Understanding children's book age groups featured image

Including genres, word counts, and lots of examples!

Here at Get Your Book Illustrations we have the pleasure of working with many children’s book authors to provide them with illustrations for their fiction or nonfiction books.

I’ve seen some confusion on more than one occasion about age groups.

Confusions like:

  • Do I really have to choose an age group for my book?
  • How do I choose which age group to write for?
  • How do I know if my book is right for my intended age group?
  • What are the differences between books for different groups?

[spacer height=”20px”]Let’s start by answering the first question right now.

Yes, you need to choose an age group.

Having a clear age group for your children’s book is crucial. Children grow in their ability to understand and sense of humour, and what they enjoy changes. A book for a 1-year-old, 4-year-old, 10-year-old and 16-year-old are all vastly different.

So we’re going to go over:[spacer height=”-20px”]

  • The different age groups and types of books for each
  • Examples of each and every kind of book mentioned

Crucial considerations for authors concerning age groups

There are a few important points for authors to keep in mind when choosing and writing for your age group:

  • Write for the group you WANT to write for, not the one you feel you “should” write for, for any other reasons.
  • Following from that, write what you enjoy reading or are drawn to.
  • Read a lot of books for this age group (in the genre you write in or want to write in).
  • Build an audience in one age group first before writing for another (if you want to change). Else you’re more or less starting over each time.
  • The main character(s) in children’s books for any age group should be slightly older than the audience the book is intended for.

What is a children’s book?

Firstly, what is classified as a children’s book? It may surprise you that it covers books for ages 0 all the way to 18. So YA (young adult) books also fall in the children’s book category.

These are guidelines. If you search, you’ll see the descriptions of these groups vary from website to website, but not greatly.

You’re probably clear on if your book is for young children or teenagers, but let’s go into the more specific subdivisions.

The different age groups and types of books for each

Here’s a quick list of age groups and the different kinds of books for them:[spacer height=”-20px”]

  • Newborn to age 4: Picture books in the form of board books and soft books
  • Ages 2–5: Early picture books
  • Ages 5–8: Picture books, coloring and activity books and novelty books
  • Ages 4–8: Early (easy) readers
  • Ages 6-9: First chapter books and graphic novels
  • Ages 8–12: Middle-grade novels and graphic novels
  • Ages 12-18: Young adult (YA) novels and graphic novels
  • Nonfiction books also exist for all these age groups

A note on illustrations and age groups

Even though the story, word count and book types vary from age to age, most illustration styles can work for any age group.  

Your options are many. The main thing to keep in mind is if a kid in your age group will like and understand the drawings. Too abstract won’t work for toddlers. Too baby-ish may put off older kids.

Young adult books rarely contain illustrations, but could still have (especially for the cover).

Top tip: Look at other books for your age group to see what is selling.

Picture Books

A picture book is a book where the text and drawings work together to tell the story. Without the illustrations, the book won’t make sense or will be incomplete.

Picture books are meant to be read out loud, so write them with that in mind. In fact, read them out loud and make sure they read well, have a good flow and sound great.

Picture books exist for different age groups from age 0 to 8, so you’ll see it a few times below.

Age 0 to 4 years-board and soft picture books

function to get a better look at these books.**


Board books for babies and toddlers are shorter with lots of full-color illustrations. These can be story books, or concept or novelty books.

Concept books can deal with almost any subject. These books teach factual information with illustrations and text (often single words). Common concepts covered are shapes, body parts, colors, spatial relationships, counting, the alphabet, opposites, and animals.

Novelty books are books with pop-ups, flaps to lift, textures or buttons for sound, or with pages that fold out like a concertina.

Board books are commonly 12 to 16 pages and word count is under 200 words for babies and 500 words or fewer for toddlers.

Age 2 to 5 years–early picture books

Picture books for kids aged 2 to 5 years can have up to 800 words, but it’s best to aim for under 500 words. These books average 32 pages and have lots of full-color illustrations (usually on every page).

The most common types of picture books are story (or fiction), concept, activity, and novelty picture books. These can overlap (for instance, a book can be a concept and a novelty picture book). These can also be written in rhyme.

Age 4 to 8 years-Early (or Easy) readers

Classified as early readers, this age group is a step up from picture books. The best books for this age group are short books with lots of illustrations. Word count can range from 1000 to 3000 words.

Short books often come in a series to enable kids to devour one after another. This helps them build their reading skills.

Big Shark, Little Shark by Anna Membrino

Age 6 to 9 years-chapter books

After short books, we have chapter books. Like short books, they also often come in series, but the word count is higher: 5,000 to 10,000 words per book.

These books usually contain sketches and not full-color illustrations.

Age 9 to 12 years-middle grade

Middle graders want books with an advanced story and prose. At this age, readers have advanced readers skills. As such, they can read books with 30,000 to 50,000 words per book.

These books have fewer or sometimes no illustrations.

Age 12 to 18 years – young adult

YA books are sometimes divided into two age groups, which are 12 to 15 and 16 to 18. An interesting point to note, though, is that about 50% of YA readers are adults.

The typical word count falls between 50,000 to 80,000 words.

Nonfiction books

There are nonfiction books for all age groups. These include biographies, autobiographies, books on countries, animals, history and other factual information. These are often illustrated or contain photos.

Nonfiction books frequently have a higher word count than their fiction counterparts for the same age group.

Are you excited to dive into age groups now that you know more about them?

Choosing an age group is a big step in your journey and has a lot to do with the success of your book. I hope this article has been a great help!

The best advice I can give is to look at many books in the age group(s) you are interested in. Get familiar with their topics, how they’re written, laid out and illustrated. This is the best way to learn.

If you are writing for any of the younger age groups, having the right illustrations is critical. We’d love to help you with this step of your author journey. If you’d like, have a look at our portfolio here.  Or schedule a call if you want to chat or have some questions!

I’d love to hear from you in the comments!
