Picture books, fiction and nonfiction, are generally 24 or 32 pages. Although there are some wordless picture books, there is usually a good balance between the words and the illustrations, each supporting the other in a seamless presentation. In general, picture books are aimed at young children between the ages of three and seven. Recently published picture books tend to have less than 800 words.
Early Chapter books are written for children who are just beginning to read on their own. The books are usually labeled for six- to nine-year-olds, but reading readiness depends on the child. EC books are approximately 32 pages, have shorter sentences, and include line drawings or illustrations throughout the story to show the action and/or humor. By their trim size, early chapter books are designed to make children feel like “real” readers. EC books can cover every genre of literature, from contemporary stories to nonfiction to mysteries to poetry to fantasy and science fiction.
