Novel Format Manuscript: 2026 Complete Formatting Guide

TL;DR

A novel format manuscript follows specific standards: 12-point Times New Roman, 1-inch margins, double spacing, and left-aligned text on 8.5 × 11-inch pages. These specs apply to manuscripts submitted to agents and publishers. Book formatting for self-publishing is a separate process with different requirements for print and ebook. This guide covers both, term by term, so you can format correctly at every stage.

What “Novel Format Manuscript” Actually Means

The phrase “novel format manuscript” refers to the standardized way a novel’s text is prepared as a document, whether for submission to literary agents and publishers or as the starting point for self-publishing production. It is not the same as the interior design of a finished book sitting on a shelf.

This distinction trips up more writers than almost anything else. As one widely cited formatting resource puts it, manuscript pages “look very different from typeset book pages. Bereft of color and images and nice typography, manuscripts are stripped-down and homely and a paper-saver’s nightmare in their double-spaced sprawl.” That’s by design. The manuscript exists to be read and edited, not admired.

If you are preparing a novel manuscript for the first time, our manuscript preparation glossary walks through the broader pre-submission process. This page focuses on every formatting term you need to understand, with the actual specs that matter.

Quick-Reference: Manuscript Format vs. Book Format

Before diving into individual terms, here is the core comparison. These are the specs that apply to a standard novel format manuscript prepared for submission versus a self-published print book versus an ebook.

Element	Submission Manuscript	Self-Published Print Book	Ebook (EPUB)
Page size	8.5 × 11 in	Trim size (e.g., 5.5 × 8.5 or 6 × 9)	No fixed page
Font	Times New Roman or Courier, 12pt	Professional serif (Garamond, Palatino, etc.)	Relative sizing, reader-controlled
Margins	1 inch all sides	Varies by trim; gutter margin wider	CSS-based, not fixed
Line spacing	Double	Single or 1.15–1.3	Reflowable
Alignment	Left (ragged right)	Justified	Justified or left
Indent	0.5 inch first-line	0.2–0.3 inch first-line	CSS first-line indent
File format	.docx	Print-ready PDF	EPUB 3
Headers	Author name + title keyword + page number	Book title / chapter title + page number	None (device-controlled)

This table alone answers the question most new authors are actually asking. Now let’s define each term properly.

Glossary: Document Setup

Standard Manuscript Format

The baseline layout that agents, editors, and publishers expect when they receive a novel manuscript. It uses 8.5 × 11-inch pages, 1-inch margins on all sides, 12-point Times New Roman, and double spacing throughout. This format exists so that every submission looks the same, letting the writing speak for itself.

As William Shunn (whose formatting guide is the one more editors point to than any other) notes, “No one knows how many good stories are passed over because the manuscripts containing them are poorly formatted. We can be certain, however, that editors will more eagerly read a cleanly formatted manuscript than a cluttered and clumsy one.”

Practical tip: If you only remember one thing, remember this: standard manuscript format is about readability for industry professionals, not about making your document look like a published book.

Shunn Format

The most widely referenced manuscript formatting standard, created by Hugo and Nebula Award-nominated author William Shunn. Most publishers, including smaller presses, prefer or insist that writers follow Shunn’s guidelines. His checklist covers everything from contact info placement to page headers.

One practitioner on Substack argues that Shunn’s format is “archaic” and “perfect for paper submissions to agents and traditional publishers, especially if you’re typing them out on a manual typewriter,” but not ideal for the modern era of ebook readers. That critique has a point for self-publishing workflows, but for traditional submission, Shunn format remains the safest bet.

Font (Times New Roman / Courier)

The only two fonts universally accepted in novel format manuscript submissions are Times New Roman and Courier New, both at 12 points. Times New Roman is the more common choice today.

Why it matters: Decorative or unusual fonts signal to agents that the writer doesn’t know industry conventions. And Calibri, the default Microsoft Word font, is “one of the most reliable ways to make your book look immediately self-published” if it makes it into your final print file.

Practical tip: Set your font before you start writing. Changing it later can shift page counts and mess with headers.

Margins (1-Inch)

For a submission manuscript, use 1-inch margins on all four sides. No exceptions. This gives editors room for marginal notes and keeps the text block at a predictable width.

