What is Reels?

The short vertical video format on Instagram and Facebook.

Reels are 9:16 vertical videos and the strongest way to reach non-followers on Instagram. Instagram allows Reels up to three minutes long.

Watch time, shares and completion rate drive a Reel's success. Keep text and key elements inside the safe zone, or the app's buttons will cover them.
