A novel format can have many format ^^
One page can have 200 words, 300... Or 500. It's depend of the font size and the page size.
On average it's 220 words per page I think, and in a other post I have calculate that FSN have 820595 words.
It's maybe not accurate, but if we use those numbers, we have 820600/220 = 3730 pages. Looks good ^^
