How is YouTube video reading time calculated?
The average adult reads silently at approximately 200 to 250 words per minute (WPM), while skimming can reach 400 WPM. In contrast, normal conversational speech in video lectures and podcasts ranges between 130 and 160 WPM.
This means reading a video's transcript is roughly 1.5x to 2.5x faster than watching the video at standard speed, allowing researchers, students, and professionals to absorb video information in a fraction of the time.
Why track video word count?
- Content Repurposing: Check whether a 15-minute video transcript has enough substance for an 800-word newsletter or a 2,000-word in-depth guide.
- LLM Token Budgeting: 1,000 English words typically consume approximately 1,300 tokens in GPT-4 and Claude 3.5 Sonnet. Knowing the exact word count prevents unexpected context truncation.
- Research & Linguistics: Analyze speech pacing, vocabulary diversity, and syntactic complexity across creators or lectures.
