How to Create a Cover PDF for your Book:
ATTENTION! Important.
Download the Paperback Cover Template
from AMAZON
and follow exactly all instructions.
1) Calculate the spine width of your book
The spine width is based on the number of pages in your book:
For black and white-interior books:
White paper: multiply page count by 0.002252
Cream paper: multiply page count by 0.0025
Example of spine width calculation for a 60-page black and white book printed on white paper: 60 x 0.002252 = 0.135"
For color-interior books:
Multiply page count by 0.002347
Example of spine width calculation for a 60-page color book: 60 x 0.002347 = 0.141"
2) Set up your document
Your cover must be a single PDF that includes the back cover, spine, and front cover as one image.
You can submit your cover on any size page as long as the printable area is:
• Measured exactly to your book's trim size, spine width, and .125" bleed
• Centered horizontally and vertically
Minimum Cover Width: Bleed + Back Cover Trim Size + Spine Width + Front Cover Trim Size + Bleed
Example calculation at 6" x 9" cover with 60 B&W pages on white paper: 0.125" + 6" + 0.135" + 6" + .125" = 12.385"
Minimum Cover Height: Bleed + Book Height Trim Size + Bleed
Example calculation: 6" x 9": 0.125" + 9" + .125" = 9.25"
3) Design your cover
Safe Zone
Text and images must be at least .125" inside the trim lines to ensure that no live elements are cut during the bookmaking process.
Title and Author Name
Your book's title must match exactly to what was entered during our title setup process. You are not required to include the title name on the front cover as long as it is written in full on the spine of your book. If your book does not meet the minimum page count of 101 for spine text, you will be required to add your bookâs title in full to your front cover page.
The author's name is required to appear in the interior of your book, either a full name or initials only. Please make sure the initials match the full name you entered during our setup process, and vice versa.
Images
Images may be CMYK or RGB color. All images should be sized at 100%, flattened to one layer and placed in your document at a minimum resolution of 300 DPI.
The spine of your book
Every book will vary slightly when bound. Allow for 0.0625" variance on either side of the fold lines for your cover. For example, if your spine width is 1", your text should be no wider than 0.875". Because of this variance, avoid hard edges or lines that end on the fold line.
For books with 130 pages or less, we strongly recommend a blank spine. Blank spines are required for books with less than 101 pages.
Barcode
When your files go through the review process, our system will place your ISBN barcode in a 2" by 1.2" white box in the lower right-hand corner of your book's back cover. Our standard trim size templates will show you exact barcode placement.
Images or text in the barcode location will be covered when the book is printed. Make sure no important elements appear where the barcode will be placed.
If you choose to provide and place your own barcode, be sure it is a high-resolution image. The barcode can be located on the back or front cover of your book, at a recommended size of 2" wide by 1.2" tall. You are welcome to add an additional UPC barcode for distribution purposes if applicable.
4) Prepare for Printing
1.The printable area of your document must be the right size, including bleed.
2.Make sure the printable area is centered within your document.
3.Make sure all live elements are inside the safe zone.
4.Export your file as a print-ready PDF. Be sure fonts are embedded.
5.The maximum accepted file size for your book cover is 40 MB.

One text-page per PDF-page; One PDF-page per page number. Your document's dimensions will be the book's final trim size, plus bleed (optional) with margins.
