A Crash Course in Submitting a Children's Book Manuscript

Finding the Right Publisher and Collecting Submission Guidelines

When you’re ready to share your children’s book with the world, the first step is to identify publishers who are looking for new titles. Don’t jump straight into a blanket email; take time to research and target the right fit. Start by consulting industry trade guides such as the Children’s Writer & Illustrator’s Market or Publishers Weekly’s Parent Section. These guides list dozens of publishers, their submission deadlines, and the specific types of manuscripts they accept. For a more current view, subscribe to newsletters like Children’s Book Insider, which features monthly updates on publisher needs and market trends.

Another effective tactic is to browse children’s sections in bookstores and libraries. Pick up a few books that are similar in theme, age group, or illustration style to yours. Note the publisher on the copyright page and search their website. Most publisher sites have a “Submission Guidelines” page that details exactly what they want. If you can’t find a submission policy online, don’t hesitate to send a short email or letter to the publisher’s editorial office. Attach a self‑addressed, stamped envelope (SASE) and ask for their guidelines. Because publishers receive many such requests, it may take a couple of weeks to get a response; meanwhile, you can keep refining your manuscript.

Once you have a list of potential publishers and their guidelines, review each one carefully. Pay special attention to word‑count limits, page limits, and whether they want a full manuscript or just a synopsis. Picture book publishers often require the entire manuscript, while some trade publishers prefer a query letter with a short sample. If a publisher specifically asks for a manuscript formatted on white paper with 1‑inch margins, double spacing, and paragraph indentation, obey those rules exactly. Inconsistent formatting can create a negative impression even if your story is strong.

When formatting a picture book manuscript, place your name and the book title at the top of each page. On the first page, list your contact information in the upper left corner: full name, street address, phone number, and email. Center the title about a third of the way down the page, leave a blank line, and begin the text. Avoid breaking the manuscript into “pages” that mimic the finished book layout; instead, keep it as a continuous document. Illustrations are generally not included unless you are a professional illustrator and the publisher specifically requests them. If you are an illustrator, consider sending a black‑and‑white dummy of each illustration along with 2–3 finished color sketches.

Make sure your manuscript is polished before you send it. Check for typographical errors, pacing issues, and language that might be confusing for your target age group. A clean, well‑formatted manuscript signals professionalism and respect for the editor’s time. Include a brief cover letter that states the title, intended age range, and word count. If you have prior publishing credits or are a member of a recognized writing organization, add those details, but only if they are relevant. If you are submitting to multiple publishers at once (simultaneous submissions), clearly state that in your cover letter and send a SASE so the editor can return your manuscript if needed.

Formatting Your Manuscript and Writing the Cover Letter

After you’ve settled on a publisher’s guidelines, it’s time to refine the final touches that will accompany your manuscript. The cover letter is your first conversation with an editor, and it should be concise, engaging, and tailored to the publisher’s interests. Begin with the editor’s name - if you can find it - followed by a short greeting. Then introduce yourself and the manuscript title. Mention the book’s target age range and total word count. A brief one‑sentence hook that captures the essence of the story can pique interest.

For picture books, the cover letter should not exceed a single paragraph beyond the basic facts. Editors of picture books rarely read full cover letters; they focus on whether the manuscript aligns with their current list and market demand. Include any relevant experience you have, such as previous book releases, writing workshops, or membership in the Society of Children's Book Writers and Illustrators. If you’re a first‑time writer, it’s acceptable to omit that section; honesty saves time for both parties.

When submitting fiction beyond picture books - especially middle grade or young adult titles - the editor will usually expect a query letter. A query letter follows a similar structure but includes a concise plot synopsis. In a few sentences, describe the main character, the central conflict, and the stakes involved. You should also mention the resolution or the direction the story takes. Maintain the same tone and voice as the manuscript, giving editors a feel for your narrative style. Keep the letter to one page; editors often skim multiple queries.

For nonfiction, a book proposal is often required. A proposal typically contains a brief overview of the book’s angle and tone, followed by a chapter‑by‑chapter outline. Each chapter description should be one or two sentences long, summarizing the key content. Attach the first two chapters if the publisher’s guidelines request them, and include a bibliography that lists the sources you consulted. In the cover letter, identify the target audience, provide an estimated manuscript length, explain what makes your book unique compared to other titles in the same niche, and highlight your expertise or credentials on the subject.

Never forget to attach a SASE in every submission. This simple envelope shows you respect the publisher’s time and makes it easy for them to return the manuscript if they are unable to consider it. If you’re sending a manuscript online, most publishers now accept PDF attachments; in that case, send a scanned PDF that preserves the formatting you used on paper. Some publishers may ask for a hard copy on white paper, so double‑check the requirements before you finalize your submission packet.

Navigating the Query Process, Book Proposals, and Follow‑Up

Once you’ve submitted your manuscript or proposal, the waiting game begins. Editors typically need several weeks - or sometimes months - to review submissions, especially if they receive a high volume. During this period, avoid sending follow‑up emails or letters until at least six to eight weeks have passed. A polite follow‑up can confirm receipt and remind the editor of your manuscript’s unique value. Keep the email short: restate the title, the manuscript type, and a brief reminder of the submission date.
