The weight of a book is determined by its size. A typical paperback novel measures around 6 by 9 inches. If the book is 300 pages long, it weighs around 15.6 ounces on average.
A hardcover book of typical size weights more than a paperback. A 460-page book weighs approximately 1 pound, 2 ounces, whereas a 735-page book weighs approximately 1 pound, 15 ounces. Textbooks, on the other hand, are significantly larger and heavier. A 500-page hardcover book measures 7 by 10 inches and weighs about 2 pounds, 10 ounces. The weight of a 1000-page textbook is around 5 pounds, 3.1 ounces.
