How to Upload a Book to KDP
Complete Step by Step Guide 2026

Your manuscript is written. Your cover is ready. Now what? This guide walks you through every screen, every field, and every setting in the KDP upload process — so your book goes live without rejections, delays, or surprises.

How to upload a book to KDP — laptop showing KDP upload dashboard with completed upload
The KDP upload process takes 20–40 minutes if your files are prepared correctly — and this guide makes sure they are.

Most first-time KDP authors assume the upload process is the hard part. It is not. The hard part is preparing your files correctly so the upload does not fail. If your manuscript PDF has the right dimensions, embedded fonts, and correct margins — and your cover file has the right spine width for your page count — the actual upload takes less than 30 minutes and your book is live within 72 hours.

This guide covers the entire process in the exact order you encounter it inside KDP, including every field you will see, what it means, what to put in it, and what happens if you get it wrong.

Before You Start — Have These Files Ready

Nothing slows down a KDP upload more than stopping halfway to fix a file that is not ready. Before you log into KDP and click “Create a New Title,” make sure you have everything prepared. You can save your progress in KDP at any stage, but it is cleaner to go through the whole process in one sitting.

KDP upload preparation — manuscript, cover file and checklist on dark desk
Have your manuscript PDF, cover file, and book details ready before starting the upload — it avoids stopping halfway.

For a Paperback Upload

  • Manuscript PDF — Sized exactly to your trim size (e.g. 6″×9″), with all fonts embedded, correct gutter margins, and no security or password protection
  • Cover PDF — Full wrap (front + spine + back) as a single PDF. Spine width must match your page count and paper type exactly
  • Book title and subtitle — Exactly as it will appear on Amazon. Decide this before you start.
  • Book description — Your sales copy, up to 4,000 characters. Write this in a text editor first.
  • 7 keyword phrases — Researched and written out. Each field accepts up to 50 characters.
  • 2 categories selected — Know your BISAC categories before you start. Have a backup in case your first choice is not available.
  • ⚠️
    Tax information completed — In your KDP account settings. If not done, KDP withholds 30% of royalties by default.

For a Kindle eBook Upload

  • EPUB file — Amazon recommends EPUB since deprecating MOBI in 2022. Alternatively: DOCX from Word, or HTML.
  • Kindle eBook cover — JPEG, minimum 625×1000px, ideal 1600×2560px, RGB colour, under 50MB
  • Same metadata — title, description, keywords, and categories as above

Get Your Files KDP-Ready First

If your manuscript is not yet formatted correctly, use our free KDP Paperback Formatter to auto-apply the right margins, gutter, and bleed to your PDF in seconds. For cover dimensions, use our Spine Width Calculator to get the exact measurements for your trim size and page count.

1
Log In and Create a New Title

Go to kdp.amazon.com and sign in with your Amazon account. You land on your KDP Bookshelf — the main dashboard that shows all your published and draft titles.

To start a new book, click the gold “+ Paperback” button under “Create a New Title.” You will see three format options:

  • Kindle eBook — Digital version. Appears on Kindle devices and the free Kindle reading apps.
  • Paperback — Print-on-demand physical book. Most authors start here.
  • Hardcover — Premium print-on-demand. Higher printing cost, but allows a higher price point.

If you want to publish all three formats, you create each one separately — but they will be linked automatically on the same Amazon product page if you upload them with the same title, author name, and matching ISBN details. Start with the format you are most ready for and add the others later.

ℹ️

You Can Save and Come Back

KDP saves your progress as a draft automatically. You do not need to complete all three sections in one sitting. That said, the process flows better when you have everything ready and go through it start to finish in one session.

2
Fill In Your Book Details
KDP Book Details form — title, subtitle, author name, and description fields
Section 1 of the KDP upload: Book Details. This is where your Amazon listing is built — get your title, subtitle, and description right the first time.

Section 1 of the KDP upload is called “Book Details.” This is where you build your Amazon listing. Every field here affects how your book appears to buyers searching on Amazon — so it deserves more thought than most authors give it.

