Instagram Reels Size and Dimensions Guide 2024
Instagram Reels have rapidly become one of the most powerful tools for creators, brands, and influencers to grow their audiences. As short-form video continues to dominate social media platforms, knowing exactly what is Instagram Reels size in 2024 can ensure that your content looks professional, fits perfectly on mobile screens, and maximizes engagement.
This detailed guide explains the recommended Reels dimensions, file size limits, video length guidelines, and optimization tactics—so your vertical videos always look their absolute best.

Why Instagram Reels Size Matters
Video size directly impacts how Instagram displays your content, its clarity, and even engagement metrics. Since Reels are mostly viewed on mobile devices in portrait orientation, using the correct dimensions ensures:
- No important visuals are awkwardly cropped.
- Text and graphics remain sharp and easy to read.
- High video quality without pixelation.
- Better performance in the algorithm due to optimal formatting.
Incorrect sizing forces Instagram’s compression tool to resize your video, which can lead to distorted visuals and reduced audience retention.

Recommended Instagram Reels Dimensions in 2024
Instagram officially recommends uploading Reels in HD vertical format.
Current recommendation:
- Dimensions: 1080 pixels wide × 1920 pixels tall
- Aspect ratio: 9:16 (portrait mode)
| Parameter | Recommendation |
|---|---|
| Width | 1080px |
| Height | 1920px |
| Aspect Ratio | 9:16 |
Uploading larger than 1080×1920 is possible, but Instagram will downscale or crop. Lower resolutions may result in blurry playback.

Maximum and Minimum File Size Limits for Reels
Your video’s file size influences both upload speed and compression quality.
- Maximum size: Under 4GB for MP4 format.
- Minimum size: No strict minimum, but low-bitrate files can appear pixelated.
- Preferred format: MP4 (H.264 codec) with AAC audio.
Aim for a file size large enough to preserve visual detail but comfortably under the maximum for smooth uploads.

Video Length Requirements
As of 2024, Instagram Reels can be:
- Up to 90 seconds long for most users.
- Certain accounts may access extended lengths up to 10 minutes as part of new feature tests.
Shorter Reels—typically 15 to 30 seconds—tend to perform better, keeping viewer attention and increasing completion rates.

Recommended Frame Rate and Resolution
A high-quality viewing experience depends on correct frame rate and resolution.
Best practice:
- Frame rate: 30fps or 60fps
- Resolution: 1080×1920 pixels
Higher frame rates help motion appear smooth, but extremely high rates can unnecessarily increase file size.

Optimizing Vertical Content for Mobile Viewing
Since Reels are viewed on smartphones, keep these tips in mind:
- Position your subject within the central third of the frame.
- Avoid placing key visuals near the interface-covered top or bottom areas.
- Use bold, high-contrast colors for visibility.
- Prioritize clear voice and balanced audio for mobile playback.

Impact of Wrong Dimensions on Engagement
Uploading a Reel with incorrect dimensions or orientation can lead to:
- Cropped text or subjects
- Letterboxing (black sidebars)
- Reduced engagement and completion rates
- A less professional overall impression
The algorithm prefers videos that deliver seamless, full-screen experiences, so correct sizes directly boost reach.

How to Crop or Resize Videos Without Losing Quality
Resizing while retaining quality involves maintaining resolution and aspect ratio.
Steps:
- Start with a high-quality source file.
- Import into a video editing program that supports custom export settings.
- Select 9:16 aspect ratio and output at 1080×1920.
- Set export bitrate around 8–12 Mbps for 1080p video.
