What Is a Picture Book? Length, Ages and Format

By AuthorWings editorial team 8 min read

Short answer

A picture book is a children’s book in which the pictures and the words tell the story together. It’s usually 32 pages long, made for children of about 3 to 7, and meant to be read aloud by an adult. It usually has a few hundred words and art on nearly every spread.

Picture books are often a child’s first stories, and the format has conventions of its own: a usual page count, art on nearly every spread and words written to be heard. This guide explains what makes a book a picture book, its usual ages, length and format, the parts of a picture book and the main types, with examples. If you’re making one, our picture book publishing page shows what each route costs.

What makes a book a picture book

In a picture book, the pictures do part of the telling. Take them away and the story loses much or all of its meaning. The Caldecott Medal rules, set by the Association for Library Service to Children (a division of the American Library Association), describe a picture book as one that essentially provides the child with a visual experience, with a story, theme or concept developed through its series of pictures.

Three things usually mark the form:

  • The art carries the story. It shows what the words leave out: a character’s face, a joke in the background, the thing hiding behind the door. That’s why the picture book illustration matters as much as the text.
  • It’s read aloud. An adult reads the words while the child reads the pictures, so the text is written to be heard.
  • One idea per spread. Each pair of facing pages moves the story one step, and the page turn holds back the next surprise.

Picture book vs illustrated book

Not every children’s book with pictures is a picture book. In his book Writing with Pictures, author and illustrator Uri Shulevitz drew the line this way: a story book (what many now call an illustrated book) can be understood without its pictures, while a true picture book tells its story mainly or entirely through them.

A collection of fairy tales with a painting every few pages is an illustrated book. Rosie’s Walk by Pat Hutchins, in which the text never mentions the fox chasing the hen, is a picture book: without the art, there’s no story.

Picture book ages, length and format

FeatureTypical picture bookMore detail
Reader ageAbout 3 to 7; some non-fiction and older picture books reach 8 and upThe adult reads aloud; the child follows the pictures
Length in wordsUsually a few hundred, often under 600 for fiction; non-fiction runs longerWord counts by age are in our main guide
Page count32 pages, sometimes 24, 40 or 48Why 32: see how many pages a children’s book should be
ShapePortrait, square or landscape, usually larger than a novelThe shape is chosen to suit the art
BindingUsually hardcover from US trade publishers; self-published books often add a paperbackSome popular titles also come out as board books
EbookA fixed-layout ebook, so each page stays as designedNeeds picture book formatting, not a reflowable layout

Parts of a picture book

Picture book anatomy

Parts of a picture book, front to back

  1. 1

    Jacket and cover

    The first picture a child sees, with the title and the main character.

  2. 2

    Endpapers

    The folded sheets that join the inside covers to the pages, often patterned or used for a small scene.

  3. 3

    Title page

    Title, author and illustrator, often with a small picture that starts the story.

  4. 4

    Copyright and dedication

    The legal page and the author’s dedication, often on one spread.

  5. 5

    Spread

    Two facing pages that work as one picture. The story happens here, about 14 times.

  6. 6

    Gutter

    The fold down the middle of a spread. Faces and words are kept out of it.

  7. 7

    Page turn

    The moment between spreads, where the next surprise waits.

  8. 8

    Back cover

    The blurb, barcode and often one last picture.

In a book with separate endpapers, the endpapers aren’t counted in the 32 pages.

Planning what goes on each spread is a step of its own. Our main guide shows how to plan the 32 pages, spread by spread.

Types of picture books, with examples

Picture books share a format, but not a purpose. These are the main kinds.

TypeWhat it doesExample to study
Story picture bookTells a story with a beginning, a problem and an endingKnuffle Bunny, Mo Willems
Concept bookTeaches an idea such as colors, numbers or the alphabetFreight Train, Donald Crews
Rhyming picture bookTells the story in verse with a steady beatThe Gruffalo, Julia Donaldson and Axel Scheffler
Wordless picture bookTells the whole story in pictures. See wordless picture booksFlotsam, David Wiesner
Non-fiction picture bookExplains real things: nature, science, history, livesOver and Under the Snow, Kate Messner and Christopher Silas Neal (narrative non-fiction)

Rhyme is often the hardest of these to get right, because one forced rhyme or wobbly beat stands out when read aloud. A picture book editor checks the meter beat by beat. Board books are a separate format, often sturdier, shorter editions of picture books; see what a board book is.

How picture books compare with other children’s books

A picture book sits between the board book and the first books a child reads alone.

Board bookPicture bookEarly readerChapter book
Reader age (about)0 to 33 to 75 to 87 to 10
Who reads itAn adult, with the child pointingAn adult, aloudThe child, learning to readThe child, alone
PicturesOn every pageOn every spread, carrying the storyOn most pages, helping with the wordsEvery few pages
Typical length12 to 24 thick pages32 pagesAbout 32 to 64 pagesAbout 48 to 128 pages

A short history of the picture book

The picture book as we know it took shape over roughly the last 150 years.

  • 1878: Randolph Caldecott’s first picture books appear. The Caldecott Medal is later named after him.
  • 1902: Frederick Warne publishes Beatrix Potter’s The Tale of Peter Rabbit, a small book with a picture on every opening, after Potter printed it privately in December 1901.
  • 1928: Wanda Gág’s Millions of Cats comes out, often called the oldest American picture book still in print.
  • 1938: The first Caldecott Medal for the most distinguished American picture book goes to illustrator Dorothy P. Lathrop for Animals of the Bible, with text selected by Helen Dean Fish.
  • 1963: Maurice Sendak’s Where the Wild Things Are is published. It wins the Caldecott Medal the next year.

Frequently asked questions

What age are picture books for?

Usually about 3 to 7, read aloud by an adult. Babies and toddlers are better served by board books, and some picture books, especially non-fiction, are written for children of 8 and up. The Caldecott Medal defines children as anyone up to and including age 14, and picture books for that whole range are eligible, so a picture book isn’t only for the very young.

Is a picture book fiction or non-fiction?

Either. Many picture books tell a story, but non-fiction picture books explain real things, from how snow shelters animals to the life of a scientist. Non-fiction picture books often have more words than story picture books and may add extra facts at the back.

Can adults read picture books?

Yes, and the best ones are written with the adult in mind too, since they’re the one reading aloud. Some picture books handle grief, history or big ideas in a way older readers value as well. A good one holds up on the 50th reading; see what makes a good children’s book.

What’s the difference between a picture book and a storybook?

“Storybook” is a looser term. An illustrated storybook usually has more text per page, and the story still makes sense without the pictures. Shulevitz calls this a story book. In a picture book, the pictures carry part of the story, the text is shorter, and the book is planned spread by spread.
