To self-publish a children’s picture book, you write and edit a short text, plan it across a standard page count (usually 32 pages), commission or create the illustrations with clear rights, lay the pages out with bleed at your chosen trim size, then upload to a print-on-demand service such as KDP or IngramSpark and order a colour proof before you publish. The biggest decisions are the age band you are writing for, who owns the illustrations, and which printer can produce the format you want.

This guide includes a few product links near the end. As an Amazon Associate, Freyja Publishing earns from qualifying purchases, at no extra cost to you.

This guide follows that process step by step, explains the technical rules that catch first-time authors out (including page minimums that rule out some formats), and ends with a checklist you can work through.

• Plan for 32 pages. It is the standard picture-book length because of how printers fold sheets, and it shapes how you pace the story.
• Get illustration rights in writing before any artwork is made, covering every format you might use.
• KDP hardcovers need at least 75 pages, so a 32-page picture book hardcover usually means using another printer, such as IngramSpark.
• Use premium colour on KDP for a short picture book, as standard colour needs at least 72 pages.
• Set the reading age on KDP, or your book may not appear in age-based children’s categories and searches.

At a glance

• Plan a picture book for 32 pages, the standard length because of how printers fold sheets.
• Get illustration rights in writing before any artwork is made, covering every format you might use.
• KDP hardcovers need at least 75 pages, so many authors use IngramSpark for a 32-page hardcover.
• On KDP, use premium colour for a short picture book, because standard colour needs at least 72 pages.
• Lay out pages with 0.125 inches (3.2 mm) of bleed and set the reading age so the book appears in children’s categories.
• Always order a printed colour proof, because colours on screen look brighter than ink on paper.

Step 1: Choose your age band and book type

“Children’s book” covers very different products. Decide which one you are making before you write a word, because it sets the length, vocabulary and format. KDP’s reading-age guidance uses these bands, which match common bookshop practice:

Age band	Typical book type	What it usually means for you
0 to 2	Simple picture books with few or no words	Very short text, bold images; board books need specialist printing
3 to 5	Picture books	Short text read aloud by an adult, illustrations on every spread
6 to 8	Early readers and first chapter books	Controlled vocabulary for independent reading, fewer illustrations
9 to 12	Middle-grade chapter books	Novel-length text, often black-ink interiors

This guide focuses on the 3 to 5 picture book, which is the most common self-published children’s format and the one with the most technical traps. Board books, with thick card pages, are generally not available through the main print-on-demand services, so they usually mean working with a specialist printer and a print run.

Step 2: Write and edit for reading aloud

Picture-book texts are short, and every word has to earn its place. Because an adult usually reads the book aloud, rhythm and repetition matter as much as vocabulary.

• Leave room for the pictures. Do not describe what the illustration will show; let the art carry it.
• Write in page turns. A page turn is a natural pause, ideal for a reveal or a joke.
• Read it aloud repeatedly, ideally to children in your target age band, and notice where you stumble.
• Check reading level if the book is meant for independent readers. Readability scores built into word processors, such as Flesch-Kincaid, give a rough guide, though they work best on longer passages and are no substitute for testing with real readers.
• Get an edit from someone who knows children’s books. A short text makes editing relatively inexpensive, and errors in a picture book are very visible.

If you are writing for your own children or grandchildren as well as for sale, the guide to building a lifelong love of reading has ideas on what keeps young readers coming back to a book.

Step 3: Plan the 32 pages

Printers make books from large sheets that are folded into groups of pages called signatures, usually 8 or 16 pages each. That is why picture books are almost always 24, 32 or 40 pages, with 32 the most common. Print-on-demand printers are more flexible, but planning in multiples of eight keeps your book compatible with offset printing later.

Not all 32 pages hold story. You need space for a title page, a copyright page and possibly a dedication, which leaves fewer pages for the text itself. Endpapers, the decorative pages inside the cover of a hardcover, are sometimes printed as part of the page count (“self-ended”) and sometimes added separately, depending on the printer. Check your printer’s specifications before you plan.

Make a thumbnail map: draw 16 small spreads on a single sheet and sketch what happens on each. This shows pacing problems before an illustrator spends time on finished art.

