Big Five Publishers Submission Guidelines (2026) 📚

You can submit to the Big Five publishers in 2026 — but almost every imprint requires a literary agent to do it for you.

In this guide, you’ll learn:

• The submission guidelines for each Big Five publisher and their major imprints
• Which rare imprints still accept unsolicited manuscripts directly from authors
• How to prepare your manuscript, query letter, and proposal for submission
• The step-by-step process from finished manuscript to book deal

Here’s exactly how submissions work at each publisher.

Who Are the Big Five Publishers?

The Big Five publishers are the five largest trade book publishing companies in the United States: Penguin Random House, HarperCollins, Simon & Schuster, Hachette Book Group, and Macmillan Publishers. Together, they publish the majority of bestselling books and control roughly 80% of the U.S. trade book market.

Each Big Five publisher operates through dozens (sometimes hundreds) of imprints — smaller publishing brands that specialize in specific genres, audiences, or formats. Understanding which imprint fits your book is more important than targeting the parent company.

Here’s what you need to know about submitting to each one.

Penguin Random House Submission Guidelines

Penguin Random House is the largest publisher in the world, with over 300 imprints and 70,000 titles published annually. Their imprints include Alfred A. Knopf, Doubleday, Viking, Putnam, Ballantine Books, Bantam, and Random House.

Submission policy: Penguin Random House does not accept unsolicited manuscripts. You need a literary agent to submit on your behalf.

The one exception: DAW Books, their science fiction and fantasy imprint, has historically accepted unsolicited submissions directly from authors. Check their current submission window before sending anything.

What they’re looking for:

• Fiction and nonfiction across virtually every genre
• Strong commercial or literary voice
• Completed manuscripts (fiction) or polished proposals with sample chapters (nonfiction)

How to submit: Work with a literary agent who has relationships with Penguin Random House editors. Your agent will target the specific imprint that best fits your book.

HarperCollins Submission Guidelines

HarperCollins publishes approximately 10,000 titles per year through 120+ imprints across 15 countries. Major imprints include Harper, William Morrow, Avon, Harlequin, HarperOne, and Ecco.

Submission policy: HarperCollins does not accept unsolicited submissions for most imprints. A literary agent is required.

Notable exceptions:

• Avon Impulse — HarperCollins’s digital-first romance imprint — has periodically opened to unagented submissions, particularly for romance in all subgenres
• Harlequin — acquired by HarperCollins in 2014 — accepts unsolicited manuscripts for specific romance lines through their online submission portal

What they’re looking for:

• Genre-specific manuscripts that match each imprint’s focus
• Fiction: completed, polished manuscripts
• Nonfiction: formal book proposals with platform evidence

How to submit: For most imprints, find a literary agent who represents your genre. For Harlequin romance lines, check their submission portal for current open calls.

Simon & Schuster Submission Guidelines

Simon & Schuster publishes around 2,000 titles annually through imprints including Atria Books, Scribner, Gallery Books, and Simon & Schuster Books for Young Readers.

Submission policy: Simon & Schuster does not accept unsolicited manuscripts. All submissions must come through a literary agent.

No current exceptions. Unlike some Big Five publishers, Simon & Schuster maintains a strict agented-only policy across all imprints.

What they’re looking for:

• Literary and commercial fiction
• Narrative nonfiction with strong platforms
• Young adult and children’s books (through their dedicated imprints)

How to submit: You’ll need an agent. Write a strong query letter and target agents who have sold books to Simon & Schuster imprints.

Hachette Book Group Submission Guidelines

Hachette Book Group publishes roughly 15,000 titles per year through over 200 imprints, including Little, Brown and Company, Grand Central Publishing, Orbit, and Forever.

Submission policy: Hachette does not accept unsolicited manuscripts for most imprints. Literary agent representation is required.

Notable exception: Orbit Books, Hachette’s science fiction and fantasy imprint, has occasionally accepted unsolicited submissions during specific open periods. Check their website for current status.

What they’re looking for:

• Strong genre fiction, especially through Grand Central Publishing and Forever (romance)
• Literary fiction through Little, Brown
• Science fiction and fantasy through Orbit
• Nonfiction with demonstrated author platform

How to submit: Work with an agent who targets Hachette editors. For Orbit, monitor their website and social media for open submission announcements.

Macmillan Publishers Submission Guidelines

Macmillan Publishers operates through major imprints including Farrar, Straus and Giroux, St. Martin’s Press, Henry Holt and Company, Flatiron Books, and Tor Publishing Group.

Submission policy: Macmillan does not accept unsolicited manuscripts for most imprints. Agent representation is required.

The major exception: Tor Books (and Tor.com Publishing), Macmillan’s science fiction and fantasy imprint, is one of the few Big Five imprints that has historically maintained open submission windows for unagented authors. Tor is arguably the most accessible Big Five imprint for writers without representation.

What they’re looking for:

• Literary fiction (Farrar, Straus and Giroux)
• Commercial fiction and nonfiction (St. Martin’s Press, Flatiron)
• Science fiction and fantasy (Tor — including novellas through Tor.com Publishing)

How to submit: For Tor, check their submission guidelines page for current open periods and format requirements. For all other imprints, you need a literary agent.

Big Five Imprints That Accept Unsolicited Submissions

Most Big Five imprints require agent representation. But a handful have historically accepted direct submissions from authors.

Important: Even imprints that accept unsolicited submissions may close their doors temporarily. Always check the imprint’s official website for current guidelines before submitting.

Notice a pattern? Science fiction, fantasy, and romance are the genres most likely to accept unagented submissions. If you write in other genres, you’ll almost certainly need an agent.

