If you opened Instagram recently and your once-tidy profile suddenly looks cropped, off-centre, or like someone shuffled it — you are not imagining it, and you did nothing wrong. Instagram quietly retired the square profile grid it had used since 2010, and a lot of carefully arranged feeds broke overnight. The familiar 1:1 squares are gone, replaced by taller 3:4 rectangles, and that single change has knock-on effects for how every post you make is displayed, cropped, and discovered. The good news is the new format is easy to design for once you understand it, and Instagram has since shipped a feature that fixes the most painful side effect. This guide explains exactly what changed, why Instagram did it, what it broke, and how to plan your content so your profile looks deliberate again — not like a Reel with someone’s forehead cut off.
What actually changed
In January 2025, Instagram switched the profile grid from a 1:1 square preview to a 3:4 vertical one. For years, every post on your profile was displayed as a perfect square — 1080 by 1080 pixels — regardless of how you shot it. Now each thumbnail in your grid is a tall rectangle, roughly 1015 by 1350 pixels, showing more vertical height and less width. The grid still arranges posts in rows of three, so the overall structure is familiar, but the shape of each cell is taller than it used to be, and there is currently no setting to switch back to squares.
This matters because the grid preview and the actual feed post are now two slightly different things. Your post still appears one way in the scrolling feed and another way as a thumbnail on your profile, and the crop between those two views is no longer identical. A photo that looks perfectly framed in the feed can lose its top or bottom in the grid thumbnail if you did not plan for the taller crop. Understanding that distinction is the whole game now.
Why Instagram did it
The short version: almost nobody posts squares anymore. Instagram’s head, Adam Mosseri, explained that the overwhelming majority of content uploaded today is vertical — Reels, vertical photos, 4:5 portraits — and forcing all of it into a square thumbnail meant cropping the most interesting part out of the preview. If you have ever seen a grid full of Reel thumbnails with the subject’s forehead sliced off at the top, that was the square grid fighting vertical content and losing.
There is a competitive angle too. TikTok and YouTube Shorts are built around full-screen vertical video, and Instagram has spent the last few years reshaping itself to compete on that turf. A taller 3:4 grid sits much closer to the 9:16 shape of a Reel, so the jump from your profile to a full-screen video feels seamless rather than jarring. The grid change is one piece of a larger, deliberate shift toward a vertical-first app. Whether you love it or not, the direction is set — Instagram is not going back to squares, so the practical move is to design for the format that exists rather than the one you got used to.
What the change broke
The biggest casualty was grid art. For years, a popular technique was the profile mosaic — arranging individual posts so their thumbnails combined into one large image, a colour gradient, a checkerboard, or a panoramic banner spanning multiple cells. Those layouts were built pixel-by-pixel around the square grid, and when the cells became taller rectangles, thousands of them broke at once. Panoramas no longer lined up; gradients shifted; carefully planned feeds suddenly looked disjointed through no fault of the creator.
Ordinary posts took a hit too. Anyone who had built a consistent aesthetic around square crops found their older posts re-cropped in the new taller cells, sometimes cutting off text, logos, or faces that used to sit safely inside the square. If your profile looks slightly broken right now, this is almost certainly why — it is displaying old square-era content inside new rectangular cells. The fix is partly forward-looking (design new posts for 3:4) and partly a cleanup job on what is already there.
The numbers that matter now
Here is the practical takeaway hidden in those numbers, and it is the thing most outdated guides get wrong: the grid preview is 3:4, but the size you should actually export your posts at is 4:5 — 1080 by 1350 pixels. That single size is the safe all-purpose dimension. It looks right in the feed, where 4:5 is the recommended portrait ratio, and it sits comfortably inside the 3:4 grid cell without important elements getting cropped. If you remember only one number from this article, make it 1080 by 1350. Source: the shift and its rationale were confirmed directly by Instagram’s head Adam Mosseri.
How to plan content for the 3:4 grid
Design at 4:5, keep the centre safe
Build your posts at 1080 by 1350 pixels and treat the very top and bottom edges as a danger zone. Because the feed view and the grid thumbnail crop slightly differently, anything critical — text, faces, logos, your call to action — should sit comfortably in the central area where both views overlap. A useful habit is to imagine a margin around the inner two-thirds of your image and never place anything you cannot afford to lose outside it. This single discipline solves the majority of “why is my post cut off” problems.
Stop making new square posts
A 1:1 square still uploads fine, but it now sits awkwardly in a 3:4 cell with empty space or an unflattering crop. There is no upside to designing new squares for a profile that no longer displays them as squares. Switch your templates, your Canva presets, and your camera framing to vertical now, so that as old square posts scroll off the top of your grid, your profile steadily becomes consistent again without any cleanup.
Think in vertical, not in mosaics — for now
Elaborate multi-post mosaics are riskier in the 3:4 era because the taller cells and changing previews make precise alignment harder to guarantee across devices. That does not mean grid art is dead — a banner split across a top row of three can still work beautifully — but it does mean you should test it on a real phone before committing, and lean toward designs that tolerate small shifts rather than ones that fall apart if a single cell moves.
The June 2026 update that fixes the worst part
For most of 2025, the only way to fix a broken grid order was the dreaded delete-and-repost — taking down a post and re-uploading it just to move it, losing all its likes and comments in the process. That era is over. In June 2026, Instagram rolled out grid reorder globally: you can now drag any post to any position on your profile without deleting it, losing engagement, or reposting. Mosseri had teased the tool back in early 2025, and it finally reached everyone.
