Amazon KDP Formatting Guide 2026: How to Format Your Book for Print & Kindle

By Olayinka Joseph

If you have finished writing your book and are wondering how to format it for Amazon KDP, the most important thing to understand is this: a manuscript that looks good in Microsoft Word is not automatically a print-ready book or a properly formatted Kindle eBook.

For a paperback, you are preparing an actual physical page. That means your trim size, margins, gutter, chapter placement, page numbers, images and bleed have to work together. For Kindle, the approach is different because the text is reflowable and readers can change font sizes and screen settings. Amazon’s current KDP documentation treats print and eBook formatting as separate processes for this reason.

I learned this distinction through actually publishing books, not by reading about it first.

At the beginning when I started self-publishing, I was trying to understand almost every part of the process myself—writing, preparing manuscripts, covers, publishing and eventually building the technical side of my own publishing platform. Over the years, formatting stopped being something I simply “needed to do before uploading a book.” It became part of the publishing process I understood from repeatedly taking manuscripts from a finished Word document to a file ready for publication.

That experience changed the way I format books.

I no longer begin with the question, “What settings should I use in Word?”

I begin with:

What format am I producing, what will the reader see, and what could go wrong when this file leaves my computer?

That is the approach I want to show you in this guide.

What Is KDP Book Formatting?

KDP book formatting is the process of preparing your manuscript so that it displays correctly as a physical print book or as a Kindle eBook.

For a print book, formatting controls things such as:

  • Trim size
  • Page dimensions
  • Margins
  • Gutter
  • Chapter layout
  • Paragraph formatting
  • Page numbers
  • Headers and footers
  • Front matter
  • Back matter
  • Images
  • Bleed
  • Table of contents
  • Final PDF preparation

For a Kindle eBook, the priorities change.

You are dealing with:

  • Reflowable text
  • Heading structure
  • Digital table of contents
  • Paragraph styles
  • Images
  • Hyperlinks
  • Page breaks
  • Front and back matter
  • Device compatibility

This is why I don’t recommend taking the PDF you created for your paperback and simply uploading it as your Kindle manuscript.

Print and Kindle are two different reading experiences.

Amazon’s own eBook formatting guide specifically notes that an eBook needs to be formatted differently from a paperback because Kindle content can change according to the reader’s device and font settings.

The Biggest Formatting Mistake I See First-Time Authors Make

The mistake is starting to format the manuscript before deciding what the finished book is supposed to be.

An author opens Word, selects a font, starts centering chapter titles, adds page numbers and begins adjusting spaces between paragraphs.

Then, 150 pages later, they change the trim size.

Everything moves.

The table of contents changes.

Chapter openings move.

Page numbers change.

Some blank pages appear.

The book suddenly has a different page count.

The cover spine may need to be changed.

I learned to avoid that problem by working from the outside inward.

Before I start detailed formatting, I decide:

  1. Is this a Kindle eBook, print book, or both?
  2. What print size will the paperback use?
  3. Will the print interior have bleed?
  4. What type of book is it?
  5. How much front matter does it actually need?
  6. What structure will the chapters follow?

Only then do I start the detailed layout.

That small change in workflow saves a lot of unnecessary work.

Paperback and Kindle Formatting Are Not the Same

This is worth emphasizing because it causes so many problems.

Paperback

A paperback has fixed physical pages.

If you choose a 6 × 9 inch trim size, the finished page is physically 6 × 9 inches.

The reader cannot pinch the page and make the physical margins larger.

Your inside margin must account for the binding.

Your page numbers have physical positions.

Your chapter openings have physical positions.

Your images have physical positions.

Everything has to fit the printed page.

Amazon identifies 6 × 9 inches as the most common U.S. paperback trim size, although other trim sizes are available and the appropriate choice depends on the type of book you are producing.

Kindle

Kindle is different.

The reader can change:

  • Font size
  • Font appearance
  • Screen orientation
  • Device

The text therefore moves.

A page that appears as page 20 during one preview may not remain page 20 on another device.

