Book Layouts

Self-Ended Pages usually use the same type of paper for all the pages. A possible reason behind this is to be more efficient in printing books.

In contrast, Separate Ended Pages typically use a different paper type for the story pages and a different paper type for the end pages. Publishers and authors sometimes prefer Separate Ended Pages to customize the end pages to add illustrations or more information about the book or the author.

Book pages are typically printed on huge sheets of paper and then folded into individual pages. A paper sheet would produce 4 pages. Also, most of the bookbinding processes require the rule of 4. If a book is not divisible by 4, the extra pages are either left blank or will cost extra to cut off. For example, a book with a 30-page count will have print on 7.5 sheets and no print on 0.5 sheet, equivalent to 2 blank pages.
