How to Use the Instagram Image Sizes

- Copy the recommended pixel size.
- Optionally upload your photo and select that size.
- Download it cropped perfectly for Instagram.
Instagram image best practices for reach
- Post at 1080×1350 (4:5 portrait) to take up the most space in the feed and stop the scroll.
- For stories and reels, keep text and key elements in the centre — the top and bottom are covered by the profile, caption and buttons.
- Upload the highest quality you can; Instagram compresses uploads, so start from a sharp, correctly-sized image.
- Keep a consistent visual style so your profile grid looks cohesive.
- Follow Instagram's Community Guidelines and only use content you own or are licensed to use.
Frequently Asked Questions
What is the best size for an Instagram post?
1080×1080 pixels (1:1 square) is the classic feed size. For more screen space, use a 1080×1350 portrait (4:5), which takes up the most vertical room in the feed.
What size are Instagram Stories and Reels?
Both use a 1080×1920 pixel vertical frame (9:16). Keep text and key elements away from the top and bottom, where the interface overlaps the image.
Does Instagram compress my images?
Yes, Instagram re-compresses uploads. Starting from the correct dimensions at good quality gives the sharpest final result.