Book Title

Enter your title exactly as it will appear on the cover and on Amazon. KDP is strict about this — the title on the copyright page, the cover, and the KDP dashboard must all match. Do not add keywords to the title field that do not appear on your actual cover. Amazon can suppress or reject books where the metadata title does not match the cover title.

Subtitle (optional but important)

The subtitle field is where you can naturally include your main keyword phrase. A subtitle like “A Step-by-Step Guide for First-Time Self-Publishers” includes discoverable keywords and adds context for buyers. Keep it honest and descriptive — it should actually describe the book. Amazon monitors subtitles for keyword stuffing and will flag or suppress titles that abuse this field.

Series

If your book is part of a series, enter the series name and volume number here. This creates a series page on Amazon that links all volumes together. If your book is standalone, leave this blank.

Edition Number

Leave this blank for most books. Only use it if you are publishing a revised second or third edition of a previously published title.

Author

Enter your author name exactly as you want it displayed on Amazon. This becomes your author identity on the platform — it appears on your book page, in search results, and on your Author Central page. If you are using a pen name, enter it here. You can have multiple pen names under one KDP account.

Contributors (optional)

If your book has an editor, illustrator, translator, or co-author, you can add them here with their role. This is optional and does not affect discoverability. It does appear on your Amazon book page.

Description

This is your book’s sales copy on Amazon — the text buyers read before deciding to purchase. KDP allows up to 4,000 characters and supports a limited set of HTML tags: <b> for bold, <i> for italic, <br> for line breaks, <h4> through <h6> for headings, and <ul>/<li> for bullet points. Most authors do not format their descriptions at all, which is a mistake — a well-formatted description with a strong opening hook and clear benefit statements outsells a wall of plain text every time.

Publishing Rights

Select “I own the copyright and I hold the necessary publishing rights.” This is the standard selection for original work. Only select “This is a public domain work” if you are publishing a title where the copyright has genuinely expired.

💡

Write Your Description in a Text Editor First

Do not write your book description directly in the KDP dashboard. Write it in a document first, then add your HTML formatting tags, then paste it into KDP. The KDP description field is uncomfortable to work in and does not preview formatting until after you save.

3
Keywords and Categories — Do Not Rush These

Most authors spend 90% of their time on the manuscript and 5 minutes on keywords and categories. This is backwards. Keywords and categories are how Amazon decides when to show your book to potential buyers. Getting them wrong means your book is effectively invisible on the platform no matter how good it is.

The 7 Keyword Fields

KDP gives you 7 keyword fields, each accepting up to 50 characters. A few things to understand about how these work:

  • Amazon already indexes your title, subtitle, and description automatically — do not repeat those words in your keyword fields.
  • Use phrases, not individual words. “cozy mystery small town female detective” is infinitely more useful than “mystery.”
  • Amazon matches your book to search queries that contain any part of your keyword phrase — so a 50-character phrase covers more ground than a 10-character single word.
  • Think about what your reader is actually typing into Amazon search when they want a book like yours. Not what you would type. What they would type.
  • Never use competitor author names, ASIN numbers, or trademarked terms — Amazon explicitly prohibits this and will suppress your book.
  • You can change your keywords at any time after publishing. This is one of the few metadata fields that is reversible.

The 2 Categories

KDP lets you choose 2 categories during upload, but here is the thing most guides do not mention: after publishing, you can contact KDP support and request up to 8 additional categories, for a maximum of 10 total. The authors who do this consistently outperform those who do not, because more categories means more bestseller list placements, which means more visibility.

The strategy for choosing categories is counterintuitive. Your first instinct will be to find the most relevant, most popular category. That is often the wrong choice. A book in “Mystery > General” is competing against 300,000 titles. The same book in “Mystery > Cozy > Amateur Sleuth” might compete against 3,000. Your chances of reaching the top 100 — and getting the bestseller badge — are dramatically higher in a specific sub-category.

