Cropping & sizing
Why is Instagram cropping my photos? Ratios and fixes
Short answer
Instagram keeps a photo uncropped only if its shape is between 1.91:1 (landscape) and 3:4 (portrait); anything wider or taller is cropped to the nearest supported ratio. A full 9:16 phone screenshot or a panorama is always cut. Crop or pad it to 1080×1440 (3:4), 1080×1350 (4:5), 1080×1080 or 1080×566 before posting, or zoom out in the crop step to fit it inside the frame.
Key takeaways
- Instagram keeps a photo uncropped if its aspect ratio is between 1.91:1 and 3:4 (1080 × 566 to 1080 × 1440); other shapes are cropped to fit (Instagram Help).
- A 9:16 phone screenshot or story-size graphic is always cropped in the feed; a 4:3 phone photo is not.
- The profile grid shows every post as a 3:4 thumbnail, so wide posts lose their sides there even when the post itself is complete.
- In the crop screen you can move the photo and adjust how it fits in the frame before tapping Next.
- In a carousel, prepare every slide at the same size so the first slide's shape does not crop the rest.
Which photo shapes Instagram crops
| Photo shape | Example | Cropped? | Fix |
|---|---|---|---|
| 3:4 portrait | 1080 × 1440, 3024 × 4032 phone portrait | No | Post as is |
| 4:5 portrait | 1080 × 1350 | No | Post as is |
| 1:1 square | 1080 × 1080 | No | Post as is |
| 4:3 landscape | 4032 × 3024 phone photo | No | Post as is |
| 16:9 landscape | 1920 × 1080 | No | Inside 1.91:1, kept (small on screen) |
| 9:16 portrait | 1080 × 1920 screenshot | Yes, top and bottom | Pad to 3:4 or post as a Story |
| Panorama | 4000 × 1500 (2.67:1) | Yes, sides | Pad to 1.91:1 or split into a carousel |
Portrait phone photos (3:4) are now the tallest shape Instagram keeps, so a photo straight from the camera usually posts uncropped. Screenshots and designs made at story size are the ones that get cut.
How Instagram decides what to crop
Instagram's help gives the rule: photos keep their original shape between 1.91:1 and 3:4, and a photo outside that range is cropped to fit a supported ratio. In the crop screen you choose which part stays by moving the photo and adjusting how it fits inside the frame. After posting, the profile grid shows each post as a 3:4 thumbnail, so even an uncropped post can lose its sides there.
Find your case
| What you see | What it usually means | Do this |
|---|---|---|
| Tall phone photo or screenshot cut at top and bottom | 9:16 is taller than 3:4, the tallest ratio Instagram keeps | Pad or crop to 3:4 (step 2) |
| Panorama cut at both sides | Wider than 1.91:1 | Pad to 1.91:1 or split into a carousel (step 3) |
| Post is full, but the profile grid thumbnail is cut | The grid shows 3:4 thumbnails | Keep the subject in the center 3:4 area (step 4) |
| Carousel photos all cut the same way | Every item takes the shape you choose for the first | Crop all slides to one ratio (step 5) |
| Story or Reel looks zoomed | Those fill a 9:16 screen | See the Story and Reel guides (step 6) |
Fix it step by step
Check your photo's ratio
Divide width by height. Instagram keeps 1.91 (landscape) down to 0.75 (3:4 portrait). A 3024×4032 iPhone photo is exactly 3:4, so it fits; a 1170×2532 screenshot is 0.46, so it is cropped.
Fit tall images into 3:4
Add a border or background to make the canvas 1080×1440, or crop to it yourself so you decide what stays. In Instagram's crop step you can also zoom out to fit more of the photo before posting.
Fit wide images into 1.91:1
Pad a panorama to 1080×566 or cut it into 4:5 slices for a swipeable carousel. Both keep the full width visible.
Design for the 3:4 profile grid
The profile grid crops thumbnails to 3:4. A 3:4 post shows whole; for 4:5 or square posts, keep faces and text away from the very top and bottom.
Crop every carousel slide to the same ratio
In a carousel, the orientation you choose (square, portrait or landscape) applies to every photo and video, so mixed shapes are cropped to match the first. Export all slides at one size.
Stories and Reels follow different rules
They fill the phone screen at 9:16 and are covered by buttons near the edges, so the fix is a 1080×1920 canvas with a safe area.
Sizes Instagram posts without cropping
| Tallest portrait | 1080 × 1440 px · 3:4 |
|---|---|
| Classic portrait | 1080 × 1350 px · 4:5 |
| Square | 1080 × 1080 px · 1:1 |
| Widest landscape | 1080 × 566 px · 1.91:1 |
| Always cropped | 9:16 screenshots, 2:1 and wider panoramas |
Post the whole photo without cropping
- Check the shape: divide width by height. Between 0.75 and 1.91 is safe.
- For a taller image, add margins left and right until it is 3:4 (for example 1080 × 1440 with the image centered).
- For a wider image, add margins above and below until it is 1.91:1 (1080 × 566), or split a panorama into slides.
- In Instagram's crop screen, move and zoom the photo so the whole image sits inside the frame, then tap Next.
- Check the post on your profile grid: the 3:4 thumbnail can still hide the edges of square and landscape posts.
Why Instagram crops photos when you select multiple
When you select several photos for one post, they are shown as a carousel at a single shape, so photos of different shapes are cropped to match. Prepare all slides at the same size first (all 1080 × 1350, for example), and check each slide in the crop step before posting.
Stories and Reels crop differently
Stories and Reels are 9:16 and full screen. A feed-shaped photo added to a Story is either shown smaller on a background or zoomed to fill the screen if you pinch it larger. On screens taller than 9:16, Meta says vertical creative may be zoomed to fill the screen, which can crop areas outside the safe zone.

