Instagram Reel Video Dimensions
The standard Instagram Reel size is 1080 × 1920 pixels at a 9:16 aspect ratio. This fills the entire mobile display edge-to-edge. You can upload at lower resolutions, but Instagram upscales them and quality suffers — always export at 1080 × 1920 or higher.
What happens with other ratios
- 16:9 (landscape): Instagram adds large black bars above and below. Avoid.
- 1:1 (square): Black bars on top and bottom — wastes screen space.
- 4:5 (portrait): Smaller bars. Better than square but still not ideal.
Reel Cover Image Size
The cover image uses the same 1080 × 1920 px canvas at 9:16, but displays at different crops depending on location:
| Display Location | Visible Area | Aspect Ratio |
|---|---|---|
| Reels tab | Full 1080 × 1920 | 9:16 |
| Profile grid | Center 1080 × 1080 | 1:1 |
| Feed preview | Center 1080 × 1350 | 4:5 |
Place your main subject and any text in the center 1080 × 1080 area so nothing important is cut off on your profile grid. Use our Instagram Photo Resizer to get cover images to the exact dimensions.
Instagram Reel Safe Zones
Instagram overlays UI elements on top of your Reel. Place text or important visuals outside these areas:
- Top 210 px: status bar and back button
- Bottom 290 px: caption text, like/comment/share buttons, audio info
- Right edge (60 px): action buttons
Keep all critical content within a 1080 × 1420 px box centered vertically on the canvas — roughly 250 px clear at the top and 250 px at the bottom.
Format & Codec Specifications
- File format: MP4 (recommended) or MOV
- Video codec: H.264
- Audio codec: AAC, 48 kHz, 128 kbps stereo minimum
- Frame rate: 30 fps recommended (24/60 fps also work)
- Bitrate: 3,500 kbps minimum for 1080p, up to 10,000 kbps
- Max file size: 4 GB
- Min resolution: 720 px wide
Duration Options
| Duration | Best For |
|---|---|
| 15 sec | Quick tips, reactions, trending audio |
| 30 sec | Tutorials, before/after reveals |
| 60 sec | In-depth how-tos, storytelling |
| 90 sec | Detailed walkthroughs, longer narratives |
Shorter Reels (15–30 sec) tend to get more replays, which boosts the algorithm signal. Longer Reels work well for educational content where watch time matters.
Tips for Maximum Reel Quality
- Export at 1080 × 1920 minimum — Instagram downscales but upscales poorly
- Use H.264 codec to avoid double compression (Instagram re-encodes to H.264)
- Keep text in the center 1080 × 1420 safe zone
- Upload over Wi-Fi — mobile uploads get extra compression
- Don't re-upload downloaded Reels — each cycle adds compression artifacts
- Light shots well — Instagram's encoder is harsher on dark/noisy footage
- Design covers separately — don't rely on a random video frame
Frequently Asked Questions
What are the exact dimensions for an Instagram Reel?
The exact Instagram Reel dimensions are 1080 × 1920 pixels with a 9:16 aspect ratio. This is the standard full-screen vertical video format used across Reels, TikTok, and YouTube Shorts.
What aspect ratio should I use for Instagram Reels?
Use a 9:16 aspect ratio for Instagram Reels. This is the only ratio that fills the entire screen without black bars. Other ratios like 1:1 or 16:9 work but Instagram adds padding around them, reducing your visual impact.
What is the Instagram Reel cover image size?
The Reel cover image size is 1080 × 1920 pixels (9:16). The cover gets cropped to 1:1 on your profile grid, so place key elements in the center 1080 × 1080 area.
What is the maximum file size for an Instagram Reel?
The maximum file size for an Instagram Reel is 4 GB. For smooth uploads, keep files under 500 MB and use H.264 video codec with AAC audio at 48 kHz.
What is the maximum length for an Instagram Reel?
The maximum Instagram Reel length is 90 seconds. You can choose from 15, 30, 60, or 90 second durations. Shorter Reels (15–30 seconds) tend to perform better for engagement.
Why does my Reel look blurry after uploading?
Blurry Reels are usually caused by uploading below 1080 × 1920, using a non-H.264 codec, or uploading over mobile data. Export at 1080 × 1920, use H.264 at 5,000 kbps or higher, and upload over Wi-Fi.
Can I upload a horizontal video as a Reel?
You can, but Instagram adds black bars above and below to fit the 9:16 frame, wasting more than half the screen. Always convert horizontal footage to vertical (1080 × 1920) before uploading.
Where is the safe zone on an Instagram Reel?
The safe zone is approximately 1080 × 1420 pixels, centered on the 1080 × 1920 canvas. Avoid placing important content in the top 210 px (status bar), bottom 290 px (caption and action buttons), and right 60 px (action buttons).
