Going Wide vs KDP Select: Which Should Self-Publishers Choose?

KDP Select makes your ebook exclusive to Amazon for 90-day terms. In return, you get Kindle Unlimited page-read income and some promotional tools. Going wide means selling the same ebook through Apple Books, Kobo, Google Play Books, Barnes & Noble and library platforms, so you give up those Amazon perks in exchange for more storefronts and less dependence on one company.

Neither option is better for every book. Select tends to suit fast-releasing genre fiction whose readers already use Kindle Unlimited. Wide suits authors who want a long-term readership across many stores and countries.

	KDP Select (exclusive)	Going wide
Where your ebook sells	Amazon Kindle only	Amazon plus Apple Books, Kobo, Google Play Books, Barnes & Noble and others
Exclusivity	Ebook can't be sold or given away in digital form anywhere else	None. You choose every store
Subscription income	Kindle Unlimited page reads (KENP)	Some store subscriptions, such as Kobo Plus, if you opt in
Promotion tools	Kindle Countdown Deals or Free Book Promotions in each term	Store-run promotions and your own price changes on each platform
Ebook royalty on Amazon	Standard KDP rates (70% for $2.99–$9.99 under KDP's published terms, otherwise 35%)	Same standard KDP rates
Royalty elsewhere	None, because you can't sell elsewhere	Each store's own rate, often around 70% in a set price band (verify in each dashboard)
Libraries	Not available for the ebook	Available through Kobo, Draft2Digital and other library platforms
Paperback and hardcover	Not affected. Print can be sold anywhere	Not affected
Commitment	90-day terms that renew automatically unless you turn renewal off	No lock-in
Admin work	One dashboard	Several dashboards, or one aggregator
Main risk	All ebook income depends on Amazon's rules and the monthly KU payout	Slower start, with sales split thinly across stores at first

What KDP Select actually requires

KDP Select is an optional program for Kindle ebooks. When you enroll, you agree that the digital version of that book is available only through Amazon for the length of the term. Each term is 90 days, and enrollment renews automatically unless you untick the renewal box on your KDP Bookshelf.

Exclusivity covers the ebook in any digital form. That includes your own website, a newsletter giveaway, a PDF on a course platform, and every other ebook store. A short sample is allowed. Check the current limit in the KDP Select terms before you post an excerpt.

In exchange, your book is:

• Included in Kindle Unlimited. Subscribers read it at no extra cost, and you're paid from a monthly fund based on pages read, measured in KENP. The per-page rate changes every month, so check recent figures in your KDP reports rather than relying on a number you saw quoted online.
• Eligible for promotions. You can run a Kindle Countdown Deal (a timed discount) or a Free Book Promotion during each term. Under the current terms you pick one type per term, and Countdown Deals only run in certain marketplaces.

Print editions are not part of Select. Your paperback can be on KDP, IngramSpark or anywhere else while the ebook is enrolled. For a fuller breakdown of the program, see what KDP Select is and how it works.

What "going wide" means in practice

Going wide means your ebook is available in more than one store. Most wide authors publish to:

• Amazon Kindle through KDP, without Select enrollment
• Apple Books through Apple Books for Authors
• Kobo through Kobo Writing Life, which also offers library distribution and opt-in to Kobo Plus
• Google Play Books through Partner Center
• Barnes & Noble through B&N Press
• Libraries through platforms such as OverDrive, reached via Kobo or an aggregator

There are two ways to do this. You can upload directly to each store, which gives you the full store royalty and direct access to store promotions. Or you can use an aggregator like Draft2Digital, which sends one upload to many stores and library platforms and takes a fee. D2D's published fee is about 10% of list price, but confirm the current fee on their site. Many authors mix the two approaches: they go direct to Amazon, Apple and Kobo, then use an aggregator for smaller stores and libraries.

None of these stores require an ISBN for ebooks, according to their published terms. Draft2Digital can assign a free one if you want it. Print is different: a B&N print edition, for example, needs an ISBN.

How royalties compare between Select and wide

On Amazon itself, your sales royalty is the same either way. KDP's published terms pay 70% for list prices from $2.99 to $9.99, minus a delivery fee, and 35% outside that range. KDP has also offered the 70% rate in a few marketplaces only to Select-enrolled books, so check the current list in your dashboard if you sell heavily in those countries.

The real difference is where your other income comes from.

• In Select, the second income stream is Kindle Unlimited page reads. For long books in genres where readers binge, KU can earn more than sales do. For short books, or genres with few KU readers, it may add little.
• Wide, the second stream is sales from other stores and libraries. Apple Books, Google Play Books, Kobo and B&N each list royalties of around 70% within their price bands. Kobo, for example, states 70% at $2.99 and above and 45% below. Verify each one in its own dashboard, because these are estimates and the terms change.

You can model Amazon earnings at different prices with the KDP royalty calculator. Remember that a KU borrow and a sale pay out very differently, so compare actual reports over several months rather than single days.

