How to Resize Images for Instagram — Complete Size Guide 2026
Posting on Instagram? Using the correct Instagram image sizes ensures your photos look crisp and aren't cropped awkwardly. Here's the complete size guide and how to resize for free.
Instagram Post Dimensions
| Format | Recommended Size | Aspect Ratio |
|---|---|---|
| Square | 1080×1080 px | 1:1 |
| Portrait | 1080×1350 px | 4:5 |
| Landscape | 1080×566 px | 1.91:1 |
Instagram displays posts at 1080px width max. Square (1:1) is the most versatile — no cropping in feed. Portrait (4:5) gives more vertical space for product shots or people.
Instagram Story Size
- 1080×1920 px — 9:16 aspect ratio
- Full-screen vertical format
Instagram Profile Picture
- 320×320 px minimum (displays at 110×110 in app)
- Use a square image; Instagram crops to circle
Instagram Reels & Video
- 1080×1920 px — Same as Stories
- 9:16 vertical format
