Submitting a children’s book manuscript to a publisher may seem intimidating, especially if it’s your first time navigating the publishing world. But once you understand the steps, the process becomes much more manageable. Whether you’ve written a picture book, an early reader, or a full middle-grade novel, the key is to prepare your manuscript professionally, research the right publishers, and follow their submission guidelines carefully. This guide breaks down everything you need to know so you can approach the submission process with confidence and give your story the best chance of being published.
1. Know what kind of children’s book you’ve written
Children’s publishing is diverse and genre-specific. Before you submit, be clear about where your book belongs.
- Picture book (ages 0–7): Usually 24–48 pages; text is often succinct and picture-driven. Many picture-book authors submit text-only manuscripts (the publisher pairs the text with an illustrator).
- Early readers / chapter book (ages 5–8): Short chapters, simple vocabulary, often 1,000–10,000 words.
- Middle grade (ages 8–12): Strong character focus, plots that fit younger readers, roughly 20,000–50,000+ words.
- Young adult (ages 13+): Older protagonists, more complex themes, longer length (50,000–90,000+ words).
Knowing your category informs word count expectations, tone, and where you should submit.
2. Perfect the manuscript before you submit
Publishers expect polished work. Submitting a first draft drastically lowers your chances.
- Revise for clarity and voice: Tighten language, clarify motivation, and make sure the emotional arc works for your target age.
- Focus on pacing: Picture books need a strong beginning, an engaging middle, and a satisfying ending within very few words. Novels need scenes that move the plot and develop characters.
- Read aloud: For picture books especially, rhythm and read-aloud quality matter. Read to children in your target age-range if possible or imagine how an adult would read the text aloud.
- Line-edit and proofread: Typos and messy grammar make a bad first impression.
- Beta readers: Get feedback from teachers, librarians, parents, or critique groups. Take criticism seriously and revise.
3. Format the manuscript professionally
Formatting is simple but important. If the editor can’t easily read your manuscript, they may not read it.
- Use a standard font and size: e.g., Times New Roman or Arial, 12 pt.
- Double-space for prose submissions; single-spaced is sometimes acceptable for picture-book text but double-spacing is safe.
- Include page headers: Title and your last name or contact info on the top of each page.
- Number pages consistently.
- Scene breaks: Use a centered symbol like “***” or a blank line.
- For picture books: Present text as a continuous manuscript (not mock-up spreads) unless the publisher requests a storyboard format.
Always check a publisher’s submission guidelines for any specific formatting they require.
4. Prepare submission materials
Most publishers ask for a package beyond the manuscript. Typical materials include:
- Cover letter / query letter: One page. State the book’s title, target age range, word count, a one- or two-line hook, and a brief author bio (relevant publications, credentials, or experience). Keep it professional and concise.
- Synopsis: For longer works (middle grade and YA), prepare a 1–2 page synopsis that summarizes the whole plot, including the ending. For picture books, a brief paragraph synopsis (2–4 sentences) is usually enough unless a publisher asks for more.
- Full manuscript or sample chapters: Follow the publisher’s guidance — some want full manuscripts for picture books and middle grade; others want only the first three chapters for novels.
- Illustrations: If you are also the illustrator and the publisher accepts author-illustrator submissions, include samples of your artwork in the format requested. If you are not the illustrator, do not send mock-up illustrations unless asked.
- Marketing blurb / pitch: A short paragraph describing why kids will love the book and where it fits in the market.
- Author bio: Short and relevant — highlight publications, teaching experience, awards, or relevant expertise.
5. Research publishers carefully
Not every publisher accepts every kind of submission. Targeting appropriate publishers increases your odds.
- Children’s imprints: Large houses often have specific imprints for different age groups; look for imprints that publish similar books to yours.
- Submission windows: Some publishers open for unsolicited submissions only at certain times; others accept year-round through an agent.
- Guidelines: Read each publisher’s submission guidelines carefully — they will tell you what to send, how to send it (email vs. portal vs. postal), and whether they accept unsolicited work.