Category LevelCompetitionBestseller Badge?Strategy
Top level (Mystery)300,000+ titlesAlmost impossibleAvoid as primary
Mid level (Mystery > Cozy)30,000–80,000Difficult but possibleUse as one of your 10
Specific sub-category500–5,000AchievableTarget this level
⚠️

You Only See 2 Categories at Upload — That’s Not the Limit

After your book goes live, email KDP support at amazon.com/gp/help/contact-us. Tell them your ASIN and the exact category paths you want to add (e.g. “Kindle Store > Kindle eBooks > Mystery > Cozy > Amateur Sleuth”). They typically add them within 24–48 hours, no questions asked.

4
Upload Your Manuscript File
KDP manuscript upload — PDF file being uploaded to KDP dashboard
KDP accepts PDF, DOCX, and HTML for manuscripts. PDF gives you the most control over the final printed output.

Section 2 of the KDP upload is called “Content.” This is where you upload your actual files. You also assign your ISBN, choose your interior settings, and set your trim size here.

ISBN — Free vs Your Own

The first thing KDP asks in Section 2 is whether you want a free KDP-assigned ISBN or if you will provide your own. For most self-publishers, the free KDP ISBN is the right choice. It is registered under “Independently Published” as the publisher name — which does not affect sales in any meaningful way. If you want your own publishing company name on the ISBN, you need to purchase one from Bowker in the US ($85–$295 per ISBN) or Nielsen in the UK.

Publication Date

You can set this to the current date or a past date if your book was previously published elsewhere. This shows on your Amazon listing as the “Date First Available” and is sometimes used by readers to gauge how current a non-fiction book is. For fiction, most readers do not care about this date.

Interior Settings — Choose Carefully

Interior Type: Black & White or Full Color

This is one of the most consequential decisions in the whole upload process because you cannot change it after publishing without creating a new listing. Black and white printing costs $0.012 per page. Color printing costs $0.07 per page — nearly 6 times more. A 250-page color book costs approximately $18.35 to print, which means you would need to price it at $30+ to earn a reasonable royalty. Unless your book genuinely requires color (children’s picture books, art books, certain cookbooks), choose Black and White.

Paper Type: White or Cream

White paper has higher contrast and is better for books with images, charts, or technical content. Cream paper is warmer and easier on the eyes for long fiction reads — it is the industry standard for novels and literary non-fiction. Both cost the same to print. Cream paper is approximately 10% thicker per page, which means your spine will be slightly wider. If your cover is already designed, check whether your spine width was calculated for white or cream before switching.

Trim Size

This must match your manuscript PDF dimensions exactly. If you select 6″×9″ here but your PDF is sized to 8.5″×11″, KDP will reject the file or scale it incorrectly. There is no way to fix this except to reformat your manuscript to the correct size. Use our KDP Book Sizes Chart if you are unsure which size matches your manuscript.

Uploading the Manuscript File

Click “Upload Paperback Manuscript.” KDP accepts PDF, DOCX, and HTML. For the best results with a professionally formatted book, use PDF. When you upload a PDF:

  • All fonts must be embedded. If they are not, KDP either rejects the file or substitutes a different font. Check your PDF in Acrobat under File → Properties → Fonts. Every font listed should say “Embedded Subset.”
  • The PDF should not have any security settings, password protection, or digital rights management applied.
  • Images should be 300 DPI or higher for clean print quality.
  • The file size limit is 650MB, but most books are well under 50MB.

What KDP Does With Your Uploaded File

After you upload, KDP runs an automated check on your manuscript. This typically takes 1–3 minutes. If the file has issues — wrong dimensions, non-embedded fonts, resolution problems — KDP will show you a yellow warning or a red error. Yellow warnings mean the file will be accepted but may have minor print quality issues. Red errors mean the file is rejected and must be corrected before you can proceed.

