Instagram grid maker for the 3:4 profile grid
This Instagram grid maker cuts one image into 3 columns and 1 to 6 rows of tiles that line up into a single picture on your profile. Each tile is a 1080 × 1350 post whose middle 3:4 is the piece your profile shows, numbered in the order to post it.

Choose a picture, pick the grid, and see it laid out the way your profile shows it. Your image stays in this browser tab: nothing is uploaded.
Or drop it here. PNG, JPG or WebP. A tall, high-resolution picture works best.

How the Instagram grid maker works
Instagram's profile shows posts as 3:4 rectangles, three across, newest first. The tiles are cut for exactly that.
- 1
Choose a picture and a grid
Pick 3 × 1 for a single row up to 3 × 6 for a full-screen mural. The picture is cropped to the grid's shape; slide the crop to choose what stays.
- 2
Check it the way your profile shows it
The preview lays the tiles out three across, with the number of each one, so you see the finished grid before anything is posted.
- 3
Post in number order
Post 1 is the bottom-right tile and goes first; the top-left tile goes last, because the newest post lands top left.
Image splitter for Instagram
The splitter works on a canvas inside the page: your picture is opened by the browser, cut, and drawn into PNGs without being sent anywhere. It keeps your image's full resolution up to 1080 pixels wide per tile, the width Instagram displays.
Square mode makes 1080 × 1080 tiles for anyone who still wants the older square grid. The 3:4 mode is the one that matches the profile grid as Instagram shows it today.
Instagram grid splitter
Each tile is posted as a 4:5 image, Instagram's long-standing tall feed size, with the 3:4 cell in its middle and a thin band from the neighbouring tile on each side. The profile hides the bands, and opening the post shows a little more of the picture instead of an empty edge.
At the outer edges of the image there is no neighbour to borrow from, so the edge pixels are stretched into the band. It never shows on your profile.
- 3 × 1: a banner row, three posts.
- 3 × 2 or 3 × 3: the classic puzzle feed, six or nine posts.
- 3 × 4 to 3 × 6: a picture that fills the whole first screen of your profile.
Free Instagram grid maker
Splitting and previewing are free with no account and no daily limit, because the work happens in your browser. A free Postdom account downloads the tiles, one at a time or as a ZIP, with no watermark on your picture.
Keep the grid going after the puzzle
A split image fills a few rows. Postdom reads your website and makes slideshows and short videos for your brand every week, in the styles you choose, so the posts after the puzzle look as considered as the puzzle.
Questions about the Instagram grid maker
What size are the grid tiles?
In 3:4 mode each tile is 1080 × 1350 pixels, a 4:5 post, with the visible 3:4 piece in its middle 1012.5 pixels. In square mode each tile is 1080 × 1080.
In what order do I post the tiles?
Start with Post 1, the bottom-right tile, and finish with the top-left one. Instagram puts each new post at the top left of your profile, so the last tile you post becomes the top-left corner.
Why do my tiles look cropped on my profile?
Since Instagram's profile grid switched to 3:4, a square post loses about an eighth of its width on each side there. Use 3:4 mode so the visible part of each post is exactly its piece of the picture.
Can I post the grid as a carousel instead?
A carousel shows one slide at a time, not a grid. For a picture people swipe across, use the Instagram carousel splitter, which cuts slides that meet edge to edge.
Will a new post break my grid?
Every new post moves the whole grid along by one tile. Post in rows of three, three posts at a time, to keep the picture whole.
Do you keep a copy of my image?
No. The image is opened in your browser tab and cut there. Only if you press sign up or sign in to download does this browser keep it, on your device, so it is waiting if you come back within 30 minutes. It is deleted when you return, and it never reaches Postdom.
