What Is Ebook Formatting? — Self-Publishing Glossary
Ebook Formatting: Ebook formatting is the process of converting a manuscript (typically a Word or Google Docs file) into a properly-structured ebook file (ePub or MOBI/KFX) with correct typography, chapter structure, table of contents, and styling for display on e-readers and reading apps.
Ebook formatting is the step between “I finished writing my book” and “my book is live on Amazon.” It’s also the step most first-time indie authors underestimate — or skip entirely.
What Ebook Formatting Actually Involves
Your manuscript in Word is a text document. An ebook is a structured software package (an ePub file) that e-readers interpret and display. Converting between these requires more than renaming a file:
Structural conversion: Your manuscript’s chapter breaks, section breaks, and heading hierarchy need to be correctly mapped to ePub’s HTML structure. Chapter titles become H1 tags. Section breaks become scene-break elements. Body text becomes paragraph elements with correct CSS styling.
Typography: The font, size, spacing, and drop cap implementation are defined in CSS stylesheets embedded in the ePub. These need to be written correctly to render consistently across Kindle, Kobo, Apple Books, and other readers.
Table of Contents: Ebook TOCs are functional navigation elements — readers tap a chapter title and jump directly there. These must be programmatically generated from the book’s heading structure, not manually typed.
Metadata: Title, author, language, and description need to be correctly embedded in the ePub’s metadata for it to display correctly on retailer pages.
Validation: A properly formatted ePub passes ePub validation standards. Invalid ePub files can display incorrectly or be rejected by retailers.
Formatting Tools Compared

|---|---|---|---|---|
| Vellum | $199–249 | Mac only | Excellent | Mac authors, quality-first |

The Vellum Standard
Vellum is the industry standard for indie ebook formatting. Open any bestselling indie novel in your preferred genre on Amazon — the sample will almost certainly show Vellum formatting. The consistent quality of Vellum’s output has established it as the benchmark readers and retailers expect.
The problem: it costs $199 and only runs on Mac.
MekarPad exists to solve that problem — professional Vellum formatting delivered to any author, on any platform, at $75/book.
Common Mistakes
Treating manuscript formatting (in Word) as ebook formatting — how your book looks in Word has almost nothing to do with how it will look on a Kindle. These are different problems.
Using Word's 'Save as ePub' and calling it formatted — Word's ePub export is technically a valid file but produces messy code that renders poorly on many devices.
Formatting-by-eye in Word (manual bold, manual font sizes) instead of using Word's built-in heading styles — manual formatting doesn't transfer to ePub. Heading 1, Heading 2, Normal styles do.
Skipping the preview step — always preview your formatted ebook on an actual Kindle device or the Kindle Previewer app before publishing. What looks right in Calibre may look wrong on a real device.
MekarPad provides professional ebook formatting using Vellum — the industry-standard formatting software — starting at $75 per book.

What's the difference between formatting a manuscript and formatting an ebook?
Manuscript formatting is for human readers (editors, agents, beta readers) — typically Times New Roman, double-spaced, 1-inch margins, following standard submission guidelines. Ebook formatting is for e-readers and reading apps — it involves converting the manuscript into an ePub file with correct HTML structure, embedded fonts, a functional table of contents, and styling that renders correctly across all devices.
Can I format my own ebook?
Yes. The main tools are Vellum ($199, Mac only), Atticus ($147, Mac/Windows/Web), and the free Reedsy Book Editor. Each has a learning curve. Vellum is the easiest to learn and produces the best output. For authors who don't want to learn formatting software, a professional formatting service (like MekarPad, from $75) handles it for you.
How long does ebook formatting take?
DIY in Vellum: 2–4 hours for a standard novel once you've learned the software. Professional formatting service: 3–5 business days turnaround. The timeline for a service is longer because there's coordination involved, but you get professional results without learning new software.
What file do I need to submit for ebook formatting?
A Microsoft Word .docx file is the standard input for most formatting services and tools. Google Docs can be exported to .docx. Scrivener can compile to .docx. The file should use Word's built-in heading styles (Heading 1 for chapter titles, Normal for body text) rather than manual formatting for best results.
