Learning how to self-publish a children's book means balancing a simple story with demanding production. A picture book looks easy because the words are few, but every page needs strong art, clean layout and a print file that survives real paper. This guide walks you through age bands, page counts, trim sizes, illustration routes, fixed layout files, pricing and proofs, so you can publish a book children want to hear again and parents trust.
How to Self-Publish a Children's Book, Step by Step
A picture book succeeds in a very specific moment: an adult reading aloud to a child who wants the same page turned again. Every decision you make, from word count to trim size, should serve that moment. Start by naming your reader clearly. Board books are for ages 0 to 3 and use very few words, sturdy scenes and simple concepts. Picture books are usually for ages 4 to 8 and carry a full story in a short text. Early readers sit between picture books and chapter books, with controlled vocabulary and short chapters for children who are starting to read alone.
Most picture books for ages 4 to 8 run between 500 and 800 words. That reflects how long a read aloud lasts and how much text fits beside full page art. If your draft is much longer, look for scenes you can show in the illustrations instead of explaining in words. If it is much shorter, check that the story still has a beginning, a problem and a satisfying ending.
Write your age band into your plan from the start. Retailers and parents shop by age first, so your description, store categories and back cover should all point to the same reader. A mismatch, such as art for toddlers paired with jokes for older children, quietly kills sales even when the story is good.
Write and Test a Story Built for Reading Aloud
Picture book text is heard, not just read. Read every draft out loud and mark the lines where you stumble. Children forgive simple language, but they do not forgive boring rhythm. Vary your sentence length and use repetition on purpose, because young listeners love joining in. Give your main character a clear want in the first few pages, then let each scene raise the stakes.
Plan the page turns
Before you hire anyone, break your story into spreads. A spread is two facing pages, and it is the real unit of a picture book. Sketch rough boxes for each spread, note what the art will show and check that each page turn lands on a small surprise, a question or a funny reveal. This simple storyboard, often called a dummy, saves you money later. It shows which scenes repeat, which pages are crowded and where the text and the art are saying the same thing twice.
Test the dummy on real families if you can. Watch where children look away and where they ask what happens next, and cut the scenes where attention drops. A story that holds three children in a row will usually hold up in print.
Choose a Trim Size and Page Count That Print Well
The traditional picture book standard is 32 pages, including the front and back matter. Print on demand services work in multiples of four pages, and 32 pages gives you room for a title page, the story itself and a simple closing page without wasting paper. Longer books are possible, but each extra spread adds illustration cost and print cost, so add pages only when the story truly needs them.
Common trim sizes include 8.5 by 8.5 inches for a square book, 8 by 10 inches for a portrait book and 10 by 8 inches for a landscape book. Square books suit playful stories and younger readers. Portrait suits taller characters and scenes. Landscape suits wide scenes such as journeys and landscapes. Pick the shape that fits your art, then confirm that your chosen printer offers it in both paperback and hardcover if you plan to sell both.
Paperbacks sell in the highest numbers online, but hardcovers matter for gifts, schools and libraries. Many authors launch both together, using the same interior with adjusted covers. Order a printed proof of each format first. Colours that glow on screen often print darker, and pale text can disappear on paper.
Find Illustrations That Fit Your Budget and Timeline
Illustration is usually the biggest cost and the longest stage of a picture book. You have three main routes. The first is hiring a professional illustrator, found through portfolios and referrals. The second is working with a newer illustrator whose style fits your book. The third is licensing existing art or using simple, design led pages for a concept book, which works only for certain projects.
Whichever route you choose, put the agreement in writing before work starts. Your agreement should cover the number of illustrations, the number of revision rounds, the file types you will receive, the deadline for each stage and exactly which rights you are buying. For a book you plan to sell, you normally need the right to use the art in the book, on the cover and in marketing for the book. Agree who keeps the original files and whether the illustrator can show the work in a portfolio.
Work in stages: character sketches first, then rough spreads, then colour art. Approving characters early prevents the most painful redraws. Keep a shared style note with your colour palette and examples of the mood you want. Feedback on a rough sketch is cheap, and feedback on finished art is not.