The most common error messages and what they actually mean:

  • “Fonts not embedded” — Open your PDF in Word or InDesign, re-export with PDF/A compliance checked, and re-upload.
  • “File dimensions do not match selected trim size” — Your PDF page size is wrong. Reformat your manuscript to the correct trim dimensions.
  • “Low resolution images” — One or more images in your manuscript are under 300 DPI. Re-embed at 300 DPI and re-upload.
  • “Blank pages detected” — You likely have extra blank pages at the end or between chapters. This is usually fine for printing but worth checking.
5
Upload Your Cover File
KDP full wrap cover template — front cover, spine, and back cover laid out as single file
For paperbacks, KDP requires a full wrap cover — one single PDF containing the front cover, spine, and back cover exactly sized for your page count and paper type.

For a Kindle eBook, your cover upload is simple: a JPEG or TIFF file, ideally 1600×2560 pixels. That is a ratio of 1:1.6, which Amazon calls the standard Kindle cover format. Use our free eBook Cover Resizer to check and resize your cover to KDP’s exact requirements.

For a paperback, the cover upload is more involved and is where a surprising number of first-time authors hit a rejection. Here is why: you need a full wrap cover — a single PDF that contains your back cover, spine, and front cover all in one file, sized to exact pixel dimensions based on your specific trim size, page count, and paper type. If any of these three variables is wrong, the cover will not line up correctly when printed.

Calculating Your Full Wrap Cover Size

The spine width is the critical measurement. It is calculated by multiplying your page count by the thickness per page for your paper type:

  • White paper: 0.002252 inches per page
  • Cream paper: 0.0025 inches per page
  • Color paper: 0.002347 inches per page

A 300-page book on white paper has a spine of 300 × 0.002252 = 0.6756 inches. Add 0.125″ bleed on each edge and the full wrap width is (front cover width + 0.125″) + spine width + (back cover width + 0.125″). For a 6×9 paperback at 300 pages on white paper, that works out to approximately 12.95″ × 9.25″ total document size.

Get Your Exact Cover Dimensions Free

Enter your trim size, page count, and paper type into our Spine Width Calculator. It gives you the exact spine width, front cover dimensions, back cover dimensions, and total wrap size in both inches and pixels.

Cover File Requirements for Paperbacks

  • Single PDF file containing front + spine + back in one document
  • Minimum 300 DPI for all images and graphics in the cover
  • Colour space: RGB or CMYK — KDP converts to CMYK for print. If you design in RGB, the print colours will shift slightly. Designing in CMYK from the start gives you more predictable colour output.
  • Maximum file size: 400MB (most covers are under 20MB)
  • Text and important design elements must be at least 0.125″ away from the trim line — anything too close to the edge risks being cut off after printing

Do I Need a Barcode?

No. Amazon KDP automatically places the ISBN barcode on your back cover after you upload the file. You do not need to include one in your design. Some designers leave a white box on the back cover for the barcode — this is fine but not required. KDP will overlay the barcode regardless of what is on your back cover design.

⚠️

Cover Errors Are the #1 Rejection Reason

The most common cover rejection is a spine that is too wide or too narrow for the actual page count. This happens when authors design the cover before finalising the page count, then the formatted manuscript turns out to have a different number of pages than expected. Always calculate your spine width from the final formatted manuscript, not the Word document page count.

Preview Your Book — Do Not Skip This
KDP book preview — reviewing manuscript interior in the KDP online previewer before publishing
The KDP online previewer shows your book exactly as it will be printed. Check every single page — not just the first few.

After uploading both your manuscript and cover, KDP shows a “Launch Previewer” button. This opens an online reader that shows your book exactly as it will look in print (for paperbacks) or on a Kindle device (for eBooks). Do not skip this step.

The previewer is the last chance to catch problems before your book goes live. Problems that are common in the previewer and easy to miss:

  • 1

    Check the first few pages

    Title page, copyright page, dedication, and table of contents. Make sure your copyright page has the correct year and author name, and that your TOC links work if it is an eBook.

