Children’s books are often broken up by age categories. Age ranges may vary by publisher. There are, of course, word length and manuscript pages exceptions to the generalizations below.
Picture books — In its broadest definition, a picture book is a book in which the illustrations play a significant role in telling the story. Under this umbrella are several types of books:
Baby books — For infants and young toddlers, these books are generally lullabies, nursery rhymes, fingerplays, or wordless books. The length and format varies with the content.
Toddler books — Very simple stories for ages 1-3 (under 300 words) familiar to a child’s everyday life, or concept books (teaching colors, numbers, shapes, etc.) Books are short (12 pages is average) and the format can be board books (sturdy paper-over board construction), pop-ups, lift-the flaps or novelty books (books that make sounds, have different textures, etc.)
Early picture books — A term for picture books geared toward the lower end of the 4-8 age range. These stories are simple and contain under 1000 words. Many early picture books have been reprinted in the board book format, thus widening the audience.
Picture books — Traditionally, picture books (also called “picture story books”) are 32-page books for ages 4-8 (this age may vary by publisher). Manuscripts can be up to 1000 words, but many publishers are looking for 500 words or less. Plots are simple (no sub-plots or complicated twists) with one main character who embodies the child’s emotions, concerns and viewpoint. The illustrations (on every page or every other page) play as great a role as the text in telling the story. Occasionally a picture book will exceed 1000 words; this is usually geared toward the upper end of the age spectrum. Picture books cover a wide range of topics and styles. Illustrators should check out the Caldecott Medal winners. Writers should look at the Charlotte Zolotow Award winners.
Nonfiction in the picture book format can go up to age 10, 48 pages in length, or up to about 2000 words of text.
Easy readers — Also called “easy-to-read” or “rookie readers,” these books are for children just starting to read on their own (age 6-8). They have color illustrations on every page like a picture book, but the format is more “grown-up” — smaller trim size, sometimes broken into short chapters. The length varies greatly by publisher; the books can be 32-64 pages long, with 200-1500 words of text, occasionally going up to 2000 words. The stories are told mainly through action and dialogue, in grammatically simple sentences (one idea per sentence). Books average 2-5 sentences per page. See “I Can Read” books.

Transition books — Sometimes called “early chapter books” or “beginning chapter books” for ages 6-9, they bridge the gap between easy readers and chapter books. Written like easy readers in style, transition books are longer (manuscripts are about 30 pages long, broken into 2-3 page chapters), books have a smaller trim size with black-and-white illustrations every few pages. See the “Stepping Stone Books” published by Random House.
Chapter books — Sometimes called “early middle grade” or “early chapter books” for ages 7-10, these books are 45-60 manuscript pages long, broken into 3-4 page chapters. Stories are meatier than transition books, though still contain a lot of action. The sentences can be a bit more complex, but paragraphs are still short (2-4 sentences is average). Chapters often end in the middle of a scene to keep the reader turning the pages. Look at the “Amber Brown” books by Paula Danzinger.
Middle Grade — This is the golden age of reading for many children, ages 8-12. Manuscripts suddenly get longer (100-150 pages), stories more complex (sub-plots involving secondary characters are woven through the story) and themes more sophisticated. Kids get hooked on characters at this age, which explains the popularity of series with 20 or more books involving the same cast. Fiction genres range from contemporary to historical to science fiction/fantasy; nonfiction includes biographies, science, history and multicultural topics. Check out some middle grade novels from the list of Newbery Medal winners.
Young Adult (YA) — For ages 12 and up, these manuscripts are 130 to about 200 pages long. Plots can be complex with several major characters, though one character should emerge as the focus of the book. Themes should be relevant to the problems and struggles of today’s teenagers, regardless of the genre. The Printz Award list contains many worthy titles.
Notes: I don’t know where I got this info originally–it was something typed up with no author reference. I have seen variations online as if solely written by that person. I have updated some of the information. -Sue
