KDP vs IngramSpark for Children’s Books: Choosing the Right Path for Your Book
When you’re self-publishing a children’s book, there comes a point where the question shifts.
It’s no longer just “How do I make this?”
It becomes: “Where does this book actually live?”
For most authors, that decision comes down to two platforms:
Amazon KDP and IngramSpark.
Both are widely used. Both can produce beautiful books.
But they’re not the same—and choosing between them isn’t always as straightforward as it seems.
Two Different Paths
KDP is often where authors begin.
It’s simple to use, requires no upfront cost, and allows your book to be printed and sold directly through Amazon. For many first-time authors, that accessibility is a relief. You can move from finished files to a printed book relatively quickly, without too many technical barriers.
IngramSpark, on the other hand, opens a different kind of door.
It connects your book to a wider distribution network—bookstores, libraries, and retailers beyond Amazon. It feels, in many ways, closer to traditional publishing. But with that comes a bit more structure, and a bit more precision in how everything is set up.
Where the Differences Start to Matter
On the surface, both platforms offer print-on-demand services. But the experience of using them—and the expectations behind them—can feel quite different.
KDP is designed to be approachable. It allows for a more flexible setup, which can be helpful when you’re learning as you go.
IngramSpark tends to be less forgiving. It expects your files to be prepared carefully from the beginning, especially when it comes to layout, margins, and sizing.
This is often where authors start to feel the difference—not in the idea of publishing, but in the details that sit underneath it.
A Note on Book Size
One of the more subtle (and often overlooked) differences between platforms is the range of sizes they support.
Your book size—sometimes referred to as trim size—affects everything from how your illustrations are composed to how your pages are laid out.
And once that decision is made, it’s not something that’s easily changed.
If you’re still at the stage of deciding what size your book should be, it’s worth taking the time to think that through first.

So… Which One Is Right?
There isn’t a single answer—and that’s often what makes this decision feel a bit unclear.
Some authors choose KDP because it allows them to move forward simply, without overcomplicating the process.
Others are drawn to IngramSpark because of where it can take the book beyond Amazon.
And many, over time, end up using both.
What matters most is not choosing the “best” platform—but choosing the one that fits where you are in the process, and what you want your book to become.
A Quiet Consideration
One thing that often isn’t talked about is how much of the publishing experience comes down to preparation.
The platform itself is only one part of it.
How your files are set up, how your book is designed, and how everything comes together before it’s uploaded—those are the pieces that tend to shape the final result far more than the platform alone.
Final Thoughts
KDP and IngramSpark are simply two different ways of bringing your book into the world.
Neither one is inherently better than the other.
But understanding how they differ—and where each one fits—can make the process feel a little more grounded, and a little less overwhelming.
Working Together
At The Painted Acorn, I work with authors to create children’s books that feel cohesive from the very beginning—so that when it comes time to publish, the foundation is already in place.
