Every size, in full
The tool exports these exact pixel sizes, and compresses a file only when the network has a size limit.
| Size | Pixels | Shape | File |
|---|---|---|---|
| Instagram 3:4 postThe Instagram app accepts 3:4, but its publishing API does not, so scheduling tools need 4:5 instead. | 1080 × 1440 | 3:4 | JPEG, under 8 MB |
| Instagram portrait postThe tallest feed shape Instagram accepts from scheduling tools, and the one that fills the most screen. | 1080 × 1350 | 4:5 | JPEG, under 8 MB |
How it works

Post in number order
Download the numbered tiles and post number one first. It is the bottom right tile, because the newest post sits top left.
How the Instagram profile grid splits a picture
Your profile shows posts three across, newest first, starting at the top left. Since January 2025 each slot is a 3:4 rectangle, not a square. A grid image is one picture cut into tiles and posted one by one, so together they rebuild the picture on your profile.
If you post from the Instagram app, use 3:4 tiles at 1080 by 1440 pixels. Each post fills its slot exactly and the picture lines up with nothing lost. The catch is that Instagram’s publishing API does not accept 3:4, so scheduling tools, Posty included, cannot publish those tiles.
For scheduling, use 4:5 tiles at 1080 by 1350 pixels. The grid shows only the centred 3:4 of each 4:5 post and trims a strip from each side. The tool allows for that: each tile is cut a little wider than its slot, reaching into its neighbours, so the parts the grid shows meet exactly. Open a single post and you see those extra strips at its edges, which is expected.
Post in reverse, in number order, with nothing in between. The first tile you publish ends up bottom right once the rest are in. Check your pinned posts too: they sit at the start of the grid and push everything along, so unpin them while the grid is up or pin a full row of three.
Questions
- How do I split a picture into a grid for Instagram?
- Upload the image, choose how many rows of three and which tile type, and download the numbered tiles. Post them one after another in number order, starting with tile one.
- What order do I post grid tiles in?
- Tiles post in reverse. The newest post always takes the top left slot, so tile one is the bottom right piece and the last tile you post is the top left. Post them together, with nothing else in between.
- Should I use 3:4 or 4:5 tiles?
- Post from the Instagram app? Use 3:4 tiles, which fill each grid slot exactly. Scheduling? Use 4:5 tiles, because the publishing API rejects 3:4; the tool widens each one so the part the grid shows still lines up.
- Why do my Instagram grid tiles not line up?
- Usually one of three things: tiles cut as squares for the old grid, 4:5 tiles that do not allow for the 3:4 crop, or another post or a pinned post landing between them. Cut them here for the grid you post to, and post them together.
- Will followers see the tiles in their feed?
- Yes. Each tile is a normal post, so followers see them one at a time in their feed, where a single tile can look like a fragment. Post the set in one sitting so the full picture comes together quickly.
- Is my image uploaded anywhere?
- No. Your image opens in your browser and is processed on your own device; it is never sent to Posty or anyone else. Saving a download re-encodes the image, which also strips the EXIF data your camera stored, including GPS location. You do not need an account.