That means you should not try to make a Kindle eBook behave like a printed book.

A paperback needs page design. A Kindle eBook needs good structure and reflow.

How I Prepare a Paperback Manuscript for KDP

For the purpose of this guide, I will use Microsoft Word because it remains a practical option for many authors preparing text-heavy books.

Amazon also provides downloadable Word templates for different paperback trim sizes.

1. Choose the Trim Size Before Doing Detailed Formatting

Trim size is the final physical size of your printed book.

For example:

6 × 9 inches

means the finished book will be six inches wide and nine inches high.

This decision affects almost everything that follows.

A different trim size can change:

  • Number of pages
  • Appearance of paragraphs
  • Chapter length
  • Image placement
  • Margins
  • Cover dimensions
  • Spine width

I learned not to treat trim size as a minor setting.

It is one of the first production decisions.

If you are publishing a Christian devotional, business book, teaching book or other text-heavy nonfiction title, look at several professionally published books in the same general category.

Don’t copy one book blindly.

Look at the physical size, typography, margins and overall reading experience.

Then make a deliberate choice.

2. Set the Page Size in Word

Once you know your trim size, set it before doing the rest of the layout.

In Microsoft Word:

Layout → Size → More Paper Sizes

Enter the required width and height.

For a 6 × 9 inch book:

Width: 6 inches
Height: 9 inches

Apply the setting to the entire document.

Do this before spending hours manually positioning chapters.

Amazon’s paperback formatting instructions likewise begin with setting the trim size and then configuring the margins for the selected book.

3. Set Your Margins With the Binding in Mind

This is where a manuscript can look perfectly fine on your computer and still be uncomfortable as a physical book.

The margin nearest the binding is especially important.

That area is often called the inside margin or gutter area.

If the inside margin is too small, the reader has to push the book open just to read the words near the binding.

That is not a formatting problem you want to discover after publication.

KDP’s current requirements specify minimum inside margins according to page count. The required margin increases as the book becomes longer.

So don’t simply say:

“I always use 0.5 inches.”

That is not a complete formatting method.

The correct margin depends partly on the physical specifications of the book.

My practical advice

Set the trim size first.

Determine your approximate page count.

Then check the current KDP margin requirements for that page range.

After that, look at the actual page visually.

Technical compliance is the minimum.

You still want the finished page to feel comfortable to read.

4. Decide Whether Your Interior Needs Bleed

Bleed is another area where beginners can become confused.

Suppose your page contains only text.

You probably don’t need the artwork to run all the way to the edge.

But imagine you have a full-page photograph or a background design that touches the edge of the page.

That is different.

The image needs to extend beyond the final trim area so that the printed page can be trimmed without leaving an unwanted white strip.

Amazon’s current guidance requires print manuscripts containing interior bleed to be uploaded as PDF files.

A simple way to think about it

Text-only page: usually no bleed.

Full-page image/background reaching the edge: bleed may be required.

Don’t add bleed simply because you saw another author doing it.

Use it when the design actually requires it.

5. Stop Formatting Paragraphs Manually

This is one of the habits that caused me unnecessary work when I was learning publishing.

If you manually format every paragraph, every chapter heading and every section, you eventually create a document that is difficult to control.

One chapter changes.

Another chapter doesn’t.

One heading has 18-point spacing.

Another has 24.

One paragraph has an indentation.

Another has several spaces.

Eventually the manuscript becomes a collection of little formatting decisions.

Styles solve much of this problem.

In Word, I recommend setting up styles for recurring elements such as:

  • Normal — body text
  • Heading 1 — chapter titles
  • Heading 2 — major sections
  • Heading 3 — smaller subsections where necessary

Once the styles are established, you can change the appearance of all corresponding sections without hunting through the manuscript one page at a time.

Amazon’s own Word formatting instructions recommend using styles for body text and chapter headings.

6. Format the Body Text for Reading, Not Decoration

A book is not a poster.

The purpose of body typography is to make long-form reading comfortable.

