Each page (one sided) in novel format averages 250 words. Of course this depends on the amount of dialogue. But the average is 250. So if you're writing something on any sort of word processor and want to know how many pages as a novel it would be than go to 'tools', then 'word count'. Take the number given by the word count and pull up the 'calculator' tool, then take the number of words divided by 250, and you have your answer.
