What it is

What is an Instagram grid layout?

A grid layout splits one photo across several posts, so your profile shows one big picture. It is also called a puzzle feed or a grid banner, and it works because the profile shows posts three across.

Instagram shows profile posts as 3:4 tiles, so a grid maker has to cut for that crop, not for the post size. Most grid makers still cut squares, which leave gaps and broken edges on today's grid. This one cuts for the 3:4 grid.

Ideas

Instagram grid layout ideas

Grids work best for moments you want people to notice when they land on your profile.

Brand launch
One 3×3 picture announces a new name, logo or look. People who visit your profile see the whole thing at once.
Product reveal
Split a hero shot of a new product across 6 or 9 posts. Each post works on its own in the feed and joins up on the profile.
Seasonal grid
Refresh the top of your profile for a sale, a holiday or a new collection with a 3×1 banner row.
Puzzle feed
Keep building one long picture row by row, so every new set of three posts continues the one before.
Event countdown
Post one tile a day before a launch or event. The picture completes on the day itself.

Sizes

Instagram grid sizes

Every post uploads at 4:5 (1080 × 1350). The profile grid shows its 3:4 centre, 1012.5 × 1350, so about 34 px of each side only shows in the feed.

Grid	Post size	Grid shows	Ideal photo	Posts
3×3Best	1080 × 1350	3:4 centre	3105 × 4050	9
3×2	1080 × 1350	3:4 centre	3105 × 2700	6
3×1	1080 × 1350	3:4 centre	3105 × 1350	3
3×4	1080 × 1350	3:4 centre	3105 × 5400	12

1080 × 1440 is the grid tile you see, not a size you can upload. Instagram does not accept 3:4 uploads, so a 1080 × 1440 file gets cropped back to 4:5. Upload 1080 × 1350 and let the grid trim the sides.

In the feed, people see the whole 4:5 post. On your profile they see the 3:4 centre. That is why this grid maker takes the side margins from your photo instead of padding them, so each post looks complete in the feed and joins up on the grid.

Good to know

Why your grid looks cut off

In 2025 Instagram changed the profile grid from square tiles to taller 3:4 tiles. Grids cut as squares or plain 4:5 lose their edges now, and the picture breaks at every seam.

Instagram still uploads posts at 4:5, but the grid shows a 3:4 crop, about 34 px off each side. This grid maker builds that crop into every post, so neighbouring posts overlap by exactly the hidden strip and the image joins up on your profile. Keep faces and text away from tile edges, where the gaps fall.

Posting order

Post in reverse order

Instagram shows the newest post first, at the top left. So the grid builds from the bottom right: post tile 1 first and the last tile last, a few minutes apart. The files are named in that order, grid-01 first. Pinned posts sit in front of everything and shift the grid, so unpin them or pin a full row of three.

Post 1 first, 9 last

Sharpness

Why grid posts look blurry, and how to fix it

Start wide enough
A 3-column grid needs a photo at least 3105 px wide, and 4050 px tall for 3×3. Smaller photos get upscaled and look soft.
Export at 1080 px
Posts export as high-quality JPG at exactly 1080 × 1350, so Instagram does not resize them again.
Upload over Wi-Fi
On mobile data, Instagram can upload a lower quality version. Turn on high-quality uploads in the app settings.

Some grid makers add white padding to make their posts fit 4:5. This one takes the side margins from your photo, so the feed view looks complete too.

FAQ

Frequently Asked Questions

Drop a photo, choose 3×1, 3×2 or 3×3 and download the posts. Post them in number order, starting with grid-01, and your profile shows one big picture.

Upload each post at 1080 × 1350 (4:5). The profile grid shows its 3:4 centre, 1012.5 × 1350, so about 34 px of each side is only visible in the feed.

In reverse. Post tile 1, the bottom-right tile, first and the top-left tile last. Instagram puts the newest post at the top left, so the picture builds up from the bottom right.

Both, in different places. Posts upload at 4:5, up to 1080 × 1350. The profile grid shows them as 3:4 tiles. Instagram does not accept 3:4 uploads, so never export 1080 × 1440.

Yes, each new post shifts every tile one place. Post in sets of three to keep the rows intact, or plan the next set as part of the picture.

A puzzle feed is a profile where posts join up into larger pictures. Each post still works on its own in the feed, and together they form one image on your profile.

No. The grid maker runs in your browser. Your photo never leaves your device, and there is no signup and no watermark.
