FAQ
How many tokens are on one page?
About 650 tokens for a standard text page (~500 words). Dense pages with small type can reach ~800; sparse pages drop toward ~400.
How many tokens is a 300-page book?
Roughly 195,000 tokens of plain text — about 150,000 words. That fits inside a 200K context window with a little room to spare.
Do PDFs cost more tokens than plain text?
They can. Some PDF workflows process both extracted text and page images; others use only text. There is no fixed token cost per PDF page or universal multiplier. Use text extraction for text-only tasks, and check image costs when layout, charts, or scanned pages matter.
How many pages fit in a 128K context window?
About 195 pages of text (128,000 ÷ 650), minus whatever you reserve for the model's answer.
Does formatting change the tokens per page?
Yes. Tables, code blocks, footnotes, and heavy punctuation all tokenize less efficiently than plain paragraphs, pushing a page above the 650 average.
