Must Follow Amazon Book Publishing Requirements and Kindle Guidelines For 2025

Publishing on Amazon is not about guessing rules. It is about following clear steps that help your book pass checks, load fast, and stay live. When you meet Amazon book publishing requirements, your Kindle and print editions open cleanly, display well, and reach more readers.

This guide gives you every rule in one place. You will learn how to prepare your Kindle file, format your print interior, design your cover, and use the right categories and keywords. It also explains accessibility and layout choices for children’s books, so your files look professional everywhere.

Each part comes with expert notes, examples, and ready-to-use checklists built for 2025 publishing standards.

Prepared by Estorytellers, a US-based publishing team that has supported over 200 successful Kindle and print book launches. The team includes experts in compliance, digital production, print layout, design, accessibility, and children’s content.

KDP Content Rules: What’s Allowed and What Can Get You Taken Down

Core Policy Pillars

Amazon’s content guidelines are very clear. Before you upload a book, you must confirm that every part of your file belongs to you or is licensed properly. That includes text, images, fonts, and data. If something in your book comes from another creator, keep a written record of permission or license proof. This protects your account and avoids policy violations later.

Metadata honesty matters just as much. Avoid using competitor names, trending brands, or irrelevant words in your title or subtitle. Misleading series claims or overstuffed keywords are common reasons for rejection. Each word in your metadata should help readers find your book for the right reasons.

Sensitive or regulated content is another key area. KDP reviews all books for accuracy, age suitability, and regional compliance. Make sure children’s books are marked correctly with the right age and reading level. For nonfiction or educational works, review factual claims before uploading.

Before-You-Upload Compliance Pass

Before you hit “Publish,” walk through one clean pass of your entire file. Check the following:

• Proof of Rights and Permissions: Keep digital copies of all licenses and permissions.
  
• Disclaimer Language: Add appropriate disclaimers for medical, financial, or advice-based books.
  
• Clean Front and Back Matter: No deceptive endorsements or unrelated links.
  
• Subtitle and Series Accuracy: Match the title and subtitle exactly across Kindle and print.

This step prevents your book from being flagged, delayed, or suspended after going live.

Compliance Lead: “Most takedowns come from metadata issues. If your title and permissions are clean, your book stays live.”

 KDP Content Compliance Checklist

Section	Item	Status	Notes
Rights & Permissions	Proof of ownership or license for all text/images/fonts	✅ / ❌	Upload permission emails or license files
Metadata	Title/subtitle accuracy	✅ / ❌	Must match across Kindle and print
Metadata	Series naming consistency	✅ / ❌	Avoid misleading numbering or false series claims
Description	Honest and accurate	✅ / ❌	No keyword stuffing or misleading promises
Keywords	Relevance and appropriateness	✅ / ❌	Only use terms that match book content
Sensitive Content	Age/Category appropriateness	✅ / ❌	Check children’s rating, regulated topics
Disclaimers	Required legal or factual disclaimers	✅ / ❌	E.g., medical advice, financial guidance
Front/Back Matter	Clean and non-deceptive	✅ / ❌	Remove unrelated links or misleading info

This checklist keeps you aligned with current Amazon book publishing requirements and makes future uploads faster.

Case Study: A Flagged Memoir That Got Cleared

A US author published a personal memoir that was briefly flagged for “potential trademark misuse.” The issue came from a tagline in the subtitle that matched a registered slogan. After working with Estorytellers, the author submitted proof of original writing and permission emails for quoted content. The subtitle was updated, and the memoir was restored within 48 hours. The clean metadata now helps the book maintain a consistent ranking without further review.

Kindle File Prep: Reflowable EPUB vs Fixed-Layout

Choose the Right Format

Most text-heavy books, like nonfiction or fiction, should use reflowable EPUB. This format adapts to different screen sizes and keeps the file size small. Fixed layout is best for picture books, illustrated guides, or complex textbooks. Choosing the correct format prevents formatting issues on Kindle devices and apps.

Technical Must-Haves

• Valid Table of Contents: Ensure all headings link correctly.
  
• Semantic Headings: Use H1, H2, H3 tags for structure.
  
• Embedded Licensed Fonts: Avoid missing fonts or substitutions.
  
• Optimized Images/DPI: Compress without losing quality; high DPI for illustrations, moderate for text.
  
• Footnotes/Endnotes: Verify links and pagination.
  
• Testing: Preview on multiple devices to check TOC, line breaks, and overflow issues.

Best Practices

• Always validate EPUB files before upload.
  
• Fix warnings or errors flagged by Kindle Previewer.
  
• Reflowable format improves accessibility, making text scalable for visually impaired readers.

Print Interiors: Specs that Pass on the First Try 

Layout Fundamentals

Correct print interiors are crucial for Amazon book publishing requirements and professional presentation. Key considerations include:

• Trim Sizes: Common options are 5×8, 5.5×8.5, 6×9 inches. Select based on genre, page count, and reader expectations.
  
• Margins and Gutters: Ensure proper space for binding; adjust for page count and trim size.
  
• Running Heads / Folios: Include book title, author name, and page numbers consistently.
  
• Hyphenation and Orphans/Widows: Avoid awkward breaks and maintain clean paragraphs.
  
• Image Placement: Ensure alignment, resolution, and bleed as needed.
  
• Export Format: PDF/X is preferred; keep grayscale or color as intended; use rich black for sharper text.

Proof Discipline

• Always order a print proof before final submission.
  
• Review trim tolerance, line breaks, image contrast, and figure captions.
  
