Your Instagram grid got taller and cropped your best photos

Open your shop's Instagram profile right now. Look at the grid, the little thumbnails under your bio.

They are not squares anymore.

Sometime in the last year Instagram stretched every one of them into a tall rectangle, and it did it to photos you had already posted. A picture that looked balanced the day you shot it is now missing a strip, or floating oddly in a taller frame than it was built for. If your grid has felt a little "off" lately and you couldn't say why, this is why.

Instagram's profile grid is now 3:4 and vertical. Any photo you post that isn't shaped for it gets cropped, and the part it crops is often the part you cared about most.

What actually changed

For more than a decade the grid was a wall of perfect squares. You composed a photo for a square, it showed up as a square. Early in 2025 that ended. The grid became a 3:4 rectangle, taller than it is wide, and it has been rolling out to every account since.

Adam Mosseri, who runs Instagram, gave the reason plainly: most people post vertical now, so the profile should show vertical. Phones are tall. Reels are tall. The grid caught up to the shape of the screen.

That is fine if you are a person posting selfies. It is a quiet headache if you run a shop, because the photos a shop posts, the storefront and the product staged on a table, were mostly framed for a square. Now they get pinched into a taller box and Instagram decides what to keep.

Why your shop photos look worse than they did

The grid keeps the center and trims the edges. Whatever sat near the top, the bottom, or the sides of your square is the first thing to go.

A record shop in Broad Ripple posted a photo of their front window with the shop name painted across the top of the glass. Lovely shot. In the new grid the name is gone, cropped off above the frame, and what's left is a window with no sign on it.

Logos go the same way. A bakery in Zionsville tucks a small watermark into the bottom corner of every photo, the way a lot of shops do. In a square it sat neatly in the corner. In the 3:4 grid the bottom gets trimmed and the watermark goes with it. They were branding every post and didn't realize the branding had stopped showing.

The feed is gentler than the grid. In the feed a photo can run up to 4:5, close to the grid shape but not the same. So a picture can look right when someone taps into it and still look wrong in the grid preview. That gap is what makes this so confusing. You check one post, it looks fine, and you never notice the grid is quietly slicing it.

What size should I post now?

One number fixes most of it: 1080 by 1440 pixels. That is the 3:4 shape the grid wants, and it is the only size that shows with no cropping at all on your profile.

If your camera gives you 4:5 (1080 by 1350), that is still good and close. It shows almost whole in the feed and loses only a sliver in the grid. What you want to stop doing is posting squares and landscapes and hoping they land. They won't.

There is a simpler habit hiding under the numbers: keep anything that matters in the middle. Your sign, your face, your logo, the words on your chalkboard, the plate of food. Put them in the center of the frame and leave room around the edges. The center survives every crop Instagram has. The edges are a gamble.

The center of the frame is the only part Instagram promises to keep. Treat the edges like they might disappear, because they might.

Can I fix the posts I already have?

Partly. Instagram started letting people reorder the grid this summer, so you can drag posts around and change which ones sit up top. That helps the overall shape of the page.

What you cannot do is un-crop an old square. The pixels the grid hides are still in the original file, but Instagram gives you no way to reclaim them on a post that is already up. If a photo's whole point was the sign across the top, the only real fix is to post it again, reshot or resized for 3:4.

So I wouldn't spend a Saturday trying to rescue two years of old posts. Do this instead: fix the shape from here on, and re-post the three or four photos that actually pull their weight, the storefront shot people screenshot, the product that sells. Those earn a reshoot for the taller frame. The rest can age out on their own.

The part that is bigger than Instagram

This goes past Instagram now. Vertical is the shape of how people meet your shop: a phone held upright, in a feed that scrolls up and down. TikTok and Reels are built on it, and even Google leans on tall images across a lot of its results now.

The square was a design decision from an earlier phone, and that era is over. If you are getting new photos taken this year, or setting up a corner to shoot your own product, build the whole thing tall. Frame a standing rectangle, not a square you will crop later. You will use those photos everywhere, and they will fit everywhere.

Your grid is often the second thing a new customer sees, right after they hear your name. It is worth ten minutes to stop it from cutting your work in half.
