Kindle KDP Guide: Ebook & Paperback Publishing

Okay so I just walked someone through their first KDP upload last week and realized there’s still so much confusion about the basics, so lemme break this down the way I wish someone had explained it to me back in 2017.

Setting Up Your KDP Account

First thing – you need an Amazon account, obviously. But here’s what people mess up: use a separate email from your regular Amazon shopping account if you can. Makes tracking royalty emails and promotional stuff way easier. You’re gonna need tax info right away, and yeah, it’s annoying but just power through it. W-9 if you’re in the US, W-8BEN if you’re international. Amazon holds your royalties until this is done, so don’t skip it thinking you’ll come back to it later.

The tax interview takes like 10 minutes. Have your SSN or EIN ready. International folks, you’ll need your tax ID number from your country. One thing that tripped me up early on – if you’re doing this as a business, get an EIN even if you’re a sole proprietor. Makes everything cleaner come tax season.

Ebook vs Paperback – The Actual Differences That Matter

So ebooks are obviously easier to start with. No print costs, no inventory, you can update files whenever you want. I still remember my first ebook had a typo on page 3 and I literally fixed it in five minutes and reuploaded. Try doing that with 500 paperbacks sitting in Amazon’s warehouse.

Paperbacks though… they just convert better for certain niches. Journals, planners, workbooks, kids books – people want physical copies. Your royalty is gonna be way less because Amazon deducts printing costs, but the perceived value is higher so you can charge more.

Print costs depend on page count and whether you do black/white or color. A 120-page black and white paperback costs Amazon like $2.50 to print. Color? More like $4-5 for the same page count. This is why most low-content books stay black and white inside even if the cover’s in color.

File Formats You Actually Need

Ebooks need to be either EPUB, DOC, DOCX, or MOBI. I always use EPUB because you have the most control. Word docs work fine for simple text-based books, but the second you add images or special formatting, you’re gonna have issues. There’s this free tool called Calibre that converts everything to EPUB – I’ve used it for probably 150+ books at this point.

For paperbacks, it’s PDF only. And not just any PDF – it needs to be press-ready. That means embedded fonts, CMYK color mode (not RGB), and the right trim size. I spent three days troubleshooting a file once because I forgot to embed fonts and Amazon’s system kept rejecting it.

Creating Your Ebook File

Okay so for ebooks, you gotta think about how they’ll display on different devices. A Kindle Paperwhite, a Fire tablet, the iPhone app – they all render slightly different. Keep your formatting simple. Seriously. I see people trying to get fancy with text boxes and columns and it just breaks on mobile.

Use styles in Word if you’re going that route. Heading 1 for chapter titles, Normal for body text. Don’t just make text bigger and bold manually – actually use the style system. This creates a proper table of contents that Amazon’s system can read.

Images should be JPG or PNG, under 5MB each, and honestly I keep mine under 1MB because larger files mean longer download times and Amazon can charge customers for delivery costs on files over a certain size, which comes out of YOUR royalty. Yeah, it’s like 15 cents per megabyte or something but it adds up.

Oh and another thing – your cover image for ebooks needs to be at least 1600 pixels on the shortest side. I usually do 1600×2560 because that’s the ratio Amazon recommends. It’ll look tiny in the thumbnail but trust me, people do zoom in to check out covers.

Paperback Formatting Is Where It Gets Real

This is where I see most beginners struggle. Your paperback needs margins for the gutter (that’s the spine area where pages get bound). For a 6×9 book, I usually do 0.75″ on the inside margin, 0.5″ on outside, top, and bottom. Amazon has templates you can download – USE THEM. Don’t try to wing it.

Bleed is another thing. If your cover or interior has images or colors that go to the edge of the page, you need to add 0.125″ bleed on all sides. This means your design actually extends past the trim line so when the book gets cut, you don’t end up with white edges.

I learned this the hard way when I ordered an author copy of a coloring book and every page had these thin white borders because I didn’t set up bleed correctly. Had to redo the entire interior file.

Your paperback file dimensions need to match your chosen trim size exactly. If you pick 6×9, your PDF needs to be 6×9. Seems obvious but I’ve seen people mess this up by accidentally exporting at letter size or something.

Cover Creator vs Custom Covers

Amazon has this Cover Creator tool that’s honestly not terrible for basic text-based books. You pick a template, upload a background image if you want, add your title and author name. It automatically generates the spine and back cover based on your page count.

For anything you actually want to sell though, get a custom cover. You can use Canva, hire someone on Fiverr for like $20-50, or learn to use Photoshop yourself. Your cover is literally the first thing people see – it needs to not look like garbage.

For paperbacks, you need to download the cover template from KDP after you enter your page count. It’ll give you exact dimensions including the spine width. A 200-page book has a thicker spine than a 100-page book, obviously. The template shows you where the barcode goes (back cover, bottom right), and where the trim lines are.

Uploading to KDP – The Actual Process

Hit the “+ Create” button and choose Kindle eBook or Paperback. You can’t do both in one upload – they’re separate products, but you can link them later.