Your cover deserves the same care as your best interior spread. It has to read clearly as a small thumbnail, name the age group at a glance and promise the feeling of the story. Study the practical guidance in how to design a book cover that actually sells before you brief your illustrator, so the cover art leaves proper space for the title and your name.
Build a Fixed Layout File That Holds Together
Unlike a novel, a picture book cannot let its text reflow. The words belong in exact places beside exact images, so picture book ebooks use fixed layout files. On Kindle, that usually means building the book with a tool such as Kindle Create, which supports children's books with fixed layout and text pop ups. For print, you will deliver a print ready PDF with the correct trim size, margins and bleed. Bleed is the extra area of art that runs past the page edge so nothing white shows after trimming.
Set your text with generous contrast and a large, clean font. Keep words away from the centre fold and the page edges, where trimming can clip them. Never place important faces or words in the gutter, the inner margin where pages meet. Check every spread at full size, because layout problems hide at thumbnail size.
Image handling is where many first picture books break. Files need high enough resolution for print, consistent colour settings and sensible file sizes for the ebook version. The detailed steps in how to format images and illustrations for Kindle and print will help you prepare art that stays sharp in the paperback and still loads quickly in the fixed layout ebook. Keep your original art files untouched and work from copies, so you can rebuild a page without starting again.
Price, Publish and Proof Your Book in Print
Picture books cost more to print than novels because every page is in colour. Run your numbers before you set a price. Take your page count, trim size and paper choice, check the printing cost for each format, then set a retail price that leaves a sensible royalty after the store share and the print cost are taken out. A price that looks kind to buyers but pays you almost nothing per copy will not fund your second book.
On Amazon, you can publish the paperback and hardcover through KDP and the fixed layout ebook through Kindle. For bookstores, schools and libraries, wide distribution through a wholesale channel matters more, because those buyers order through their normal suppliers. Think about schools early: a discussion question page or a teacher friendly activity at the back can make your book easier for educators to choose.
Proof like a professional
Order printed proofs and read them in daylight, out loud, with a pen in hand. Check skin tones, check that no text sits too close to an edge and check the spine and barcode on the back cover. Ask a friend to read the proof to a child while you watch. Then fix the file, upload the corrected version and, if you changed anything structural, order one more proof. Skipping the second proof is the most common way small errors reach real buyers.
Plan your launch around readers, not just release day. Send review copies to parenting bloggers and local librarians, offer a reading at a nearby school or library and prepare a simple activity sheet adults can print. Picture books spread by recommendation between parents, so make sharing easy.

Frequently Asked Questions
How many pages should a picture book be?
The standard picture book is 32 pages, including title and closing pages. That length fits print on demand rules, keeps illustration and printing costs manageable and matches what parents and teachers expect. Shorter and longer books can work, but 32 pages is the safest starting point for a first title.
How many words should a picture book have?
Most picture books for ages 4 to 8 contain between 500 and 800 words. Younger books use fewer words and rely more on art and repetition. Count only the story text, read it aloud for timing and remember that the illustrations should carry part of the story instead of repeating it.
Do I need a hardcover edition?
A hardcover is not required, but it helps with gifts, schools and libraries, where durability matters and buyers expect a higher price. Many authors publish a paperback for everyday sales and a hardcover with the same interior for those channels. Order a printed proof of each format before launch.
Can I illustrate my own picture book?
Yes, if your art is strong and consistent across every page. Test your illustrations at print size, check that characters look the same from page to page and ask honest readers for feedback. If art is not your strength, hiring an illustrator is usually money better spent than any advert.
What is a fixed layout ebook?
A fixed layout ebook keeps each page exactly as designed, with the text locked in place beside the art. Picture books need this format because reflowable text would separate the words from the illustrations. You build it once, preview it on real devices and check every page before publishing.
The Bottom Line
A good picture book is a team effort between words, art and layout, tested out loud and proven in print. Choose your age band, plan your spreads, hire illustration help with a clear written agreement, build a careful fixed layout file and proof the physical book before you launch. Do those things in order and your small book will stand beside traditionally published titles on the shelf.
