How to Format a Nonfiction Book in Word Before EPUB Conversion
Nonfiction manuscripts have different formatting demands than novels. Whether you're writing a self-help guide, business book, biography, or technical manual, the structure and visual hierarchy matter. Get it right in Word, and your EPUB conversion will be clean and professional. Get it wrong, and you'll spend hours troubleshooting formatting errors after conversion.
This guide walks you through the specific formatting considerations for nonfiction manuscripts before you convert to EPUB.
Why Nonfiction Formatting Is Different
Nonfiction readers expect clarity. They scan chapters for key points, jump between sections, and reference sidebars and callouts. Unlike fiction, where readers flow linearly through pages, nonfiction is often non-linear. That means your Word document needs to support that reading pattern.
The good news: most of the formatting work happens in Word, before any conversion tool touches your file. Tools like ebookconvert.pro will preserve your structure if you set it up correctly.
Step 1: Use Proper Heading Hierarchy
This is the foundation. Every nonfiction book needs a clear hierarchy: main chapters, subheadings, and sub-subheadings.
- Heading 1 = Chapter titles
- Heading 2 = Major section breaks within a chapter
- Heading 3 = Subsections (optional, only if needed)
- Normal/Body Text = Paragraph text
Do not use bold or larger font sizes to fake headings. Use Word's built-in Heading styles. When your document converts to EPUB, the conversion tool will recognize these semantic markers and create a proper table of contents automatically.
Pro tip: Use Heading 1 only for chapter titles. If your chapters don't have titles (just "Chapter 1," "Chapter 2"), create a Heading 1 with that label. This helps EPUB readers generate a navigable TOC.
Step 2: Format Sidebars and Callout Boxes
Nonfiction often includes sidebars—boxed text that highlights key ideas, case studies, or supplementary information. In Word, create these using a table with a single cell, or use a text box with a border and light background color.
Best approach: Use a single-cell table with a light gray or colored background. Apply a consistent border style. This survives EPUB conversion better than text boxes, which can break or lose formatting.
Add a title to each sidebar in bold, then the body text below. When you convert to EPUB, the table will render as a visually distinct block, maintaining the reader's sense of hierarchy.
Step 3: Handle Lists Correctly
Nonfiction relies on lists. Whether numbered steps, bullet points, or checklists, you must use Word's built-in list formatting—not manual dashes or asterisks.
- Numbered lists for sequential steps (e.g., "5 Steps to Build Your Audience")
- Bullet lists for non-sequential items
- Multilevel lists for complex hierarchies (e.g., main points with sub-points)
Go to Home → Paragraph → Bullets and Numbering. Choose your style and apply it to the entire list at once. This ensures consistent spacing and indentation, and it tells the EPUB converter that these are semantic lists, not just text with dashes.
Step 4: Manage Citations and Footnotes
If your nonfiction book includes citations, use Word's footnote or endnote feature—not manual superscript numbers.
Go to References → Insert Footnote (or Insert Endnote). Word will auto-number and manage placement. In EPUB, these convert cleanly and readers can tap to jump between the note and the reference point.
Decision point: Footnotes (at the bottom of the page) work better in print; endnotes (at the end of a chapter or book) work better in EPUB. Since you're targeting EPUB, use endnotes if your book is academic or heavily referenced.
Step 5: Format Emphasis and Special Text Carefully
Nonfiction often emphasizes key terms, definitions, or important statements. Use bold or italic sparingly and intentionally.
- Bold for key terms or definitions (e.g., "Conversion rate is the percentage of visitors who take a desired action")
- Italic for foreign words, book titles, or emphasis (e.g., "This is critical to understand")
- Avoid underlining — it's outdated and doesn't translate well to EPUB
- Avoid ALL CAPS for emphasis — use bold instead
Apply these styles using Word's formatting toolbar or Ctrl+B / Ctrl+I. Don't manually change font color or size to create emphasis; stick to semantic formatting.
Step 6: Insert and Caption Images and Charts
Nonfiction books often include graphs, charts, photos, or diagrams. Here's how to handle them:
- Insert images as PNG or JPG (300 DPI minimum for quality)
- Anchor them to text: Right-click → Wrap Text → In Line with Text. This ensures they stay with their surrounding paragraph in EPUB.
- Add captions: Right-click → Insert Caption. Use a consistent caption format (e.g., "Figure 1: Description of the chart")
- Size images reasonably: 4–6 inches wide is ideal for EPUB (which will reflow on different screen sizes)
Avoid floating images or text wrapping around images—these break in EPUB. Keep images inline and let them stack on their own lines.
Step 7: Create a Front Matter Section
Nonfiction books typically include front matter: title page, copyright page, dedication, table of contents, introduction. Set these up in Word before conversion.
- Title Page: Heading 1 style, centered, with book title and author name
- Copyright Page: Use Normal style, small font (10pt), left-aligned. Include publication date, ISBN, and copyright notice.
- Dedication: Optional, Heading 1 or a styled text block
- Table of Contents: Word can auto-generate this from your Heading 1 and Heading 2 styles. Go to References → Table of Contents → choose a style. (Note: When you convert to EPUB, the tool will create its own TOC, but having one in Word helps you verify your structure.)
- Introduction: Heading 1 for the title, then body text
Insert page breaks between each of these sections: Insert → Page Break. This keeps your structure clean.
Step 8: Avoid Common Nonfiction Formatting Mistakes
Here's what NOT to do:
- Don't use manual spacing: Don't press Enter multiple times to add space between sections. Use paragraph spacing instead (Paragraph menu → Spacing → Before/After).
- Don't use tabs for indentation: Use the Increase Indent button or set paragraph indentation (Paragraph menu → Indentation → First Line).
- Don't mix heading styles randomly: Stick to your hierarchy (Heading 1 → Heading 2 → Heading 3).
- Don't use text boxes for main content: Reserve text boxes for sidebars only, and use tables instead when possible.
- Don't embed fonts: While fonts can be embedded, EPUB readers often override them. Focus on semantic structure instead.
- Don't use columns: Multi-column layouts break in EPUB. Keep text single-column.
Step 9: Review and Validate Before Conversion
Before you convert to EPUB, do a final check:
- Run Word's spelling and grammar check (Review → Spelling & Grammar)
- Review your heading hierarchy: each Heading 1 should represent a major section, and Heading 2s should be subsections within those
- Check that all lists use Word's list formatting
- Verify that images are inline and properly captioned
- Confirm that footnotes/endnotes are in place and numbered correctly
- Test the auto-generated Table of Contents: does it accurately reflect your structure?
Once you're satisfied, save your file as .docx and you're ready to convert.
Converting Your Formatted Nonfiction Manuscript to EPUB
When your Word document is properly formatted, the conversion process is straightforward. Upload your .docx to a conversion tool like ebookconvert.pro, review the detected chapter structure, and generate your EPUB. The tool will preserve your headings, lists, sidebars, and images—because you've set them up semantically in Word.
The conversion tool will also auto-generate a table of contents from your Heading 1 and Heading 2 styles, so readers can navigate your book easily.
Final Thoughts
Formatting a nonfiction book in Word before EPUB conversion doesn't have to be complicated. The key is using Word's built-in styles and formatting tools—headings, lists, footnotes, captions—rather than trying to fake formatting with manual formatting. When you do that, your conversion to EPUB will be clean, readable, and professional.
Take the time to structure your manuscript properly in Word. Your readers will notice, and you'll save yourself hours of troubleshooting later.