When to choose KDP Select

Select often makes sense when:

• Your genre lives in Kindle Unlimited. Romance, thrillers, fantasy, science fiction and other binge-read genres tend to have heavy KU readership. Check the top of your category on Amazon. If most top books carry the Kindle Unlimited badge, your readers are probably there.
• You release often. KU readers move from book to book quickly, and a steady release schedule keeps page reads coming.
• You write long books or series. Longer books earn more pages read per borrow, and series encourage readthrough. If you're planning one, read about how to write a book series.
• You want one dashboard. If you have limited time for admin, managing a single store is simpler.
• You're testing a debut. Some authors use Select for a few terms to get visibility, then reassess.

When to go wide

Wide often makes sense when:

• Your genre isn't KU-heavy. Much non-fiction, literary fiction, poetry and niche topics see fewer KU borrows. In that case exclusivity costs you more than it pays.
• You want readers outside the US. Apple Books, Kobo and Google Play Books have strong audiences in various countries where Kindle is less dominant.
• You want library income and discovery. Library platforms are closed to Select ebooks.
• You sell directly. If you want to sell ebooks from your own site, bundle them with a course, or give them to newsletter subscribers, Select's exclusivity rules that out.
• You don't want one point of failure. A policy change, an account issue or a drop in the KU payout affects all your ebook income when you're exclusive.
• You're building for the long term. Wide sales usually start slowly and grow as you add books and learn each store's promotions.

Using Select for some books and going wide with others

Select works book by book, not account by account, so mixing is allowed. Some authors keep one series in KU and publish another series wide. Others put a standalone in Select to test it.

The trade-off is reader confusion. A Kobo reader who finds book one of a series and then can't buy book two will be frustrated. If you split, split by series or pen name, not within a series.

Switching from KDP Select to wide

1. Turn off auto-renewal. On your KDP Bookshelf, open the book's KDP Select options and untick automatic renewal. The book stays enrolled until the current 90-day term ends.
2. Note the end date. Don't publish elsewhere before that date, because doing so breaks the agreement.
3. Prepare your files and store accounts during the remaining weeks. Most stores accept EPUB and a JPG or PNG cover around 1600 × 2560 px. If you wrote your book in Inkora, the EPUB 3 export and the 1600 × 2560 Kindle cover JPG work for the main stores, and the ONIX 3.0 metadata export can help with stores and aggregators that accept it.
4. Publish wide after the term ends. Go direct, use an aggregator, or combine both. Inkora's Publishing Hub has step-by-step checklists for Apple Books, Google Play Books, Kobo, Barnes & Noble Press and Draft2Digital. You still upload in your own accounts.
5. Tell your readers. Let your newsletter and social followers know the book has left Kindle Unlimited and where to buy it now.

Moving a wide book into KDP Select

1. Unpublish everywhere else. Remove the ebook from every store, aggregator and library platform, and take down any direct-sale or giveaway copies.
2. Confirm it's actually gone. Stores can take days or longer to remove a listing. Search each store for the title before you enroll.
3. Enroll in KDP. Open the book's KDP Select page and enroll. The 90-day term starts right away.
4. Keep records. Save confirmation emails and screenshots showing you removed the book, in case Amazon later finds an old copy.

Library copies already bought by a library may stay in its catalog after you unpublish. Contact the platform or aggregator you used and ask how they handle this before you enroll.

Common problems and fixes

The book still shows on another store after you unpublished. Retailer listings can lag. Contact that store's support or your aggregator, keep a screenshot of your removal request, and wait until the listing is gone before enrolling in Select.

Amazon emails you about an exclusivity violation. This usually means an old copy is live somewhere, sometimes on a pirate site. Find and remove it, file takedowns for pirated copies, and reply to KDP with what you did and when. Respond promptly.

You forgot to turn off auto-renew. Your book is locked in for another 90 days. Use the time to set up your wide accounts and files, and put a reminder in your calendar a couple of weeks before the next term ends.

Wide sales are tiny at first. This is normal. Apple, Kobo and Google readers often find books through store promotions, series and new releases. Apply for promotions in each dashboard where they're offered, keep publishing, and judge results over several months.

Amazon rank drops after leaving KU. Losing KU borrows lowers your sales rank on Amazon. Plan the switch for a time when you can announce it to your readers or run a price promotion across stores.

Amazon lowers your price. Amazon may price-match a lower price it finds elsewhere, which can change your royalty band. Keep list prices consistent across stores unless the discount is deliberate.

You're not sure which option is working. Compare total ebook income, including sales, page reads and other stores, across equal time periods. A single launch week tells you little.

Pick the option that fits where your readers buy and how often you release, not the one that looks better in someone else's screenshot. You can switch in either direction at the end of a term, so treat your first choice as a test. Then decide using several months of your own reports.
