Why most split grids stopped lining up
A split grid used to be simple: cut the picture into squares and post them. Then Instagram changed the profile grid to show every post as a tall 3:4 tile, cropped from the middle of the post. Square tiles now lose a strip down each side on the grid, so the picture no longer meets across the joins.
These tiles are cut the other way round. Each one is a 1080 × 1350 post, and its middle 3:4, the part the grid shows, is exactly the next slice of your picture. In the feed, each post shows a little extra at the sides, carried on from its neighbours.
The grid shows the middle of every post. Cut the middle to fit, and the picture lines up.
How to use it
- Choose the image. A tall picture suits 9 or 12 posts; a wide one suits a single row of 3.
- Pick how many posts. The preview shows how it will look on your profile, and how much of the picture is trimmed to fit.
- Download the tiles. They are numbered in posting order.
- Post them in order, starting with 1, with nothing else in between.
Posting nine tiles in the right order, without doing it by hand
Nine posts, in the right order, with nothing slipping in between, is exactly the kind of thing that goes wrong when it is posted by hand. With Ninecast, you put the tiles in your content calendar in Notion or Airtable, see the finished picture on a live Instagram grid beside the calendar before anything goes out, and let each tile post itself at its time, in order.
To check a single image against every Instagram crop, use the crop checker. To lay out the next few posts together, the grid planner shows your profile before you post, again without uploading anything.
Questions that follow
How do I split a photo into a grid for Instagram?
Choose the image, pick 3, 6, 9 or 12 posts, and download the tiles. Post them in the numbered order, starting with 1. Instagram puts the newest post top left, so the tiles have to go up from the bottom right for the picture to come out the right way round.
Why do other grid splitters not line up any more?
They cut squares. Instagram’s profile grid now shows every post as a tall 3:4 tile, cropped from the middle of the post, so square tiles are trimmed at the sides and the joins drift apart. These tiles are 1080 × 1350 posts whose middle 3:4 is exactly the slice of your picture the grid shows.
What order do I post the tiles in?
Post 1 first and the highest number last, with nothing in between. Post 1 is the bottom-right tile and the last one is the top-left. Each new post pushes the rest along, so by the last one the picture sits in place.
What happens when I post something after the grid?
Each new post shifts everything one place along, which breaks the picture across the rows. Post in threes afterwards, or plan the next three together, and the picture stays intact one row lower.
What size are the tiles?
1080 × 1350 pixels, the tallest a feed post can be, saved as JPG. In the feed each one shows a little extra picture at the sides; on your profile grid the tiles meet edge to edge.
Is my image uploaded anywhere?
No. The image is cut on a canvas in your browser and the tiles are made on your device. Nothing is sent to a server or stored, and there is no upload behind this page at all.
Do I need an account to use it?
No. The grid splitter is free and needs no account. Ninecast, the planner it belongs to, is separate and has its own free trial.
