A reel built for a vertical feed
Facebook Reels are full-screen vertical videos, and Meta recommends a 9:16 frame of 1080 by 1920 pixels. That is exactly the size SocialKit renders, so there is no cropping or letterboxing when you upload.
The reel is written, voiced and captioned from your own topic, so it works for a personal profile, a creator page or a small business that wants a quick, eye-catching video without editing software.
How to post a reel made with SocialKit on Facebook

Upload to Facebook
In the Facebook app, tap Create, choose Reel and pick the file. Page owners can also upload from Meta Business Suite.

Paste the caption and hashtags written for you, edit them, then publish.

Tips for Facebook reels
- Hook early. Open on the most interesting line, not an introduction.
- Keep the words on screen short and large enough to read on a phone.
- If you run a Page, tell a small story about your product, your place or your day, rather than an advert.
- Check Meta's current guidance on reel length before you upload anything long. These limits change.
- Reuse the same video on other apps. Instagram offers a share-to-Facebook option when you publish, so check your own app.
