Kindle vs Paperback: Should You Do Both on Amazon KDP?

The short answer is yes. But the why matters, because doing both badly is worse than doing one well.

This is one of those questions that sounds like a formatting decision but is actually a sales decision. Kindle vs paperback on KDP isn't really about your personal preference for reading — it's about how different readers buy, what signals a professional publication, and how Amazon's algorithm treats books that have both formats versus those that don't. Get it right and the two versions work together. Get it wrong and you've added work without adding results.

First-time authors tend to default to ebook-only because it feels simpler and cheaper. And it is simpler. But "simpler" and "better for your launch" are two very different things, and conflating them costs a lot of debut authors sales they didn't know they were leaving behind.

Before we get into the mechanics, if you want a clear plan for how to launch whichever format combination you choose, The 5-Day Book Launch Kit by Arroe Murphy lays it out day by day — but understand the format question first, because it shapes your launch strategy.

What Kindle and Paperback Actually Are on KDP

Quick grounding, because the terminology trips people up.

When authors talk about "Kindle" publishing on KDP, they mean the ebook format — a digital file that readers download to a Kindle device or the free Kindle app on any phone or tablet. The file is formatted for reflowable text, meaning the layout adjusts to the reader's font size and screen. You upload the manuscript, KDP converts it, and it's available to buy within 24 to 72 hours of approval.

Paperback through KDP is print-on-demand. Amazon prints a physical copy only when someone orders one. No boxes of unsold stock in your spare room. No upfront printing costs. The book exists as a file until someone buys it, at which point Amazon prints and ships it directly to them. You get your royalty, Amazon keeps theirs, and the whole thing runs without you touching it.

Both formats end up on the same Amazon product page once linked — a buyer can choose between Kindle edition and paperback from a single listing. That combined listing is more powerful than either format alone, and it's one of the clearest reasons to do both.

The Case for Ebook-Only (And Why It Usually Isn't Enough)

There are situations where starting with Kindle only makes genuine sense.

If your book is heavily time-sensitive — a guide tied to a current event, a topical essay collection — getting it live fast matters more than having print available. Ebook-only gets you there quickest. If you're testing an idea with a very short piece (under 100 pages), print-on-demand economics can get awkward because the minimum printing cost eats into your royalty at low price points, making it hard to price competitively.

And if your audience is predominantly digital — tech-forward readers, people who read primarily on devices — the print version might genuinely sell so few copies that it's not worth the formatting time.

But for most non-fiction and fiction authors launching on Amazon KDP? Ebook-only leaves real money on the table. According to a 2023 survey by the Alliance of Independent Authors, indie authors who published both formats consistently reported 30 to 40% higher overall revenue than those who published ebook only. The print version doesn't just add print sales — it changes how the listing looks, how readers perceive the book's legitimacy, and in some cases how Amazon's algorithm treats it.

That last part is the one most authors don't expect.

How Having Both Formats Changes Your Amazon Listing

When you publish both a Kindle and a paperback edition through KDP and link them correctly, Amazon combines them into a single product page. The listing shows both options, the reviews are shared across formats, and the book's overall sales rank draws from both versions.

That shared review pool matters more than it sounds. A paperback buyer leaving a five-star review boosts the same listing that Kindle buyers see. A reader who buys the ebook and loves it can leave a review that shows up for the print browser. The social proof compounds instead of splitting across two separate pages with separate review counts.

There's also a perception piece that's hard to quantify but very real. A book with a paperback edition looks finished in a way that ebook-only sometimes doesn't. For non-fiction especially, readers making a purchase decision often check whether a print version exists — not because they necessarily plan to buy it, but because its existence signals that the author took the project seriously enough to go through the full production process. Right or wrong, that perception affects conversion rates on the ebook too.

Kindle vs Paperback Royalties: Running the Numbers

This is where format choice gets genuinely practical, so let's be specific.

Kindle royalties: KDP pays either 35% or 70% of the list price, depending on where you price it. Books priced between $2.99 and $9.99 earn 70%. Everything below $2.99 or above $9.99 earns 35%. A Kindle edition priced at $4.99 earns you roughly $3.49 per sale. Simple.

Paperback royalties work differently. KDP takes a printing cost off the top before calculating your royalty. The royalty rate is 60% of the amount left after printing. Printing cost depends on page count and interior type — a standard 250-page black-and-white paperback costs approximately $3.50 to print for the US market. So a paperback priced at $14.99 earns you 60% of ($14.99 minus $3.50) — about $6.89 per sale.

The practical upshot: paperback royalties per unit are often higher than ebook royalties per unit, assuming sensible pricing on both. Which flips the assumption a lot of first-time authors have. They think ebook is where the money is because there's no printing cost. But 70% of $4.99 is $3.49. And 60% of ($14.99 minus $3.50) is $6.89. The print book earns more per sale — it just sells fewer units than the ebook in most cases.

Both formats earning simultaneously is how you get the best of both.

The Formatting Reality Nobody Warns You About

Here's where a lot of authors hit an unexpected wall: the files for Kindle and paperback are not the same, and you can't use one for both.

Your Kindle file needs to be formatted for reflowable text. Most authors use a .docx file or export from Scrivener, Vellum, or Atticus. The text reflows to fit any screen size, which means you can't rely on fixed page breaks or precise visual layouts.

Your paperback file needs to be a print-ready PDF with fixed dimensions, correct margins (inner margins wider than outer to account for the spine), proper bleed settings if your cover extends to the edge, and a spine width calculated from your exact page count. Submitting a Kindle-formatted document as your print file is one of the most common reasons KDP rejects print uploads.

The cover is a separate issue entirely. Your Kindle cover is a flat image — front cover only, standard dimensions. Your paperback cover needs to wrap around the entire book: front, spine, and back, sized precisely to your page count and paper type. KDP provides a cover template calculator that generates the exact dimensions once you know your final page count and paper choice.

None of this is beyond a first-time author. But it does take longer than people budget for, and discovering it the week of your planned launch is a genuinely stressful experience. Build the formatting time in early.

What This Means for Your Launch

Publishing both formats isn't just a product decision. It changes how you plan your launch.

If you're launching both simultaneously, you need both files finished and approved before your publish date — which means starting the print formatting process at least two to three weeks out, not the day before. KDP can take up to 72 hours to approve a print book, sometimes longer if there are cover or file issues flagged. A Kindle launch is faster, but a combined launch that actually goes live when you planned requires lead time on the print side.

There's also a sequencing question some authors don't consider: launching ebook first, then adding paperback a week or two later, splits your early momentum. The reviews you gather in week one on the Kindle edition don't automatically carry over if the print version launches as a separate listing before you link them. Getting the linking right — and doing it before either version goes live if possible — makes the combined listing work from day one rather than needing to be fixed after.

This is the kind of detail that separates authors who get a strong first week from those who spend it troubleshooting. The 5-Day Book Launch Kit by Arroe Murphy covers exactly this sequencing — the specific actions, in the right order, across the days around your launch — so the format combination you've worked to set up actually performs the way it should. For first-time KDP authors trying to hold all of this together at once, that kind of day-by-day clarity is genuinely useful.

So: Kindle, Paperback, or Both?

Both. For most authors, almost always both.

The ebook reaches readers who buy digitally, travels with them everywhere, and earns royalties at a price point that feels low-risk to a reader who doesn't know you yet. The paperback sits on the same listing, signals legitimacy, earns a higher royalty per unit, and captures the readers who simply prefer physical books — a group that is, despite everything, still enormous.

The formatting takes more work. The lead time is longer. But a combined Kindle and paperback listing on launch day is a fundamentally stronger product page than either format alone — and a stronger product page converts better, ranks better, and builds the kind of early momentum that Amazon's algorithm rewards.

Do the formatting work early. Get both versions approved before your launch window. Link them correctly from the start. Then focus everything on making that first week count.