Pay attention to:

  • Font choice
  • Font size
  • Line spacing
  • Paragraph indentation
  • Paragraph spacing
  • Alignment
  • Consistency

Amazon’s current paperback guidance gives examples of body-text settings and notes that font size should be chosen according to the font and the book’s reading needs.

You don’t need an unusual font to make your book look professional.

In fact, trying too hard to make the body text visually impressive can make the book harder to read.

I prefer to make the formatting quiet.

The reader should notice the content—not fight with the typography.

7. Format Chapter Openings Consistently

A chapter should look like it belongs to the same book as every other chapter.

For example, if Chapter 1 begins with a large centered heading, Chapter 2 should not suddenly use a small left-aligned heading.

Create one chapter-title style and use it throughout the manuscript.

A simple structure might be:

CHAPTER 1

YOU WERE SAVED TO LIVE A VICTORIOUS LIFE

Then the chapter text.

The exact design is up to you.

The important part is consistency.

One of the advantages of using Heading 1 properly is that those headings can later be used to build your table of contents. Amazon specifically recommends applying heading styles to chapter titles for this reason.

8. Give Every Chapter a Proper Break

Don’t create a new chapter by pressing Enter repeatedly until the next page appears.

Use a page break.

In Word:

Insert → Page Break

This tells Word that the next chapter starts on a new page.

It is much cleaner than creating artificial empty space with multiple paragraph returns.

It also makes the document easier to maintain when the page count changes.

This is one of those small technical habits that makes a major difference when you are formatting a book repeatedly.

9. Build Your Front Matter Before Chapter 1

Front matter is the material that appears before the main body of your book.

Depending on the book, this can include:

  • Half-title page
  • Title page
  • Copyright page
  • Dedication
  • Table of contents
  • Foreword
  • Preface
  • Introduction

Not every book needs all of them.

For many of the books I work with, keeping the front matter simple is better.

For example:

Title Page

↓

Copyright Page

↓

Dedication

↓

Table of Contents

↓

Introduction

↓

Chapter 1

There is no prize for adding six preliminary pages to a book that only needs three.

Amazon’s current templates also allow authors to customize or remove front-matter elements according to the needs of the book.

10. Create the Table of Contents From Your Heading Styles

Don’t type your table of contents manually unless there is a specific reason to do so.

If you have properly applied Heading 1 to your chapter titles, Word can build the table of contents from those headings.

In Word:

References → Table of Contents

Select an automatic table.

This is particularly useful while the manuscript is still changing.

Suppose Chapter 4 moves from page 37 to page 42.

An automatic table of contents can be updated.

A manually typed one cannot know that Chapter 4 has moved unless you change it yourself.

For a print book, page numbers matter.

For Kindle, the navigation structure matters.

So the underlying heading structure is important for both formats, even though the final result is different.

11. Be Careful With Page Numbers

Print books have physical pages.

Kindle books don’t work that way.

For a paperback, you may want page numbers in the main body while leaving certain front-matter pages without visible numbers.

You can achieve this using section breaks in Word.

Don’t put page numbers everywhere simply because Word makes it easy.

Think about the actual reading experience.

For example, you may want:

  • No visible page number on the title page
  • No visible number on certain opening pages
  • Page numbering beginning with the main text
  • Consistent positioning throughout the main body

The exact approach depends on the book.

Amazon’s print formatting instructions include pagination and section-break guidance for this reason.

12. Don’t Ignore Headers and Footers

Headers and footers can make a printed book feel finished, but they are not compulsory for every book.

For a simple devotional or short nonfiction book, you may decide that a clean page without a running header works better.

For a longer book, you may use:

  • Book title
  • Author name
  • Chapter title

But don’t add headers simply to make the book look more complicated.

And remember: Kindle eBooks are different.

Amazon’s eBook guidance specifically notes that page numbers, headers and footers generally don’t belong in reflowable Kindle manuscripts because readers can change the font size and screen layout.

