What is a book dust jacket?
A dust jacket is a lightweight, removable paper cover for a hardcover book. It includes a front cover, back cover, spine, and two folded flaps. These flaps fold around the book’s cover to keep the jacket in place. The dust jacket protects the book from dirt and damage. It also improves the book’s appearance and helps maintain its condition over time.
We print dust jackets for hardcover books only. For paperback dust jackets, contact our team to request a custom quote.
What should a dust jacket design include?
| Feature | Description |
| Front Cover | The front cover should show the book title, the author's name and eye-catching graphics. |
| Spine |
The spine features the book title, author’s name, and graphics, similar to those on the front cover. When placed upright, the spine faces outward. You may add a logo or edition number if a book is part of a series.
|
| Back Cover | The back cover should include a brief description of the book’s content, called a blurb, along with graphics. If you plan to sell your book in a physical store, add barcodes. You may also add a QR code. |
| Front and Back Folded Flaps | These flaps offer space to include extra information about the book. You can add promotional details like website addresses, social media handles, highlighted reviews, and publisher information. |
How do I calculate the dimensions of a dust jacket?
Start with your book’s final inner page dimensions, then add the following:
- 7mm to both the front and back cover widths (to account for the cover board wrap and hinge allowance).
- 6mm to the front and back cover heights to account for the board overhang.
- Add the spine width (same as the book’s spine).
- Add the flap width to the left and right sides: 60mm folded flaps for books with a width under 200mm. 80mm folded flaps for flaps 200 mm or wider.
- Add a 3mm bleed to all outer edges (top, bottom, left, right).
Final dust jacket size formula (with bleed):
Width = (Left folded flap) + (Back cover width + wrap) + Spine width + (Front cover width + wrap) + (Right folded flap) + bleed
Height = Trim height + 6mm (3mm board overhang and 3mm bleed top and bottom)
