By default the gutter margin will be set to 0.
Each of those margins has a particular job.
When you re looking at a book page spread you ll have two gutters together doubling the apparent space.
This could cause issues further on as the gutter margin is the amount of space between the content of your book and the fold where the pages of the book will be bound together.
Keep that in mind when laying out your book page.
The outside margins give room for the reader s thumbs when they hold the book.
Gutter margin margins are the blank spaces around the type area on a book page but the inside margin has the special name gutter and it is always the margin on the bound edge of the book page.

Imagine a novel with text disappearing into the binding.
This process will cause a curve of the pages coming from the spine when the book is open.
