You’ve got a book idea rattling around in your brain. Maybe you’ve even started writing. But before you dive too deep, let’s pause and ask the million-dollar question: what genre of books sell the most?
Whether you’re a seasoned writer or working with an ebook writer for hire, understanding your genre isn’t just helpful; it can be the difference between a bestseller and a book that gathers dust on digital shelves. Let’s break it down and give you a data-backed look at what’s hot in 2025 and how to align your writing with reader demand.
First, What Even Is a Genre?
In case you’re wondering, genre isn’t just a publishing buzzword. It’s what helps readers find books they’ll actually enjoy. Romance lovers want the heart flutters. Crime readers want a juicy mystery to sink their teeth into.
And yes, you can blend genres, mixing romance with suspense, or fantasy with humor, but there’s always one dominant flavor that leads the way.
Knowing your genre helps with everything from structure to style to how you market your book later on.
What Genre of Books Sell the Most?
Let’s get to the good stuff. These are the genres that have consistently topped sales charts, whether you’re publishing traditionally or going the indie route.
1. Romance (Still the Undisputed Champ)
Romance continues to dominate both print and digital book sales. The emotional payoff, feel-good endings, and sheer volume of subgenres (contemporary, historical, paranormal, etc.) make it a reader favorite.
Especially in the eBook world, romance rules. Readers devour these books, sometimes multiple in a week, which keeps demand sky-high.
2. Crime and Thriller
Hot on romance’s heels is the ever-addictive crime/thriller genre. Think page-turners with high stakes, shocking twists, and a killer reveal (sometimes literally).
This genre keeps readers up at night and is a go-to for people who want suspense, drama, and action all rolled into one.
3. Religious and Self-Help
Self-help books rooted in personal growth, mindset, or spiritual principles are a growing force, especially in nonfiction. Religious books also hold strong, particularly when they offer comfort, insight, or tools for everyday life.
Writing in this genre? Make sure you know who you’re talking to because audience targeting is everything here.
4. Children’s Books with Humor
Books for kids (especially ages 8–12) are booming. Why? Kids still read for fun and funny sales. Parents love humor because it keeps their little ones engaged, and teachers appreciate books that are both entertaining and educational.
If you’re writing for younger readers, sprinkle in some silliness. Laughter is the fastest way to a child’s heart (and a parent’s shopping cart).
5. Fantasy & Sci-Fi (Especially for Young Adults)
Fantasy and science fiction readers are incredibly loyal. And in the young adult (YA) space, these genres absolutely thrive.
From alternate worlds to dystopian futures, the demand for escapist fiction remains strong, especially if your characters are fighting injustice, taming dragons, or falling in love across dimensions.
Need a confidence boost? Around 48% of fantasy/sci-fi sales now come from indie and self-published authors. So yes, there’s room for you too.
How Have Genre Trends Changed Recently?
In the last few years, we’ve seen genre blending rise (hello, romantic thrillers and cozy fantasy). Reader tastes are also shifting toward:
- Speculative fiction
- Diverse protagonists and voices
- Realistic, emotionally grounded storytelling in fantastical settings
Nonfiction is expanding, too. From true crime to mental health, there’s space for fresh perspectives across categories.
Ending Note
So, back to our original question: what genre of books sell the most? Romance leads the pack, with crime/thriller, self-help, children’s, and fantasy right behind.
But don’t write for trends alone. Write the story you want to tell in the genre that feels natural to you. The best books don’t just follow the market; they connect with it.

Frequently Asked Questions
Your title, subtitle (if you have one), author name, copyright info, and possibly a quote or tagline. Keep it clean, professional, and easy to read. First impressions matter, even in digital format.
That depends on your topic and audience. A standard eBook ranges from 20 to 100 pages. Fiction tends to run longer (up to 200 pages), while short nonfiction guides might land closer to 30.
Mostly through royalties. On Amazon KDP, for example, authors can earn 35% to 70% royalties depending on pricing and region. Whether you’re self-publishing or going through eBook writing services in Houston, you want to understand your royalty structure before you hit “publish.”
Technically, there’s no rule, but readers expect substance. Aim for at least 5,000 words to give your content some weight. Full-length novels usually range from 50,000 to 90,000 words.
