Instagram Image Sizes 2026: The Only Cheat Sheet You Need
The exact pixel dimensions for Instagram feed posts, Reels, Stories, and profile photos — plus how to resize in one click.
Instagram image size cheat sheet
| Format | Recommended size | Aspect ratio |
|---|---|---|
| Square feed post | 1080×1080px | 1:1 |
| Portrait feed post | 1080×1350px | 4:5 |
| Landscape feed post | 1080×608px | 1.91:1 |
| Story / Reel | 1080×1920px | 9:16 |
| Profile photo | 320×320px | 1:1 |
Why the exact size matters
Upload something off-ratio and Instagram will crop it automatically — often cutting off exactly the part of the image you wanted visible. Matching the platform's native size up front means what you see when editing is what gets published.
How to resize for Instagram in one click
- Open Smart Crop.
- Upload your image.
- Select the Instagram preset that matches your post type (square, portrait, or story).
- Download the correctly sized image, cropped toward the most visually important part of the photo rather than a naive center crop.
Portrait (4:5) vs. square (1:1): which performs better?
Portrait posts take up more vertical space in the feed, which generally means more scroll-stopping visibility per post. Square remains the safest default if the same image will be reused across multiple platforms.
Frequently asked questions
Will Instagram compress my image after upload? Yes, Instagram re-compresses everything — starting from a properly-sized, reasonably compressed source file minimizes visible quality loss after their processing.
What size should my profile photo be? 320×320px, though Instagram displays it as a circle, so keep your subject centered with margin around the edges.
