Instagram Reel Video Size and Dimension Guide
Instagram Reels have exploded in popularity, becoming a cornerstone for creators, brands, and influencers to engage audiences. But success with Reels isn’t just about compelling content — it hinges on ensuring your video matches Instagram’s official guidelines for size, resolution, and aspect ratio. In this detailed guide, you’ll learn the best Instagram reel video size specifications, plus tips for cropping, optimizing, and uploading Reels that look sharp and rank well.

Understanding Instagram Reel Dimensions
The recommended dimensions for Instagram Reels are:
- Resolution: 1080 x 1920 pixels
- Aspect Ratio: 9:16 (vertical orientation)
This aspect ratio ensures your video fills the mobile screen elegantly, without cropping important parts. Any mismatch between your video size and these dimensions can result in black bars or awkwardly cropped visuals, which can harm viewer engagement.

Why Aspect Ratio Matters for Visibility and Engagement
The 9:16 ratio is essential because:
- Full-Screen Immersion: Maximizes screen space on smartphones for a more immersive experience.
- Better Storytelling: Prevents cut-offs of captions or text overlays.
- Algorithm Priority: Instagram’s algorithm favors content optimized for its native formats.
- Higher Retention: Perfectly sized videos tend to keep viewers engaged longer.
Uploading a correctly sized clip eliminates unnecessary processing or cropping by Instagram, resulting in a cleaner, sharper playback.

Recommended File Size for Smooth Uploads
Instagram supports videos up to 4 GB, but larger files slow down uploads and processing.
For optimal performance:
- Keep your Reel under 100 MB where possible.
- Save in MP4 format for widest compatibility.
- Use the H.264 codec with AAC audio for best results.

Best Practices for Resolution and Quality Settings
To deliver crisp, professional-looking Reels:
- Stick with 1080p resolution (1080 x 1920).
- Aim for a bitrate around 8 Mbps for HD vertical video.
- Maintain 30 fps or 60 fps depending on motion requirements.
- Avoid excessive compression to prevent pixelation.

Differences Between Reels, Stories, and Feed Video Sizes
While Instagram Reels, Stories, and feed videos sometimes share dimensions, each format has distinct requirements.
| Format | Resolution | Aspect Ratio | Max Length |
|---|---|---|---|
| Reels | 1080x1920 px | 9:16 | Up to 90 seconds |
| Stories | 1080x1920 px | 9:16 | 15 seconds per story |
| Feed Videos | 1080x1350 px (portrait) / 1080x1080 px (square) | 4:5 or 1:1 | Up to 60 minutes (IGTV) |

How Video Size Impacts Reach and Algorithm Performance
