How do you write and edit your manuscript?
A children's book manuscript is shorter than you think. Picture books (ages 3-8) run 500 to 1,000 words. Early readers (ages 6-9) run 2,000 to 10,000 words. Middle grade (ages 8-12) runs 20,000 to 50,000 words. Word count discipline is non-negotiable — publishers reject manuscripts that run long because excess text competes with illustrations for page space.
Before you hire an illustrator or approach any publisher, your manuscript must be professionally edited. A developmental editor will assess story structure, pacing, age-appropriateness, and vocabulary level. A copy editor corrects grammar, punctuation, and consistency. Budget $500 to $1,500 for editing, depending on word count and complexity. Skipping this step is the most common reason children's book manuscripts get rejected.
Which age category and format should you choose?
Children's books are divided into strict age categories that determine page count, word count, trim size, and illustration density. Getting this wrong means your book sits in the wrong section at retail and reaches the wrong readers.
| Category | Age Range | Word Count | Pages | Standard Trim Size |
|---|---|---|---|---|
| Board Books | 0-3 | Under 100 | 12-24 | 6 x 6 in |
| Picture Books | 3-8 | 500-1,000 | 32 | 8.5 x 8.5 in |
| Early Readers | 6-9 | 2,000-10,000 | 48-64 | 6 x 9 in |
| Chapter Books | 7-10 | 10,000-30,000 | 80-150 | 5.5 x 8.5 in |
| Middle Grade | 8-12 | 20,000-50,000 | 150-350 | 5.5 x 8.5 in |
How do you hire a professional illustrator?
Illustration is the single largest cost and longest timeline item in children's book publishing. A 32-page picture book requires approximately 14 to 18 full-color spreads. A professional illustrator working in a style appropriate for commercial publishing charges $150 to $500 per illustration. Total illustration cost for a picture book typically runs $2,000 to $8,000.
Finding the right illustrator requires reviewing portfolios on platforms like Reedsy, Upwork, and the Society of Children's Book Writers and Illustrators (SCBWI) directory. Look for illustrators who have prior children's book credits and can demonstrate consistency across multiple pages — a single sample illustration tells you very little about how a full book will look.
Before signing any contract, confirm that you will own full commercial rights to the finished artwork. Work-for-hire agreements transfer all rights to you upon payment. Royalty-split arrangements are common with new illustrators but create long-term complications. Columbia Publication recommends work-for-hire for all self-publishing clients.
How do you format your book for print?
Children's books must be formatted as print-ready PDF files with specific bleed, margin, and resolution requirements. Amazon KDP requires 0.125 inch bleed on all sides and a minimum of 300 DPI for all images. IngramSpark has similar requirements but uses a slightly different template system.
Interior layout for a picture book is not something you can do in Microsoft Word. Professional layout software (Adobe InDesign, Affinity Publisher) is required to maintain image resolution, embed fonts correctly, and export color-managed PDFs. If you submit a low-resolution or improperly bled file, the printer will reject it. Formatting services for a picture book cost $300 to $800.
What is an ISBN and how do you get one?
An International Standard Book Number (ISBN) is required for distribution through any major retail channel. In the United States, ISBNs are purchased through Bowker. A single ISBN costs $125. A block of 10 costs $295. A block of 100 costs $575. If you plan to publish more than one book, buy the block of 10.
Amazon KDP offers a free ISBN, but this ISBN is Amazon-specific and cannot be used for IngramSpark, library distribution, or retail bookstore placement. Always purchase your own ISBN so you control your publishing imprint and can distribute through any channel.
Which distribution path should you choose?
Most independently published children's books use Amazon KDP combined with IngramSpark. Amazon KDP provides access to Amazon.com and Kindle. IngramSpark distributes to 40,000+ retailers and libraries globally, including Barnes and Noble, Book Depository, and independent bookstores.
Setting up both platforms takes 1 to 2 weeks. Amazon KDP approval is typically 24 to 72 hours. IngramSpark approval takes 5 to 7 business days. IngramSpark charges a $49 setup fee per title. Both platforms use print-on-demand, meaning no upfront print run is required.
How do you publish and market your children's book?
Once your book is live on Amazon and IngramSpark, your retail presence is established. Marketing determines whether anyone actually finds it. Children's book marketing focuses on school and library outreach, author visits, Amazon reviews, and targeted social media. An Amazon Author Central profile is free and critical — it connects your book to your author biography and other titles.
Request reviews from parents, teachers, and school librarians in your network before launch. Amazon requires a minimum number of verified reviews before its algorithm begins recommending your book to other readers. Aim for 10 to 25 reviews in the first 30 days.

What questions do first-time authors ask most often?
Publishing a children's book typically costs between $3,000 and $12,000 when working with a professional publisher. This covers illustration ($2,000-$8,000), editing ($500-$1,500), formatting ($300-$800), and distribution setup. Self-publishing on Amazon KDP costs as little as $0 upfront but requires you to fund illustrations separately, and the total still runs $1,000 to $3,000 minimum for a commercially viable picture book.
Publishing a children's book takes 6 to 18 months on average. Illustration is the longest stage at 3 to 6 months. Editing and layout take 4 to 8 weeks combined. Distribution setup on Amazon KDP and IngramSpark takes 1 to 2 weeks. Working with an experienced publisher like Columbia Publication reduces this timeline significantly through pre-vetted illustrators and streamlined formatting workflows.
Traditional publishers prefer to assign their own illustrators, so you should not hire one before submitting to traditional houses. For self-publishing, you must hire your own illustrator. Columbia Publication works with a curated network of professional children's book illustrators who understand age-appropriate art styles, commercial printing requirements, and bleed specifications.
The most common children's book trim sizes are 8.5 x 8.5 inches (square format for picture books), 8 x 10 inches (portrait picture books), and 6 x 9 inches (chapter books and early readers). Picture books for ages 3-8 typically run 32 pages. Early readers run 48-64 pages. Middle grade chapter books run 100-200 pages. Your distributor may have specific trim size requirements.
