Children's books, by age
by Stewart Ferris
Age category fixes length, vocabulary, and how much of the story the pictures do. The protagonist is usually a little older than the youngest intended reader. Wrong length is one of the most common reasons a children's manuscript is rejected before anyone reads the story.
| Category | Reader age | Typical range | Sweet spot |
|---|---|---|---|
| Board book | 0–3 | 0–100 | Under 50, or none |
| Picture book | 3–8 (often 4–7) | 200–800 | Around 500 |
| Early / levelled reader | 5–8 | 500–2,500 | 1,000–2,000 |
| Chapter book | 6–10 | 5,000–15,000 | 6,000–12,000 |
| Lower middle grade | 7–10 | 20,000–35,000 | 25,000–32,000 |
| Middle grade | 8–12 | 30,000–55,000 | 35,000–45,000 |
| Upper middle grade | 10–14 | 40,000–65,000 | 45,000–55,000 |
Board books
Board books are objects: thick pages, a dozen to twenty-four of them, built for hands and mouths. Many have no plot. They name a routine, a concept, or a feeling. If the manuscript needs a paragraph a page, it is a picture book.
Picture books
Picture books are a 32-page signature product, with about 28 pages left for story after title and endpapers. Modern taste runs short. Three hundred to 800 words is the common band; many editors prefer under 500, and over 1,000 is a hard sell unless the book is nonfiction. Nonfiction picture books can stretch toward 800–1,500 because they carry facts the art cannot. Leave room for the illustrator. Do not describe what the picture will show. A read-aloud much past ten or fifteen minutes tires the listener and the adult.
Early readers
Early readers are the first books a child reads alone, often levelled. Controlled vocabulary, short sentences, illustration on most pages, one problem solved. About 500–2,500 words, sometimes 3,500 at the top level.
Chapter books
Chapter books bridge early readers and novels: short chapters, one point of view, black-and-white art every few pages. Five thousand to 15,000 words is the usual ask; the older end of the band sometimes reaches 20,000. The Magic Tree House books, a format benchmark, sit around 6,000–10,000. Chapters should end on a small hook. These readers are still building stamina.
Middle grade
Middle grade is a full novel for independent readers of about 8–12, protagonist usually 10–13. Thirty thousand to 50,000 words is the centre of the market. Younger middle grade can live at 20,000–35,000. Upper middle grade, sometimes shelved as tween, runs 40,000–55,000 and occasionally toward 65,000. Fantasy, historical, and adventure earn extra room; 55,000–70,000 is tolerated more often there than in contemporary. SCBWI's long-standing page guidance converts to roughly 25,000–62,500 words, which matches this spread. Themes can be serious. The camera stays at the child's height. Romance, if any, is a crush, not the plot.
