How to Crop an Image for Instagram
For a feed photo, start at 1080 pixels wide and use 1:1 for a square or 4:5 for a taller post. Use 9:16 for full-screen Stories and Reels. Crop first, keep the subject inside a safe central area, then resize and preview before posting.

Instagram crop sizes at a glance
Use 1080 × 1080 for a square feed post, 1080 × 1350 for a 4:5 portrait post, and 1080 × 1920 for a 9:16 Story or Reel canvas. Instagram’s help page says feed photos between 320 and 1080 pixels wide can retain their original resolution when the aspect ratio is supported. A 4:5 portrait post uses more vertical feed space, while a square is easier to reuse elsewhere.
- Square feed: 1:1 — 1080 × 1080
- Portrait feed: 4:5 — 1080 × 1350
- Full-screen Story or Reel: 9:16 — 1080 × 1920
- Landscape feed: up to 1.91:1 — commonly 1080 × 566
How to crop a photo for Instagram
Open the PixelXTrim crop tool and choose the original photo. Move the crop frame until the face, product, or main action sits where you want it. Download the cropped copy, then use the resizer if you need exact pixel dimensions. Keep the original untouched so you can make a different Story or feed version later.
For a portrait, leave breathing room above heads and around products. For Stories and Reels, keep essential text and faces away from the very top and bottom because interface controls can cover those zones. For a carousel, prepare every slide at the same ratio before uploading; mixing shapes can force an unwanted crop.
How to avoid losing quality
Cropping does not invent detail. A tiny crop enlarged to 1080 pixels can look soft because too few source pixels remain. Start with the largest clean original, crop only what you need, and resize once. Avoid saving a JPEG repeatedly because each lossy export can remove more detail.
Check the downloaded file at normal phone size. Fine hair, small text, product labels, and smooth skies reveal quality problems first. If they look fuzzy, use a wider crop or return to the original and export at a higher quality.
Common mistakes to avoid
- Using one file for both a 4:5 post and a 9:16 Story without checking the crop
- Putting captions or logos against the top or bottom edge of a Story
- Stretching a photo to force the ratio instead of cropping it
- Uploading a screenshot of a photo instead of the original
- Judging sharpness only while zoomed far in
A repeatable publishing workflow
Make separate named copies such as product-feed-4x5.jpg and product-story-9x16.jpg. Preview each in the destination app before publishing. This small check catches hidden text, cropped faces, inconsistent carousel ratios, and files that were over-compressed. PixelXTrim runs the crop and resize in your browser, which is useful for personal photos or unpublished campaign artwork you do not want stored by an editing service.

Frequently asked questions
Is 1:1 or 4:5 better for Instagram?
Both work. A 4:5 image occupies more vertical feed space; a square is easier to reuse across platforms. Choose the shape that protects the subject.
Why does Instagram crop my carousel?
Instagram applies one chosen orientation to the carousel. Prepare all slides at the same ratio before uploading.
Can I use 9:16 in the feed?
Use 9:16 for Stories and Reels. A feed preview may crop or display it differently, so check the preview.
Does cropping lower resolution?
It removes pixels outside the crop. Quality drops only when the remaining area is too small and must be enlarged.
Are photos uploaded to PixelXTrim?
Supported image work happens in your browser and PixelXTrim does not store the file on its server.
