Case Binding Cover design
For exact cover and spine width calculations please use our Cover and spine width calculator. More
Case binding covers must be designed and supplied as per the below specifications. If you are not experienced with hard cover design, the services of an experienced graphic designer should be considered. When considering a Graphic designer, please ensure that they have had experience in Book and Cover design for print and not just E-Books.
For a case to fit your book accurately, your cover must be 8mm taller and 6mm wider than your internal text pages. On top of that you must include an additional 25mm bleed, this is called turn in. The 25mm bleed or turn in as it is often referred to, must include 15mm of the image or background colour used for your cover design. The leftover 10mm is covered by the end papers and therefore does not require any image or background colour.
Spine widths differ depending on the thickness of your book. The text stock, cover thickness and the number of pages in the book influence the thickness of your book.
Please keep in mind that the binding process can have a variance of up to 1mm, therefore, we strongly advise that your artwork is not designed to line up flush with the spine. The preferred design would be that the front, spine and back cover are a continuous image across the spread. If this is not possible, a spine colour which blends into the cover design will reduce the look of movement.
