolling your feed doesn't catch it half-built.
- Use a scheduler if you want them to publish automatically in sequence.
Frequently asked questions
What size image should I use?
Use the largest version you have. For a 3-row grid an image around 3240 px wide (1080 per column) keeps each tile crisp. The tool crops to whole pixels, so very small source images will look soft.
Is my photo uploaded anywhere?
No. The image is loaded into a canvas in your browser and sliced locally — it never leaves your device.
Why do my tiles post out of order?
Instagram places the most recent post first (top-left). Post the tiles from the last number back to 1 and the full picture assembles correctly.
What is the best size for a 3×3 Instagram grid?
About 3240 px wide by 4050 px tall — 1080 px per column and 1350 px per row — which keeps each of the nine tiles sharp at the size Instagram displays them.
How do I post an Instagram grid so it lines up?
Upload the tiles in reverse: bottom-right first, then right to left and bottom to top, finishing with the top-left tile. Post them close together so followers don't see a half-finished grid.
Can I split an image into a 3×1 strip instead of a full grid?
Yes — set the rows to 1 and the tool cuts your image into three side-by-side tiles for a single panoramic row across your profile.