Black bars and landscape photos
A landscape photo inside Instagram's range (up to 1.91:1, 1080 × 566) is posted without cropping, but it looks small in the feed next to portrait posts. Bars inside a feed photo usually come from an editor or a screenshot, not from Instagram. For the most screen space, crop landscape shots to 4:5 when the subject allows.
Exact sizes that Instagram never crops
| Shape | Size | Use for |
|---|---|---|
| 3:4 portrait | 1080 × 1440 | Tallest feed post, matches the profile grid |
| 4:5 portrait | 1080 × 1350 | Portrait posts and carousels |
| 1:1 square | 1080 × 1080 | Square posts |
| 1.91:1 landscape | 1080 × 566 | Widest feed post |
Instagram keeps photos 320 to 1080 px wide at their original resolution inside these shapes; wider photos are scaled to 1080 px wide.

Reel covers and profile pictures
- Reel covers: Instagram's API crops a non-9:16 cover to its middle 9:16 rectangle, and to the middle 1:1 square when the Reel is shared to the feed.
- Profile grid: every thumbnail shows as 3:4.
- Profile picture: shown as a circle, so keep the face in the center.
Post a carousel with photos of different shapes
- Pick one shape for the whole carousel: 4:5 (1080 × 1350) suits most portrait and square photos.
- Pad photos that don't fit (white or blurred margins) instead of cropping into the subject.
- Export every slide at exactly the same size.
- Select the slides in order; check each one in the crop screen before posting.

How much each common photo shape loses
Instagram keeps photos between 1.91:1 and 3:4. Computed: for photos outside that range, this is the part cut away when the picture is cropped to the nearest allowed shape.
| Photo | Shape | Cropped to | Cut |
|---|---|---|---|
| iPhone portrait 3024 × 4032 | 3:4 | no crop | 0% |
| DSLR portrait 4000 × 6000 | 2:3 | 3:4 | 11% of the height |
| Phone 9:16 image 2160 × 3840 | 9:16 | 3:4 | 25% of the height |
| Screenshot 1170 × 2532 | about 1:2.16 | 3:4 | 38% of the height |
| Ultra-wide 3440 × 1440 | 2.39:1 | 1.91:1 | 20% of the width |
Pad a tall image onto a 1080 × 1440 canvas, or crop it yourself before uploading, so you choose what stays.
Pad or crop: which to pick
| Situation | Better choice | Why |
|---|---|---|
| Faces or text near the edges | Pad to 1080 × 1440 | Nothing is cut, the background fills the rest |
| Plenty of empty space at the edges | Crop to 3:4 yourself | You choose what is removed |
| Panorama wider than 1.91:1 | Crop to 1.91:1 or split into a carousel | A single wide image would be cut at both sides |
Common mix-ups
- “Instagram only allows 4:5 or square”
Its help center keeps any ratio from 1.91:1 to 3:4 uncropped, which includes 3:4 portraits straight from most phone cameras.
- “Uploading at higher resolution prevents cropping”
Cropping depends on shape, not pixels. A 4K 9:16 image is cropped exactly like a small one.
Frequently asked questions
How do I post a full picture on Instagram without cropping?
Make its shape fit 1.91:1 to 3:4: pad it with a border or background to 1080×1440 (portrait) or 1080×566 (landscape), or zoom out in Instagram's crop step.
Why does Instagram crop my vertical photos?
Phone screenshots and 9:16 images are taller than 3:4, the tallest shape Instagram keeps, so they are cut to 3:4.
What aspect ratio does Instagram use for the grid?
Profile thumbnails are shown at 3:4, so 3:4 posts appear whole and other shapes are trimmed in the grid only.
Why is Instagram cropping my photos to square?
Older app versions and some posting tools default to a square crop. In the crop screen, change the framing before tapping Next, and keep the photo between 1.91:1 and 3:4.
Why does Instagram crop my photos on my Story?
Stories are 9:16. A feed-shaped photo is shown smaller on a background or zoomed in if you pinch it to fill the screen. Use a 1080 × 1920 version for Stories.
Why is Instagram cropping my photos so much?
The photo is far outside 1.91:1 to 3:4, such as a 9:16 screenshot or a panorama, so a lot has to be cut. Add margins to reach a supported shape first.
Why is Instagram cropping my photos in a carousel?
All slides in a carousel are shown at one shape. Make every slide the same size, such as 1080 × 1350, before selecting them.
Why is Instagram cropping my photos weird?
The photo is outside 1.91:1 to 3:4, or the crop screen centered on a different part. Adjust the framing in the crop screen before tapping Next, or pad the photo to a supported shape.
How do I stop Instagram cropping photos to square?
In the crop screen, change the framing before tapping Next, and keep the photo between 1.91:1 and 3:4, such as 1080 × 1350 or 1080 × 1440.
Why is Instagram cropping my photos when I post them?
The photo is outside 1.91:1 to 3:4, or the crop screen's framing was off. Crop to 1080 × 1350 or 1080 × 1440 first, then check the framing before tapping Next.
