Instagram Reels have become the platform's most important content format for reach and discovery. Whether you're a creator, marketer, or business, using the correct Reels dimensions ensures your videos look professional and perform better.
This guide covers everything you need to know about Instagram Reels dimensions in 2026.
Recommended Instagram Reels Dimensions

|---|---|
| Resolution | 1080 x 1920 pixels |
| Aspect Ratio | 9:16 |
| File Format | MP4 |

Why 9:16?
Instagram Reels are designed for full-screen vertical viewing. The 9:16 ratio fills the entire mobile screen, maximizing engagement and immersion.
Reels Cover Photo Size
When you upload a Reel, Instagram lets you choose a cover image. For best results:
- Recommended size: 1080 x 1920 pixels
- Visible on profile grid: 1080 x 1080 pixels (center crop)
- Best practice: Place the main subject or title in the center so it looks good in both the Reels feed and the profile grid
Common Reels Dimension Mistakes
1. Horizontal Video
Landscape videos (16:9) get cropped or displayed with large black bars in Reels. Always use vertical 9:16.
2. Low Resolution
Videos below 1080p look blurry, especially on newer smartphones. Export at 1080 x 1920 minimum.
3. Ignoring the Safe Zone
Text and important visuals near the edges may be cut off. Keep key elements centered.
4. Wrong Frame Rate
While Instagram accepts various frame rates, 30 fps provides the best balance of quality and file size.
