Instagram Image Size 2026: The Full Dimensions Guide
Every Instagram format's exact pixel dimensions and aspect ratios in 2026 — feed, Story, Reel, profile, and carousel — plus the size that keeps your photo sharp.
Instagram image size at a glance
| Format | Aspect ratio | Recommended size |
|---|---|---|
| Feed portrait | 4:5 | 1080 × 1350 |
| Feed square | 1:1 | 1080 × 1080 |
| Feed landscape | 1.91:1 | 1080 × 566 |
| Story / Reel | 9:16 | 1080 × 1920 |
| Profile picture | 1:1 | 320 × 320 (display) · 1080 × 1080 (upload) |
| Carousel | 4:5 to 1.91:1 | 1080 × 1350 |
Which size should you use?
For feed posts, 4:5 portrait (1080 × 1350) takes up the most screen space and tends to earn more attention than square. Use square when your composition is centered. For vertical content meant to be consumed full-screen, use Story/Reel at 9:16.
How to resize without losing quality
Don't stretch a small photo to 1080px — that blurs it. Start from the highest-resolution original you have, then fit it into the target ratio by adding borders rather than upscaling. That keeps every pixel you captured.
