Cover File Requirements

Think about your book cover as a jacket made to wrap around the pages of your book with a perfect fit. A perfect fit is based not only on the trim size of your book but also the number of pages in your interior and the weight of your interior stock.

Cover Requirements Checklist
  • Your file is saved as a PDF.
  • Your back cover, spine and front cover are included as one file.
  • Your PDF size matches your book's trim size.
  • You have thoroughly reviewed your file for errors.
  • Your background extends .125" past the trim area.
  • Your spine text is centered and has a 1/16" margin on both sides.
  • Your spine has been correctly sized using our spine width calculator (optional).
  • You used our cover template generator (optional).

Saving Your Cover File for Print

The two most common programs for preparing a book cover are Adobe InDesign and Photoshop. The file you make from this software is called a native file. Once you have finished your cover preparation in the native file, you will need to save it as a PDF (Portable Document File). A PDF will lock everything in place so no movement or changes occur when the file is sent to the printer.
