How it works
How to make an Instagram grid
- 1
Upload your photo
Big, simple images with one clear subject work best. The tool center-crops it to fit the grid shape.
- 2
Choose your grid
3×1 for a single banner row, 3×2 or 3×3 for a full mosaic. The cut lines preview exactly where the tiles split.

You get numbered tiles at 1080×1080. Post the last tile first: Instagram fills your grid right to left, newest first.
What a grid mosaic is and when to use one
An Instagram grid, sometimes called a puzzle feed or mosaic, is one large image cut into square tiles and posted so it reassembles across your profile's 3-wide grid. Done well, it turns your profile page into a single billboard, which is why launches, menus, and announcements love it.
How the 3-wide grid works
Your profile shows posts in rows of three, newest first, filling from the right. A mosaic exploits that: tile 9 of a 3×3 goes up first and ends bottom-right, tile 1 goes up last and lands top-left. Each tile is still an ordinary square post, so the mosaic only assembles on your profile page, not in the feed.
The posting order, spelled out
Post the highest-numbered tile first and count down to tile 1. If you post them in reading order instead, the mosaic assembles mirrored and the effect breaks. Scheduling the set a few minutes apart keeps the order intact without you sitting there posting nine times in a row.
Mind the feed view
Every tile also appears alone in your followers' feeds, and a random ninth of a photo makes for a weak post. The trick is picking an image where each tile still looks intentional, or pairing the mosaic drop with captions that make each fragment a teaser. Grids suit moments, not everyday posting.
Tips for grids that hold up
Keep faces and text away from the cut lines, check the preview lines before downloading, and avoid tight patterns that make misalignment obvious. Remember that new posts push your mosaic down and out of alignment, so plan how long it should live at the top before regular posting resumes.
Good to know
Instagram grids, answered
Post the highest-numbered tile first and work down to tile 1. Instagram fills the profile grid right to left with the newest post, so counting down makes the mosaic assemble correctly, top-left last.
Every tile downloads at 1080 by 1080 pixels, Instagram's native square size, saved as high-quality JPG. The source photo is center-cropped to the grid shape before cutting.
A 3×1 banner row is the safest: one clean strip across the top of your profile. 3×3 makes the most spectacular billboard but posts nine feed items in a row, so save it for launches and big moments.
Each tile appears alone in the feed, so a random fragment can look odd. Choose images where every crop still reads on its own, or write captions that turn the fragments into a countdown.
No. The splitting happens entirely in your browser with the canvas API; the photo never leaves your device. That's also why it's instant.