  • 2

    Check every chapter opening

    Chapter titles should be on the correct page — for a traditionally formatted book, chapters start on a right-hand (odd-numbered) page. If your chapter 3 opens on a left-hand page, you need to add a blank page before it in your manuscript.

  • 3

    Check the gutter on several pages

    Flip through a few pages and look at the inner margin — the side closest to the spine. Text should not be too close to the binding. If you see text cutting off near the inner edge, your gutter is insufficient for your page count.

  • 4

    Check any images or diagrams

    Images should be sharp in the previewer. If an image looks slightly blurry, it is likely under 300 DPI and will print soft. Re-embed at higher resolution before uploading.

  • 5

    Check headers and footers

    Page numbers should be consistently placed and not cut off. Headers showing chapter titles or author names should be within the safe margin area on every page.

  • 6

    Check the cover preview

    The previewer also shows a 3D rendering of your cover. Check that the spine text is centered, readable, and not running off the edges. Check that the front and back cover images look correct and are not stretched.

If you find a problem in the previewer, close it, fix your file, re-upload, and preview again. There is no limit to how many times you can re-upload before publishing. It is better to re-upload five times in the dashboard than to discover a problem after your book is live and customers have already received copies.

7
Set Your Price and Royalty Plan
KDP pricing settings — list price and royalty plan selection in KDP dashboard
Section 3 of KDP upload: Pricing. Choose your royalty plan and set your list price for each marketplace separately.

Section 3 is called “Pricing.” This is where you choose your royalty plan and set your list price for each marketplace. KDP distributes to dozens of Amazon marketplaces worldwide, and you can set a price for each one individually or use their automatic currency conversion.

Publishing Territories

Select “All territories (worldwide rights)” unless you have specific rights restrictions. Most self-published authors own their rights in all territories, so this is the standard selection. If you are a traditionally published author publishing a self-published title alongside your traditionally published work, check your traditional publishing contract before selecting this — some contracts include territorial rights clauses.

Royalty Plan

For Kindle eBooks, you choose between 35% and 70% royalty. The 70% plan requires your book to be priced between $2.99 and $9.99 in most marketplaces. Below $2.99 or above $9.99, you earn only 35%. For most authors, pricing between $2.99 and $4.99 on the 70% plan is the highest-earning strategy.

For paperbacks, the royalty is always 60% of the list price minus the printing cost. There is no plan to choose — it is automatic.

FormatRoyaltyPrice RangeDeductions
Kindle eBook (35%)35% of list price$0.99–$200None
Kindle eBook (70%)70% of list price$2.99–$9.99~$0.06/MB delivery fee
Paperback60% of list priceAbove break-evenPrinting cost deducted

Setting Your List Price

For paperbacks, KDP shows you the printing cost and the minimum list price before you enter your price. The minimum is the price at which you earn exactly $0 per copy — everything goes to printing. You want to set your price well above this. Most self-published paperbacks are priced between $9.99 and $19.99, depending on page count and genre.

Use the formula: add your target royalty per copy to your printing cost, then divide by 0.60. If your printing cost is $4.45 and you want to earn $5 per copy: ($4.45 + $5.00) ÷ 0.60 = $15.75. Price at $15.99.

💰 Calculate Your Royalty Before Setting Price

Enter your page count, trim size, and target price to see exactly what you earn per copy and what your break-even price is.

KDP Select Enrollment

At the bottom of the pricing section, KDP asks if you want to enroll your Kindle eBook in KDP Select. This makes your eBook available to Kindle Unlimited subscribers and gives you access to promotional tools like Kindle Countdown Deals and Free Book Promotions. The trade-off: your eBook must be exclusive to Amazon for 90-day periods. If you sell your eBook anywhere else — your own website, Apple Books, Google Play, Kobo — you cannot enroll in KDP Select.

For most genre fiction authors, KDP Select is worth it. Kindle Unlimited readership is particularly high in romance, fantasy, thriller, mystery, and science fiction. For non-fiction authors who have their own direct sales channels or want wide distribution, staying out of KDP Select is often the better long-term choice.

