Disclaimer

This spine width calculation uses average bulk values. The characteristics of the paper used by different print partners may vary.

Case Wrap books mostly use pre-cut cardboard in the spine. The cardboard is therefore in a number of fixed sizes. These sizes may vary between print partners.
