Free Script Timer — Calculate How Long
Your Video Will Be

How to Use This Script Timer

Using the script timer is straightforward. Paste your entire video script or outline into the text area above — this includes your intro, main talking points, transitions, and outro. The timer updates in real time as you type, so you can see your video length change instantly as you add or remove content.

Next, choose your speaking speed. Most casual YouTube content creators speak at around 120–140 words per minute (WPM). Energetic presenters, educational channels with fast delivery, and some short-form creators push to 160–190 WPM. If you've never timed yourself, try the "Normal (130 WPM)" setting as your baseline, then adjust after checking your recordings.

Finally, select your target platform — YouTube, Shorts, TikTok, or Podcast. The tool will tell you whether your script is the ideal length, too short, or too long, and give you an exact word count to add or cut. If you break your script into sections using blank lines, the breakdown panel shows you the timing for each section individually — useful for spotting which part of your video is dragging.

Why Script Length Matters for YouTube

Script length is one of the most underrated decisions a creator makes, yet it directly affects your retention rate, ad revenue, and channel growth. YouTube's algorithm rewards videos where viewers watch the majority of the content — a signal it interprets as high quality. Getting your script length right before you record means you won't have to drag out short content or desperately cut a bloated video in post.

For YouTube long-form content, the sweet spot has shifted over the years. In 2024 and beyond, videos between 8 and 15 minutes perform best for mid-roll ad revenue while maintaining strong average view durations. Videos under 5 minutes often don't qualify for mid-roll ads, cutting your earnings potential significantly. Videos over 20 minutes can work for highly engaged audiences (tutorials, documentaries, deep dives) but require exceptionally strong hooks and clear chapter structure to prevent drop-off.

For YouTube Shorts and TikTok, the math inverts entirely. Under 60 seconds is the target for Shorts — the platform is built for instant gratification and loop-friendly content. TikTok rewards completion rate above almost everything else, which means a tighter, denser 45-second video will outperform a meandering 3-minute one. The script timer helps you know exactly whether your hook + main point + CTA will fit before you even pick up the camera.

For podcasts, the ideal length depends on your format — solo shows tend to perform best at 20–35 minutes, while interview-format shows can run 45–60 minutes when the conversation is genuinely engaging. Using a script or detailed outline (even just bullet points) and timing it beforehand prevents you from wandering into territory that adds runtime without adding value.

The bottom line: knowing your video length before you record makes you a more intentional creator. You'll cut the right things at the scripting stage — where it's easy — rather than scrambling in the edit.
