Spine Bulk Program

Welcome to our Online Spine Bulk application. Here your can calculate various dimensions of your book. You can also choose your paper cover, jacket and cloth cover diagrams based on this information.

Please enter all numeric values as decimals and not fractional values. For example, when entering a custom trim size, enter 5.5 width by 8.5 height – not 5-1/2 x 8-1/2.

Our new format is now “fax-friendly,” so you can easily send your spine bulk dimensions to yourself or your clients.

We hope you enjoy the new capabilities of this program, and if you have any suggestions or comments, feel free to email us