Step 4: Choose a trim size

Picture books are usually larger than novels and often square or landscape. KDP’s common larger sizes for picture books include 8.5 x 8.5 inches, 8.25 x 8.25 inches, 8 x 10 inches and 8.5 x 11 inches. Landscape formats suit wide scenes but are not offered by every printer.

Choose your trim size before illustration starts. Artwork is drawn to a shape, and changing it later means cropping or redrawing. Also note that KDP charges more per page for large trim sizes (wider than 6.12 inches or taller than 9 inches), so a big format costs more to print.

Step 5: Sort out illustration and rights

Illustration is usually the largest cost and the area with the most legal risk. The main routes are illustrating it yourself, commissioning an illustrator, or using licensed stock art, which rarely suits a whole picture book.

What a commission contract should cover

• Ownership or licence. Does the illustrator transfer copyright, or license the art to you? Both are common; what matters is that it is written down.
• Scope of use. Print, ebook, audio cover, translations, marketing, merchandise and territories. If you might sell colouring sheets or plush toys later, say so now.
• Credit. How the illustrator will be named on the cover and in metadata.
• Deliverables. Resolution, file formats, layered files, and whether the cover is included.
• Schedule and payment. Stages (sketches, revisions, finals), how many rounds of revisions, and what happens if either side cancels.
• Use of AI tools. Whether generative AI may be used, which affects what you must disclose to retailers.

Copyright law differs by country. In the US, for example, “work made for hire” has a specific legal meaning, so a contract that simply uses the phrase may not do what you expect. Have a lawyer or a writers’ and illustrators’ organisation in your country review the agreement. The guide to legal basics for self-publishers covers copyright in more depth.

AI-generated illustrations

KDP’s content guidelines require you to tell Amazon if text, images or translations are AI-generated when you publish, even if you edited them heavily afterwards. Using AI only to brainstorm or refine work you created yourself is classed as AI-assisted and does not need disclosure. Either way, you remain responsible for making sure the content does not infringe anyone’s rights.

Step 6: Lay out the pages for print

Picture books almost always have images that run to the edge of the page, which means you need bleed. KDP requires 0.125 inches (3.2 mm) of bleed on the top, bottom and outer edges, so the PDF is slightly larger than the trim size. Other key points:

• Keep text and important details well inside the margins, away from the trim and the gutter.
• Use high-resolution images; 300 DPI is the usual print standard.
• Remember the spine: on a short picture book it is very narrow, and many printers will not allow spine text below a certain page count.
• Use the printer’s own cover template, generated from your trim size, page count and paper.

Step 7: Choose your print options

This is where children’s books differ most from novels. Colour printing costs much more per page than black ink, and page minimums limit which formats are available.

Option	Suits a 32-page picture book?	Key points
KDP paperback, premium colour	Yes	Premium colour is designed for image-heavy books and starts at 24 pages; sold on Amazon
KDP paperback, standard colour	No	Minimum of 72 pages, and better suited to long books with fewer images
KDP hardcover	No	Page range is 75 to 550 pages; also not available on Amazon.co.jp or through Expanded Distribution
IngramSpark paperback or hardcover	Yes	Hardcover options include case laminate, jacketed case laminate and jacketed cloth; distributes to bookshops and libraries through Ingram
Draft2Digital Print	No	Black-and-white paperbacks only
Offset print run	Yes	Lower cost per copy for larger quantities, but you pay upfront and must store and ship the books

Many picture-book authors use KDP for the paperback on Amazon and IngramSpark for the hardcover and wider bookshop and library distribution. The comparison of KDP and IngramSpark explains how the two work together, and the guide to print on demand versus traditional printing covers when a print run makes sense.

Colour printing costs in general terms

KDP and IngramSpark calculate print cost from a fixed charge plus a per-page charge that rises with colour quality and trim size. For a short picture book, the colour premium is the main reason the cost per copy is higher than a novel of many more pages. IngramSpark adjusted its print pricing in February 2026, with some books costing more and others less, and added a small market access fee for books in distribution. Use each platform’s printing cost calculator with your exact trim size and page count, and check that your retail price leaves a royalty after the print cost.

