Print Book Format Requirements
For KDP Print (paperback and hardcover), the requirements differ significantly:
Manuscript Preparation: Before You Format
Before diving into formatting, proper manuscript preparation saves hours of frustration later. Here's your pre-formatting checklist:
1. Complete Your Editing Process
Never format before your manuscript is completely edited. Every change you make after formatting may break your carefully crafted layout.
Essential editing stages:
2. Remove Manual Formatting
Manual formatting is the enemy of clean KDP conversion. Remove these common culprits:
Quick cleanup in Word: 1. Show formatting marks (Home > Show/Hide ¶) 2. Find & Replace: Search "^p^p^p" replace with "^p^p" (removes triple line breaks) 3. Find & Replace: Search " " (two spaces) replace with " " (one space) 4. Repeat until no instances found
3. Structure Your Document Properly
Proper document structure includes:
Ebook Formatting Best Practices
Now let's dive into the specific formatting requirements for creating a professional KDP ebook.
Typography and Text Formatting
Font selection: Amazon recommends sticking with standard fonts that render reliably across all devices:
Font sizes:
Paragraph formatting:
Chapter Formatting
Consistent chapter formatting creates a professional reading experience:
Chapter heading format: 1. Use Heading 1 style for chapter titles (critical for TOC generation) 2. Center or left-align chapter headings 3. Add space before (18-24pt) and after (12-18pt) chapter titles 4. Consider using bold or larger font size 5. Start chapters on a new page (Insert > Page Break)
Example chapter heading setup:
Scene Breaks and Separators
Scene breaks within chapters need clear visual indicators:
Important: Don't use multiple blank lines - ebook rendering can remove them, making scene breaks disappear.
Images and Graphics for Ebooks
Adding images requires careful attention to file specifications:
Image requirements:
Inserting images: 1. Place cursor where image should appear 2. Insert > Pictures 3. Select image, then Format Picture 4. Set text wrapping to "In Line with Text" 5. Resize proportionally (maintain aspect ratio) 6. Center the image (if desired)
Pro tip for children's books and graphic novels: Consider using Kindle Create tool specifically designed for heavy-image books.
Table of Contents (TOC)
A properly formatted TOC is essential for ebook navigation:
Automatic TOC creation: 1. Use Heading styles (Heading 1 for chapters) 2. Place cursor where TOC should appear 3. References > Table of Contents > Automatic Table 4. Right-click TOC > Update Field before publishing
Manual TOC (hyperlinked):
KDP automatically creates a navigation TOC from your heading styles, so proper heading usage is critical.
Print Book Formatting Essentials
Print formatting requires more precision than ebook formatting due to physical constraints.
Page Setup for KDP Print
Critical page settings:
1. Trim size selection - Most common: - 6" x 9" - Standard non-fiction, memoirs - 5.25" x 8" - Fiction, novels - 8.5" x 11" - Workbooks, textbooks
2. Margins - Vary by page count: - Inside margin (gutter): 0.375" to 0.875" - Outside margin: 0.25" to 0.5" - Top and bottom: 0.5" to 1"
Use KDP's margin guide (available when selecting trim size) to ensure proper binding clearance.
3. Headers and footers: - Running headers with book title/chapter name - Page numbers (typically outside corners or center bottom) - Leave first page of chapters header-free
Setting Up Mirror Margins
For professional print books, use mirror margins (different odd/even pages):
In Microsoft Word: 1. Layout > Margins > Custom Margins 2. Check "Mirror margins" 3. Set "Inside" margin larger than "Outside" (accounts for binding) 4. Apply to whole document
Managing Front Matter and Back Matter
Front matter standard order: 1. Blank page (for proper book opening) 2. Title page (odd-numbered page) 3. Copyright page (even-numbered page) 4. Dedication (odd-numbered page, optional) 5. Table of contents 6. Foreword/Introduction (if applicable)
Back matter: 1. Acknowledgments 2. About the author 3. Also by the author 4. Blank page (for proper book ending)
Page numbering: Front matter typically uses Roman numerals (i, ii, iii), while main content uses Arabic numerals (1, 2, 3).
Preparing Your Print PDF
Once formatting is complete, export your manuscript as a PDF:
PDF export settings: 1. File > Save As > PDF 2. Options > Optimize for: Standard (print quality) 3. Check "ISO 19005-1 compliant (PDF/A)" for archival quality 4. Ensure fonts are embedded 5. Save with descriptive filename
Always review your PDF before uploading to KDP. Check for:
