What is a Facebook Reel?
Definition and key characteristics
A Facebook Reel is a short-form vertical video. It plays full screen, auto-loops, and surfaces to followers and new audiences alike. Reels live in the dedicated Reels tab and appear in the main feed.
Why Reels matter for reach and engagement
Reels reach beyond your existing followers. Meta's algorithm surfaces them to users who have never liked your Page. That makes Reels one of the most efficient organic formats for building reach without spending on ads.

Step-by-Step: How to Create a Facebook Reel
Step 1: Record or upload video
Open the Facebook app. Tap Reels at the top of your feed, then tap the camera icon. Record directly in-app or tap the gallery icon to upload a clip from your device.
Step 2: Add music and effects
Tap the Music icon to browse Meta's licensed audio library. Pick a trending track or search by name. Tap Effects to apply AR filters or visual overlays.
Step 3: Edit and preview
Trim clips with the timeline tool at the bottom. Reorder clips by dragging. Tap Preview to watch the full Reel before moving on.
Step 4: Add caption and description
Write a short caption. Include keywords your audience searches. Facebook indexes caption text, so clear language improves discovery. Keep it punchy. Two or three sentences is plenty.
Step 5: Publish to your Page or Profile
Choose whether to post to your Profile or a Page you manage. Set your audience: Public, Friends, or a custom group. Tap Share to go live.

Technical Specs for Facebook Reels
Video length and dimensions
Organic Facebook Reels run from 15 seconds to 90 seconds. The recommended resolution is 1080 x 1920 px, matching the 9:16 full-screen format Meta recommends for Reels placements.
Aspect ratio and format
Use 9:16 vertical for full-screen display. Landscape clips (16:9) will be letterboxed. Square (1:1) is accepted but not ideal for the Reels experience. Facebook accepts MP4, MOV, and WebM files.
File size and bitrate
Keep bitrate between 6 and 10 Mbps for smooth playback. Upload the highest-quality file your connection allows. Meta compresses on its end, so start with the cleanest source you have.

Best Practices for Higher-Performing Reels
Hook viewers in the first second
The first second decides whether someone scrolls past. Open with motion, a bold question, or an unexpected visual. Never start with a logo screen or a black frame.
Use trending audio and sounds
Reels using trending audio get surfaced to more users. Check the Trending section of Meta's audio library before choosing a track. Match the tempo to your edit rhythm for tighter pacing.
Keep captions and text clear
Most Reels autoplay muted. Add text overlays for key points. Use large font sizes. Keep all text out of the bottom 35% of the frame. That area is often covered by the caption and UI elements.
Call to action guidance
End with one clear next step. "Follow for more." "Comment your answer below." "Link in bio." One action per Reel. More than one splits attention and reduces response.

Frequently Asked Questions
How long can a Facebook Reel be?
Organic Facebook Reels can be between 15 seconds and 90 seconds long. Shorter Reels (under 30 seconds) tend to see higher completion rates, but the right length depends on your content.
What aspect ratio should I use for Facebook Reels?
Use 9:16 vertical at 1080 x 1920 px for full-screen display. Landscape clips will be letterboxed, which reduces the viewing area and generally hurts performance.
Can I post a Reel to both Facebook and Instagram at the same time?
Yes. Meta lets you share Reels to both Facebook and Instagram simultaneously. Doing so increases reach across both platforms without any extra editing.
Do I need a business Page to post Facebook Reels?
No. You can post Reels from a personal Profile or a Facebook Page. Business Pages get additional insights like reach and plays, which helps you track performance.
