The First Step to a Stronger, More Publishable Children’s Book
The KidLit Creator’s Chronicle – Issue #15
Hi,
I’ll never forget the journey of one of my coaching members. She had just completed her “picture book” draft and was excited to refine and publish it. At that point, I hadn’t seen the manuscript, but the concept was quite unique and heartfelt. But as she worked on it, she struggled to make it work. She let me know the word count was high, but the story was still very incomplete, as she really wanted to add much more to it. I advised that she look at the different children’s book categories and see what type of book she was actually writing.
She adjusted it into an early chapter book. But even then, it didn’t fit. I asked to have a look at the manuscript and suggested lower middle grade, since the character’s emotional journey was too complex, and she wanted to tackle a serious topic in a way that was more suitable for older kids. After many hours of initially trying to cut, rewriting, reworking, and expanding, she finally landed on a full chapter book. Then, the book still ended up being too long and complex, and she had to adjust again!
While she learned a lot, this made the process much harder than it had to be. She spent months learning a new categories’ expectations and rewriting to match. If she had known more and carefully chosen her category before writing, she would have saved herself an incredible amount of time and rework.
And she’s not alone. This happens more often than you might think.
Choosing the right category from the start shapes so much: your word count, your vocabulary, your story arc, even how your book is marketed.
Part of the challenge was that my coaching member had envisioned a longer, more detailed story, but hadn’t fully realised at the start what that would require.
This is why understanding the categories before you begin is so important.
When you know the typical length, structure, and pacing of each category, you can shape your story idea with the right expectations. Having clarity early doesn’t limit your creativity, it gives it the right container to create in.
Your Category is Your Foundation
If you’re writing a children’s book, one of the most important decisions you’ll make is choosing your book’s category. As I just went over, you should do this early on in the process, ideally before you ever write the book.
It might seem like a small detail, but knowing your category from the start shapes everything about your project. Each age group—whether toddlers, early readers, or middle grade kids—has different needs and expectations. These differences affect your word and page count, the vocabulary you should use, the style of your storytelling, humour, the type and amount of illustrations, and even how you’ll market the finished book.
Children’s books range from around 50 to 50,000 words, and from baby to teen. This is a huge scope, with vast differences between different categories.
When you start writing without a clear category in mind, it’s easy to end up with a manuscript that falls awkwardly between formats, making it much harder to publish and harder for readers to connect with.
Choosing the right category early helps you write a stronger, more marketable book and makes your whole creative journey much smoother.
Choosing the right fit for your idea is what makes the writing process smoother and the book stronger.
Important Note:
It’s worth knowing that many stories can be reshaped to fit different categories.
For example, my coaching member could have condensed the absolute highlights of her character’s journey into a 600–700 word story, much like a picture book biography covers years of a person’s life in a few scenes.
But the decision to expand or condense a story must be intentional. It doesn’t only affect the word count. It impacts the pacing and the emotional journey and what the reader ultimately experiences.
How to Make Sure Your Book Fits Its Category
Once you understand how crucial categories are, the next step is making sure your book fits the one you’ve chosen. Here’s how to do it:
1. Understand the Expectations for Each Category
Each children’s book category has typical word counts, structures, illustration styles, and themes. For example:
Board Books (Ages 0–3)
- Word Count: 0–200 words.
- Focus: Basic concepts (colours, numbers, animals, daily routines).
Illustrations: Bright, simple pictures that fill every page. Illustrations often carry most of the concept, with very minimal supporting text.
Early Picture Books (Ages 2–5)
- Word Count: 20–500 words.
- Focus: Simple stories, rhythm, repetition, or basic concepts like emotions or counting.
- Illustrations: Full-page artwork that supports and extends the text, helping young children understand the story and adding depth.
Picture Books (Ages 5-8)
- Word Count: 500–800 words.
- Focus: Full story arcs (beginning, middle, end). Often emotional, funny, or meaningful.
- Illustrations: Detailed, full colour spreads supporting and often providing extra detail not explicitly stated in the text.
Nonfiction Picture Books (Ages 5–12)
- Word Count: 800 (or less)–3,200 words.
- Focus: True facts presented through narrative or expository formats.
- Illustrations: Either full colour illustrations or photographs, adding information and clarity.
Early Readers (Ages 4–8)
- Word Count: Depending on the level:
- Level 1 (Ages 4–6): 32–150 words
- Level 2 (Ages 6–7): 100–500 words
- Level 3 (Ages 7–8): 500–1,000 words
- Focus: Simple sentences and short paragraphs, adjusted to each age level.
- Illustrations: Illustrations on every page, or every 2-4 pages for older kids. Colour images that match the text closely, helping readers decode meaning.
