Ink and paper type

You have three ink and paper options:

• Black ink and 55# (90 GSM) cream paper
• Black ink and 55# (90 GSM) white paper
• Premium color ink and 60# (100 GSM) white paper
• Standard color interior with 55# (90 GSM) white paper

Note: Cream paper is currently unavailable for Amazon.com.au.

If your paperback is printed with black ink, you can choose cream or white paper. For paperbacks with color ink, you can choose white paper, which shows a higher contrast for images and graphics. For example, you're publishing a textbook with lots of images, tables, and charts. White paper will make these visual elements more striking.

When choosing your ink and paper type:

• Choose color ink if any images in your paperback are supposed to print in color. You can choose between premium color and standard color. For more information, visit Color Ink Options.
• Set up a separate paperback on your KDP Bookshelf if you have a black-and-white and color version of your book.
• Remember that the cost for paperbacks printed in color is higher. Paper type doesn't affect printing costs.

Environmental consciousness is important to us. As a manufacture-on-demand company, we produce units as they're ordered, which reduces excess production. We also maintain a commitment to recycling waste materials resulting from the printing process and from daily office operations, and we will continue to review our practices to ensure we are doing our part to protect the environment.

Trim size

You can choose from a variety of trim sizes (see the table below for a list of common trim sizes, as well as minimum and maximum page count by size). The most common trim size for paperbacks in the U.S. is 6" x 9" (15.24 x 22.86 cm). When setting up your book, this is the default in the "Print Options" section of the Paperback Content tab. If you want a different trim size, click Select a different size and choose from standard and non-standard trim sizes. You can also enter your own custom trim size. Width must be within 4"-8.5" (10.16-21.59 cm). Height must be within 6"-11.69" (15.24-29.69 cm).

If you want to enable Expanded Distribution for your book (this can help you reach more readers through bookstores, online retailers, libraries, and academic institutions), it has to meet our Expanded Distribution trim size eligibility requirements.

Note: All specifications below are shown width by height.

Bleed

Bleed is a printing term that refers to when printed items on a page, such as images or illustrations, reach all the way to the edge of the page. All book covers on KDP require bleed. However, you can choose whether your interior has bleed or not.

When to choose bleed for your interior

You should choose Bleed in Print Options if you have any images or illustrations in your book that you want to reach the edge of the page. Even if just one page in your interior requires bleed, then you need to choose the bleed option in Print Options. Remember, you will need to format your paperback manuscript file correctly to prevent a white border from appearing at the edge of the page when the book is trimmed. Learn how to format your manuscript with bleed.

Once you have set up your manuscript file with the correct bleed settings, set your interior to bleed when you choose your print options during your paperback content setup. Note that bleed is only supported for fixed-format files like print-ready PDFs. Changing the bleed settings won't change the printing cost.

Bleed for your cover

For production reasons, all covers need to have bleed. All publications are trimmed 0.125” (3.2 mm) along their edges at the end of production for quality control. When calculating your cover size please take this into account. Use our helpful cover resources to create your cover. Alternatively, you can use the following formula to calculate your cover size:

1. Choose paper thickness for interior (this will affect your spine width)

Cream Paper: 0.0025“ White Paper: 0.002252“ Color Interior Type: 0.002347“

2. Calculate spine area

(Paper Thickness) x (Page Count) = Spine Width (Trim Height) + ( 2 x 0.125“ (bleed)) = Spine Height (Spine Width) - (0.0625“ (spine area margins)) = Max Size of Any Text on Spine

3. Calculate exact size of cover

(Trim width x 2) + (Spine Width) + (2 x 0.125“ (bleed area)) = Cover Width (Trim height) + (2 x 0.125“ (bleed area)) = Cover Height

Cover finish

Our covers are printed on 80# (220 GSM) white paper stock with either glossy or matte finish:

• Glossy finish is shiny. It makes black covers darker and artwork more striking. It's typical for textbooks, children's books, and nonfiction.
• Matte finish has minimal sheen and a subtle, polished look. It's typical for novels and other fiction.
