Facebook Reels Dimensions
The standard Facebook Reels size is 1080 × 1920 pixels at a 9:16 aspect ratio. This is the same canvas as Instagram Reels, TikTok, and YouTube Shorts — vertical video produced once can be cross-posted everywhere with no resizing.
Cover Image
The Reel cover image uses the same 1080 × 1920 px canvas at 9:16, but displays at different crops:
| Display Location | Visible Area | Aspect Ratio |
|---|---|---|
| Reels feed | Full 1080 × 1920 | 9:16 |
| Page profile grid | Center 1080 × 1080 | 1:1 |
| News feed share | Center 1080 × 1350 | 4:5 |
Safe Zones
- Top ~210 px: profile picture, name, more options menu
- Bottom ~290 px: caption, audio attribution, like / comment / share / save buttons
- Right edge ~60 px: action buttons
Keep all important content in the center 1080 × 1420 area.

Can I cross-post Facebook Reels to Instagram?
Yes. If your Facebook Page is linked to an Instagram Business account, Meta lets you cross-post Reels in one step. Same 1080 × 1920 dimensions work for both.
What is the safe zone on a Facebook Reel?
The safe zone is approximately 1080 × 1420 pixels, centered on the canvas. Avoid the top ~210 px (profile, name) and bottom ~290 px (caption, like / comment / share / save buttons).
Where does the Reel cover get cropped?
The cover image is 1080 × 1920 px (9:16). On your Page profile grid, it gets cropped to 1080 × 1080 px (1:1) center. Place key visuals in the center 1080 × 1080 area.
Why does my Facebook Reel look blurry?
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, and upload over Wi-Fi.
