YouTube Shorts timer everything you need to know in 2025

YouTube Shorts now supports videos up to 3 minutes (180 seconds), up from the previous 60-second limit. However, longer doesn't always mean better the algorithm still favors videos with high audience retention, which typically means shorter clips.

Best YouTube Shorts length by content type

  • 15–30 seconds — Hooks, reactions, memes, satisfying clips. Highest loop rate.
  • 30–60 seconds — Tips, tutorials, product showcases. Best balance of retention and value.
  • 60–90 seconds — Mini-tutorials, storytelling, before/after. Good for educational content.
  • 90s–3 minutes — In-depth explainers, vlogs, mini-docs. Use only if the full time is necessary.

How to use the YouTube Shorts timer in the app

When recording in the YouTube app, tap the timer icon to set a countdown before recording starts. You can also set a clip duration so recording stops automatically. For best results, plan your script to fit within 30–45 seconds and record in one take.

How many Shorts can you make from a 1-hour video?

A 60-minute video contains 3,600 seconds of content. At 30 seconds per clip, that's up to 120 Shorts. At 60 seconds per clip, that's 60 Shorts. Tools like ShortPurify automatically identify the best moments so you don't have to watch the whole video manually.
