One way is to look at the overall word count of the novel and the number of pages. Divide the total word count by the number of pages to get an approximate average. Another option is to pick, say, five to ten pages scattered throughout the book. Count the words on each of those pages carefully. Add up all those word counts and then divide by the number of pages you selected. This will give you a rough estimate of the average number of words per page. Keep in mind that pages with a lot of dialogue might have fewer words compared to pages full of descriptive text.
To estimate the average words for a page in a novel, start by choosing a representative sample of pages. This could be pages from the beginning, middle, and end of the book. Use a word - counting tool if it's an e - book or simply count by hand for a physical book. Make sure to include different types of pages, like those with mainly dialogue and those with long paragraphs of description. Once you have the word counts for your sample pages, add them up and divide by the number of sample pages. This will give you an estimate. But remember, it's just an estimate and can vary depending on the formatting and writing style of the novel.
You can randomly select a few pages from different parts of the novel. Then count the words on each page and find the average of those counts.
