How to Use the Instagram Image Sizes
- Pick the Instagram format you're posting (post, story or reel).
- Copy the recommended pixel size.
- Optionally upload your photo and select that size.
- Download it cropped perfectly for Instagram.
Instagram's key image sizes
Instagram is portrait-first. Use 1080 by 1080 for a classic square feed post, or 1080 by 1350 (a 4:5 portrait) to take up the most vertical space and stop the scroll. Landscape posts are 1080 by 566.
Stories and Reels use a full-screen 1080 by 1920 (9:16) frame, and your profile photo displays at 320 by 320. Starting from these exact sizes keeps everything crisp.
Getting sharp, well-framed posts
Always upload at the recommended size and at high quality, since Instagram compresses every upload and will not add detail to a small image. Portrait formats generally earn more screen space and reach than landscape.
Keep text and key elements away from the very edges, and in Stories away from the top and bottom where the profile bar, caption and buttons sit. Use the resizer here to crop your photo to the right ratio before posting.
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.
