📚 How to choose a genre for your book

Choosing a genre is your first business decision as an author, not just a creative whim: it determines who will read your book, which store shelf it lands on, and which algorithm picks it up. And the market right now rewards those who hit the right niche more than ever. According to Circana BookScan data published by Publishers Weekly in January 2026, 762.4 million print books were sold in the US in 2025. These are record numbers, but growth was distributed very unevenly across genres. This article will help you choose a direction deliberately, based on your strengths and real data rather than guesswork. For beginning authors: publish your work on this marketplace and get feedback.

💡 Quick overview: to choose a genre that won't disappoint either you or the reader, work through four steps in order, moving from yourself to the market, not the other way around.

  • Step 1. Define your authorial voice: what you read obsessively and what you can write about for months without burning out.
  • Step 2. Check your interests against 2025-2026 sales data and trends.
  • Step 3. Study the conventions of your chosen genre, meaning the reader expectations you cannot break.
  • Step 4. Test your hypothesis with short pieces before investing a year in a novel.

The most common beginner mistake is choosing a genre "because it sells" and abandoning the manuscript halfway through because writing in it turned out to be agonizing. The genre you write in should match the genre you love to read. This isn't sentimentality: if you've read a hundred detective novels, you intuitively sense where to hide a clue and when to give the reader a breather. If you take on fantasy without ever reading a saga, the reader will feel the falseness in the first chapter.

To find your direction, answer three questions honestly. Which books dominate your shelf? What can you talk about for hours with friends? Which scenes come to you most easily: chases, emotional dialogue, world descriptions? The answers form a map of your strengths. Work experience, hobbies, and personal stories also point to a theme: a former lawyer will write a believable legal thriller, and someone who has lived through loss will create a piercing drama.

📊 Check the market: which genres are growing in 2025-2026

Love for a genre is the foundation, but without understanding the market you're building a house in the desert. The latest data shows that audiences vote with their wallets very selectively. According to the Circana BookScan report, sales in the "romance" category grew 3.9% in 2025 to nearly 44 million copies, while fantasy sales fell 8.7% to 24.1 million. That's an important signal: even "evergreen" genres go through ups and downs depending on viral cycles and screen adaptations.

Social media has become the main driver of demand today. According to TikTok Newsroom data for 2025, the #BookTok community helped sell more than 50 million books across Europe worth about 800 million euros, and more than a third of readers aged 16-39 discover new books there. In Germany, sales of books recommended on TikTok grew from 12 million in 2023 to 28 million in 2025, more than doubling in two years.

Worth highlighting separately is "romantasy" (romantasy), a hybrid of romance and fantasy. Its sales grew to 610 million dollars in 2024, up from 454 million the year before, according to industry estimates. It is now the fastest-growing market segment, and its rise shows that blending genres carries opportunity, not risk.

Stacks of books of different genres on a shelf

🌌 Understand genre conventions before breaking them

Every genre has an unspoken contract with the reader. A mystery fan expects the crime to be solved and the clues to be shown fairly. A romance reader expects a happy or at least hopeful ending, and if you break that, you'll get a wave of angry reviews. A fantasy fan forgives a slow start for the sake of a well-developed world, while a thriller reader will drop the book if nothing happens in the first chapters.

Understanding these conventions gives you a tool, not a cage. Knowing the rules, you decide consciously which ones to follow and which to subvert unexpectedly. Before writing, take apart three or four bestsellers in your chosen genre the way a mechanic takes apart an engine: where the main conflict appears, how many plotlines there are, what the pacing is, how the resolution works. That gives you the framework of reader expectations that any successful book rests on.

🎨 Blend genres deliberately

Don't be afraid to experiment, but do it with understanding. The success of romantasy proves that skillful genre blending doubles your audience: you attract both romance fans and fantasy lovers. A romantic mystery, a science fiction drama, a historical thriller all bring freshness and make a book stand out on a crowded shelf.