This changes grid strategy meaningfully. You can now place your strongest or most representative posts at the top to hook new visitors, group content by theme or colour, or rebuild a banner that broke during the format change — all by dragging, with nothing lost. If you have been avoiding any kind of grid curation because the old workaround was too destructive, it is worth revisiting now that reordering is free and reversible.
What this means for grid art and image splitting
If you still want a panoramic banner or a multi-tile image across your grid, the technique itself has not changed — you split one large image into equal tiles and post them so they reassemble across the cells. What has changed is the shape you design for. In the square era you split images for 1:1 cells; now you plan around the taller 3:4 preview, keeping key elements away from the cell edges where the new crop bites. A browser-based Instagram image splitter handles the cutting for you, so the only real work is choosing a source image that survives the taller crop and posting the tiles in the right order. With grid reorder now live, even a misaligned banner is fixable by dragging rather than starting over.
Frequently asked questions
Because Instagram changed it. In January 2025 the platform replaced the long-standing 1:1 square profile grid with a taller 3:4 vertical preview, so every thumbnail is now a rectangle rather than a square. You did not change a setting and nothing is broken on your end — it is a platform-wide update that applies to every profile. The change was made because most content uploaded to Instagram is now vertical, and squares were cropping the best part out of the preview.
No. There is currently no option to revert the profile grid to the old 1:1 square layout. The 3:4 format is now the default for all accounts, and Instagram has not offered a toggle to change it. The practical response is to design new content for the taller format rather than wait for a reversal that is not coming. As older square posts scroll off the top of your grid and newer vertical posts replace them, your profile will look consistent again on its own.
Use 1080 by 1350 pixels, which is the 4:5 portrait ratio. This is the safe all-purpose size: it displays correctly in the feed, where 4:5 is recommended, and it fits inside the 3:4 grid thumbnail without cropping out important elements. If you only remember one dimension, make it 1080 by 1350. Keep your key visuals — text, faces, logos — toward the centre, since the feed view and the grid thumbnail crop slightly differently from one another.
Instagram’s head, Adam Mosseri, said the change reflected how people actually use the app: the vast majority of uploads are now vertical — Reels and portrait photos — and the square grid was cropping that content awkwardly. A taller 3:4 grid shows more of each vertical image and sits closer to the full-screen shape of a Reel, creating a smoother experience. There is also a competitive motive: it aligns Instagram more closely with vertical-first platforms like TikTok and YouTube Shorts.
It can re-crop them. Posts originally designed for the 1:1 square grid now display inside taller 3:4 cells, which may cut off content that used to sit safely inside the square — text near the top, a logo at the bottom, or part of a face. The posts themselves are unchanged; only the thumbnail crop is different. If your profile looks disjointed, this is usually why. You cannot re-crop old thumbnails individually beyond the limited tools Instagram provides, so the main fix is forward-looking.
Many broke when the cells changed shape. Mosaic layouts — where multiple post thumbnails combined into one large image, a gradient, or a panoramic banner — were built precisely around square cells, so the move to 3:4 misaligned thousands of them overnight. Grid art is still possible, but it now has to be planned for the taller cell and tested on a real device before posting. The June 2026 grid reorder feature also makes rebuilding a broken banner far easier, since you can drag tiles into place rather than deleting and reposting.
Yes, as of June 2026. Instagram rolled out grid reorder globally, letting you drag any post to any position on your profile without deleting it or losing its likes and comments. This ends the old delete-and-repost workaround that used to be the only way to rearrange a feed. You can use it to put your best posts at the top, group content by theme, or repair a grid layout that the format change disrupted — all without losing engagement.
No, and the difference trips people up. 3:4 is the shape of the grid preview on your profile. 4:5 (1080 by 1350 pixels) is the recommended size to actually export and post, because it is the safe ratio for the feed. The two are close but not identical — 3:4 is slightly taller. The simplest approach is to post at 4:5 and keep important elements centred, which looks right in both the feed and the slightly taller grid cell without manual adjustment.
Reels already fit the vertical direction well, which is part of why the grid moved to 3:4 in the first place — their thumbnails now display more naturally. For carousels, lock every slide to the same aspect ratio, ideally 4:5, so the set swipes cleanly and the cover thumbnail sits correctly in the grid. The general rule across all formats is the same: design vertical, keep key elements centred, and check how the cover or first frame looks as a grid thumbnail before you post.
Putting the 3:4 grid into practice?
The tools that pair with planning your Instagram feed.
Instagram’s grid hasn’t been square since January 2025 — but most “Instagram grid” guides still tell you to design for 1:1.
The grid preview is 3:4, the safe post size is 4:5 (1080×1350), and as of June 2026 you can finally drag posts to reorder them without deleting. If your advice predates that, it’s wrong.The bottom line
The square Instagram grid is not coming back, and that is fine — once you design at 1080 by 1350, keep your key elements centred, and stop making new squares, the new format is genuinely more flattering for the vertical content most people post anyway. The format change in January 2025 caused real disruption, especially for anyone who had built grid art around squares, but the June 2026 reorder feature has removed the worst of the pain by letting you rearrange your profile freely. Treat your grid as something you curate deliberately rather than something chronology decides for you, and a profile that briefly looked broken becomes an asset again.
