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.
