This is the single biggest distribution decision you'll make, and most guides dodge it. Here's the straight answer.
What you're actually choosing between
KDP Select makes your ebook exclusive to Amazon for 90-day terms. In return you get: Kindle Unlimited page-read royalties, Kindle Countdown Deals, and free-promo days.
Wide means your ebook sells everywhere — Apple Books, Kobo, Barnes & Noble, Google Play, plus libraries and Bookshop.org — usually via an aggregator like Draft2Digital.
Important: this only affects the ebook. Your print book isn't locked to Amazon either — you can (and should) distribute it wide via IngramSpark (or KDP's Expanded Distribution), regardless of your ebook choice.
Choose KDP Select if...
- You write genre fiction in series — romance, thriller, fantasy, sci-fi, LitRPG, cosy mystery.
- Your readers are heavy Kindle Unlimited subscribers (they are, in those genres).
- You're launching book one of a series and want page-reads to compound across the series.
- You'll actively use the free-promo and Countdown tools to drive series reads.
For these authors, KU page-read income can, for the right series, exceed what wide sales would earn, and the promo tools are genuinely useful.
Go wide if...
- You write non-fiction, literary fiction, memoir, or children's — readers buy these outright, not via KU.
- You want library and bookshop reach — a huge market KDP Select locks you out of.
- You sell direct or have an international readership strong on Apple/Kobo (Kobo is big in the UK, Canada, and beyond).
- You're building a durable catalogue and don't want your income hostage to one retailer's algorithm changes.
The honest middle path
Many authors start a series in KDP Select to build momentum, then go wide once the series is established and they want library/bookshop reach. That's a legitimate strategy — just remember each KDP Select term is 90 days, and you must turn off auto-renew before going wide.
Verdict
There's no universal right answer — it's genre-dependent. Series genre fiction → KDP Select. Everything else → wide. If you're unsure, ask one question: do my readers live in Kindle Unlimited? If yes, Select; if no, wide.
Frequently asked questions
Does KDP Select affect my paperback?
No — only the ebook. Your print book can be wide (via IngramSpark) even while the ebook is in KDP Select.
Can I switch from KDP Select to wide later?
Yes. KDP Select runs in 90-day terms; turn off auto-renewal, let the term end, then distribute wide via Draft2Digital or direct.
Is Kindle Unlimited income really that good?
In KU-heavy genres (romance, thriller, fantasy), page-read income can beat wide sales for series fiction. In non-fiction and literary fiction, it rarely does — those readers buy outright.
What do I lose by going wide?
Kindle Unlimited page-reads and Amazon's Countdown/free-promo tools. What you gain is every other retailer, libraries, and bookshops.
