Paste your script below. We will calculate the word count and estimate exactly how long your final video will be (based on average speaking rates).
Slow (130 WPM)
Normal (150 WPM)
Fast (170 WPM)
Custom Speed (WPM):
For YouTubers, podcasters, and video creators, pacing is everything. Knowing exactly how long your video will be before you even hit the record button helps you structure your content, hit specific algorithmic length targets, and avoid rambling.
A normal, conversational speaking speed is around 150 words per minute. If you are recording an audiobook or a dramatic voiceover, you might aim closer to 130 WPM. For fast-paced YouTube shorts or TikToks, creators often speak at 170 WPM or faster.
After estimating your video length and recording it, you can upload the finished video to Subvideo.ai to automatically generate subtitles, translations, and burned-in captions.
Paste or type your video script into the editor area.
Look at the statistics box to see your exact word and character counts in real time.
Check the slow, normal, or fast speed boxes, or enter a custom Speaking Speed (WPM) to view the estimated video duration.
WPM stands for Words Per Minute, which is used for English and space-separated languages. CPM stands for Characters Per Minute, which is used for CJK languages (Chinese, Japanese, Korean) where words are not separated by spaces.
The average speaking speed for conversational YouTube videos is around 150 WPM. Slow-paced narrations are around 130 WPM, and energetic promos or TikToks can exceed 170 WPM.
Yes, our script timer automatically detects CJK characters and adjusts the reading speed metrics (CPM) accordingly to ensure accurate duration estimates.
No, there is no limit. You can paste scripts of any length, from short 15-second ads to hour-long podcast scripts.
