KDP vs Draft2Digital vs IngramSpark: Which to Choose?

Short answer

KDP, Draft2Digital, and IngramSpark are popular self-publishing platforms. KDP is ideal for Amazon-focused authors, offering easy setup and broad reach. Draft2Digital excels in distributing e-books to multiple retailers, while IngramSpark provides extensive print distribution. Each platform has unique features, costs, and distribution benefits to consider.

What is Amazon KDP?

Amazon Kindle Direct Publishing (KDP) is a self-publishing platform that allows authors to publish e-books and paperbacks directly on Amazon. With KDP, authors can reach millions of readers worldwide and benefit from Amazon's extensive distribution network.

Key Features of KDP

  • Royalties: Authors earn up to 70% royalties on e-books and 60% on paperbacks. The 70% royalty is available for e-books priced between $2.99 and $9.99, while books priced outside this range earn 35%. For paperbacks, the 60% royalty is calculated after deducting printing costs, which can vary based on factors such as page count and ink type.
  • ISBN Options: Free ISBNs are available, or authors can use their own. Using a KDP ISBN limits the book's distribution to Amazon, while a personal ISBN allows for broader distribution.
  • Review Process: KDP review can take up to 72 hours. During this time, Amazon checks for content quality and formatting issues. It's important to ensure that your manuscript and cover meet Amazon's guidelines to avoid delays. Learn more about KDP review timelines.
  • Print On Demand: Books are printed as orders are placed, eliminating the need for inventory. This model reduces upfront costs and risks associated with unsold stock.

Step-by-Step Publishing with KDP

  1. Create an Account: Sign up for a KDP account using your Amazon login.
  2. Prepare Your Manuscript: Format your manuscript according to KDP guidelines. This includes setting proper margins, font sizes, and ensuring the file is in a supported format like DOC or PDF.

  • Pricing Errors: Double-check that your pricing is within the acceptable range for the desired royalty rate.

How Do ISBNs Work on Each Platform?
