Book Formatting Guide: From Manuscript to Published
A well-written book with bad formatting looks amateur. Inconsistent margins, random font changes, missing headers, broken table of contents: these problems signal to readers that the book wasn’t produced professionally, and that impression colors everything else they experience. Formatting is the difference between a manuscript and a book.
I’ve published 113+ books across Kindle, paperback, and hardcover. Formatting issues show up in every one of them at some stage, and catching them before publication is part of the production process. This guide covers the practical decisions you need to make and the common problems you need to avoid.
Key Formatting Elements
Margins: The space around your text needs to be wide enough for comfortable reading and narrow enough to avoid wasting pages. For print books, the inside margin (gutter) needs to be wider than the outside margin to account for the binding. A 6×9 book typically uses 0.75-inch outside margins and a 0.875-inch gutter, but this varies by page count and binding type.
Fonts: Serif fonts (Times New Roman, Garamond, Georgia) are standard for body text because they’re easier to read in long passages. Sans-serif fonts (Arial, Helvetica) work for headings and subheadings. Stick to 11 or 12 point for body text. Decorative or unusual fonts signal amateur production.
Text justification: Full justification (both edges aligned) is standard for print books. Left-aligned text is acceptable for ebooks since the reader’s device controls display. Avoid centered body text.
Headers and footers: Print books typically include the book title on left-hand pages, the chapter title on right-hand pages, and page numbers. First pages of chapters suppress the header. Getting this wrong is one of the most visible formatting errors.
Scene breaks: In fiction, use a blank line or a centered ornamental break (three asterisks, a small graphic) to indicate time or location changes within a chapter. Don’t rely on extra blank lines alone, because ebook formatting can collapse them.
Styles: Use paragraph styles in your word processor rather than manual formatting. Styles keep your formatting consistent throughout the manuscript and make global changes possible with a single adjustment. If you’re manually bolding every chapter heading instead of applying a heading style, you’re creating problems you’ll have to fix later.
Trim Sizes
The physical size of your print book affects its appearance, cost, and how readers perceive it. Common trim sizes and their typical uses:
6″ x 9″ is the standard for most novels and nonfiction. Large enough to read comfortably, small enough to be portable. This is the default choice unless you have a specific reason to go larger or smaller.
5.5″ x 8.5″ works for shorter novels, novellas, poetry, and compact nonfiction like self-help or travel books. More portable than 6×9.
5″ x 8″ is popular for genre fiction (mystery, romance) and memoir. A comfortable handheld size.
8.5″ x 11″ is standard for textbooks, workbooks, and manuals where you need space for diagrams, charts, or fill-in exercises.
8″ x 8″ or 7″ x 7″ (square formats) are used for children’s picture books, coffee table books, and image-heavy publications.
Larger trim sizes mean fewer pages for the same word count, which can reduce printing costs but increase shipping costs. Choose the size that matches your genre’s conventions and your readers’ expectations.
Platform-Specific Formatting
Different publishing platforms have different requirements. Getting these wrong causes rejection or display problems.
Kindle: Uses reflowable text, meaning the reader’s device controls font size, margins, and line spacing. Your formatting establishes the structure (headings, paragraphs, scene breaks, images) but not the exact appearance. Keep layouts simple. Use high-resolution images. Avoid text boxes, columns, or complex layouts that break on different screen sizes. The table of contents should use clickable links to chapters, not page numbers. Footnotes go to the back of the book, not the bottom of the page. Some front matter (dedication, epigraph) works better placed at the back for Kindle because readers sample the first pages and you want them reading content, not boilerplate.
Paperback: Requires fixed-layout formatting with specific attention to margins, gutters, bleed (if images extend to the edge), and spine width. Spine width depends on page count and paper type. The table of contents includes page numbers. Headers and footers display on printed pages. You control exactly how every page looks.
Hardcover: Same considerations as paperback, with the addition of dust jacket design (front cover, spine, back cover, interior flaps). The flaps provide additional space for your book description and author bio.
Always download and review a proof copy before approving a print book for distribution. What looks correct on screen often reveals problems in physical form.
Formatting Software
The right tool depends on your technical comfort, budget, and how much control you need.
Microsoft Word: Most widely available and familiar. Handles basic formatting (margins, styles, headers, page numbers) and is the accepted submission format for most publishing platforms. Limited for complex layouts. If you’re comfortable with Word, it’s sufficient for most books.
Vellum: The favorite among self-publishing authors for producing beautiful, professional results with minimal effort. Instant preview of your book across formats. Mac only. Not cheap, but the results justify the cost if you publish regularly.
Adobe InDesign: Professional-grade layout software used by publishers and designers. Maximum control over every element on every page. Steep learning curve and expensive. Worth it for image-heavy books, textbooks, or complex layouts. Overkill for a standard novel.
Scrivener: Excellent for writing and organizing large projects. Its compilation feature exports to multiple formats. Formatting output is adequate but not as polished as Vellum or InDesign. Better as a writing tool than a formatting tool.
Reedsy Book Editor: Free online tool for writing and formatting. Good for authors on a budget who need basic formatting. Requires internet connection and lacks advanced features.
Common Formatting Problems
These are the issues I see most frequently in manuscripts heading toward publication:
Missing or broken table of contents. Inconsistent heading styles (some chapters use Heading 1, others are manually formatted bold text). Incorrect or missing page numbers. Headers that appear on the first page of a chapter when they shouldn’t. Images that are too low-resolution for print (72 DPI images look fine on screen but print blurry; use 300 DPI minimum for print). Extra blank lines used as spacing instead of proper paragraph spacing settings. Different fonts appearing randomly because of copy-paste from multiple sources. Gutter margins too narrow, causing text to disappear into the binding.
Most of these problems are preventable by using styles consistently from the start and reviewing a physical proof before publication.
When to Hire a Professional Formatter
If your book has a straightforward layout (chapters of text, no complex graphics or tables), you can format it yourself with Word or Vellum and produce professional results. If your book includes complex elements (heavy illustration, charts, sidebars, multiple text styles, workbook layouts), hiring a professional formatter or typesetter is worth the investment. The cost typically ranges from $500 to $2,000 depending on complexity and length.