Submit for Publishing

Once you have completed all three sections — Book Details, Content, and Pricing — and reviewed your book in the previewer, you will see a “Publish Your Kindle Book” or “Submit for Publishing” button at the bottom of Section 3.

Before clicking it, do one final check:

  • Manuscript previewed — every page checked
  • Cover previewed — spine text readable, no cropping
  • Title matches cover exactly
  • Author name spelled correctly
  • Description formatted with HTML — reads well on Amazon listing
  • 7 keyword fields filled with phrase-based keywords
  • 2 specific sub-categories selected
  • Price above break-even, on 70% plan if Kindle eBook
  • ⚠️
    Tax information and payment details confirmed in account settings

When you click Submit, KDP begins its review. You will see your book status change to “In Review” on your bookshelf. Do not click Submit again — multiple submissions do not speed up the process and can cause errors.

After Publishing — What Happens and What to Do

Amazon book listing live on mobile — author viewing their newly published KDP book on Amazon
Within 72 hours of submitting, your book is live on Amazon and visible to millions of buyers worldwide.

Timeline After Submission

  • Kindle eBooks: Usually live within 24–48 hours of submission. Amazon’s review is typically fast for eBooks.
  • Paperbacks: Usually live within 24–72 hours, but can take up to 5 business days if the cover file triggers a manual review. KDP is more thorough with print files because physical printing costs are involved if something is wrong.
  • Hardcovers: Same timeline as paperbacks.

You will receive an email from KDP when your book goes live. Your KDP bookshelf will show the status change from “In Review” to “Live.” At that point, your Amazon product page is active and your book can be ordered by anyone on Amazon.

Link Your Paperback and eBook on One Listing

If you published both a Kindle eBook and a paperback, Amazon should automatically link them on the same product page within 24–48 hours of both being live. If they appear as separate listings after 72 hours, contact KDP support and ask them to manually link the formats. This happens occasionally, especially if the exact title or author name has even a small variation between the two uploads. KDP support links them quickly and without issue.

Set Up Your Author Central Page

After your book is live, go to author.amazon.com and claim your Author Central page. This is your author profile on Amazon — add a photo, biography, your social links, and your website. It appears on all your book listings. It costs nothing and takes 15 minutes, but it makes your books look significantly more legitimate to buyers who click through to check your other work.

Request Additional Categories

After publishing, email KDP support and ask for up to 8 additional categories (for a maximum of 10 total). Send them your book’s ASIN (found on your KDP bookshelf) and the exact category paths you want. This significantly increases your book’s discoverability across more keyword searches and bestseller lists.

Order a Proof Copy

If you did not order a proof copy before publishing, order one now. From your KDP bookshelf, click the button with three dots next to your paperback title and select “Order author copies.” Proof copies are printed at cost — your printing cost plus shipping. Read your proof cover to cover before running any marketing campaigns. Physical print can reveal issues that no digital preview catches.

Common KDP Upload Errors and How to Fix Them

These are the errors that trip up first-time KDP uploaders most often. All of them are fixable, but knowing what causes them ahead of time saves you from having to diagnose them under pressure after a rejection.

Manuscript Errors

Error: “Fonts not embedded”

Your PDF was exported without embedding the fonts. Open your source document (Word, InDesign, Canva), re-export as PDF, and make sure “Embed all fonts” or “PDF/A compliance” is selected in the export options. In Word: File → Save As → PDF → Options → check ISO 19005-1 compliant (PDF/A).

Error: “File dimensions do not match the trim size selected”

Your PDF page size does not match the trim size you chose in KDP. For example, your PDF pages are 8.5″×11″ but you selected 6″×9″ as the trim size. You need to reformat your manuscript to the correct page size and re-export. This requires going back to your source document. Our Paperback Formatter can apply the correct trim size dimensions to your uploaded PDF automatically.