For self-published print books, margins change based on trim size and page count. The inside margin (called the gutter) must be wider because binding eats into it. A 6 × 9 book under 300 pages typically needs about a 0.75-inch outside margin and a 0.875-inch gutter. For detailed layout guidance, our book page layout guide covers margin math for every common trim size.

Double Spacing

Every line of a submission manuscript should be double-spaced. This convention dates back to typewriter days when editors marked corrections between lines. It persists because it’s genuinely easier to read long-form text with generous line spacing, and it gives beta readers and editors physical room to annotate.

Practical tip: Set double spacing in your paragraph styles, not by hitting Enter twice after every line. In Word, go to Format > Paragraph > Line Spacing > Double.

First-Line Indent

Each new paragraph in a novel format manuscript starts with a 0.5-inch indent. The first paragraph of a chapter or after a scene break is traditionally not indented (though some agents don’t care about this detail).

Common mistake: Using the Tab key to indent. Tabs create inconsistent spacing and cause problems when the file is converted for ebook or print production. Always set the indent through paragraph styles. If you are formatting dialogue-heavy scenes, our dialogue formatting guide explains how indents interact with quotation marks and attribution.

Left-Aligned / Ragged Right

Standard novel manuscript formatting uses left-aligned text, which means the right edge of each line falls wherever it naturally falls. This is called “ragged right.” Full justification (where both margins are straight) is not used in manuscripts because, as one widely cited agent explains, “you get big gaps between words in some lines of text that make it irritating to read.”

Published print books typically use justified text, but that justification is handled by professional typesetting software that can adjust letter and word spacing properly. Word’s justification algorithm is not nearly as good.

Paragraph Style

A saved set of formatting rules (font, size, spacing, indent, alignment) applied consistently to every paragraph in your document. Using paragraph styles instead of manual formatting is the single most important technical habit for manuscript formatting.

Why it matters: If you need to change your font from Times New Roman to Garamond for a print edition, paragraph styles let you change it everywhere in one click. Manual formatting means hunting through 300 pages.

Glossary: Page Elements

Title Page

The first page of a novel format manuscript. It includes your legal name and contact details (mailing address, phone, email) in the upper left corner, the approximate word count rounded to the nearest hundred in the upper right corner, and the title of your novel centered about one-third of the way down the page with your byline (pen name, if using one) just below it.

Your copyright page, which includes your ISBN number, is a separate element that appears only in published books, not in submission manuscripts.

Page Header / Running Header (Slugline)

Every page of a submission manuscript except the title page carries a header in the upper right corner. It contains a keyword from your title, your surname, and the page number. For example: DARKWOOD / Smith / 47.

This header (sometimes called a slugline or slug) ensures that if pages get separated or a digital file loses its formatting, every page can be identified. In published books, the running header usually shows the book title on left pages and the chapter title on right pages.

Word Count

On a submission manuscript, your word count goes in the upper right corner of the title page, rounded to the nearest hundred. A 73,482-word novel is listed as “approximately 73,500 words.”

The old rule of 250 words per manuscript page is obsolete. Modern practice uses the word processor’s count. For published books, words per page varies by trim size: a standard 6 × 9 trade paperback holds 250 to 300 words per page, while a mass market paperback (4.25 × 6.87) runs 300 to 350.

For guidance on how page numbers work in finished books, including Roman numerals for front matter, that’s a separate set of rules.

Glossary: Chapter and Scene Structure

Chapter Break

Each new chapter in a novel format manuscript starts on its own page. The chapter number and title (if any) are centered about one-third of the way down the page, typically in all caps. The body text begins four to six lines below. This visual breathing room signals a major narrative division.

Practical tip: Use Word’s “Page Break Before” paragraph setting rather than hitting Enter repeatedly to push text to a new page. Manual line breaks shift whenever you edit the preceding chapter.

Scene Break / Dinkus

A scene break marks a shift in time, location, or point of view within a chapter. In a novel format manuscript, the standard marker is three centered asterisks (* * *) or a hash mark (#). This marker is called a dinkus.

