How to Make an Instagram Grid Post That Lines Up on Your Profile

A grid post is one large picture split into several posts. On your profile they sit next to each other and form one big image. It is a simple way to make a launch, a sale or a new collection stand out. Here is how to do it so the pieces actually line up.

How the Instagram profile grid works

Your profile shows posts in rows of three, with the newest post at the top left. That means:

• A grid post is built in rows of three: 3, 6 or 9 tiles.
• The last tile you post appears first (top left), so tiles must be posted in reverse order.
• Anything you post later pushes the whole grid down and can break the picture, so post all tiles in one go.

The taller profile grid

Instagram's profile grid used to show square thumbnails. In 2025 it changed to taller, portrait-style thumbnails. This matters for grid posts:

• Square tiles are cropped at the sides in the profile view, so the joins between tiles can look off.
• Keep important things such as faces, logos and text away from the left and right edges of each tile.
• After posting, you can check and adjust how each thumbnail looks in the app, and fix small crops there.

Instagram changes these details from time to time, so check how one test post looks on your own profile before you post a full grid.

Step by step

1. Plan the design

• Decide on 3, 6 or 9 tiles. Three is easiest; nine makes the biggest impact.
• Draw a rough plan first: which part of the picture goes on which tile.
• Avoid placing a single word or face across a join between two tiles.

2. Make the design at the right size

Design the whole picture at full size, then split it, rather than stretching small images. Higher resolution means a sharper result after Instagram compresses it.

3. Split it into tiles

You can split a design by hand in a design program, but it is slow and easy to get wrong. A grid app does it in seconds and keeps every tile the exact same size. In our app Gridit, you choose the Instagram grid size, add your picture, text and shapes, see a live preview of the whole grid, and use Sequential Export to save every tile with a number in posting order.

4. Post in the right order

• Post tile number 1 first. In Gridit's Sequential Export, post01 is always the first to upload.
• Upload the tiles one after another without posting anything else in between.
• Write captions that make sense on their own. Each tile also appears alone in people's feeds.

5. Check your profile

Open your profile and look at the whole grid. If a thumbnail is cropped badly, adjust its preview in the app.

Ideas for grid posts

• Product launch: one large product photo across 3 tiles.
• Sale announcement: big bold text across 6 tiles.
• Brand refresh: a 9-tile mosaic that introduces your new colors and logo.
• Carousel teaser: a grid that matches a carousel post, so the story continues when people tap.

Common mistakes

• Posting tiles in the wrong order, so the picture is scrambled
• Text running across the join between tiles
• Low-resolution images that turn blurry after upload
• Posting a single unrelated post in the middle of the set
