After all the hard work that you’ve put into the design of your perfect bound book or hard cover book, it would be a giant disappointment if you receive the printed product with text and other content lost in the binding! This disappointment could have all been prevented if only you were warned about the gutter margin.
So what is a gutter margin?
A gutter is the section of the page that leads into the binding of perfect bound books and hard cover books. These two products have binding types that are clamped and held together with glue. This process will cause a “curve” of the pages coming from the spine when the book is open.
Note: Other forms of binding, such as saddle-stitched booklets, wire-o booklets, and spiral bound booklets, do not require any gutter. These products “lay flat” and no content is lost in the “curve” of the page.
If content, such as important images and text, is too close to the spine, this content can be lost or hidden due to the curve of the pages.
To fix this problem, we always recommend proper gutter margins. A properly designed gutter margin reduces the risk of losing content in the curve of the pages.
So, what size should my gutter margin be? A gutter margin can smaller for books with less curve, and larger for books with more curve. Generally speaking, 0.5 inches for your gutter margin is recommended for most books.
What do I do if I have content, such as images or text, that goes across two pages?
Content that goes across two pages are known as “spreads”. “Spreads” can be very difficult to design for when producing perfect bound books or hard cover books due to the gutter. If spreads are very important to the overall look and feel of your book, we recommend binding types that “lay flat”, such as saddle stitched booklets, spiral bound booklets, or wire-o booklets.
Now that you understand what the gutter margin is, you can take the proper steps to prevent this potential issue. Whether it’s choosing to a flat laying binding style, such as saddle stitch booklets, wire-o booklets, or spiral bound booklet, or including the gutter margin when you start designing your perfect bound book or hard cover book.
