Page count refers to the total number of pages in a document, book, or publication. It is an important metric used in publishing, printing, and digital media to determine the length and size of a work. Page count can influence factors such as production costs, pricing, and reader engagement. In the context of books, page count can vary widely depending on the genre and format. For example, a novel may have hundreds of pages, while a children's book might have only a few. Understanding page count helps authors, publishers, and readers gauge the scope of a written work.