Early Chapter Books (Ages 5–7)
- Word Count: 1,000–6,000 words.
- Focus: Slightly longer stories with short chapters.
- Illustrations: Illustrations on every page or spread for younger readers. May be full colour or black and white.
Chapter Books (Ages 7-9)
- Word Count: 5,000–10,000 words.
- Focus: More developed plots and characters.
- Illustrations: Black-and-white images, usually every second spread or less frequently.
Lower Middle Grade (Ages 8–12)
- Word Count: 10,000–25,000 words.
- Focus: Complex storylines and layered themes.
- Illustrations: Sometimes small black-and-white images every few spreads or once per chapter.
Upper Middle Grade (Ages 10–14)
- Word Count: 20,000–55,000 words.
- Focus: Deeper, more mature topics, sometimes with multiple character arcs.
- Illustrations: Very few; perhaps a chapter header or occasional interior image.
Tip: Use your target age range as your anchor. Every choice you make–word choice, plot complexity, humour, emotional depth–should match where your readers are developmentally.
2. Read 5–10 Books in Your Chosen Category
Before you get deep into writing, spend time reading published books in your category. Pay attention to:
- Story length and pacing
- Sentence structure and vocabulary
- How illustrations are used to support or extend the story.
- Common themes and emotional tone.
This will give you a strong understanding for what readers, parents, teachers, and publishers expect and help you avoid common missteps.
3. Use a Simple Category Checklist
Before you commit to your manuscript (and when you revise), use a quick checklist to make sure your project fits your chosen category:
- Word Count: Am I within the typical range for this type of book?
- Theme and Content: Are my topics, themes and tone appropriate for the target age group?
- Language: Is my writing style right for my readers’ vocabulary and comprehension level?
- Illustrations: Am I planning the correct style and amount of illustration?
- Market Fit: Have I studied enough successful books in this space to know how mine will compare, where it will fit, and how it will stand out?
If you can confidently tick each box, you’re setting yourself and your book up for success.
Pro Tip:
While reading comparable books, take notes on specific patterns you spot.
- How do the first pages start?
- What kind of opening lines hook the reader?
- How much dialogue is there compared to description?
These small details can make the difference between a manuscript that feels polished and one that feels mismatched.
“A Good Story Will Find Its Place”
You might have heard something along the lines of, “If the story is good enough, it will find its place.”
It’s a nice idea, but for children’s books, it’s simply not true.
In reality, publishing (and selling) a children’s book is about far more than just good writing. It’s about fit and trust: fitting the expectations of a clear category, fitting the developmental stage of the readers, fitting the practical needs of publishers, teachers, and parents.
When a manuscript doesn’t fit a recognised category, for example, it’s too long for a picture book but too short for a chapter book, it’s not seen as unique. It’s seen as confusing. Publishers don’t know where to shelve it. Booksellers don’t know how to recommend it. Readers don’t know what to expect from it. And confusion kills sales, no matter how beautiful the writing may be.
Confused buyers walk away. That’s why a strong story needs the right container.
Without it, even a wonderful idea can end up overlooked or endlessly rejected. That’s why deciding your category early is not about limiting your creativity. It’s about giving your story the best chance to succeed.
Real Examples
Understanding how real children’s books fit their categories makes it much easier to write your own book. Here are a few examples that show just how closely successful books match the expectations for their age group and format:
Early Readers:
First Little Readers by Scholastic
This collection contains different reading levels, and the Level 1 early readers are tailored for 4–6-year-olds, with each book using between 16 and 150 simple words.
These sets are sorted into groups A, B, C, and so on, gradually increasing in word count and complexity as the levels progress.
The language is very simple, with short sentences and repetitive phrasing.
There are plenty of illustrations that directly match the text, helping new readers decode words through context clues, which is exactly what early readers need.
Picture Book:
The Leaf Thief by Alice Hemming
This picture book is for children aged 3–6 and contains approximately 375 words. It features a simple yet complete story arc, and is fully illustrated. The illustrations enhance and tell parts of the story that are not in the text.
Early Chapter Books:
Mercy Watson to the Rescue by Kate DiCamillo, which is aimed at readers aged 5–8 and has a word count of about 1929 words.
Another example is Frog and Toad Are Friends by Arnold Lobel is tailored for readers aged 5–8 and contains 2281 words, fitting well within the early chapter book category.
Both of these exemplify the characteristics of early chapter books: simple yet interesting plots, age-appropriate vocabulary, and supportive illustrations on every page that aid comprehension.
Each of these books succeeds because the author and publisher understood their category and created the book specifically to meet the expectations of that age group.
From word count to illustration style to sentence complexity, every element aligns, giving readers, parents, and educators exactly what they would expect from a book in that category.
