Instagram Image Size Guide 2025
Instagram compresses and crops uploaded images. Starting with the correct dimensions prevents blurry posts and awkward crops in the feed. This guide covers every Instagram format for 2025.
Instagram Image Size Requirements (2025)
| Format | Recommended Size | Notes |
|---|---|---|
| Square post | 1080×1080 | Most common feed format |
| Portrait post | 1080×1350 | 4:5 ratio — takes more feed space |
| Landscape post | 1080×566 | 1.91:1 ratio |
| Story / Reels cover | 1080×1920 | 9:16 vertical full-screen |
| Profile photo | 320×320 | Displayed as circle |
Primary recommendation: 1080×1080 pixels (square posts)
Key Requirements
- Square posts at 1080×1080 are the safest default for product photos.
- Use JPG for photos; PNG for graphics with text or transparency.
- Carousel posts support up to 10 images — resize all at once with batch processing.
- Keep important content centered — Instagram crops previews in grid view.
- File size limit is 30 MB per image.
