The weight of a book depends on how large the book is. A standard paperback novel is about 6 by 9 inches. Assuming a length of 300 pages, that equates to about 15.6 ounces on average.

A standard size hardcover book weighs more than paperback. A 460-page book is about 1 pound, 2 ounces on average, while a 735-page book averages about 1 pound, 15 ounces. Textbooks, on the other hand, have larger dimensions and are even heavier. With a size of 7 by 10 inches, a 500-page hardcover book weighs approximately 2 pounds, 10 ounces. A 1000-page textbook is around 5 pounds, 3.1 ounces.
