Understanding the Children’s Book Submission Process
Before you send your manuscript, it helps to know how children’s book submissions usually work. While each publisher follows its own guidelines, the process is generally simple and manageable when you prepare properly.
What Most Children’s Publishers Expect
- A polished manuscript or sample chapters.
- A short, clear cover letter introducing your book.
- A brief author bio highlighting your writing background.
- A summary or pitch explaining what makes your book unique.
- For illustrators: a portfolio or illustration samples.
Tips for Submitting Successfully
- Research the publisher to ensure your book fits their style and age category.
- Follow the guidelines carefully—this is often the biggest factor in getting noticed.
- Be patient, as response times can range from weeks to months.
- Be professional and concise in all communications.
- Keep writing and refining your craft while waiting for feedback.
How to Prepare a Strong Submission
An impressive submission package increases your chances with any publisher on the list. Here’s what to get right:
- State the age range clearly (picture book, 3–5; early reader, 6–8; middle grade, etc.).
- Add the word count and a one-sentence hook.
- Follow the publisher’s formatting instructions exactly.
- Keep your cover letter short, polite and professional.
- Proofread your manuscript thoroughly.
- If you’re an illustrator: include a curated 8–12 piece portfolio or 2–3 finished spreads.
Submission Etiquette & Practical Tips
Staying organised keeps the process smooth and stress-free.
- Track submissions with dates, publisher names, and response windows.
- Never attach large files unless requested — many houses prefer PDFs under a certain size.
- Avoid sending your manuscript to every publisher at once; choose the best matches.
- Consider entering open calls, competitions or mentorship programs — they’re effective for debut authors.
- Be patient; response times may take weeks or even months.