Error: “Low resolution images detected”

One or more images in your manuscript are below 300 DPI. Find the image in your source document, replace it with a higher-resolution version, and re-export your PDF. Images that look perfectly sharp on a screen can still be low-resolution for print purposes — screen displays 72–96 DPI, print requires 300 DPI.

Warning: “Gutter margin may be too narrow”

Your inside margin is close to or below KDP’s minimum for your page count. For a 300-page book, the minimum gutter is 0.75″. Re-set your inside margin in your source document and re-export. Use the Gutter Calculator to find the exact minimum for your page count.

Cover Errors

Error: “Cover file dimensions do not match page count”

This is the most common cover rejection. Your cover PDF was designed with a spine width calculated for a different page count than your final manuscript. Recalculate your spine width using the Spine Width Calculator with your final page count, then adjust your cover design and re-export.

Error: “Text too close to cover edge”

Important text or design elements are within the 0.125″ bleed zone around the edges of your cover. KDP will flag this because elements that close to the edge risk being cut off after printing. Move all text and critical design elements at least 0.25″ away from the trim edges.

Error: “Cover file too large”

Your cover PDF is over KDP’s 400MB limit. This is uncommon but happens with very high-resolution photography-based covers. Flatten all layers in your design software, reduce image resolution to 300 DPI (not higher), and re-export.

FAQ

KDP Upload — Frequently Asked Questions

Common questions about uploading a book to Amazon KDP for the first time.

The upload process itself takes 20–40 minutes if your files are prepared and ready. After you submit, KDP reviews your book within 24–72 hours for Kindle eBooks and up to 5 business days for paperbacks. The total time from “I clicked Submit” to “my book is live on Amazon” is typically 1–3 days.
For paperbacks: a PDF with all fonts embedded, sized to your exact trim size (e.g. 6″×9″), with no security settings. For Kindle eBooks: EPUB is the current recommendation from Amazon — they deprecated MOBI in 2022. KDP also accepts DOCX (Word) and HTML for eBooks. Our free KDP Paperback Formatter prepares your PDF correctly for any KDP trim size.
The most common reasons for KDP rejection are: fonts not embedded in the PDF, wrong PDF dimensions for the selected trim size, cover spine width that does not match the manuscript page count, or low-resolution images under 300 DPI. KDP gives you specific error messages when a file is rejected — the error message tells you exactly what needs to be fixed. See our full rejection guide at KDP Rejection Guide for every error explained and fixed.
Yes, completely free. Publishing on Amazon KDP costs nothing upfront. There are no setup fees, no annual charges, no per-book costs until a copy sells. Amazon takes their percentage (40% for paperbacks, 30% for 70% plan eBooks) only when your book is purchased. The only costs you might have are tools, editing, or cover design — all of which are optional and separate from the KDP platform itself.
No. Amazon KDP automatically places the ISBN barcode on your back cover after you upload your files. You do not need to include a barcode in your cover design. Some designers leave a blank white space on the back cover where the barcode will go, but this is not required — KDP will overlay the barcode regardless of what design is underneath that area.
Yes. You can upload a new manuscript file, new cover, or update your description, keywords, and categories at any time from your KDP bookshelf. Changes typically go live within 24–72 hours. However, you cannot change the trim size, interior type (Black and White vs Color), or format (e.g. change a paperback to a hardcover) without creating an entirely new title listing. Changes to a live book do not affect existing orders — customers who already ordered receive the version that was live at time of purchase.
The process is the same as for paperbacks — log into kdp.amazon.com, click “Create a New Title,” and select “Kindle eBook” as your format. In Section 2, you upload your EPUB, DOCX, or HTML manuscript file instead of a PDF, and your cover as a JPEG (minimum 625×1000px, ideal 1600×2560px). For eBooks, there is no trim size to select because Kindle eBooks are reflowable — the text adjusts to the reader’s font size and screen. Use our free eBook Cover Resizer to size your cover to KDP’s requirements instantly.
