Spine Width Calculator

A Spine Width Calculator is your go-to tool for precisely determining your book’s spine size by taking into account both the page count and thickness of the chosen paper stock.
This is an important detail to know as the design of your cover will depend upon it. If the spine width is not correctly accounted for, this will delay your project’s progression.

External Calculator Option

If you’re designing your cover on the go, we also offer a calculator that does not require logging in, available here. However, please note, as it is external, this tool may not be 100% compatible with our system and the final width required may differ – But, it is a great guide to get you started! We strongly recommend obtaining a print quote, which will provide the exact spine width, before finalising your cover design.
