For a tall Instagram feed photo, use 3:4 (1080 × 1440); use 9:16 for Stories and Reels. Instagram also accepts 4:5 and square feed photos. Match the canvas to the placement before you export, and check the crop in the publishing app.
Instagram image sizes and aspect ratios
| Placement | Aspect ratio | Working size | Best use |
|---|---|---|---|
| Feed portrait | 3:4 | 1080 × 1440 | Tallest supported photo ratio; matches a common phone-camera frame. |
| Feed portrait | 4:5 | 1080 × 1350 | A shorter portrait canvas when you want more room around the subject. |
| Feed square | 1:1 | 1080 × 1080 | Square compositions and graphics that also need square crops elsewhere. |
| Stories and Reels | 9:16 | 1080 × 1920 | Full-screen vertical video or story artwork. |
Instagram's photo help page currently describes an accepted range from 1.91:1 landscape through 3:4 portrait, with photos up to 1080 pixels wide kept at their original ratio. A 4:5 portrait is still supported; it is no longer the tallest feed option. Instagram's photo-resolution guidance has the current limits.
Keep a 2:3 portrait without cutting off the frame
Many cameras save vertical photos at 2:3, which is taller than Instagram's 3:4 feed limit. Scale the full image to fit inside a 3:4 canvas and fill the side margins with a plain colour or a blurred extension of the photo. That preserves the original pixels without asking Instagram to choose what gets cropped.
Leave room for interface overlays
Stories and Reels use a full-screen 9:16 canvas, but the username, caption and controls cover parts of the image. Keep titles, faces and product details away from the very top and bottom edges, then preview the export in Instagram before publishing.
For a side-by-side choice between 3:4, 4:5, 1:1 and 9:16, see the Instagram aspect-ratio comparison. To batch-pad 100+ photos at once with white margins, custom borders, and 4:5 or 1:1 presets without cropping your originals, use Batchpad.
