In What Order Do You Post an Instagram Grid?
Bottom-right tile first, top-left tile last. Why a grid mural assembles in reverse, the exact posting order for a 3x3, and how long the alignment actually lasts.
Bottom-right tile first, top-left tile last. Instagram puts your newest post in the top-left of your profile grid and pushes everything already there one place along, so a mural assembles in reverse.
Post the tiles in reading order and the finished picture comes out rotated 180 degrees. That's the one mistake worth avoiding here, and you can't fix it without deleting posts.
Our free Instagram grid maker cuts an image into square tiles and names them in posting order, so post-01.png is the bottom-right tile and you work upwards. PXT Creator Studio is a vertical carousel editor and doesn't make grid murals, so this is a separate tool.
The order, written out
For a three-by-three grid, here's the finished mural with each cell showing the order you post it in:
| Left | Middle | Right |
|---|---|---|
| 9 | 8 | 7 |
| 6 | 5 | 4 |
| 3 | 2 | 1 |
Post 1 first, post 9 last. Work bottom row to top, right to left along each row.
Post the whole set in one sitting
Every post you make shifts every tile one place along. Upload three tiles today and three tomorrow, and anything you post in between — a Reel, a photo, anything at all — lands in the top-left and breaks the alignment.
Get the full mural up in one go, or accept that it's misaligned until the set is finished.
A mural is temporary
The alignment holds only until your next ordinary post. That post shifts every tile, and the picture starts sliding out of frame one place at a time until it's gone.
Worth knowing before you spend nine posts on one. A mural is a moment on your profile, not a permanent header — if you post daily, it lasts a day.
Three across, and you choose the rows
The profile grid is three columns wide and that's fixed. Rows are up to you. Three rows is nine posts and one full screen of profile, which is the usual choice. Two rows is six posts and finishes faster. Past three rows, the top of the picture sits below the fold where nobody scrolls.
Crop before you cut
Tiles are square, so a three-by-three grid needs a square source and a three-by-two grid needs a 3:2 one. Anything else gets trimmed from the centre, taking equal amounts off the two long edges. Picking a row count closer to your image's own shape throws away less of it.
