Kindle Direct Publishing (KDP) Guide for First-Time Authors
Amazon Kindle Direct Publishing is where most self-published books begin — and where most self-publishing careers are made or broken. With over 6 million titles in the Kindle store and Amazon controlling roughly 80% of ebook sales in the US, KDP is not one platform among many. It's the default.
This guide covers everything first-time authors need to know: account setup, manuscript formatting, cover specs, metadata, pricing strategy, royalties, and a launch day checklist. By the end, you'll have a clear roadmap from finished manuscript to published book.
What Is KDP and Why It Dominates Self-Publishing
Kindle Direct Publishing launched in 2007 alongside the original Kindle device. It was the first platform to let any author publish directly to a global bookstore without a publisher, agent, or distributor — and it changed the industry permanently.
Today, KDP offers:
- Ebook publishing — available globally within 24–72 hours of approval
- Paperback publishing — print-on-demand through KDP Print (formerly CreateSpace)
- Hardcover publishing — added in 2021 for standard trim sizes
- KDP Select — an exclusivity program that unlocks Kindle Unlimited enrollment and promotional tools
The reasons KDP dominates are practical: highest royalty rates in ebooks (up to 70%), print-on-demand with no upfront inventory costs, and direct access to Amazon's 300+ million active customer accounts. For a first-time author, the barrier to entry is essentially zero.
KDP Account Setup (Step-by-Step)
Before you can publish, you need a KDP account connected to valid tax and payment information.
Step 1: Go to kdp.amazon.com Sign in with your existing Amazon account or create a new one. A new account is often cleaner if you're publishing under a pen name.
Step 2: Enter your author/publisher information
- Legal name (for tax purposes — not necessarily your pen name)
- Address
- Phone number
Step 3: Set up tax information KDP requires a completed tax interview before you can receive royalties. US authors complete a W-9. Non-US authors complete a W-8BEN. This is mandatory and takes about five minutes. Without it, Amazon withholds 30% of your royalties.
Step 4: Add a bank account You'll need a bank account in a supported currency. KDP pays by direct deposit (US, UK, EU) or check. Payment threshold is $100 for wire transfers, $10 for direct deposit.
Step 5: Review your account settings Set your preferred marketplace (KDP.com covers the US, but your books are distributed globally by default).
Once your account is verified, you're ready to publish.
Manuscript Formatting Requirements
KDP accepts three manuscript formats: Word (.docx), PDF, and ePub. Each has trade-offs.
Word (.docx) — Recommended for Most Authors
KDP converts Word files into Kindle format automatically. For best results:
- Use built-in Word styles (Heading 1, Heading 2, Normal) rather than manual formatting
- Set page size to 6" × 9" or your trim size of choice
- Use a serif font (Georgia, Garamond) at 11–12pt for body text
- Remove headers and footers — KDP generates its own
- Embed a clickable Table of Contents using Word's TOC generator
- Set paragraph spacing: 0pt before, 6–12pt after, with 0.3–0.5" first-line indent
- No tab indents — use paragraph indent settings instead
ePub — Best for Complex Layouts
If your book has unusual formatting, sidebars, or complex typography, exporting to ePub from a dedicated tool (Vellum, Atticus, Sigil) gives you more control. KDP accepts ePub 2 and ePub 3.
PDF — For Print Only
For KDP Print paperbacks, PDF is the standard. Use your trim size exactly, embed all fonts, and export at 300 DPI. PDFs uploaded for ebook are sometimes accepted but often produce poor results.
Cover Specifications
Your cover is the most important marketing asset your book has. On Amazon, it appears as a thumbnail — roughly 100 × 160 pixels — before a reader ever reads the title. Design for thumbnail clarity first, full-size detail second.
Ebook Cover
- Dimensions: 2,560 × 1,600 pixels (1.6:1 ratio) — this is the ideal
- Minimum: 1,000 × 625 pixels
- Format: JPEG or TIFF
- File size: Under 50MB
- Resolution: 72 DPI is fine for screen; 300 DPI future-proofs it
Paperback Cover (Full Wrap)
Paperback covers include front, back, and spine. KDP provides a cover template calculator at kdp.amazon.com/cover-calculator — use it. Input your trim size, page count, and paper color to get exact dimensions with bleed marks.
Key rules:
- Add 0.125" bleed on all sides
- Keep text 0.25" from the trim line
- Spine width is calculated by KDP based on page count (roughly 0.002252" per page for cream paper)
- Barcode placement: KDP places the ISBN barcode automatically on the back cover — leave a 2" × 1.2" white area in the lower right
Metadata: Title, Subtitle, Keywords, and Categories
KDP metadata is the foundation of your Amazon discoverability. Get this wrong and even a great book stays invisible.
Title and Subtitle
Your title and subtitle are locked after publication. Enter them exactly as they appear on your cover. Adding keyword stuffed titles ("The Best Mystery Novel Ever: A Thrilling Murder Mystery That Will Keep You Up At Night") violates Amazon's Terms of Service and risks account suspension.
Your subtitle is metadata real estate — use it for genre clarity and reader expectation-setting, not keyword cramming.
The 7 Keyword Slots
KDP gives you seven keyword fields. These are search terms Amazon uses to surface your book. Best practices:
- Use phrases, not single words ("cozy mystery with cats" beats "mystery")
- Avoid repeating words already in your title or categories
- Use terms readers actually type, not industry jargon
- Test your phrases in Amazon's search bar — the autocomplete shows real queries
- Update keywords anytime from your KDP dashboard — you're not locked in
BISAC Categories
KDP lets you select two browse categories. These determine where your book appears in Amazon's category ranking system (the "#1 Bestseller" badge comes from ranking #1 in a category).