How to Prepare Your Manuscript for Big Five Submission

Whether you’re submitting through an agent or directly to an open imprint, your manuscript needs to meet professional standards. Here’s what to prepare.

Format Your Manuscript Correctly

Big Five publishers expect industry-standard manuscript formatting:

• Font: 12-point Times New Roman or Courier
• Spacing: Double-spaced throughout
• Margins: 1-inch margins on all sides
• Header: Your last name / title / page number in the upper right
• First page: Contact information, word count, and genre in the upper left

Don’t get creative with fonts, colors, or formatting. Editors want clean, readable pages.

Write a Query Letter That Gets Requests

Your query letter is the single most important document in the submission process. It’s the first thing agents and editors read, and it determines whether they’ll look at your manuscript.

A strong query letter includes:

• A hook that captures your book’s premise in 1-2 sentences
• A brief synopsis (250-300 words) that shows your story’s arc
• Comp titles that position your book in the market
• Your relevant credentials and platform

Study query letter examples that worked to understand what catches an agent’s attention.

Prepare a Book Proposal (Nonfiction)

If you’re submitting nonfiction, you need a full book proposal instead of a completed manuscript. A standard nonfiction proposal includes:

• Overview and hook
• Target audience analysis
• Competitive titles analysis
• Author platform and marketing plan
• Chapter-by-chapter outline
• 2-3 sample chapters

Publishers want to see that you have both expertise and an audience. Your platform — email list, social following, speaking career, media appearances — matters as much as your writing.

Write a Synopsis

Most agents and some imprints will request a synopsis — a complete summary of your book’s plot, including the ending. Keep it to 1-3 pages, single-spaced.

Your synopsis should cover major plot points, character arcs, and the resolution. Don’t leave cliffhangers — agents need to see that your story lands.

The Step-by-Step Path to a Big Five Book Deal

Getting published by one of the Big Five follows a predictable process. Here’s how it works from start to finish.

Step 1: Finish your manuscript. No publisher or agent wants to see an incomplete book (fiction). Finish it, revise it, and polish it until it’s the best you can make it. For nonfiction, complete your book proposal with sample chapters.

Step 2: Get feedback. Share your manuscript with beta readers or hire a developmental editor. Address structural issues, pacing problems, and character inconsistencies before querying.

Step 3: Research and query agents. Build a list of 20-50 agents who represent your genre. Personalize each query letter and follow each agent’s specific submission guidelines.

Step 4: Manage your submissions. Track every query you send — who you queried, when, and their response. Understand how long it takes to hear back from a literary agent (typically 4-12 weeks). You can send simultaneous submissions to agents unless they specifically say otherwise.

Step 5: Sign with an agent. When an agent offers representation, notify all other agents who have your manuscript. Your agent will help you revise further before submission.

Step 6: Go on submission. Your agent submits your manuscript to editors at Big Five imprints they believe are the right fit. This is the submission round, and it typically takes 2-6 months.

Step 7: Get a book deal. If an editor wants your book, they’ll make an offer. Your agent negotiates the advance, rights, and contract terms. Congratulations — you’re getting published.

How Long Does It Take to Get Published by a Big Five Publisher?

The timeline from finished manuscript to published book with a Big Five publisher typically takes 2-4 years. Here’s the breakdown:

• Querying agents: 3-12 months
• Revisions with agent: 1-6 months
• Submission to publishers: 2-6 months
• Contract negotiation: 1-3 months
• Editing and production: 12-18 months

That’s a long road. Many authors spend years in the query trenches before landing representation. And even with an agent, there’s no guarantee a publisher will buy your book.

If you want to publish faster without waiting years, self-publishing gives you complete control over your timeline. Tools like Chapter can help you write, edit, and format your manuscript for publication in weeks rather than years.

Do You Need a Literary Agent for the Big Five?

Yes — for the vast majority of Big Five imprints, you need a literary agent to submit your manuscript. Only a handful of imprints (primarily in science fiction, fantasy, and romance) accept unsolicited submissions directly.

A literary agent does more than just submit your book:

• They know which editors are looking for your type of book
• They negotiate your advance and contract terms
• They handle subsidiary rights (film, audio, foreign translation)
• They advocate for you throughout the publishing process

What If the Big Five Isn’t the Right Path?

Traditional publishing through the Big Five isn’t the only way to publish a book. In fact, many successful authors choose alternative paths.

Self-publishing gives you full creative control, higher royalty rates (up to 70% on Amazon KDP vs. 10-15% with traditional publishers), and a much faster timeline from manuscript to published book. Over 2,147 authors have used Chapter to write and publish their books, with some generating $13,200 from a single book or $60K in 48 hours.

Small and independent presses offer a middle ground — editorial support and distribution without the gatekeeping of the Big Five. Many accept unsolicited submissions directly.

Hybrid publishing combines elements of traditional and self-publishing, where you invest in production but receive publisher-level distribution.

The right path depends on your goals. If prestige, wide bookstore distribution, and a significant advance matter most, pursue the Big Five. If speed, control, and higher per-book earnings matter more, explore how to self-publish a book.

Common Mistakes When Submitting to Big Five Publishers

Avoid these pitfalls that sink submissions before editors even read your manuscript:

• Submitting without an agent to imprints that require one — your manuscript goes straight to the rejection pile
• Ignoring formatting guidelines — editors notice immediately when you haven’t followed standard manuscript formatting rules
• Querying before your manuscript is ready — first impressions matter, and you can’t resubmit to the same agent after a rejection
• Targeting the wrong imprint — sending literary fiction to a commercial imprint (or vice versa) signals you haven’t done your research
• Missing the genre fit — each imprint publishes specific genres, and sending a romance to a sci-fi imprint wastes everyone’s time
