How Fiction Authors Format Books for Print and Ebook

Book formatting is the invisible craft of publishing: when it is done well, readers notice nothing; when it is done badly, readers notice everything. Inconsistent chapter headers, inappropriate fonts, missing front matter, and poor ebook reflowability all generate reviews that describe the reading experience as amateurish regardless of the writing quality. This guide covers the formatting decisions that matter most for fiction — both ebook and print — and what readers and retailers actually expect.

Ebook Formatting Fundamentals

Ebooks reflow text to fit any screen, which means fixed layouts that look good on one device can break on another. Use styles-based formatting (not manual spacing) in your word processor so that heading levels, paragraph indents, and chapter breaks translate correctly to ebook formats. Never use tabs or multiple spaces for paragraph indentation — use a style with a first-line indent set to 0.3 inches. Never use multiple line breaks to create visual spacing — use paragraph spacing styles. These rules exist because ebook conversion programs (Calibre, Vellum, Atticus) translate styles correctly but often misinterpret manual formatting.

Print Trim Sizes and Their Trade-offs

The most common trim sizes for trade paperback fiction are 5x8 inches and 5.5x8.5 inches. A 5x8 trim with 11pt Times New Roman body text and standard margins produces approximately 250 words per page; a 90,000-word novel will run approximately 360 pages. Wider trim sizes fit more words per page and reduce page count, which reduces printing cost and increases royalties per unit. But wider books look different from the standard trade paperback your readers know — and in some genres, looking like a standard trade paperback is part of the professional signal. Know your genre's conventions before choosing a trim size.

Fonts and Their Genre Signals

Font choices signal genre before a reader opens the book. Garamond and Palatino read as literary or historical. Times New Roman and Georgia read as standard commercial fiction. Baskerville reads as slightly more elegant. Helvetica and other sans-serif fonts read as contemporary or thriller when used for body text. Mixing a serif body font with a complementary sans-serif for chapter headers is standard practice. Avoid fonts that your readers will not have installed on their devices (for ebooks) or that do not embed cleanly (for print). Lora, a serif font available through Google Fonts, works well for ebook body text and embeds cleanly in print PDF.

Chapter Headers and Scene Breaks

Chapter headers establish visual rhythm and professional presentation. The chapter number and chapter title (if you use both) should be styled consistently throughout — same font, same size, same spacing above and below. Scene breaks within chapters should use a consistent separator: three asterisks, a centered em-dash, or a decorative element that matches your cover's aesthetic. Do not use blank lines alone as scene breaks — ebook conversion programs sometimes eliminate extra blank lines, making scene breaks invisible to readers. A styled separator preserves the break across formats.

Front and Back Matter

Front matter (everything before chapter one) should include: title page, copyright page, dedication (optional), and table of contents (for ebooks, linked; for print, page-numbered). Back matter (everything after the final chapter) should include: acknowledgments, author's note if relevant, about the author, and links or descriptions of other books. Back matter is where readers who finished your book and want more go immediately — it is your most valuable real estate for capturing newsletter subscribers and selling your next book. Make it easy to find and easy to act on.

Tools for Self-Formatting

Vellum (Mac only) produces the most polished ebook and print output of any consumer formatting tool, with templates that look genuinely professional. Atticus (cross-platform) is a strong alternative with an active development team. Scrivener can produce acceptable ebook output with careful setup but requires significant configuration. Word or Google Docs exports can be used as inputs to these tools. The cost of a formatting tool ($100-$200) is recovered in avoided formatting errors and time savings within the first book. Hiring a professional formatter ($50-$200 per book) is reasonable for authors who find the tools difficult and publish infrequently.

Frequently Asked Questions

Should I format my own books or hire a formatter?

If you publish more than two books per year, learning a formatting tool pays for itself quickly. If you publish one book per year or fewer, hiring a formatter and spending your time writing is the better allocation. The exception: if formatting errors in your early work have generated reader complaints, fixing those errors is worth the time investment regardless of frequency.

What margin settings should I use for print?

For a 5x8 trim, use: top 0.75 inches, bottom 0.75 inches, inside (gutter) 0.875 inches, outside 0.5 inches. These are conservative settings that work for most page counts. For books over 400 pages, increase the gutter to 1 inch to prevent text from disappearing into the spine.

Do I need a different file for ebook and print?

Yes. Ebooks require EPUB or MOBI format; print requires a PDF with embedded fonts and bleed settings if your cover extends to the page edge. Formatting tools like Vellum and Atticus export both from the same project file, which is the main efficiency advantage of using them.

What is widow and orphan control?

Widows are single lines of a paragraph that appear at the top of a page; orphans are single lines that appear at the bottom. Both look unprofessional and distract readers. Word processors and formatting tools have widow/orphan control settings that automatically adjust page breaks to eliminate them. Enable this setting for print formatting.

How do I format a series consistently?

Create a master style template for your series — fonts, sizes, header styles, margin settings — and apply it to each new book. Store the template file separately from your manuscripts and use it as the starting point for each new title. Consistent formatting across a series is a professional signal that readers notice even if they cannot articulate what they are seeing.