- Editor names: If the guidelines ask for a query to a specific editor, follow that instruction precisely.
6. Decide whether to submit directly or seek an agent
- No agent: Many small and independent publishers accept unsolicited manuscripts from authors. If you submit directly, follow their guidelines exactly.
- With an agent: Larger publishing houses typically require submissions through an agent. Agents can negotiate better advances and contracts, but they also take a commission. If your manuscript is literary, commercial, or high-concept and you want broader reach, consider querying agents first.
7. Submit carefully and professionally
- Follow instructions exactly: If a publisher asks for attachments as PDFs, don’t send Word docs. If they want the manuscript pasted into the email body, don’t attach files.
- Personalize queries: If a submission form asks why you chose this publisher, explain briefly and specifically.
- Keep track: Maintain a spreadsheet that records publisher name, submission date, materials sent, response time, and outcome.
8. Understand rights and contracts (basic primer)
You won’t negotiate these until (and unless) you receive an offer, but it helps to know the basics.
- Exclusive vs. nonexclusive rights: Publishers typically ask for certain exclusive rights for a term. Know what rights you value (e.g., foreign, audio, digital).
- Illustration rights: For picture books, clarify whether the publisher will hire the illustrator or use your illustrations.
- Advance and royalties: New authors often receive modest advances and standard royalty splits. An agent can help negotiate better terms.
- Subsidiary rights: These include audio, translation, TV/film — these are valuable and often negotiated separately.
If you don’t understand a contract, consult a publishing lawyer or agent before signing.
9. Handle rejections and revisions professionally
Rejection is normal. Even excellent manuscripts are rejected for reasons unrelated to quality (timing, list fit, editorial direction).
- Be resilient: Expect “no” more times than “yes.” Use feedback where offered.
- Revise and resubmit: If multiple rejections point to the same issue, revisit and revise the manuscript.
- Personalize future submissions: If feedback suggests your book is a better fit elsewhere, adjust your list accordingly.
10. When you get interest: next steps
If an editor requests a full manuscript or offers representation, respond professionally and promptly.
- Provide requested materials quickly: Editors often request additional materials; meet their timelines.
- Ask questions: Clarify schedule, editorial process, and expectations.
- Negotiate if necessary: If you’re offered a contract and don’t understand terms, seek professional help.
11. Tips specific to picture books
- Keep it short and lean: Many picture-book manuscripts are under 800 words; some under 400. Every word must earn its place.
- Show, don’t tell: Let illustrations carry part of the storytelling; avoid over-describing visuals layer-by-layer in the manuscript.
- Avoid didactic endings: Celebrate emotional payoff over preaching.
- Test with children: See how kids react to rhythm, humor, and pacing.
12. Tips for middle grade and YA submissions
- Voice matters: A compelling, authentic narrator carries the story.
- Character-driven plots: Middle grade readers connect with character choices and consequences.
- Hook early: Get readers invested by the end of the first chapter.
- Age-appropriate themes: Tackle big ideas through age-appropriate lenses.
13. Etiquette: simultaneous submissions and follow-ups
- Simultaneous submissions: Many editors accept simultaneous submissions (where you submit to multiple publishers at once), but disclose it if the guidelines request it. If one publisher requests an exclusive and you don’t want to wait for others, weigh the offer carefully.
- Follow-up: If a publisher’s stated response time has passed, a polite email inquiry is acceptable. Keep it short and respectful.
14. Keep learning and connecting
- Attend conferences and workshops: These are great for meeting editors, agents, and other authors.
- Join critique groups and local writing communities: Constructive critique leads to stronger manuscripts.
- Read current children’s books: Understand market trends without writing to trends. Knowing what’s out there helps you pitch your book accurately.
15. Submission checklist (quick)
- Manuscript thoroughly revised and proofread
- Correct formatting and page numbering
- One-page query/cover letter
- Two-page synopsis (for novels) or short synopsis for picture books
- Sample chapters or full manuscript as requested
- Author bio and marketing blurb
- List of targeted publishers and submission dates
- Spreadsheet tracking submissions and responses
Conclusion
