Quick Scoop: To post a Reel on Facebook, open the Facebook app, tap the Reel/Create option, choose or record a vertical video, add your caption and settings, then tap Share/Publish. Reels can be posted from a personal profile or a Page, and they work best in a vertical 9:16 format.

How to do it

  1. Open Facebook and go to the place where you normally create a post.
  2. Tap Reel or Create Reel.
  3. Add a video from your camera roll or record a new one.
  4. Edit the clip if needed, then tap Next.
  5. Add a description, thumbnail, audience, tags, and any other options you want.
  6. Tap Share or Publish to post it.

Handy tips

  • Use a vertical video in 9:16 so it displays correctly.
  • If you’re posting from a Facebook Page, the Reel option may also appear in Meta Business Suite or the Page’s content tools.
  • You can often add captions, tags, topics, and a thumbnail before publishing.
