Instagram Image Sizes (2026 practical guide)
Instagram still serves posts at roughly 1080px on the long edge for many feed formats. Uploading a 4000px phone photo just wastes bandwidth and can look soft after platform recompression. Resize first with this free resize image for Instagram tool — defaults to 1080×1080.
Common Instagram dimensions
| Format | Pixels | Ratio | How to set |
|---|---|---|---|
| Feed square | 1080 × 1080 | 1:1 | Default on this page |
| Feed portrait | 1080 × 1350 | 4:5 | Width 1080, Height 1350 |
| Feed landscape | 1080 × 566 | 1.91:1 | Width 1080, Height 566 |
| Story / Reels | 1080 × 1920 | 9:16 | Width 1080, Height 1920 |
Workflow that looks sharp on IG
1. Resize to the target Instagram size above.
2. Compress lightly with Image Compress (quality ~80–85) so IG’s own compression is less harsh.
3. Prefer JPG for photos; use PNG only for text-heavy graphics.
4. Export once — avoid re-uploading the same file repeatedly.

FAQ
What size is best for Instagram feed posts?
1080×1080 (1:1) is the classic square. Portrait 1080×1350 (4:5) often gets more feed height. Stories and Reels use 1080×1920 (9:16).
Does this crop or only resize?
This tool resizes to the width and height you set. For fixed Instagram ratios, uncheck Keep Aspect Ratio (default on this page when both dimensions are set) so output matches exactly.
Can I batch resize for Instagram?
Yes. Select multiple images and apply the same dimensions in one run.
Are my photos uploaded?
No. Resize runs in your browser. Files stay on your device.
