Gatefolds
What are gatefolds?
Gatefold pages that are wider than a regular book page, with a vertical crease or fold roughly in the middle.
One edge is bound into the book, and the free edge can be unfolded to reveal the full width of the Gatefolds allowing you more room to display a wide photograph, schematic, family tree, or anything else that might benefit from more page area.
You can place two gatefolds facing each other for maximum width (four panels wide when unfolded).There can only be one fold per gatefold page. You can include up to four gatefold pages in a book.
The maximum page width for gatefold pages is 8.75".Gatefolds can be included as part of your contents file or sent as separate files. See our Prepare Your Files page for more information about setting up gatefold page layouts.

Maximum gatefold page size
Gatefold pages can be added to any book with page dimensions up to 8.75" wide. The bound panel of a gatefold is 0.125" narrower than the book page width, and the folded panel is 0.5" narrower than that.
See our Prepare Your Files page for guidance on how to set up gatefold pages.
How many gatefold pages can I have in my book?
You can include up to four gatefold pages in your book. They can be placed wherever you like in the book.
Some customers place two gatefold pages next to each other, to get the maximum width possible when both pages are unfolded (four panels wide).
