How do I count my pages in a children’s book? Same as in a regular book, all books start on the right-hand page and all books end on the left-hand page. All books are in even number of pages. Children’s books are usually 24 or 32 pages. So if you have a book, you will start with a right-hand page. Remember, in a hardcover, you are not counting the endpapers and then you will end on a left-hand page, not counting the endpapers.
