What Are Reels? Short Vertical Video as a Discovery Format
DICTIONARY · SOCIAL

What Are Reels?

Reels are short-form vertical videos, popularised by Instagram and adopted in similar form across platforms.

In plain English

The format spread because it is what recommendation engines distribute best: short, vertical, autoplaying, and easy to judge within seconds.

What makes one work is the first two seconds. Retention decides distribution, and retention is decided almost entirely by the opening.

What to know

Short and vertical
Designed for full-screen mobile.
Distributed beyond followers
Which is why it is a discovery format.
Retention-driven
Watch time decides how far it travels.
Repurposable
Clips cut from longer recordings work well.

Why it matters

For a business with expertise to demonstrate, short video is the cheapest discovery available. One recorded session produces a month of clips if planned that way.

Common mistakes

×Slow openings that lose viewers before the point.
×No captions, losing silent viewers.
×Repurposing horizontal video without reframing.
×Judging performance on views rather than on what followed.

FAQs

How long should a Reel be?

As short as makes the point. Retention percentage matters more than length.

Do I need production quality?

No. Clarity and a strong opening matter far more.
