When talking about your writing project with a friend, one of their first questions will likely be “What is the genre?” To them, it may seem like a simple question. To you, it may feel impossible to categorize your writing into any one rigid genre.
Choosing a genre plays into every part of the publishing end of your projects. Genre informs the design for your book covers, marketing, and finding the right readers to increase your book sales. In this article, I’ll define genre, look at the main novel genre forms, and offer you a Story Weapon to unlock the story within you.
A book’s genre categorizes it by form, style, and subject matter, helping readers know what to expect and guiding publishing decisions like marketing and cover design. While there are many genres and subgenres, nine main novel categories capture the broadest types of stories.
What is genre?
A genre is a category characterized by similarities in form, subject matter, and style found in any artistic composition.
It is essentially a group that a body of work falls within due to the content and how it is written. The genre tells the readers what kind of content they can expect.
The exact number of genres that exist, depends on who you ask. Most will claim there are around 50 genres of books. Most genres can be broken down into two main categories: Fiction or Nonfiction.
Subgenres
If we keep going down this rabbit hole, we will find books that combine genres such as Fantasy and Romance creating its own book baby we call subgenres.
Subgenres are used when a book can fall under more than one genre or contains elements of multiple different kinds of genres.
Because there are seemingly endless genres and subgenres in the book world, in this article we are going to focus on the various genres of fiction novels.

What are the 9 main genre categories in fiction?
A fictional novel is a work generally containing 40,000 – 100,000 words. When we look into the genres that exist within fiction, we can pinpoint 9 main categories.
There is debate on the exact number as, for example, some consider dystopian books to be their own genre while many agree they are just a subgenre of fantasy or sci-fi novels.
Or some argue Young Adult is its own category, while others say it is just an age restriction on all the other genres.
In order to not anger the genre gods, we are going to focus on the top 9 genres that are universally agreed on: Fantasy, Romance, Sci-Fi, Thriller, Horror, Mystery, Adventure, Historical, Literature.

Your story weapon: Keep your head out of the result
When push comes to shove, you may need to pick a genre to sell your book under, but don’t let this limit your writing. While genre can inform the style of your writing, the story you need to tell is already inside of you. You just need to let it out.
Don’t get distracted by dollar signs. If you set out to write a bestseller, chances are you won’t end up writing the story you were meant to tell. You put a cap on your subconscious, taking control of what you allow out.
If you are looking into self-publishing, you may have noticed that Amazon offers over 10,000 categories to choose from. That is an overwhelming number! However, this does not mean you have to limit your writing to fit between the lines of a predetermined category. There are over 10,000 options on Amazon because new work is breaking boundaries all the time.
