What changes the answer
Speed and page density move it most. A dense non-fiction page can hold far more words than a page of dialogue, so treat 250 words a page as a starting point, not a fact: count one full page of your book for a precise number. If you're not sure of your speed, the reading speed test takes about two minutes.
