Formatting for Print vs. Ebook

It’s important to distinguish between formatting for print and ebook versions, as they have different requirements:

Print Formatting

Print books require attention to details like trim size, margins (including gutter space for binding), page numbers, headers, and footers. The final output is typically a PDF file.

• Trim Size: KDP offers various trim sizes (e.g., 6×9 inches is common).
• Margins: Adequate margins are crucial for readability and binding. Mirror margins are often used for print.
• Bleed: If visual elements extend to the edge of the page, “bleed” must be enabled in the formatting settings.
• File Type: PDF is the standard for print uploads.

Ebook Formatting

Ebooks are “reflowable,” meaning the text adjusts to the reader’s device screen size. Formatting should be clean and simple, focusing on readability and navigation.

• Reflowable Text: Avoid fixed page breaks or elements that don’t adapt to different screen sizes.
• Table of Contents (TOC): A clickable TOC is essential for easy navigation.
• File Type: EPUB is the industry standard for ebooks, though KDP also accepts DOCX and KPF.
• No Page Numbers/Headers: These are unnecessary for ebooks.

Key Formatting Elements to Consider

Regardless of the software you choose, pay attention to these critical formatting elements:

Chapter Titles

Chapter titles should be clearly distinguished from body text, often using a larger font size, bolding, and centering or left-alignment. Consistency is key.

Paragraphs

Use first-line indents for paragraphs (except for the first paragraph of a chapter or after a scene break). Ensure consistent spacing between paragraphs.

Table of Contents (TOC)

A well-formatted, clickable TOC is vital for ebook navigation. Ensure your chapter titles are styled correctly (e.g., using Heading 1) to generate the TOC automatically.

Front and Back Matter

Include essential front matter like the title page, copyright page, and dedication. Back matter can include acknowledgments, an “About the Author” page, and other relevant content.

Images and Graphics

Ensure images are high-resolution and properly placed. Atticus, for example, automatically optimizes images for both print and ebook formats.

Conclusion: Choosing the Right Tool for Your Needs

The best KDP formatting software for you in 2025 depends on your budget, technical comfort level, and specific needs.

• For authors seeking an all-in-one solution with cross-platform compatibility and excellent value, Atticus is a top recommendation.
• If you are a Mac user prioritizing ease of use and a highly polished output, Vellum remains a strong contender, despite its higher cost and platform limitations.
• For authors on a budget or those already proficient with the software, Microsoft Word can be a viable option with careful attention to detail and the use of available guides.
• Kindle Create is a good free option for authors focused solely on the Amazon ecosystem.
