Instagram crops photos that do not match its aspect ratios. This tool lets you post the whole picture: fit it into a 4:5, 3:4, square or Story frame with a blurred or plain background, or crop it exactly the way you want.
How to Resize an Image for Instagram
- Upload a photo or graphic above.
- Pick the platform and format from the list. The exact pixel size is shown next to it.
- Choose Crop to fill the frame (drag and zoom to choose what stays), or Fit to keep the whole image on a blurred or coloured background.
- Click Download to save a JPG (or PNG) at exactly the right size.
Instagram Sizes in 2026
| Format | Size (px) | Ratio | Notes |
|---|---|---|---|
| Tall portrait post | 1080 × 1440 | 3:4 | Shows uncropped in the feed and in the 3:4 profile grid |
| Portrait post | 1080 × 1350 | 4:5 | The long-standing standard; the grid trims a thin strip top and bottom |
| Square post | 1080 × 1080 | 1:1 | Classic look; shown with side margins in the 3:4 grid |
| Landscape post | 1080 × 566 | 1.91:1 | Takes the least space in the feed |
| Story / Reel | 1080 × 1920 | 9:16 | Keep text away from the top and bottom ~250 px |
Post the Whole Photo Without Cropping
Landscape photos and panoramas look small or get cut on Instagram. Select Fit, choose 3:4 or 4:5, and pick a blurred or white background. The full photo stays visible and the post still fills the screen.
For carousels, use the same size for every slide. Instagram uses the first slide's ratio for the whole carousel.
Crop or Fit?
Crop fills the whole frame and cuts off whatever does not fit. It is best for photos where the subject sits in the middle. Fit keeps the entire image visible and fills the empty space with a blurred copy of the photo or a solid colour. Use it for screenshots, artwork, text graphics and panoramas you do not want to cut.
Frequently Asked Questions
What size should an Instagram post be?
1080 × 1350 px (4:5) is the most common portrait size. 1080 × 1440 px (3:4) also displays without cropping in the profile grid, which switched to 3:4 thumbnails in 2025. Square posts are 1080 × 1080 px.
How do I post a full photo on Instagram without cropping?
Use Fit mode with the 4:5 or 3:4 preset. Your whole photo is placed inside the frame on a blurred or coloured background, so Instagram has nothing to crop.
What size is an Instagram Story?
1080 × 1920 px with a 9:16 ratio. Keep text and faces away from the top and bottom edges, where the interface overlaps.
Why does Instagram make my photos blurry?
Instagram scales images to 1080 px wide and re-compresses them. Uploading exactly 1080 px wide gives the app the least work and the sharpest result.
Are my photos uploaded?
No. Resizing happens entirely in your browser, so your images are never uploaded anywhere.