But blending has a rule: one genre must lead, and the second is seasoning. If you try to please everyone at once, you'll please no one, and store algorithms won't know which shelf to put you on. Decide what matters most to you, the emotional arc of a relationship or an adventure in a magical world, and build the second layer around that core.

🧠 Know your audience

Choosing a genre is inseparable from choosing a reader. Younger audiences gravitate toward young adult, dystopias, and romantasy; mature readers prefer historical novels, family sagas, and psychological thrillers. And here again, audience behavior online is decisive.

According to Pew Research Center research conducted in October 2025, 75% of American adults read at least one book in the past year, with print remaining the most popular format. That means the physical book and its cover still matter, and collector's editions are especially valued by young romantasy fans. By understanding where your reader lives and what they buy, you're choosing not just a genre but the channel through which the book will reach them.

🌟 Learn from a real case: the "Onyx Storm" phenomenon

A good example of how the alignment of genre, audience, and timing creates a breakthrough came from Rebecca Yarros's novel "Onyx Storm." This romantasy book launched at the peak of interest in the category and, according to BookScan data reported by industry press, sold more than 1 million copies in its first week. That was the fastest start for an adult book in BookScan's entire tracking history.

Why did it work? The author wrote in a genre she loves and understands; she hit the BookTok audience precisely, an audience ready to share the book; and the genre itself was on a rising wave. The takeaway for a beginning author is simple: breakthroughs don't happen by chance, they happen at the intersection of three axes, your passion, real market data, and understanding where the reader is. No single axis can carry a book on its own.

🖋️ Test your hypothesis before investing a year

Before devoting twelve months to a novel, test the direction at low cost. Write a few short stories in different genres. This will show you which one you write in more easily and with more interest, and ease of writing is often the sign of your true genre.

Post these pieces where there's a live audience and gather feedback. Reader reactions will tell you more than any theory: where they laughed, where they got bored, where they couldn't put it down. This approach saves months and protects you from the biggest risk, spending a year of work on a book in a genre that turns out to be alien to you.

⁉️🤔 Common questions about choosing a genre

Do I need to choose a genre before starting work on a book?

Preferably, but not rigidly. Knowing the genre sets the structure, pacing, and reader expectations at the planning stage, which saves time on rewriting. That said, many authors only understand their genre in the process. If that's you, don't blame yourself, and settle on it after the first draft, guided by what came most naturally.

Should I write in a popular genre just for sales?

No, if you don't love it. According to Circana BookScan, romance sales grew 3.9% in 2025 while fantasy fell 8.7%, and trends shift within a season. A book takes a year or more to write, and fashion can turn in that time. It's far more reliable to write in a genre you understand and can sustain over the long haul.

What is romantasy and why is everyone talking about it?

Romantasy is a hybrid of romance and fantasy. According to industry estimates, its sales grew from 454 million dollars in 2023 to 610 million in 2024. The genre took off thanks to the BookTok community and combines emotional relationship arcs with well-developed magical worlds, which is what attracts a young audience.

Can I blend two genres in one book?

Yes, and it's often a winning strategy. The success of romantasy proves that blending expands the audience. The main rule: one genre leads, and the second complements it. If both fight for dominance, the reader and store algorithms won't understand what to expect from the book.

How do I know I've chosen the right genre?

A reliable sign: ease and enjoyment while writing. Write a few short stories in different directions and compare where the text flowed on its own and where you had to force your way through. Also gather feedback from readers, since their reaction will confirm or refute your hypothesis faster than a whole novel.

📚 In conclusion

Choosing a genre lies at the intersection of three lines: what you love to write, what the market buys, and where your reader is. Start with yourself, check the 2025-2026 data, study the conventions, and test your hypothesis with short pieces. Don't be afraid to blend genres, but keep one of them leading. Trends will change, romance is growing, fantasy is dipping, romantasy is soaring, but your genuine interest in the subject will remain the main fuel that carries the book to the finish.
