How to Write Children’s Book Projects

Writers often ask the interwebs for advice on how to write children’s book projects or for ideas for such books. However, “children’s book” is an ambiguous description - it actually encompasses several different types of literature. Knowing this and avoiding generalizing the “children’s book” as one type of product is vital if you want to succeed in the kidlit publishing industry.

The earliest books for young readers are board books, then picture books, early readers for kids starting to read independently, then novel-like chapter books, middle grade novels, all the way up to young adult novels for teens (and, let’s face it, some adults, too).

Figuring out how to write children’s book projects doesn't have an easy answer. That said, there is a shared quality among children’s book writers: They all recognize the importance of engaging young readers. Kids get incredibly invested in the stories and characters they read, making the time they spend reading so transformative.

Those aspiring to write books for kids respect these little readers without ever preaching or condescending them. Drawing on their own childhood memories, these writers create stories that access their audiences emotionally and show how much they care about connecting with kid readers.

But to really succeed in the children’s book market, you need to figure out what you’re writing, how long it is, and which category you’re targeting. Read on to learn more, so that you don’t use this generic term again.


How to Write Children’s Book Projects: Age Group

The age range of children’s book readers contains various bands. Here are the different categories you can get into if you want to know how to write children’s book projects, starting with the youngest and ending with the oldest:

  • Board Book Age Group: 0 to 2

  • Young Picture Book Age Group: 2 to 4

  • Picture Book Age Group: 4 to 6

  • Nonfiction Picture Book Age Group: 5+

  • Early Reader Age Group: 5 to 7

  • Chapter Book Age Group: 6 to 8

  • Young Middle Grade Age Group: 8 to 10

  • Middle Grade Age Group: 9 to 12

  • Upper Middle Grade Age Group: 12+

  • Young Adult Age Group: 13+

  • Young Adult Fantasy Age Group: 13+

  • New Adult Age Group: 16+

You may see some similarities between the levels. This is because children reach different levels of reading skill at different ages. Therefore, some of these specs are more like suggestions than definite cut offs.

How to Write Children’s Book Projects: Word Count

The best children's books capture their readers' imaginations and inspire a lifelong love of reading. However, the number of words in a children's book depends on its intended audience: younger readers may have shorter attention spans, while older readers crave more complex stories.

If you're wondering how to write children's book projects with the right number of words, start by considering your target audience. Here is a breakdown of word counts for children's books, categorized by age group:

  • Board Book Word Count: Up to 100

  • Young Picture Book Word Count: 400

  • Picture Book Word Count: 600

  • Nonfiction Picture Book Word Count: 1,000 to 3,000

  • Early Reader Word Count: 300 to 1,200

  • Chapter Book Word Count: 1,500 to 10,000

  • Young Middle Grade Novel Word Count: 15,000 to 30,000

  • Middle Grade Novel Word Count: 30,000 to 55,000

How to Write Children’s Book Projects: Page Count

In the publishing realm, manuscripts are usually talked about with respect to word count. Those interested in how to write children's book projects should take the following page counts into account:

  • Board Book Page Count: 16 to 24

  • Young Picture Book Page Count: 24 to 32

  • Picture Book Page Count: 32 to 48

It's important to remember that page count matters more in the context of published books. Younger readers' books usually have predetermined page counts, while novels typically have variable page counts due to font size and book layout.


Special Considerations of How to Write Children’s Book Projects

As you focus on what kind of children's book you plan to write, you'll need to consider how one of the main ingredients of getting it published will be illustrated. A child reader's eyes are often drawn to the illustrations in a book more than the words, so creating visually appealing artwork is essential when you’re wondering how to write children’s book projects.

But before you start learning about illustrating children’s books or hire a children’s book illustrator, keep in mind that only board books, picture books, and early readers are typically illustrated. Chapter books do tend to have some art, though it may be spot illustration (the occasional pages of art, or art accompanying the chapter headings).

Remember that children’s book illustrations have become highly specialized and vastly different from what hobby artists typically create. Your own art will likely not be competitive with the high-quality illustrations seen in today’s market, unless you’re a professional artist. You might not need to hire a professional illustrator before submitting your project to a publisher, either.

Publishers have their own policies when it comes to selecting illustrators, so most of the time, projects are pitched as text. If you are a talented children's book illustrator, you can submit your text and illustrations together as an author-illustrator. Otherwise, it would be wise to take the simpler route and just submit the text for consideration.
