# How Long Should YouTube Shorts Be in 2026?

The optimal length for **YouTube Shorts in 2026 is 30–45 seconds** for the highest combination of completion rate and total view-hours.

## The 5 Shorts length buckets

| Length       | Avg completion rate | Algorithm boost | Best for                 |
| ------------ | ------------------- | --------------- | ------------------------ |
| Under 15 sec | 85–95%              | Medium          | Quick hooks, memes       |
| 15–30 sec    | 72–82%              | High            | Listicles, tips          |
| 30–45 sec    | 62–72%              | Highest         | Most niches — sweet spot |
| 45–60 sec    | 50–62%              | Medium-high     | Story-driven             |
| 60+ sec      | 40–55%              | Variable        | Deep explainers — risky  |

## Why 30–45 seconds wins

1. Long enough to deliver substance
2. Short enough to maintain completion
3. High view-hours per video

## When to break the rule

* Pure meme content → under 15 seconds
* Story narration → 45–60 seconds
* Tutorial / how-to → 50–60 seconds
* Quote reels → 15–25 seconds

## Engineer the retention curve

Place a "retention beat" (visual change, payoff tease) every 7–10 seconds. The AI Reel Maker auto-paces retention beats.

## FAQ

### Should I make Shorts as long as possible (60 sec) for max watch time?

No. Completion rate matters more than absolute length.

### Are 90-second Shorts worth posting?

Risky for new channels. Stick to 30–45 seconds until 50K+ subs.
