Every great book starts with an idea. But before you turn that idea into a manuscript, you need to answer one important question: Is your book fiction or nonfiction?
The decision to decide in which category your book fall shapes the entire book writing process. It affects how you develop your story, research your content, connect with readers, and present your work to publishers.
The difference between fiction and nonfiction may seem simple at first. Fiction comes from imagination, while nonfiction is based on real information and experiences. But many books do not fit into a perfect box. A novel can be inspired by true events. A memoir can read like a powerful story. A nonfiction book can use storytelling techniques to keep readers engaged.
At Digital Scribblers, we have helped authors understand the differences between nonfiction and fiction and choose the right direction for their books. The right category not only defines your book, but it helps you create a stronger writing strategy from the beginning.
In this guide, we will explain the key differences between fiction and nonfiction, explore popular genres under each category, and help you decide which path fits your book idea best.
Not every book fits neatly into one category. Historical fiction, creative nonfiction, and narrative nonfiction often combine factual elements with storytelling techniques. We’ll explore those later in this guide.

Fiction is storytelling born from imagination. You invent the characters, plot, and world. They exist only in your mind (and eventually, in your reader’s).
That doesn’t mean fiction is false or unimportant. Fiction explores emotional truth, psychological complexity, and human experience in ways that feel deeply real. A well-written novel can reveal more about what it means to be human than many factual accounts.
Fiction gives you creative freedom. Need a character to make a certain choice? Go for it. Want to bend the laws of physics? You can. The only rule is internal consistency. Your story must feel real within its own world.
Fiction includes: Mystery, romance, fantasy, science fiction, thriller, historical fiction, literary fiction, and countless hybrid genres
Nonfiction is the opposite. You’re telling stories that actually happened. Your characters are real people. Your events are documented. Your facts must be verifiable.
This doesn’t mean nonfiction is dry or boring. A compelling memoir or narrative history can grip readers as tightly as any novel. The difference is accountability. Readers expect truth from you, and they hold nonfiction to a higher standard than fiction.
If a fiction book contains inaccuracies, readers forgive it. They knew it was made up. But if a nonfiction book claims something false, it damages your credibility. Sometimes irreparably.
Nonfiction includes: Memoir, biography, autobiography, essay, history, self-help, narrative journalism, and any work grounded in real events and verifiable facts.

Fiction includes dozens of genres, each offering a different reading experience. While they all rely on imagination, the themes, settings, and storytelling styles vary widely.
| Genre | Description |
|---|---|

|

|
Thriller |

|

|
Historical Fiction |

|
Literary Fiction |

Nonfiction is just as diverse as fiction. Instead of imaginary stories, these books focus on real experiences, factual information, or practical knowledge. Each type serves a different purpose, from educating readers to sharing personal journeys.
Here are some of the most common types of nonfiction:
| Genre | Description |
|---|---|
|
Biography |
The story of another person’s life, based on research, interviews, and documented facts. |
|
Memoir |
A personal account that explores a specific period, experience, or theme from the author’s life. |
|
Autobiography |
The author’s life story, usually covering their life from childhood to the present. |
|
Self-Help |
Offers practical advice, strategies, or guidance to help readers improve an area of their lives. |
|
History |
Examines real historical events, people, and civilizations using factual evidence. |
|
Narrative Nonfiction |
Combines factual reporting with storytelling techniques to create an engaging reading experience. |
Every type of nonfiction has the same foundation: it is rooted in truth. The difference lies in how that truth is presented.
Fiction comes from imagination. Nonfiction is rooted in facts and real events. Fiction entertains; nonfiction informs.
Yes. Many novels are inspired by real events. What matters is that you’ve fictionalized it—invented characters, altered details, or reimagined what happened.
Sometimes, if reconstructed reasonably from available records. But you can’t fabricate entire scenes. Nonfiction demands that you stay true to what actually occurred.
It’s nonfiction. Capote meticulously researched a real crime. He wrote it with literary techniques that made it read like a novel, but the events and people are real.
Nonfiction written with the narrative techniques and emotional depth of fiction. Real stories told beautifully, with pacing, voice, and structure that rival novels.
Publishers, booksellers, and readers treat fiction and nonfiction differently. How your book is labeled affects where it’s shelved, how it’s marketed, and what readers expect from it. Choose the label that matches your book’s relationship to truth.
Choose fiction if you want creative freedom. You can invent characters, reshape events, and explore “what if” scenarios. Fiction lets you capture emotional and psychological truths without the burden of literal accuracy.
Choose nonfiction if you have a true story worth telling. A personal experience. Expertise to share. A moment in history that deserves to be documented. Nonfiction gives you authority and builds trust with readers who value authenticity.
Many successful authors write both. They might publish a thriller under their name and a memoir under it. The genres serve different purposes. Neither is easier or more valuable than the other. They’re just different tools.
What matters is choosing the one that serves your message and respects your readers’ expectations.
