Instagram Grid Maker and Carousel Splitter

How to Use the Instagram Grid Maker

1. Pick Grid to spread one picture across your profile, or Carousel for one post that people swipe through.
2. Tap Choose a photo. Want to try it first? Tap See an example first.
3. Pick how many posts or slides you want, and their shape.
4. Drag the photo to move it. Pinch it, or use the slider, to zoom. Fit the whole photo shrinks it until all of it fits, with a color around it.
5. Check the preview. Then tap Save / Share all on a phone, or Download all (ZIP) on a computer.

No photo yet? Pick one from our free stock images. Bigger photos make sharper posts. Each piece is 1080 pixels wide, and a photo straight from a phone camera is plenty for 9 posts.

How to Post a Grid on Instagram in the Right Order

Instagram shows your newest post first, in the top-left corner of your profile. So the last piece of the picture has to go up first. The tool numbers every piece in the order to post it.

1. Save all the pieces to your phone.
2. Post number 1 first. It's the bottom-right corner of the picture.
3. Post number 2 next, then 3, and so on. Share each one as its own post, not all together as a carousel.
4. Let each post finish uploading before you start the next one, so they go up in the right order.
5. Post the biggest number last. It's the top-left corner.
6. Open your profile and check that the picture lines up.

Post from the Instagram app. For now, 3:4 posts can only be shared from the app. Scheduling apps use Meta's publishing tools, which only take shapes from 4:5 to 1.91:1.

Pinned posts. Pinned posts always sit at the start of your grid. With 1 or 2 pinned, your picture moves along by one or two spaces and breaks up. Unpin them while you post, or pin 3 so they fill the top row. Try it with the Pinned posts buttons in the preview above.

Posting more later. Every new post pushes the picture along by one space. To keep it lined up, post in sets of 3.

Fixing a mistake. Since June 2026, Instagram lets you move posts around your grid. Press and hold a post on your profile, tap Reorder grid, then drag posts where you want them. Pinned posts stay at the top. It rolled out from June 8, 2026, so update the app if you don't see it yet.

How to Post a Seamless Carousel on Instagram

A seamless carousel is one wide photo cut into slides, so the picture carries on from one slide to the next as people swipe. As of November 2026, a carousel can hold up to 20 photos and videos, according to Instagram's help page.

1. Tap Carousel in the tool above and choose your photo. It picks the number of slides that fits your photo best, and you can change it to anything from 2 to 20.
2. Save all the slides to your phone.
3. In Instagram, start a new post and tap the button to select more than one photo.
4. Tap your slides in order: 1, 2, 3 and so on.
5. If the slides look cut off, tap the crop button and pick the full shape. Instagram gives every slide in a post the same shape.
6. Add a caption and share it.

• Keep faces and words away from the lines between slides, so nothing gets cut in half.
• Slide 1 is the cover. It's what people see first in their feed, and the only slide that shows on your profile grid.
• Put a slide in the wrong place? Instagram's help page says you can tap ⋯ on the post, tap Edit, then press and hold a slide to move it.
• Make your caption stand out with Instagram fonts, and see if your carousels do better than single photos with the Instagram engagement rate calculator.

Instagram Grid and Carousel Sizes (November 2026)

Instagram keeps photos up to 1080 pixels wide, in any shape from 1.91:1 (wide) to 3:4 (tall), and crops other shapes to fit, according to its help page on photo sizes. Your profile grid then shows a 3:4 rectangle from the middle of each post:

For a grid of 3:4 posts, the whole photo is 3 posts wide:

A 9-post grid is 3:4, the same shape as a photo taken upright on most phones, so it fits with nothing cut off. For a seamless carousel, the whole photo is 1080 pixels wide for each slide: 4 slides of 3:4 make 4320 × 1440.

Need sizes for Stories, Reels or anything else? See Instagram post sizes. To check a photo's size in pixels, or turn it into a JPG, use the image file size calculator.

Why Your Instagram Grid Looks Cropped

In January 2025, Instagram changed the profile grid from squares to taller 3:4 rectangles. Square and 4:5 posts now show on your profile with a strip cut off the left and right. When someone taps the post, they still see all of it.

• Old grids made of square pieces don't line up any more, because each piece loses its edges. Make the pieces 3:4 (1080 × 1440) and nothing is cut. That's what the 3:4 setting in this Instagram grid maker does.
• A carousel only shows its first slide on your grid.
• Reels show as a 3:4 cut from the middle of the video.
• Newer versions of the app let you change which part of a post shows on your grid. Tap ⋯ on the post and look for the option to adjust its preview.

Other parts of your profile get cropped too. Highlight covers show in a small circle, so make them with the Instagram highlight cover maker, and check how your profile picture fits its circle with the Instagram PFP maker.

Grid, Carousel or Collage: Which One Do You Need?

• Grid: one picture spread over 3 to 12 separate posts, so your profile looks like one big poster. Good for launches, big news and landscapes.
• Carousel: up to 20 slides in one post. A seamless one is a panorama that people swipe through. It's a single post, so it doesn't fill up your followers' feeds.
• Collage: several photos in one picture. For a story collage, use Layout in Instagram's story camera, which fits up to 6 photos in one story.

This tool makes grids and carousels from one photo. It doesn't put several photos together into a collage.
