Frequently Asked Questions

1. Why should I use a script timer? Can't I just record and see how long it is?

Timing your script isn't just about knowing how long you'll talk — it's about making your content more effective. A well-timed script helps you to match your video length to what works best for your niche, avoid rambling, and keep viewers engaged and increase average view duration.

2. How can this tool help me improve my YouTube video's retention rate?

Viewer retention is critical to YouTube's algorithm. One important milestone is the 0:30 mark — if people leave before then, YouTube is less likely to promote your video.

With the Script Timer, you can paste in your intro and see if your hook lands within 30 seconds. Then tighten your content and make sure key info or your value promise comes early, so viewers stick around.

3. How can I use YouTube Analytics with this tool?

Check these stats in your YouTube Studio:

  • Average View Duration: See how long viewers stay before dropping off.
  • Average % Viewed: Tells you if people watch most of your video or bail early.
  • Audience Retention Graph: Spot exact timestamps where drop-offs happen.

Then, test your script with the Script Timer: If people drop before the halfway mark, maybe your script is too long, and if the hook is too late, restructure so the value comes earlier.

4. How is the video duration calculated?

The calculation is based on a straightforward formula: your script's total word count divided by a specific speaking pace, measured in Words Per Minute (WPM).

Speaking pace is simply how many words a person naturally speaks in one minute. You can select from common averages like Slow (135 WPM), Standard (150 WPM), or Fast (165 WPM), enter a custom pace, or calculate your personal reading speed.

5. Is my script safe? Do you store what I paste here?

Your privacy is our top priority. The entire calculation process happens directly in your browser. We do not store, record, or see your script at any time. What you paste here stays securely on your device and disappears when you close the page. Feel free to use the tool with complete peace of mind.