Enter your book details:

• Title (60 characters max but shorter is better)
• Subtitle if you have one
• Author name (use a pen name if you want, doesn’t matter)
• Description (up to 4000 characters – use HTML formatting here, most people don’t know this)
• Keywords (7 boxes, use all of them, be specific)
• Categories (pick 2, but you can email KDP to get up to 10 total)

Wait I forgot to mention – your description can include basic HTML tags like bold, italics, bullet points. Makes it look way more professional than just a wall of text. I use tags for highlighting key benefits and

lists to break up features.

For keywords, don’t just use single words. Use phrases people actually search for. Instead of “recipes,” try “easy dinner recipes for beginners” or “quick weeknight meals.” Amazon’s algorithm looks for exact matches and close variations.

Pricing Strategy That Actually Works

Ebooks enrolled in KDP Select (more on that in a sec) earn 70% royalty if priced between $2.99-$9.99. Outside that range, it’s 35%. Most of my ebooks sit at $4.99 or $5.99 – high enough to make decent money but low enough that people impulse buy.

Paperbacks, you gotta calculate based on printing costs. Amazon shows you the minimum price that covers their printing + gives you a small royalty. I usually add $3-5 on top of that. So if minimum is $6.50, I’ll price at $9.99.

Here’s something weird but it works – prices ending in .99 convert better than round numbers. $4.99 outsells $5.00 even though it’s literally one cent different. Human psychology is weird.

KDP Select vs Going Wide

KDP Select means your ebook is exclusive to Amazon for 90 days. In exchange, you get:

• Access to KDP Countdown Deals and Free Book Promotions
• Inclusion in Kindle Unlimited (you get paid per page read)
• 70% royalty in more countries

Going wide means you publish on other platforms too – Apple Books, Kobo, Google Play, etc. You make less per sale usually but you reach more readers.

I do KDP Select for new launches because the promo tools help with initial visibility. After a few months, if the book isn’t performing, I’ll let it expire and go wide. There’s no right answer here – it depends on your goals and genre.

Getting Your Book Live

After you upload everything and hit publish, Amazon reviews your book. Ebooks usually go live within 24-72 hours. Paperbacks can take up to 5 days because they check the print file more carefully.

Order an author copy before you approve the paperback for distribution. Costs like $3-4 plus shipping. This lets you see the actual physical book and catch any issues. I’ve found formatting problems, color issues, cover misalignments – stuff you can’t see in the online previewer.

Oh and funny story – my cat knocked over my coffee onto my keyboard while I was uploading a book once and I accidentally set the price at $0.99 instead of $9.99. Didn’t notice for two days and sold like 40 copies before I caught it. Lost probably $200 in royalties but hey, got some early reviews out of it.

Linking Ebook and Paperback Editions

Once both formats are live, Amazon usually links them automatically within a few days. Sometimes it doesn’t happen though. You can contact KDP support and ask them to link the editions manually. Give them both ASINs and they’ll do it.

Why does this matter? Because it shows customers both formats on one product page. Looks more professional and some people prefer physical books even if they usually buy ebooks.

Marketing Tools Inside KDP

Amazon has built-in promo tools that most people underuse. If you’re in KDP Select:

Kindle Countdown Deals: Discount your book for up to 7 days. The price gradually increases back to normal. You keep 70% royalty even if you drop to $0.99, which is huge.

Free Book Promotion: Make your ebook free for up to 5 days per enrollment period. Great for getting reviews and visibility. I usually do 2-3 day free runs.

For paperbacks, you can run “expanded distribution” which gets your book into bookstores and libraries potentially. Honestly I’ve never made significant money from this but it’s free to opt in so why not.

Common Mistakes I Still See

Not using all 7 keyword boxes. Like why would you leave free advertising space empty?

Choosing the wrong categories. If your book is in “Crafts & Hobbies > General” you’re competing with 500,000 books. Drill down to something specific like “Crafts & Hobbies > Papercrafts > Origami” and suddenly you’re in the top 100.

Uploading the wrong file format. Amazon accepts PDFs for paperback interiors but they need to be the right kind of PDF. Export from Word using “PDF/A” or “Press Quality” settings.

Not checking the preview before publishing. The online previewer shows you exactly how your book will look. Use it. I’ve caught typos, formatting issues, missing pages – all stuff that would’ve been embarrassing if customers saw it.

Pricing too low because you think it’ll sell more copies. Race to the bottom doesn’t work. Price based on value and what comparable books cost. A $0.99 ebook looks like low-quality garbage to most shoppers.

After Your Book Goes Live

Get reviews however you can. Send copies to friends, post in Facebook groups (where allowed), use your email list. Reviews matter way more than you think for visibility in Amazon’s algorithm.

Run promotions regularly if you’re in KDP Select. A free day every month or two keeps your book fresh in the algorithm and can lead to a sales bump afterward.

Update your keywords and description based on what’s working. Check your KDP dashboard to see what search terms are driving sales, then optimize around those.

The reports section shows you sales by marketplace, which formats are selling, even which promo tools drove the most downloads. Actually look at this data instead of just watching your total royalties go up (or not).

You can update your book files anytime. Fixed a typo? Upload a new file. Want to add a chapter? Do it. Ebooks propagate to customers automatically, paperbacks only affect new orders obviously.

Anyway that’s the core stuff you need to know to get started. There’s more advanced strategies like using Amazon Ads, building a series, optimizing for also-boughts, but honestly just getting your first book published and seeing how the system works is the important part. Everything else you can figure out as you go.