13. Handle Images Carefully

Images introduce another layer of formatting.

Before putting an image into your book, check:

  • Do you have permission to use it?
  • Is it high enough quality?
  • Is it positioned correctly?
  • Does it need to bleed?
  • Is text being pushed awkwardly around it?
  • Does it still look correct in the final PDF?

For KDP print books, Amazon’s current template guidance says images should be high resolution, with 300 DPI identified as the high-resolution standard in its pre-publication checklist.

Don’t judge an image only from the screen.

A picture that looks acceptable in Word can expose quality problems when printed.

14. Check Your Blank Pages

This is one of the things I specifically look for before considering a print manuscript finished.

A blank page is not automatically an error.

Sometimes a blank page is intentional.

For example, a chapter may need to begin on a right-hand page in a particular book design.

The problem is an unintended blank page.

Those usually come from:

  • Extra paragraph returns
  • Incorrect page breaks
  • Section breaks
  • Odd/even page settings
  • Changes in formatting

When you preview the book, don’t simply look at the text.

Flip through the pages as though you are the reader.

If you see a blank page, ask:

Was I trying to create this page?

If the answer is no, find out why it is there.

15. Export the Paperback Interior as a PDF

When the paperback manuscript is finished, the print file should be treated as a production file, not simply another Word document.

Amazon recommends PDF for print manuscripts, and PDF is required for interiors containing bleed.

Before exporting:

  • Turn off Track Changes.
  • Accept or reject outstanding revisions.
  • Check spelling manually.
  • Check the table of contents.
  • Check page numbers.
  • Check images.
  • Check chapter openings.
  • Check blank pages.
  • Check margins.
  • Check the final page count.

Amazon also specifically warns authors to turn off Track Changes and manually proofread the manuscript rather than relying entirely on automated spelling and grammar tools.

I would add one more thing:

Open the exported PDF and inspect it.

Don’t assume that because Word looked correct, the exported PDF must also be correct.

How I Check a Paperback Before Uploading It

This is my basic final pass.

I don’t read the manuscript only as an author.

I read it as someone holding the finished book.

I check:

Page 1

Does the book begin where it should?

Chapter openings

Are they consistent?

Body pages

Are the paragraphs comfortable to read?

Inside margin

Does the text sit comfortably away from the binding?

Page numbers

Are they present where they should be and absent where they shouldn’t?

Images

Are they sharp and correctly positioned?

Table of contents

Do the chapter names and page numbers correspond?

Last pages

Does the book end cleanly?

Overall page flow

Does anything look strangely empty, crowded or out of place?

This visual inspection catches things that a technical checklist can miss.

How to Format a Kindle eBook for KDP

Now we need to separate the Kindle version from the paperback.

This is where many authors make their second major formatting mistake.

They take the finished paperback PDF and assume:

“This is already my book, so I’ll upload the same thing to Kindle.”

I don’t recommend that approach.

The Kindle edition should be prepared as an eBook.

Amazon’s current eBook guide explains that Kindle manuscripts are reflowable and specifically advises authors to format the eBook separately from the paperback.

1. Start With a Clean Manuscript

For a text-heavy Kindle book, I prefer starting from a clean Word document rather than trying to force the finished print layout into the eBook.

Remove unnecessary print-specific formatting.

The Kindle version should not depend on:

  • Fixed page numbers
  • Print headers
  • Print footers
  • Physical gutters
  • Fixed page dimensions

The content needs to be able to move.

2. Use Proper Paragraph Indentation

Do not create paragraph indentation by pressing the Tab key.

Amazon specifically warns that tab spacing does not convert reliably to Kindle. Instead, paragraph indentation should be established through formatting settings/styles.

This is a small detail, but it matters.

When formatting an eBook, avoid using spaces and tabs as substitutes for actual formatting.

Tell the document what the paragraph should look like.

Don’t try to force the appearance manually.

3. Use Heading 1 for Chapter Titles

The same principle applies here.

Use Heading 1 for your chapter titles.

