How to Write a Children’s Book That Actually Sells

By Kezzia Crossley

You have a story inside you — a message, a memory, a character whispering in your ear. You want to write a children’s book. Maybe you already have. But now you’re wondering… how do I write a children’s book that actually sells?

Here’s the truth: there’s no formula. But there are patterns. And if you understand your readers, your market, and your craft, you can create a book that’s not only beautiful — but sellable.

Let’s talk about how to do both.

Know Your Reader (Hint: It’s Not Just the Kids)

Children’s books are bought by grown-ups, read by grown-ups, and curated by librarians, teachers, and parents. So while your story should delight kids, it also has to resonate with the gatekeepers.

Ask yourself:

  • Will this story feel worthwhile to a parent or teacher?

  • Is the message accessible but meaningful?

  • Does it hold up to repeat readings?

Keep It Tight

For picture books, less is more. Most traditionally published picture books fall between 500–800 words. Every word has to earn its place.

The goal is to say a lot with a little:

  • Use rhythm and repetition

  • Create space for the illustrations to tell part of the story

  • Focus on one emotional arc or transformation

Think Like a Marketer (Without Writing Like One)

Books that sell usually fit into a recognizable theme — but with a fresh twist. Look at what’s working on the market:

  • Social-emotional learning

  • Growth mindset

  • Diversity and inclusion

  • Environmental awareness

  • Humor and bedtime routines

Don't write what’s trendy just to chase sales — but do frame your idea in a way that's relevant. Think: What shelf would this book belong on? What problem does it solve or emotion does it explore?

Make Room for Visual Magic

If you're planning to publish a picture book, don’t describe every single detail. Leave room for the illustrator (and the reader) to imagine. Visual storytelling is half the magic — let your manuscript breathe.

Tip: When you're writing, avoid over-direction like “the dog jumps over a purple rock” unless it's critical. Let the illustrator build their own world around your words.

Test Before You Print

Want to know if your book will sell? Test it.

  • Read it aloud to kids

  • Ask a parent or teacher for feedback

  • Run a short beta reader survey

  • Hire a children's book editor or publishing guide (hey there 👋)

What sells isn't just what you love — it’s what connects with others.

Selling Doesn’t Mean Selling Out

Writing a sellable children’s book doesn’t mean turning your story into a marketing gimmick. It means being thoughtful, intentional, and clear on your why.

At The Painted Acorn, I help indie authors bring their stories to life in a way that feels aligned — creatively, practically, and professionally.

Because a book with heart can sell — and sell well.
