The book spine refers to the space between the front cover and the back cover. It is recommended that your page count is more than 48 pages to ensure a better-looking book spine. However, if your page count is limited to 28 or 32 pages, you can improve the book spine by choosing 200gsm matte or gloss art paper for your interior pages. Ideally, the book spine must have a thickness of about 3mm in order to be visually appealing.
The book spine normally includes the book’s title, author’s name, and publisher’s name. This is important for when readers are looking for a particular title in a row of books. If the book spine is too small it is better to leave in the blank with no information.
The book spine for perfect binding and hardcover binding will have certain differences. The thickness of a perfect-bound book spine just depends on the book’s interior. The thickness of a hardcover bound book spine will also depend on the two sheets of boards as well as the book’s interior.