For example:

Chapter 1

The Beginning of Your Journey

Then use the appropriate heading levels for subsections if your book requires them.

This creates structure that Kindle can understand.

It also makes the table of contents easier to create.

4. Create a Proper Kindle Table of Contents

A Kindle table of contents is not simply the same thing as a printed table of contents.

The reader should be able to navigate between sections.

That means the chapter structure needs to be correctly defined.

Amazon’s current eBook formatting guidance specifically includes creating a table of contents as part of preparing a Kindle manuscript.

Before publishing, test the navigation.

Click the chapter links.

Make sure they actually take the reader to the intended location.

A table of contents that looks beautiful but has broken navigation is not finished.

5. Use Page Breaks Between Chapters

Just as with print formatting, don’t create a new chapter by pressing Enter repeatedly.

Use a page break.

This tells the Kindle document where one chapter ends and the next begins without filling the document with unnecessary blank paragraphs.

6. Don’t Add Print Page Numbers to Kindle

This is another difference between the formats.

A Kindle reader’s page display can change depending on the device and font settings.

Amazon therefore advises that eBooks don’t need traditional page numbers, headers or footers.

So don’t try to reproduce the printed page numbering system inside the Kindle manuscript.

Let Kindle handle the reading environment.

7. Keep Images Appropriate for Kindle

If your book contains images, check how they appear on smaller screens.

An image that looks excellent on a desktop monitor can become awkward on a phone.

Ask:

  • Is the image still readable?
  • Is the text inside the image large enough?
  • Does the image sit correctly?
  • Does it push the surrounding text into an awkward position?
  • Does it work in portrait orientation?

The Kindle version should be tested as a digital reading experience, not merely checked as a document.

8. Add Hyperlinks Where They Actually Help

Kindle gives you something a paperback cannot easily provide:

clickable links.

Use them where they improve navigation.

For example:

  • Website
  • Author page
  • Related book
  • Resource page
  • Reference
  • Contact page

Don’t turn every other sentence into a hyperlink.

Links should help the reader, not make the book look like a website.

9. Keep Kindle Front and Back Matter Simple

A Kindle book can contain:

  • Title page
  • Copyright
  • Dedication
  • Table of contents
  • Introduction
  • Main chapters
  • About the author
  • Other books
  • Author website

The same content can exist in the paperback, but the formatting doesn’t have to be identical.

Think about what the reader needs on a digital device.

Kindle Create: Should You Use It?

Amazon provides Kindle Create as one option for preparing eBooks, and it can be useful for authors who don’t want to manually manage every aspect of Kindle formatting. Amazon also describes Kindle Create as an option for text-heavy books with relatively simple layouts.

I don’t believe every author needs to use one specific formatting tool.

The important thing is understanding what the tool is producing.

A button that says “export” does not remove the responsibility to inspect the result.

You still need to preview the book.

The KDP Previewer Is Not Optional in My Workflow

If there is one part of this process I would strongly encourage a new author not to skip, it is the preview stage.

KDP provides preview tools so you can inspect your manuscript before publication.

When I preview a book, I’m not looking only for spelling mistakes.

I’m looking for production mistakes.

For a paperback, I check:

  • Chapter openings
  • Page breaks
  • Margins
  • Gutter
  • Page numbers
  • Headers
  • Footers
  • Images
  • Table of contents
  • Blank pages
  • Final page
  • Overall page balance

For Kindle, I check:

  • Chapter navigation
  • Table of contents
  • Heading structure
  • Paragraph spacing
  • Images
  • Links
  • Page breaks
  • Front matter
  • Back matter

If I find something wrong, I don’t try to live with it.

I go back to the source file.

Fix it.

Export again.

Upload again.

Preview again.

That cycle is normal.

Why I Recommend Ordering a Proof Copy for Print Books

A PDF can tell you a lot.

It cannot completely replace holding the physical book.

