What is an Instagram grid post?
An Instagram grid post is one image split into equal tiles that line up into a bigger picture across your profile. Each tile is posted separately; together they read as one image on your profile page.
This tool cuts your image into rows of three tiles. With cropping on, it trims the image so each tile is 3:4 — the shape of a profile grid tile since 2025 — and Instagram won't crop the tiles again.
What size should an Instagram grid image be?
Each Instagram grid tile shows at 3:4, so aim for 1080 × 1440 pixels per tile. Instagram moved the profile grid from squares to 3:4 tiles in January 2025.
| Grid | Ideal source size | Ratio |
|---|---|---|
| 3 × 1 | 3240 × 1440 px | 9 : 4 |
| 3 × 2 | 3240 × 2880 px | 9 : 8 |
| 3 × 3 | 3240 × 4320 px | 3 : 4 |
Keep faces and text away from the seams between tiles, where the gaps cut through them.
How to post Instagram grid tiles in the right order
To post Instagram grid tiles in the right order, upload them in reverse, because your newest post appears top-left:
- Post the bottom-right tile first — the highest number in the preview.
- Work right to left along each row, from the bottom row up.
- Post the top-left tile last.
- Post all tiles in one sitting so followers don't see a half-built grid.
When is an Instagram grid post worth it?
It depends on the moment. A grid post works for a launch, a rebrand or a profile introduction, when you want visitors to see one big image. It's a poor default: each tile looks fragmented in the feed, and every new post shifts the grid out of line.
For everyday posts, pick a format that earns reach with the Instagram post idea generator.
Instagram grid post ideas
- Launch reveal: a product photo across three tiles.
- Rebrand: the new logo and colours across a full row.
- Profile intro: who you are and what you post, across the first row.
- Event poster: date, place and headline across 3 × 2 tiles.
- Panorama: a wide landscape across one row.
Why an Instagram grid breaks over time
Every new post pushes your grid one tile along, which breaks the picture until you post a full new row. Plan follow-up posts in groups of three, or treat the grid as temporary.
Frequently asked questions
What is the best size for a 3×3 Instagram grid?
3240 × 4320 pixels — 1080 × 1440 per tile — so each of the nine tiles fills a 3:4 grid square without being cropped.
Is my photo uploaded anywhere?
No. The image is loaded into a canvas in your browser and sliced locally; it never leaves your device.
Can I split an image into a 3×1 strip?
Yes. Set the rows to 1 and the tool cuts your image into three side-by-side tiles for a single panoramic row.
Why do my tiles post out of order?
Instagram places the newest post top-left. Post the tiles from the last number back to 1 and the picture assembles correctly.
