Book Cover Dimensions for Hardcovers.
Setup for book cover dimensions, for the cover wrap, in InDesign
Book cover dimensions … we are getting technical here, but find that book cover dimensions are a source of confusion. Let’s slog through it together.
Hardcover book cover dimensions may differ among printers. A measurement template to use for book cover dimensions is needed for any hardcover book. Ask for measurements, or template, from the printer that will print the books. The cover file is a separate InDesign file from the actual text pages.
Cover wrap is not the same thing as a dust jacket!
This page is about the cover wrap only. See the yellow cover wrap in the photograph to the right.
There is a cloth cover wrap and printed cover wrap. A dust jacket is a loose paper that folds around the book, and the flaps are tucked into the front and back cover of a book. We manufacture standard and French fold styles.
Hardcover books can be bound with a printed paper cover wrap, cloth, or a number of other materials. A cover wrap is the printed paper or material that is glued to the boards of a hardcover book. There is extra margin that extends beyond the cover. This margin wraps over the top, bottom, and outside edges of the book. The cover wrap then glues to the cover, and to inside front and back covers.
The endsheets, also called ends or endpapers, will glue to the inside front and back cover. The ends cover the margins.
Working with Hardcover book cover dimensions
When a hardcover book is 9″ x 11″, we are stating the dimensions of the page. The boards extend out farther than the pages. That measurement can be slightly different depending on the printer or bindery.
If a book is 9″ x 11″, the cover wrap file span the front and back cover, spine, and extra margin. The margin folds over the boards and will glue to the inside covers.
In the USA, book designers are typically working in units of inches. However, in Europe and Asia, we work with millimeters. So, here is what we need you to do. Let’s say we are still working with that 9″ x 11″ hardcover book. We will send you a template that shows the book measurements in millimeters.
Setup the document with the cover wrap measurements / template
Let’s look at these book cover dimensions. The measurements depend on the page count and thick of paper stock and boards. Let’s assume we supply a template to you for a 9″ x 11″, 196 page book. In millimeters, it will look similar to the following. Note: On the pink shaded diagram below, you will see that the book cover dimensions are not to scale. The 3 mm adds to the outside edge as if it were a bleed. It is not. Instead, it is the fold over the thickness of the boards.
Let’s translate this into an InDesign document to print
- Either right click on the rulers to change to millimeters, or go to Edit > Preferences > Units & Increments. Change the horizontal and vertical to millimeters. Click OK.
- Under File > Document Setup, set the width to 532.45 mm, and the height to 322 mm. Ignore the Bleed and Slug settings.
- Then go to Layout > Margins and Columns. The diagram should a 15 mm margin plus a 3 mm fold over on all four sides. Enter 18 mm in top, bottom, inside, and outside. Notice that the spine measurement on the diagram is 20.45 mm. In the same dialog box, set the number of columns to 2, and the gutter to 20.45 mm.
- We still need to account for the 3 mm fold cover, so we will do that with the guidelines. Just left click on the rulers to drag guidelines. They should be set to 3 mm less than the margins. That little 3 mm space is to show the top, bottom and sides of the boards. The InDesign layout will look like the following. It is to scale for this book size.
The Layout in InDesign:
The Extension of Background Art:
The background need to extend all the way to the outside margins. The cover wrap is folded over the boards and glued down.
The PDF with Printer’s Marks:
After the PDF is made, this is what the Cover Wrap PDF will look like.
The Graphics that is Glued to the Front cover, Back cover, and Spine:
The cover of the book as seen on the finished physical book, will end (fold over the board) at the pink lines. The rest of the background is folded over the boards and hidden from view.
