Instagram's 3:4 Profile Grid: What Changed and How to Crop

The profile grid uses tall rectangles, not squares. Kapwing's guide says the grid changed from 1:1 to 3:4, and Planoly, last updated on 31 October 2025, gives the tile as 3:4 at 1013 by 1350 pixels. A 1080 by 1440 tile has the same shape, so the ratio matters more than the exact pixel count. Kapwing also states that users can no longer switch the grid back to squares. None of the sources checked report Instagram changing the shape again since early 2025.

One gap should be stated plainly. The Instagram Help Centre pages checked for this guide do not give the grid tile ratio. The 3:4 figure comes from the two guides above, while the news reports only say rectangles. Instagram's 2015 launch post for portrait and landscape formats says posts appear in the grid as a center-cropped square. That described the old grid and no longer applies.

Instagram's Help Centre article on image resolution currently says that a photo between 320 and 1,080 pixels wide keeps its original resolution when its aspect ratio is between 1.91:1 and 3:4. For a 1,080 pixel width, that means a height between 566 and 1,440 pixels. Anything outside the range is cropped to fit, and the app works at up to 1,080 pixels wide, so upload at least that width. Wider files are sized down.

Sources disagree on the portrait limit. Kapwing lists feed posts as 1.91:1 to 4:5, and Planoly recommends 4:5 photos to reduce cropping. Instagram's own page, checked on 13 October 2026, says 3:4. When a guide and the Help Centre differ, plan for the Help Centre and confirm in the app. Carousels allow up to 20 photos and videos, and the orientation you pick applies to every item in the post. Reels accept 1.91:1 to 9:16.

Whatever you upload, the grid thumbnail is a centre crop to 3:4, according to Kapwing and Planoly. Opening the post still shows the full image. Business Today reports that Instagram adjusts posts automatically and lets you change the result: open the post, tap the three dots, choose Adjust Preview, then pick Fit or Fill. Planoly adds that you can zoom, crop, or fit the image with borders.

The arithmetic is easy to check. A 3:4 tile cut from a 1080 by 1350 (4:5) photo is 1012.5 pixels wide, so about 34 pixels are lost on each side. A 1080 by 1080 square loses 135 pixels on each side, a quarter of its width in total. A 1.91:1 landscape of 1080 by 566 shows only about 39 percent of its width in the tile.

A grid split only lines up if every piece lands in a tile at its own proportions. Each tile is 3:4, so a 3 by 3 block is also 3:4 overall. A source image of 3240 by 4320 pixels cuts into nine tiles of 1080 by 1440. A single row of three tiles is 9:4, for example 3240 by 1440. Because 3:4 sits at the edge of the range the Help Centre lists, those pieces should not need a second crop. Old splits made of square pieces will be trimmed at the sides in the new grid, which breaks the join.

Tilo Grid, a free Instagram toolkit that ARTH makes, has a grid tool that splits one photo across layouts from 2x1 to 5x5. Its page says the web tools run in the browser with nothing uploaded, and that sharing straight to Instagram needs the Android app. The page does not mention 3:4 or any aspect ratio, so prepare the source image to the right proportions before you split it.

Take a 4:5 portrait photo at 1080 by 1350. The tile shows the central 1013 pixel column, so keep faces, logos and text inside roughly the middle 940 pixels. That leaves about 37 pixels of breathing room on each side inside the tile. If the subject sits off centre, open Adjust Preview and drag the frame, or choose Fit if cropping would cut something important.

Checklist: 1) Export at least 1,080 pixels wide. 2) Keep the ratio between 1.91:1 and 3:4 unless you have confirmed 4:5 in your own app. 3) Place key content in the middle 75 percent of the width. 4) Build splits from 3:4 tiles, not squares. 5) Check the grid preview before publishing. 6) Re-check Instagram's Help Centre every few months, as guides and rules shift.