Why not just use a blank line? Because blank lines have a fatal flaw: they vanish at page boundaries. If a scene break falls at the exact top or bottom of a page, the reader sees the last paragraph of one scene at the bottom and the first paragraph of the next scene at the top with no visible gap. Practitioners on writing forums confirm this problem. One user shared their experience: “It can end up looking like a typo of a double space, as if someone hit ‘return’ too many times, and can be confusing.”

The dinkus solves this. Even if the break falls between pages, the asterisks on the new page tell the reader a scene shift has occurred.

Glossary: Front Matter and Back Matter

Front Matter

The pages that come before Chapter 1 in a published book. A typical novel needs five front-matter elements: half title (just the title, nothing else), full title page, copyright page, dedication, and optionally an epigraph or table of contents.

For ebooks, less is more. Front matter eats into Amazon’s “Look Inside” preview, which means potential buyers see your copyright page and dedication instead of your actual story. The practical advice from publishing professionals: move non-essentials to the back and let readers land near page one.

This front matter bloat problem is one of the most common self-publishing tells. Readers and reviewers notice.

Back Matter

Everything that follows the final chapter: acknowledgments, about the author, also-by page, discussion questions, glossary, or bonus content. For self-published authors, the also-by page is arguably the most valuable piece of back matter because it drives sell-through to your other titles.

Glossary: Production Formats and Specs

Manuscript Format vs. Book Format

This is the distinction that causes the most confusion. Manuscript formatting prepares a document for submission to an editor, publisher, or agent. Book formatting prepares a finished product for sale. A manuscript has double spacing, Times New Roman, and 1-inch margins. A published book has single spacing (or close to it), a professional interior font, justified text, and margins calibrated to its trim size.

They are entirely different stages of the same document’s life. You cannot submit a manuscript that looks like a book, and you should not publish a book that looks like a manuscript.

Trim Size

The physical dimensions of a finished print book. Common novel trim sizes include 5 × 8, 5.5 × 8.5, and 6 × 9 inches. Your choice of trim size affects margins, font size, words per page, page count, spine width, and printing cost.

A 70,000-word novel at 6 × 9 might run about 250 pages. The same text at 5 × 8 could push past 320 pages. This matters for pricing and reader expectations. Our Kindle formatting guide covers how these decisions interact with ebook production.

Gutter

The inner margin of a print book, the side closest to the spine. When pages are bound, some of this margin disappears into the fold. If your gutter is too small, readers have to crack the spine to read words near the binding.

Practitioners on Reddit’s r/selfpublish frequently flag this as the first formatting mistake new authors make. It’s invisible in a Word document or PDF viewed on screen, but painfully obvious in a physical copy.

EPUB / Reflowable Text

EPUB is the standard file format for ebooks. Unlike a PDF, an EPUB file has no fixed pages. Text reflows to fit whatever screen the reader uses, whether it’s a phone, a Kindle, or a tablet. Font size, line spacing, and margins are controlled by the reader’s device settings, not by the author.

This means you cannot design an ebook the way you design a print interior. Fixed layout elements, hard page breaks within chapters, and manual spacing all break in reflowable text.

Print-Ready PDF

The final file format submitted to print-on-demand services like IngramSpark or KDP Print. A print-ready PDF embeds all fonts, includes crop marks and bleed (if applicable), and matches the exact trim size of the finished book. It’s the last step before your novel becomes a physical object.

If you’re planning to publish through Amazon, our KDP publishing guide covers the upload process and file requirements.

Common Novel Format Manuscript Mistakes

These errors show up constantly in submissions and self-published books. Each one is easy to fix if you know to look for it.

Using Tab for indents. Tabs create inconsistent spacing and cause conversion nightmares. Set a 0.5-inch first-line indent in your paragraph styles instead.

Leaving Calibri as the body font. It’s Word’s default, and it screams “I didn’t format this.” Switch to Times New Roman for submissions. For print books, use a professional serif like Garamond, Palatino, or Baskerville.

Justified text in submissions. Agents expect left-aligned, ragged right. Justification in Word creates ugly word-spacing gaps.

Blank-line scene breaks without markers. Use a dinkus (three asterisks or a hash mark). Blank lines vanish at page boundaries.

Front matter bloat in ebooks. Every page of front matter before Chapter 1 reduces the “Look Inside” preview that sells your book. Keep it lean.