• Confirm page count matches spine calculation to prevent misaligned covers.

Cover Wraps & Thumbnails: Design to Spec 

Wrap Requirements

Covers are the first impression for readers, so meeting Amazon book publishing requirements is critical. Key specifications:

• KDP Templates: Use official KDP cover templates to ensure spine and wrap alignment.
  
• Spine Calculation: Adjust for final page count; incorrect spine causes misprints.
  
• Barcode and Price Box: Place in recommended location; avoid overlapping with text or images.
  
• Finish Options: Matte or glossy, depending on genre and preference.
  
• Type Size: Avoid tiny fonts; ensure legibility on physical book and thumbnail images.
  

Thumbnail Readability

Thumbnails are often the first thing readers see on Kindle or Amazon product pages. Consider:

• Single Focal Element: Ensure the main visual is clear even at 120 px width.
  
• Title and Subtitle Contrast: Strong contrast ensures readability on devices.
  
• Series Branding: Consistent design across books in a series improves recognition.
  
• Avoid Text in A+ Images: Text baked into A+ images may not scale properly on thumbnails.

Quote

Estorytellers Design Lead: “If your title isn’t readable at 120 px, it isn’t readable.”

Cover Wrap Spec Template

Element	Requirement	Notes / Tips
Front / Spine / Back Layers	Separate layers in PSD/AI/PSB	Keep editable
Safe / Trim / Bleed Guides	Maintain at least 0.125 in safety margin	Prevent clipping
Barcode Placement	Bottom right of back cover	Do not overlap text or images
Minimum Type Size	12 pt for body text, larger for title	Ensure legibility in print and thumbnail
Contrast & Readability	Strong contrast between text & background	Especially for thumbnails

Mini Case

Author Testimonial

A business nonfiction author said, “We stopped ping-ponging edits when we used one signed checklist. Uploads passed KDP without a single issue.”

Categories, Keywords & Browse Paths: Visibility Without Stuffing 

Map BISAC to Amazon Browse Nodes

Choosing the right categories ensures your book appears where readers expect it. Start with precise BISAC codes for your genre or subject. Then request additional Amazon browse nodes that match your audience. Focus on nodes that reflect the reader’s search behavior, not what seems popular.

Seven strategic keywords should be mapped for discoverability. Use reader language, not internal jargon. Think about what a potential buyer would type when searching for your book. Avoid keyword stuffing. Each keyword must match the book’s promise in the title, subtitle, or description.

Relevance Rules

• Do not include competitor brand names.
  
• Ensure subtitle and keyword promises align.
  
• Seasonal or topical terms are fine if accurate and helpful.
  
• Keep language natural and easy to read.
  

This approach ensures your book is discoverable while maintaining KDP compliance. Proper mapping improves impressions, ranking stability, and avoids takedowns.

Quote

Metadata Lead: “Categories get you shelved and keywords get you found. Both must tell the same story.”

Category & Keyword Mapper

Field	Entry Example	Notes / Status

[Here’s The Full Case]

Accessibility & Inclusion 

EPUB & A+ Accessibility

Accessibility ensures your book can be enjoyed by all readers, including those using assistive devices. Key steps include:

• Use semantic headings and landmarks in EPUB files to structure content.
  
• Provide descriptive alt text for all images. Avoid text baked into images.
  
• Ensure sufficient contrast for readability.
  
• Include descriptive captions and labeling in A+ content for Kindle and print previews.

Print Readability

Print versions require careful attention to line length, leading, font weight, and contrast. Avoid tiny gray text that is hard to read. Use licensed, accessible fonts that maintain clarity across paper types. Contrast-safe palettes improve legibility for readers with vision impairments.

Quote

Accessibility Lead: “Accessibility is just readability with receipts.”

Accessibility Checklist

Section	Requirement	Status / Notes
EPUB Landmarks	Heading structure, semantic navigation	Verified
Alt-Text	Descriptive for all images and diagrams	Approved
Contrast	Minimum WCAG 2.1 ratio	Checked
Font Licensing	All fonts embedded and licensed	Confirmed
Print Leading & Line Length	Maintain legibility, avoid dense paragraphs	Tested in proof copy
A+ Alt-Text	All graphic elements described	Added
Approval Sign-off	Signature of Accessibility Lead	Completed

Children’s & Illustrated: Specs that Save Cost and Quality 

Fixed-Layout and Read-Aloud Decisions

Choose fixed-layout for picture books or heavily illustrated titles. Decide whether spreads or single-page layouts work best for reading flow. Consider safe areas for illustrations and text to prevent cropping. Plan read-aloud timing if narration or audio features are included. Ensure image DPI and color profiles are correct to avoid quality loss on Kindle and print.

Print Choices for Durability

Select trims that fit standard cartons to reduce shipping and storage costs. Use coated stocks for vibrant illustrations and consider case laminate versus jacket for longevity. For school or library buyers, prioritize durability to prevent page tearing or bending. Optimize binding choices for book thickness and repeated use.

Educator-Friendly Back Matter

Include activity pages, glossaries, and reading level badges if targeting schools or libraries. Ensure back matter is clear and accessible to teachers, librarians, and parents. Properly formatted tables, captions, and references improve usability and reduce support queries.

Quote: Children’s Art Director: “Design for eyes and hands. Contrast, pacing, and durable stock make a real difference in readability and lifespan.”

Children’s/Illustrated Spec Sheet

Section	Key Points	Notes	Owner/Sign-off
