Novel Word Count: A Guide to How Long Your Book Should Be
You’re in the middle of writing your novel, and a persistent, practical question begins to loom: “How long is this supposed to be?” The novel word count is one of the first things a literary agent or an experienced reader will notice. While a story should be as long as it needs to be, your book must also fit within the established conventions and expectations of its specific genre.
Writing a book that is significantly too long or too short for its genre can be a major red flag in the publishing industry. This guide will break down the standard, commercial word count ranges for the most popular novel genres to help you set a professional and achievable target.
Key Takeaways & Summary
Genre Expectations are Key: The ideal word count for your novel is determined almost entirely by its genre.
The Sweet Spot for a Debut Novel: For most adult commercial fiction genres, a debut novel should aim for a word count between 80,000 and 100,000 words.
Word Count Signals Professionalism: Adhering to genre conventions for word count shows literary agents and readers that you understand the market.
It’s a Guideline, Not a Law: While these are the industry standards, there are always exceptions. However, for a debut author, it is a very wise to aim for the middle of the expected range.
Standard Novel Word Count by Genre
Here are the typical word count ranges for major commercial genres. These are guidelines that are widely accepted in the traditional publishing industry and are a frequent topic of discussion on agent blogs and in resources from organizations like the Alliance of Independent Authors (ALLi).
Commercial & Literary Adult Fiction
Sweet Spot: 80,000 – 100,000 words
Notes: A book under 70,000 words may be seen as too slight, while a book over 110,000 words from a debut author can be a hard sell due to higher production costs.
Romance
Sweet Spot: 70,000 – 100,000 words
Notes: Romance has many subgenres with different expectations. A shorter, contemporary category romance might be 50,000 words, while a sweeping historical or paranormal romance could be longer.
Mystery, Thriller & Suspense
Sweet Spot: 70,000 – 90,000 words
Notes: These genres are expected to be lean, fast-paced, and tightly plotted. A thriller that is too long can lose its sense of urgency and pacing.
Science Fiction & Fantasy
Sweet Spot: 100,000 – 120,000 words
Notes: Sci-fi and fantasy are the major exceptions to the “under 100k” rule. Due to the need for complex world-building, these novels are expected to be longer. However, a debut author should still be cautious about exceeding 120,000 words.
Young Adult (YA)
Sweet Spot: 60,000 – 80,000 words
Notes: YA novels are typically shorter and more tightly focused than their adult counterparts. YA fantasy can sometimes creep up to 90,000 words.
Middle Grade (MG)
Sweet Spot: 30,000 – 50,000 words
Notes: Aimed at readers aged 8-12, these stories are significantly shorter.
Why Does Word Count Matter So Much?
For Traditional Publishing: A literary agent uses word count as a first-pass filter. A manuscript with a wildly inappropriate word count signals that the author may not be familiar with the professional standards of their genre. It also has a direct impact on the physical cost of printing a book.
For Independent Publishing: While you have more freedom, reader expectations are still a powerful force. If a romance reader is expecting an 80,000-word story and your book is only 30,000 words, they may feel short-changed and leave a negative review.
For the Story Itself: These word count ranges exist for a reason. They are the length that is generally required to tell a complete, satisfying story within that genre’s structural conventions.
If you find your story is much longer or shorter than your genre’s target, it may be a sign of a structural issue that needs to be addressed during the revision process. Our book editing services can provide invaluable feedback on this.
Short FAQ
Q: What is the absolute minimum word count for a novel?
A: A work of fiction is generally considered a “novel” if it is over 40,000 words. Anything shorter is a “novella.”
Q: My first draft is only 50,000 words, but I’m writing a fantasy. What do I do?
A: This is very common. A first draft is often the “skeleton” of the story. During the revision process, you will likely be adding subplots, deepening character motivations, and fleshing out your descriptions, which will naturally increase your word count.
Q: Are there famous exceptions to these rules?
A: Yes, many. Harry Potter and the Sorcerer’s Stone is about 77,000 words. The Lord of the Rings is a massive epic. However, it is a very risky strategy for a debut author to try to break these conventions. The best strategy is to prove you can master the standard form first.
