Spine Width Calculation for Soft Cover Perfect Bound Books
When designing your cover for a perfect bound soft cover book, you’ll need to know the exact spine width, which is based on the page count (total pages in document, including blank pages) and the thickness of the type of paper chosen. The spine width calculator will give you the measurement you need.
Note: Spines narrower than 0.20″ cannot have spine text printed on them. For soft cover binding, printing on 60lb paper, the page count needs to be around 100 pages or higher to have spine text.
