How to Format eBooks for KDP the Right Way

Publishing an eBook on Amazon KDP is one of the best ways to share your story with readers around the world.
But before you click “Publish,” there’s one crucial step that can make or break your book’s success — proper formatting.

Formatting your eBook correctly ensures it looks professional, displays beautifully on all devices, and passes Amazon’s quality checks.
Whether you’re creating a children’s book, a novel, or a non-fiction guide, this article will walk you through how to format eBooks for KDP the right way, step by step.

✏️ 1. Understand How KDP eBooks Work

Before you start formatting, it’s important to understand what Amazon KDP accepts and how eBooks are displayed.

Amazon converts your file into a Kindle-friendly format (usually .mobi or .azw3), which can be read on Kindle devices, tablets, and apps.

There are two main types of Kindle eBooks:

• Reflowable eBooks: Text adjusts automatically to fit different screen sizes (best for novels and text-heavy books).

• Fixed Layout eBooks: Page layout stays the same, preserving the artwork’s position (ideal for illustrated children’s books or design-heavy titles).

Choosing the right format at the start will save you hours of editing later.

💻 2. Choose the Right File Format

KDP accepts several file types, including:

• .docx (Microsoft Word)

• .epub (industry standard for eBooks)

• .kpf (Kindle Create file)

• .html or .htm

• .zip (for eBooks with multiple HTML files or images)

If you’re new to publishing, the easiest and most reliable method is to use Kindle Create, Amazon’s free formatting tool, which automatically converts your document into a Kindle-ready .kpf file.

📄 3. Format Your Manuscript for Digital Reading

When formatting your eBook, remember: what looks perfect on a computer might not look right on a Kindle screen.
Here’s how to format your text properly before uploading.

Set Up the Document

• Use 8.5” x 11” page size for working convenience (KDP adjusts automatically).

• Keep all text left-aligned — centered text can appear uneven on small screens.

• Use standard fonts like Times New Roman, Arial, or Georgia (avoid decorative fonts).

• Font size between 11–13 pt is ideal for readability.

• Remove extra spaces or manual tabs — eBooks flow differently than printed pages.

Structure Your Content

• Add chapter titles using Word’s Heading 1 style.

• Add subheadings with Heading 2.

• Use a consistent spacing (1.15–1.5 line spacing works best).

• Insert page breaks after each chapter — don’t just press Enter multiple times.

Create a Clickable Table of Contents

A linked Table of Contents (TOC) lets readers jump to chapters easily — and it’s required by KDP.
In Word, go to:
References → Table of Contents → Automatic Table.
Kindle Create will automatically detect and format this when you import the document.

🖼️ 4. Add and Optimize Images

Images can make your eBook more appealing, especially for children’s books or illustrated stories.

Follow these guidelines:

• Use JPEG or PNG format.

• Keep resolution at 300 DPI for best quality.

• Compress file size (each image under 5MB ideally).

• Center images and add spacing around them for a clean look.

• Use “Insert → Picture” (not copy-paste) to ensure proper embedding.

For illustrated children’s eBooks, use a fixed layout format to preserve page composition and ensure the artwork stays in place.

📚 5. Review Formatting in Kindle Create

Once your manuscript is ready, open Kindle Create (free from Amazon).

1. Import your .docx file.

2. Choose whether it’s Reflowable or Fixed Layout.

3. Review each page carefully — fix spacing, headings, or image alignment if needed.

4. Add your book title, author name, and front/back matter (like dedication, copyright, or about the author).

5. Insert a clickable Table of Contents if not already detected.

Kindle Create allows you to preview how your book looks on Kindle, tablet, and phone screens.

When finished, export your eBook as a .kpf file — ready for upload to KDP.

🧾 6. Format Your Front and Back Matter

Every professional eBook includes these essential sections:

Front Matter:

• Title page

• Copyright page

• Dedication or quote (optional)

• Table of Contents

Back Matter:

• About the Author

• Other Books by You (if applicable)

• Call to Action (encourage readers to review or follow you)

These pages add professionalism and improve your author brand.

📖 7. Preview Your eBook Before Uploading

Before you upload your eBook to KDP, always preview it thoroughly.
You can use:

• Kindle Previewer (desktop app)

• KDP’s built-in online previewer

Check that:

• Text aligns properly on all screen sizes.

• Images load clearly and fit within margins.

• Hyperlinks (like TOC or website links) work correctly.

• No extra blank pages or odd spacing appears.

This is your final chance to catch formatting errors before publishing.

💲 8. Upload and Publish on Amazon KDP

Go to your KDP dashboard, click “Create a New Kindle eBook,” and fill in your book details:

• Book title and subtitle

• Description (write a keyword-rich summary)

• Keywords and categories

• Upload your .kpf or .epub file

• Upload your eBook cover (JPEG, 2560 x 1600 pixels recommended)

Once uploaded, preview again in KDP’s online previewer. If everything looks perfect, proceed to Pricing and Rights and set your price and royalties.

After submission, Amazon reviews your file — most books are approved and published within 24 to 72 hours.

⚙️ 9. Optimize for the Best Reader Experience

To stand out on Kindle, make sure your eBook:

• Loads quickly (compress large files).

• Has consistent, readable font sizes.

• Uses short paragraphs for mobile readability.

• Includes clickable links to your author website or social media.

Remember: an eBook that looks professional builds trust with readers — and leads to better reviews and sales.

🌟 10. Keep Improving After Publishing

Even after your book is live, you can always upload improved versions.
If readers mention spacing or formatting issues, simply edit your original file, re-export it in Kindle Create, and re-upload it on KDP.

Amazon will automatically update the new version for future buyers. Continuous improvement is the hallmark of a professional author.