Strategic category selection:
- Choose the most specific relevant subcategory, not the broad genre
- One competitive category (where your audience already browses) + one niche category (easier to rank in)
- Research competing books' categories before choosing
Pricing Strategy: 35% vs. 70% Royalty
KDP's royalty structure is simple but critical to understand before you set your price.
The 70% Royalty Window
To earn 70% royalties, your ebook must be priced between $2.99 and $9.99. Outside this range, your royalty drops to 35%.
The 70% rate is calculated on the list price minus delivery costs (a small fee based on file size, typically $0.01–$0.15). For a $4.99 ebook, you earn roughly $3.45 per sale.
When 35% Makes Sense
- Perma-free books (Series starters, reader magnets) — price at $0.00 or $0.99 to maximize volume
- Very long books with high file sizes where delivery costs eat into 70% royalties
Practical Pricing Guidelines
- Debut fiction: $2.99–$4.99 (lower barrier, easier to build audience)
- Nonfiction / how-to: $4.99–$9.99 (readers expect to pay for practical value)
- Series book 1: Consider $0.99 or free to drive read-through to later books
- Paperbacks: Use KDP's suggested pricing (based on print cost + margin) as your floor
KDP Select vs. Wide Distribution
This is the most consequential decision a new KDP author makes.
KDP Select (Exclusive)
Enrolling in KDP Select means your ebook is exclusive to Amazon for 90-day renewable terms. In exchange, you get:
- Kindle Unlimited enrollment — subscribers can borrow your book; you earn per page read (KENP rate, currently ~$0.0045 per page)
- Kindle Countdown Deals — limited-time price promotions with higher royalty rates
- Free Book Promotions — up to 5 free days per 90-day period to generate downloads and reviews
KDP Select is worth it if:
- You're in a genre with high KU readership (romance, fantasy, thriller, sci-fi)
- You're building a series and want maximum exposure on the first book
- You're a new author with no established audience elsewhere
Wide Distribution
Going "wide" means publishing on Amazon plus Kobo, Apple Books, Barnes & Noble, Google Play, and library platforms (OverDrive, Hoopla). Wide distribution is typically done through aggregators like Draft2Digital or PublishDrive.
Wide is worth it if:
- You have an established audience on non-Amazon platforms
- You write nonfiction (which performs more evenly across platforms)
- You want platform diversification for long-term business resilience
Most debut fiction authors should start with KDP Select. You can go wide after your first 90-day term.
Pre-Order Setup and Launch Day Checklist
Setting Up a Pre-Order
KDP allows pre-orders up to 12 months before publication. Pre-order sales count toward your first day's sales rank — crucial for rankings and category bestseller badges.
To set up a pre-order:
- Start a new title in KDP, select "Set publication date in the future"
- Upload a cover and fill all metadata — the manuscript can be a placeholder
- Upload your final manuscript at least 72 hours before publication date
- Your pre-order listing goes live within 24–72 hours
Launch Day Checklist

KDP Dashboard: Sales Reports, KENP Reads, Royalty Tracking
Your KDP dashboard is your business command center. Key sections:
Sales Dashboard
Shows real-time unit sales by title, marketplace, and format. Updated hourly. Use the date range filter to compare week-over-week performance.
KENP Reads
If you're in KDP Select, this shows the number of Kindle Unlimited pages read. The payout per page varies monthly — Amazon announces the KU Global Fund payout rate in the month following. You can estimate earnings by multiplying KENP reads × ~$0.0045.
Royalties
The Royalties tab shows estimated earnings. Note: KDP pays approximately 60 days after the end of the month in which sales occur. A January sale pays out at the end of March.
Prior Months' Royalties
Download royalty reports as CSV for your accounting records. Essential at tax time.
Common Mistakes First-Time KDP Authors Make
1. Publishing before the cover is ready. A placeholder cover kills launch momentum. The cover is the single highest-ROI investment you can make.
2. Ignoring categories. Most authors pick the broadest possible category. Picking a niche subcategory where you can rank #1 is worth far more for discoverability.
3. Writing the description last. Your book description should be written — and revised — before you publish, not as an afterthought. It's your sales page.
4. Not enrolling in Author Central. Author Central (author.amazon.com) lets you claim your author page, add an editorial review, link all your books, and add a bio. It takes 20 minutes and is free.
5. Uploading a Word file with manual formatting. Manual bold used for headings, tabs for paragraph indents, and custom fonts embedded in Word all produce broken Kindle files. Use styles.
6. Setting the wrong price at launch. You can change your price at any time, but launch pricing affects initial velocity. Don't price a debut novel at $9.99 — the barrier to trial is too high.
7. Forgetting print. Many KDP authors focus entirely on ebooks and skip the paperback. But paperbacks boost credibility, enable in-person sales, and open library markets. KDP Print is free.

The Bottom Line
KDP is the most powerful distribution channel available to self-published authors — and it's free to use. But publishing well on KDP is a craft: the formatting, metadata, cover, pricing, and launch timing all compound into a result that either builds momentum or wastes it.
Get the basics right. Cover first. Metadata second. Launch checklist third. And if you're building a series, make KDP Select decision number one — not an afterthought.
The authors who build careers on KDP aren't the ones with the most talent. They're the ones who treat publishing like a system and execute it reliably.