Ignoring the gutter. A print book needs a wider inside margin than outside margin. If you use 1-inch margins all around (the manuscript standard), text will be swallowed by the binding.

Manual formatting instead of styles. If you bold chapter titles by selecting text and clicking Bold 47 times instead of using a heading style, every global change becomes a nightmare. This also makes conversion to EPUB far more difficult.

Formatting Tools: A Brief Comparison

Tool	Price	Platform	Best For
Microsoft Word	Included with most PCs	Windows, Mac	Submission manuscripts (.docx is the standard agents expect)
Vellum	$249 (one-time)	Mac only	Self-published book interiors; widely considered the gold standard
Atticus	$147 (one-time)	Windows, Mac, browser	Cross-platform alternative to Vellum; most recommended option for Windows users
Adobe InDesign	~$23/month	Windows, Mac	Professional-grade typesetting; steep learning curve

For most authors writing a novel format manuscript for submission, Word is all you need. Formatting tools like Vellum and Atticus come into play when you’re converting that manuscript into a publishable book.

If the technical side feels overwhelming, Alpaca Authors handles formatting as part of its publishing packages, producing files that meet retailer specs for both print and ebook distribution.

The Formatting Workflow: Manuscript to Published Book

Understanding the full path helps explain why these terms matter.

Step 1: Write in standard manuscript format. Use the specs above. This is your working document and your submission document.

Step 2: Complete editing in manuscript format. Developmental editing, copyediting, and proofreading all happen on the double-spaced, Times New Roman manuscript. The formatting exists to make this process easier.

Step 3: Convert to book format. Once the text is final, you (or a formatter) convert the manuscript into a print-ready PDF and an EPUB. This is where trim size, gutter margins, justified text, professional fonts, and styled front matter come in.

Step 4: Upload and distribute. The print-ready PDF goes to your print-on-demand provider. The EPUB goes to ebook retailers. If you are going wide (selling on multiple platforms), our guide on publishing across platforms covers the logistics.

Authors who plan to produce audiobooks follow a parallel track. The manuscript (not the formatted book file) is what narrators and audio engineers work from. Alpaca Authors’ audiobook production service handles narrator casting, recording, mastering, and distribution to 45+ listening platforms.

FAQ

What font should a novel manuscript be in?

Times New Roman, 12 point. Courier New (12 point) is also acceptable, though less common today. These are the only two fonts universally accepted in standard manuscript format for submission to agents and publishers.

Is a novel manuscript double spaced?

Yes. Double spacing is required for all submission manuscripts. It gives editors room to annotate and makes long-form text easier to read. Single spacing is only used in the final published book format.

How do you format chapters in a novel manuscript?

Start each chapter on a new page. Center the chapter number (and title, if applicable) about one-third of the way down the page, in all caps. Begin the body text four to six lines below the chapter heading. Indent the first line of every paragraph 0.5 inches, except the first paragraph after the chapter heading.

What is the difference between a manuscript and a book?

A manuscript is the double-spaced, plainly formatted working document used for writing, editing, and submission. A book is the finished, designed product that readers hold or read on a device. Manuscript formatting prioritizes readability for editors. Book formatting prioritizes the reading experience for consumers.

What is Shunn format?

Shunn format is the most widely referenced standard for manuscript formatting, maintained by William Shunn. It specifies Times New Roman 12pt, 1-inch margins, double spacing, 0.5-inch first-line indents, left-aligned text, and specific placement rules for contact information, word count, title, and page headers.

Should I justify text in my novel manuscript?

No. Submission manuscripts should be left-aligned with a ragged right edge. Full justification creates uneven word spacing in Word and signals to agents that you’re unfamiliar with standard formatting. Justified text is appropriate only in the final typeset book.

What is a dinkus in a manuscript?

A dinkus is a set of three centered asterisks (* * *) or a hash mark (#) used to indicate a scene break within a chapter. It prevents the reader confusion that occurs when a blank-line break falls at a page boundary and becomes invisible.

How many words per page in a published novel?

It depends on trim size. A standard 6 × 9 trade paperback holds roughly 250 to 300 words per page. A mass market paperback (4.25 × 6.87 inches) fits 300 to 350 words per page. A double-spaced submission manuscript at 8.5 × 11 holds roughly 250 words per page, which is where the old estimation rule came from.
