Spine Size Guide

 

If you are setting up the design of your own cover, the table below will provide a useful guide to the width of the spine
for your book. We recommend that you supply an 'open' file, i.e. a file in the software that you designed it in, so we can do any fine adjustments to the spine size which can sometimes occur before the cover is be printed.
