How to format a novel manuscript for publishing (2026)
From Word draft to publishable book: how to mark chapters and scene breaks, what a print interior needs (trim, margins, typography), ebook conversion, and the tools that do it — free and paid.
Editorial
There are two different things people mean by "formatting a manuscript": preparing a submission draft for agents (double-spaced, Times New Roman — a solved, boring problem), and turning a finished manuscript into a publishable book — a typeset print interior and a clean ebook. This guide is about the second, because it's the one self-publishers actually get stuck on.
Step 1: Mark your structure so tools (and humans) can read it
Book formatting starts from your manuscript's structure, so make it unambiguous:
- Chapters — either write them as their own line ("Chapter One", "Chapter 17: The Ledger", "Prologue") or style them with Word's Heading 1. Named chapters ("The Farm") work too when styled Heading 1.
- Scene breaks — a line containing only
***(or#) is the standard; two blank lines also read as a break in most tools. - Emphasis — use real italics, not underlines. Italics carry through to both editions; manuscript-era underlining does not.
That's the whole preparation. If your manuscript has these three conventions, every serious formatting tool can parse it.
Step 2: Know what the print interior needs
A print book is a different typographic object from a manuscript:
- an exact trim size (6×9″ standard for novels over ~60k words; 5×8″ for shorter fiction),
- mirrored margins with a gutter that grows with page count,
- a book face (Garamond, Caslon, and their lineages — not Calibri) at 10.5–12pt,
- justified, hyphenated text with widow/orphan control,
- trade conventions: chapters opening on right-hand pages, running heads (author left, title right) suppressed on openers, folios, unindented first paragraphs after openers and scene breaks.
None of this is subjective house style — it's the shared grammar of trade publishing, and readers subconsciously read its absence as "self-published."
Step 3: The ebook is structure, not looks
EPUB readers control fonts and sizes, so ebook formatting is about structure: one file per chapter, a working navigation table of contents, preserved italics, and valid EPUB3 packaging. The classic failure — an ebook that's one giant chapter — comes from converters that change the file format without detecting the chapters.
Step 4: Choose your tooling honestly
- Free — Reedsy Studio produces clean, standardized interiors at zero cost inside its ecosystem; Kindle Create is fine for basic Amazon-only ebooks (but its files don't work on other stores).
- Desktop, for volume — Vellum ($249, Mac-only) and Atticus ($147, cross-platform) are apps you learn; they pay off if you format many books and want deep control.
- Per book, instant — Ceeryo typesets directly from your Word file in the browser: chapters and scene breaks detected, a designed theme applied, and a KDP-preflighted print PDF plus EPUB downloaded in minutes.
The honest decision rule: many books + love of tinkering → buy desktop software; one finished manuscript and a launch date → use a per-book tool; zero budget and standard looks are fine → use the free options.