Step 8: ISBNs, metadata and categories

Each format needs its own ISBN. KDP offers free ISBNs for paperback and hardcover, usable only with KDP; IngramSpark requires an ISBN for each print format, and a KDP-issued ISBN cannot be used there. If you plan to use both printers, buying your own ISBNs from your national agency keeps your publisher name consistent. The guide ISBN explained covers the options by country.

On KDP, set the reading age under Primary Audience. KDP states that without an appropriate reading age, a book may not be eligible for its selected children’s categories and will not appear in age-specific search results. Note that customer feedback can change the reading age displayed on the detail page. Choose categories and keywords that parents actually search for, such as the theme of the book; the guide to KDP keywords and categories explains how.

Step 9: Decide on an ebook version

A picture-book ebook needs a fixed layout, so each page displays exactly as designed rather than reflowing like a novel. KDP’s Kindle Create includes a mode for comics and kids’ books, and KDP supports fixed-layout features such as text pop-ups. Apple Books also supports fixed-layout EPUB files. Test your ebook on a phone as well as a tablet, as small screens can make text hard to read.

Step 10: Proof, then publish

Always order a printed colour proof. Colours on screen are lit from behind and usually look brighter than ink on paper, and dark areas can lose detail in print. Check the proof in daylight, look closely at faces and text, and read it aloud one more time before you approve it.

Your step-by-step checklist

1. Choose the age band and book type.
2. Write, read aloud, and get an edit from someone experienced with children’s books.
3. Plan the pages in a thumbnail map, usually 32 pages.
4. Choose the trim size and confirm it is offered by every printer you plan to use.
5. Sign a written illustration contract covering rights, scope and deliverables.
6. Confirm each printer’s page minimums, colour options and endpaper rules.
7. Lay out the interior with bleed, safe margins and high-resolution images.
8. Create the cover from the printer’s template.
9. Assign ISBNs and complete metadata, including reading age.
10. Disclose any AI-generated content as the platform requires.
11. Order and check a printed colour proof.
12. Publish, then check the live listing on each store.

Common mistakes to avoid

• Planning a KDP hardcover for a 32-page book. It falls below KDP’s hardcover minimum.
• Choosing standard colour on KDP for a short book. It requires at least 72 pages.
• Commissioning art without a written contract, or one that only covers print and not the ebook or marketing.
• Changing trim size after the illustrations are finished.
• Placing text too close to the edge, so it is trimmed off or lost in the gutter.
• Skipping the reading age, which can keep the book out of children’s categories.
• Judging colour on screen only, then being surprised by darker printed pages.

If your text is not finished yet, start with how to write a children’s book, which covers age bands, word counts and read-aloud techniques.

Frequently asked questions

How many pages should a children’s picture book be?

Thirty-two pages is the standard, because printers fold sheets into signatures of 8 or 16 pages. Shorter books of 24 pages and longer ones of 40 pages are also common. Remember that the title, copyright and dedication pages come out of the total.

Can I publish a picture book hardcover on Amazon KDP?

Only if it has at least 75 pages, which most picture books do not. Many authors publish the paperback on KDP and use IngramSpark for the hardcover, which can then reach Amazon and other retailers through Ingram’s distribution.

Do I need to own the copyright to the illustrations?

Not necessarily, but you need written permission covering every way you will use them. A licence can work well if it clearly covers all formats, territories and marketing uses. Without a written agreement, your right to use the art can be unclear.

Can I use AI to illustrate a children’s book?

Platforms such as KDP allow it, but you must disclose AI-generated images when you publish. You are still responsible for ensuring the images do not infringe anyone’s rights, and many authors find it hard to keep characters consistent across 32 pages with AI tools.

What reading age should I choose on KDP?

Pick the band that matches who the book is for. KDP lists 3 to 5 for picture books and 0 to 2 for simple books with few or no words. Choose a realistic range rather than the widest possible one, so the book appears in the right searches.

Is an ebook worth it for a picture book?

It can be, as a low-cost extra format, but it needs a fixed layout and careful testing on small screens. Many families still prefer print for picture books, so most authors treat the ebook as secondary.

A self-published picture book is a small book with a lot of moving parts. Settle the age band, page plan, trim size and rights before the art begins, check each printer’s rules, and let a printed proof make the final call.
