# All About KDP Book Sizes Books come in all shapes and sizes. Paperback and hardcover novels and biographies are typically quite similar in size, whereas a coffee table book or a children’s book are often much larger.

Choosing a book size is more than an aesthetic decision, it can directly impact the reading experience. For example: a novel will typically be a size that is potable for a read on the go while a textbook or workbook would often need more room for text, images, graphics, and such. A small paperback coffee table book is not nearly as appealing as a large format hardcover book with large color pictures. Next time you pick up a book, you’ll have an idea that its size wasn’t chosen at random. Each book size is often carefully selected to suit its content and enhance your reading experience!
