Instagram Grid Crop Resize Guide (2026 Update)
Instagram grid previews now favor taller crops. Learn how to keep faces, logos, and text safe with ShareMint focal point cropping.
In 2026 Instagram's profile grid preview no longer renders as a clean 1:1 square every time. The grid can render taller previews than the feed view, which means a square 1080×1080 post that looks perfect in the feed can be cropped top-and-bottom on the grid — often slicing faces, captions, or product hotspots. The fix is to export at 4:5 (1080×1350) and anchor ShareMint's focal point on the important subject so the crop stays centered across both surfaces.
Steps
Understand taller grid previews
Instagram profile grids now favor taller previews than the old square-only grid. That means feed crops and grid crops can differ, especially for square and portrait posts.
Upload your photo to ShareMint
Open ShareMint in your browser. Drag in your original photo (HEIC from iPhone is fine, no conversion required) or paste from clipboard.
Pick the Instagram portrait preset
Select the Instagram Feed (Portrait 4:5 — 1080x1350) preset. You can also keep the Square 1:1 preset selected to export both common feed ratios.
Set a focal point on the subject
Click the most important spot in the photo (a face, a product). ShareMint anchors the crop on that point so grid and feed previews are less likely to cut off your subject.
Export and download
Hit Resize & Export. Download the portrait file individually or grab the full ZIP if you exported multiple ratios at once.

Did Instagram really move away from square-only grids?
Yes. Grid previews are no longer reliably square-only, so crops can differ between the profile grid and the full feed view.
Will my old square posts look broken?
They can look different in grid previews because a taller crop may add padding or crop edges. ShareMint can re-export older assets with a focal point so the important subject stays centered.
What portrait size should I upload?
For feed portraits, 1080x1350 (4:5) is the practical export size in ShareMint. Keep key content centered to survive grid and feed crops.
Can I batch-fix many old posts at once?
Yes. Switch ShareMint to batch mode, drop up to 50 photos, apply the Instagram portrait preset, and download everything as a single ZIP.
