Primary Audience and Reading Age

The Primary Audience field is where you specify whether your book is intended for adults only and enter a reading age range.

Adult only content Books that contain language, situations, or images inappropriate for children under 18 years of age, such as sexually explicit content, must be marked Yes for Adult only content. Selecting Yes will automatically set your Reading Age to 18+.

Reading Age Reading age is a field you can select to specify the youngest and oldest age at which a reader might enjoy your book. While the field is optional, if you don’t include reading age for your Children’s book, it will not appear in search results on Amazon.

Reading age appears on your book’s Amazon detail page below the description. If you select a reading age of 3-5 years, it appears as “Reading age: 3-5 years, from publishers”. Please note: the reading age on your Amazon detail page may differ from your original age selection. When customers review your book, they can provide feedback on reading age and difficulty. Amazon research shows that customers are more likely to trust reading ages recommended by other customers, so Amazon updates the reading age on your book’s detail page based on reviews. For example, your book may show “Reading age: 3-5 years, from customers”. This feature improves the customer experience and ensures your book appears for appropriate ages. If your book has a customer recommended reading age on Amazon, you will not be able to update it through KDP.

Best Practice:Limit your ranges to a span of 3-4 years. Below are recommended ages by book type:

Age / Book type

Suitable books (recommended)

Age 0-2

Simple picture books with few or no words

Age 3-5

Picture books

Age 6-8

Early-level readers, first chapter books

Age 9-12

Middle-grade chapter books

Age 13-17

Teen and young adult chapter books

To update the age and grade range:
  1. Go to your KDP Bookshelf.
  2. Find the Kindle eBook you’d like to update.
  3. Click the ellipsis button (“…”) and select Edit Details.
  4. Scroll to the Primary Audience section and select the appropriate age range from the drop down menus.
  5. Click Save and Continue until you reach the Pricing page.
  6. At the bottom of the Pricing page, click Publish.

Updates may take up to 48 hours to reflect on Amazon.

Note: setting your reading age to 18+ is not the same as identifying your book as adult-only content.
