The Margins of a book refer to the blank spaces that surround the printed content of each page. Each page in the book will have a top margin, a bottom margin, an inner margin and an outer margin.

Also known as "white space", the margins of a book serve several important functions:

Enhances Aesthetics

Margins help center the content on the page and make it more visually appealing. They also help separate and balance the content of facing pages.

Improves Readability

the blank margins provide contrast to the printed words and images on the page. This provides a frame to the content, which helps the eyes focus better and allows for easier reading.

Allows a Place to Hold the Book Open

the margins allow a convenient place for the reader to hold the book open. Without ample margins, the hand(s) holding the book would block some of the printed content while it was being read.

Provides an Area upon which to Write

if the reader wishes to make any notes or comments in the book, the margins provide the blank space necessary to write.

Creates a Buffer Zone during the Manufacturing Process

in most cases, a book's pages are gathered and trimmed while it is being constructed. The margins act as a safety zone between the content and the edge of the page, so there is no risk of anything important being trimmed off.

Don't Skimp on the Margins-

When designing a book, it is important not to skimp on the size of the margins. Extremely narrow margins will allow you to fit more content per page, but the resulting book will not be attractive. Narrow margins also increase the risk that some of the page content may get trimmed off during the manufacturing process.

If you are producing a perfectly bound book or a hardcover book, you also want to make sure that the inner margins are not too narrow at the gutter. The gutter is the channel formed by the inner margins of two facing pages when the book is opened. You want some extra margin width at the gutter to help "push" the content out from the spine, otherwise some content may get buried too deep into the spine and be hard to read.

Similarly, if you are planning to produce a coil bound book, you'll want to make sure that the inner margins are ample enough to accommodate the holes drilled for the coil. Otherwise you risk having some of the holes bored through, or uncomfortably close to, the page content.
