If you are insisting that on average a page is 500 words or 4,000 words the equivalent of 8 pages. By simple math you saying the average book is 80,000-120,000 words, would mean on average a novel is 160-240 pages. These would be classified as short novels or more so novels for older kids or younger teens.
Page Counts. In most cases, industry standard preferred length is 250 words per page... so a 400 page novel would be at about 100,000 words. If you want to see what size book is selling in your genre, take a look on the shelves. If the average length is 300 pages, you're looking at a 75,000 word manuscript (approximately) One reason it's harder for a new author to sell a 140,000 word manuscript is the size of the book. A 500+ page book is going to take up the space of almost two, 300 page books on the shelves.
