When it comes to self-publishing, authors today have more choices than ever before. Amazon’s Kindle Direct Publishing (KDP) is often the first name that comes to mind, but other platforms like IngramSpark, Draft2Digital, Lulu, and Apple Books also offer unique advantages. If you’re trying to decide where to publish your next book, understanding the differences can save you time, money, and effort. Let’s break it all down in simple language.
What is KDP?
KDP, or Kindle Direct Publishing, is Amazon’s self-publishing platform. It allows authors to publish ebooks and paperbacks directly to Amazon’s global marketplace. One of the biggest advantages is the massive audience — Amazon reaches millions of readers worldwide.
Other Self-Publishing Platforms
There are many alternatives to KDP:
-
IngramSpark: Focuses on print-on-demand books and distribution to bookstores.
-
Draft2Digital: Specializes in ebook distribution across multiple retailers like Apple Books, Kobo, and Barnes & Noble.
-
Lulu: Known for high-quality print-on-demand options and global distribution.
-
Apple Books: Great for reaching Apple device users, though less global reach compared to Amazon.
Each platform has its strengths and weaknesses. Choosing the right one depends on your goals: do you want maximum reach, higher royalties, or professional print quality?
Royalties and Pricing
One of the first things authors care about is royalties. Here’s a quick comparison table:
| Platform | Ebook Royalty | Print Royalty | Notes |
|---|---|---|---|
| KDP | 35%-70% | 60% of list price minus printing costs | Huge audience, easier marketing on Amazon |
| IngramSpark | Varies | 45%-55% | Great for bookstore distribution |
| Draft2Digital | 60% of net | N/A | Excellent for ebook wide distribution |
| Lulu | 80% after cost | 80% after cost | High-quality print, good for photo books or art books |
| Apple Books | 70% | N/A | Only ebooks, limited to Apple users |
Notice that KDP offers a higher royalty percentage on ebooks if you price within the 70% royalty bracket, but print royalties may be lower compared to Lulu or IngramSpark because of printing costs.
Ease of Use
KDP is designed for beginners. The interface is simple, uploading a manuscript and cover is straightforward, and Amazon provides step-by-step guidance.
Platforms like IngramSpark can feel more technical. You might need to handle ISBN registration yourself, set up print specifications, and navigate distribution options. Draft2Digital, on the other hand, focuses on simplicity, especially for ebook authors. Lulu has a clean interface, but designing your print book can take more effort due to advanced customization.
Distribution Reach
Amazon’s KDP is unmatched in sheer audience size. You instantly reach millions of readers who are already browsing for books.
Other platforms offer broader retail reach but may require extra effort to get noticed. For instance, Draft2Digital pushes your ebook to multiple stores automatically. IngramSpark can get your paperback into bookstores and libraries — something KDP does not do as extensively.
Here’s a visual breakdown:
| Platform | Retail Stores | Libraries | International Reach |
|---|---|---|---|
| KDP | Amazon only | Limited | Very high |
| IngramSpark | 40,000+ | Yes | High |
| Draft2Digital | 20+ | No | Moderate |
| Lulu | Various | Limited | Moderate |
| Apple Books | Apple devices | No | Limited |
Cost to Publish
KDP has no upfront cost. You upload your book and start selling immediately. This makes it ideal for first-time authors.
Other platforms may charge setup fees:
-
IngramSpark: $49 setup for print books, plus revision fees.
-
Lulu: Free for digital, but some print options cost.
-
Draft2Digital: Free to upload, but they take a cut of sales.
Marketing Support
Amazon provides built-in marketing tools such as Kindle Unlimited, Amazon Ads, and the “Look Inside” feature. This gives authors the ability to promote directly to readers browsing on Amazon.
Other platforms often leave marketing entirely up to the author. Draft2Digital and Lulu provide some analytics and promo tools, but you will need your own email lists, social media campaigns, or ad strategies.
File Formats and Customization
KDP accepts PDF for print and MOBI or EPUB for ebooks. It has some restrictions on formatting, but it is beginner-friendly.
Platforms like IngramSpark or Lulu allow for more professional-quality prints and offer hardcover options, wider trim sizes, and color books — perfect if your book relies heavily on images or design.
Payment and Tax Considerations
KDP pays royalties monthly, but you must submit tax information, especially if you’re outside the U.S. Draft2Digital and Lulu have similar schedules, but some platforms may hold funds until a minimum threshold is met.

Final Thoughts
If your main goal is maximum reach and simplicity, KDP is the best choice. But if you want specialized print quality, bookstore reach, or multi-platform distribution, other self-publishing platforms have distinct advantages. Many successful authors even combine platforms — for example, using KDP for Amazon sales and IngramSpark for bookstores and libraries.
FAQs
1. Can I publish the same book on KDP and other platforms?
Yes, but check the exclusive terms. If you enroll your ebook in Kindle Unlimited, it must be exclusive to Amazon. For print books, you can distribute freely on other platforms.
2. Which platform pays the highest royalties?
It depends. KDP offers up to 70% for ebooks, Lulu can offer 80% after costs for prints, and Draft2Digital takes a cut but distributes widely.
3. Is KDP better for ebooks or print books?
KDP is excellent for ebooks. For print books, other platforms like IngramSpark or Lulu may provide higher quality or more bookstore-friendly options.
4. How much does it cost to publish on KDP?
Nothing upfront. You only pay a portion when the book sells, which comes out of your royalties.
5. Can I reach international readers with KDP?
Yes! Amazon has marketplaces worldwide, but other platforms like IngramSpark can help you reach bookstores globally too.
6. Should I use one platform or multiple platforms?
Many authors combine platforms for the best of both worlds: Amazon for reach and easy marketing, others for quality prints or wider distribution.
Conclusion
Choosing the right self-publishing platform isn’t about which is “better” overall — it’s about which fits your goals. KDP shines in reach, ease, and marketing for ebooks. IngramSpark, Draft2Digital, Lulu, and Apple Books provide specialized advantages that can complement your strategy. By understanding the differences, you can make smarter choices and maximize your book’s potential.
