Approximately how long is a 200,000 token context window in terms of readable text?
Select an answer to reveal the explanation.
Short Explanation
You're looking at roughly 150,000 words, or about 500-600 pages of a typical novel. That's enough to hold entire books, codebases, legal contracts, and more in one call.
Full Explanation
For English text, token-to-word conversion is approximately 1 token = 0.75 words, or 1 word = ~1.33 tokens. So 200,000 tokens ≈ 150,000 words. A typical novel is 70,000-100,000 words; a typical Harry Potter book is around 77,000-257,000 words. That makes the correct estimate approximately 150,000 words, or roughly 500-600 pages of a typical novel. This means Claude's 200K context can hold: the complete text of 2-3 average novels, thousands of pages of legal documents, entire codebases of medium-sized projects, or months of email threads. The about-50-pages option dramatically underestimates. The exactly-200,000-sentences option is a meaningless unit since sentence lengths vary wildly. The about-2-minutes-of-spoken-speech option is completely wrong — 2 minutes ≈ 300 words.
