Instagram shows posts at 1080 pixels wide. Photos can be anywhere from a wide 1.91:1 to a tall 4:5. Anything wider or taller is cropped by the app, and anything wider than 1080 px is scaled down and re-compressed. Uploading at exactly the right size means you choose the crop and you keep the sharpest result.
| Post type | Size (px) | Shape | Notes |
|---|---|---|---|
| Square | 1080 × 1080 | 1:1 | Classic, works for anything |
| Portrait | 1080 × 1350 | 4:5 | Biggest in the feed, best for people |
| Landscape | 1080 × 566 | 1.91:1 | Smallest in the feed |
| Profile grid preview | 3:4 crop | 3:4 | The profile grid shows posts as tall rectangles, so keep the subject centred |
How to do it here
- IG Post 1080×1080 is already selected in the Socials deck. For portrait, tap IG Portrait 1080×1350 instead.
- Drop your photo and drag the bright box to frame it. The darker area is what gets cut off.
- Hit Repixel it ✨, download, and post. The badge confirms exactly 1080 px wide.
Tips for sharper Instagram posts
- Start from the original photo. A screenshot or a WhatsApp copy is already smaller and blurrier.
- Portrait beats square for faces, outfits and food: it fills more of the screen as people scroll.
- Keep text away from the edges. The profile grid crops posts to 3:4, so text near the left and right edges of a square post can be cut off in the grid.
- iPhone HEIC photos upload fine to Instagram, but if you edit them on a computer first, convert with HEIC to JPG.
- Don’t over-compress. Instagram compresses again on upload. Save at the normal quality here; there’s no need for a tiny file.
Carousels
Every slide in a carousel takes the shape of the first image. Decide on square or portrait, then resize all your photos to the same preset. With many photos, Bulk resize does them all in one go and gives you a ZIP. For Stories and Reels, use the Instagram Story size page, which is 1080 × 1920.
Why exactly 1080 px?
Instagram stores and shows feed photos at 1080 px wide. A larger photo gets resized by the app with its own settings, and a smaller one is stretched up and looks soft. Uploading exactly 1080 px wide means Instagram has nothing to resize, so you keep control of sharpness and framing.
FAQ fr
What is the best Instagram post size?
1080×1350 (4:5 portrait) takes the most space in the feed. 1080×1080 (square) is the classic and the safest for any photo.
Why does Instagram crop my photo?
Instagram only accepts shapes between 1.91:1 (wide) and 4:5 (tall). Anything outside that range gets cropped automatically, often in the wrong place.
Does Instagram reduce photo quality?
Instagram resizes anything wider than 1080 px and re-compresses every upload. Starting at exactly 1080 px wide avoids an extra resize, which keeps it sharper.
What size is an Instagram carousel?
All slides use the shape of the first one, so make every image 1080×1080 or every image 1080×1350.
