The page number of the first chapter in a book typically starts on page 1. However, the actual layout may vary depending on the book's design. In many novels and nonfiction books, introductory material, such as prefaces or acknowledgments, occupies the preceding pages, which are often numbered in Roman numerals. This formatting allows the first chapter to begin on a fresh page, emphasizing its significance. Some books may deviate from this norm for stylistic reasons or to suit specific publishing formats, but the beginning of the first chapter generally remains on page 1 or at the beginning of the following section.