A proof copy lets you check things such as:

  • Actual text size
  • Physical margins
  • Binding area
  • Image quality
  • Paper appearance
  • Cover alignment
  • Spine appearance
  • Overall page feel

Amazon’s current paperback template guidance also recommends ordering a proof copy so authors can review the physical book before making it available to customers.

If the book matters enough to publish, it matters enough to inspect.

My Practical KDP Formatting Workflow

After years of working through the publishing process, this is the order I would recommend rather than jumping randomly between settings.

Step 1 — Finish the manuscript

Don’t start detailed formatting while the manuscript is still changing heavily.

Step 2 — Decide the formats

Determine whether you are producing:

  • Kindle
  • Paperback
  • Hardcover
  • Multiple editions

Step 3 — Choose the print trim size

Do this before detailed print formatting.

Step 4 — Set up the Word document

Configure:

  • Page size
  • Margins
  • Styles
  • Paragraphs
  • Chapter headings

Step 5 — Format the front matter

Add only what the book needs.

Step 6 — Format the chapters

Apply consistent heading and body styles.

Step 7 — Add the back matter

Keep it useful.

Step 8 — Build the print table of contents

Update it after the manuscript is stable.

Step 9 — Check pagination

Look through the entire book.

Step 10 — Handle images and bleed

Make sure they follow the requirements for the chosen format.

Step 11 — Export the paperback PDF

Then inspect the PDF itself.

Step 12 — Prepare the Kindle version separately

Don’t simply assume the paperback file is your Kindle file.

Step 13 — Preview both versions

Check them as readers.

Step 14 — Correct the problems

Then preview again.

Step 15 — Order a print proof

For a physical edition, inspect the actual book before considering the production process finished.

That is a much safer workflow than uploading a Word document and hoping Amazon will make it look like a book.

10 KDP Formatting Problems Worth Checking Before You Publish

Here is the checklist I would actually use.

1. Wrong trim size

Your document dimensions don’t match the print edition you selected.

2. Inside margin is too small

Text sits too close to the binding.

3. Inconsistent chapter headings

Different chapters have different typography.

4. Manual paragraph formatting

The manuscript is full of spaces, tabs and repeated Enter presses.

5. Broken table of contents

The displayed page numbers or Kindle navigation don’t correspond to the actual chapters.

6. Unwanted blank pages

Extra breaks or section settings have created pages you didn’t intend.

7. Images are too low quality

They look fine on screen but poor in print.

8. Bleed is incorrectly configured

Images or backgrounds that reach the page edge haven’t been prepared correctly.

9. Paperback and Kindle versions are treated as identical

The print layout is being forced into a reflowable digital format.

10. The author never checks the final result

The manuscript is uploaded and published without a serious preview.

That last one is the easiest to prevent.

You Don’t Need Complicated Software to Format a Good KDP Book

One thing I learned from self-publishing is that technology can either help you or distract you.

You do not necessarily need an expensive design program to prepare a text-heavy book.

A properly structured Microsoft Word document can be enough for many straightforward books, particularly when you understand:

  • Styles
  • Page dimensions
  • Margins
  • Section breaks
  • Page breaks
  • Tables of contents
  • Images
  • PDF export

KDP itself provides Word templates and formatting instructions for authors who want to work this way.

The software is only part of the equation.

Knowing what the finished book should look like is more important.

Don’t Confuse Formatting With Editing

There is another lesson worth mentioning.

Formatting cannot rescue a poorly edited manuscript.

You can produce beautiful margins, elegant chapter headings and a perfect PDF—and still have a book containing:

  • Repeated paragraphs
  • Spelling errors
  • Missing words
  • Broken sentences
  • Incorrect Bible references
  • Inconsistent terminology
  • Poor chapter structure

Formatting should come after the manuscript has reached a reasonably stable editorial stage.

Otherwise, every major editorial change can disturb your layout.

This is particularly important when you are publishing books repeatedly.

The more books you produce, the more valuable a consistent production workflow becomes.

If you are still at the manuscript stage, my guide on how to write your first book step by step can help you separate the writing stage from the production stage.
