How Many Words Should a Novel Have? The Guide by Genre

Nearly every first time novelist asks the same question: how many words does it take to actually call a manuscript a novel, and how many is too many for the genre they picked. The answer shifts a lot by category. A thriller and an epic fantasy do not answer to the same standards, and missing the range can make a manuscript harder to place with agents and publishers.

Key Takeaways

• A standard novel runs 70,000 to 100,000 words (Reedsy, 2026).

• Fantasy and sci-fi are the longest genres: 100,000, 115,000 words (Reedsy, 2026).

• Young adult stays more contained: 55,000, 80,000 words (Writer's Digest).

• Under 40,000 words, it's a novella, not a novel.

• Publishers also weigh internal consistency: a 120,000 word thriller slows the pacing the genre promises.

How Many Words Does the Average Novel Have?

On average, an adult novel sits between 70,000 and 100,000 words (Reedsy, How Many Words in a Novel?, 2026). That range covers most published general fiction and literary fiction, and it's the benchmark literary agents and editors keep in mind when a debut manuscript lands on their desk.

Staying in this range isn't an aesthetic constraint. It's about print costs, reader expectations, and how a book sits on the shelf next to comparable titles: even a novel now considered a classic, The Great Gatsby, left its author anxious that it was too short to be taken seriously (Jane Friedman, Obsessing Over Your Manuscript's Size, 2026). A debut author submitting 180,000 words without a genre that justifies it, epic fantasy, sweeping historical fiction, risks rejection before the editor even reaches page one.

How Long Should a Fantasy Novel Be?

Fantasy and sci-fi for adults are the genres with the widest range: 100,000, 115,000 words, with several published series running past this threshold (Reedsy, How Many Words in a Novel?, 2026). Worldbuilding, magic systems, and ensemble casts demand room that other genres don't allow.

YA fantasy, by contrast, sits closer to standard YA territory: 55,000, 80,000 words. The difference isn't just the reader's age, it's pacing: a YA fantasy keeps a tighter plotline, while epic fantasy for adults stretches subplots across multiple books.

Anyone writing a saga should still judge each volume as a standalone unit. An editor evaluates the first book even when the plan is to write five.

How Many Words Does a Romance Novel Have?

Commercial romance sits between 80,000 and 100,000 words (Reedsy, How Many Words in a Novel?, 2026). Shorter category romance lines tend toward the lower end of this range, while ensemble or cross-genre romance can approach the upper limit.

That rigidity comes from the market itself: romance imprints publish high, predictable volumes, and a significant deviation from the standard format complicates fitting into a line. Self-published authors have more freedom, but genre readers are still used to a precise reading rhythm.

It's worth noting romance is also the genre where perceived length matters more than exact count: a well paced 80,000 word romance reads "fuller" than a thriller of the same length with bloated chapters.

How Many Words Should a Young Adult Novel Have?

A typical young adult novel runs 55,000 to 80,000 words (Writer's Digest, Word Count for Novels and Children's Books). The genre rewards pacing and narrative voice over plot complexity, so agents and editors grow wary of YA manuscripts past 100,000 words without a genre justification (fantasy or ensemble dystopian).

Middle grade, the bracket right below YA, drops even further: 20,000, 55,000 words (Writer's Digest, Word Count for Novels and Children's Books). Knowing this distinction avoids writing a book that ends up squeezed between two categories, without a clear editorial home.

How Many Words Should a Thriller or Mystery Have?

Commercial thrillers and mysteries sit between 80,000 and 100,000 words (Reedsy, How Many Words in a Novel?, 2026). The tight pacing the genre promises readers gets hard to sustain past that threshold: an overly long thriller tends to lose the tension that defines it. In both cases, the unwritten rule is that every scene must earn its place against the overall pacing, or the word count becomes a structural problem, not just an editorial one.

How Many Words Does a Literary Novel Have?

Literary fiction generally sits between 80,000 and 100,000 words, with notable exceptions in both directions (Reedsy, How Many Words in a Novel?, 2026). Here, word count matters less than in other genres, because a text's perceived value comes from voice and construction, not from meeting a market standard.

That said, a literary debut under 60,000 words risks being classified as a novella by publishers, while going substantially past the upper limit without a structure that justifies it (historical epic, multigenerational saga) makes a first submission harder.

What Happens if a Novel Is Too Short or Too Long?

Under 40,000 words, a manuscript falls into the novella category, not novel, a distinction that matters for imprints and literary prizes (Reedsy, How Many Words in a Novel?, 2026). It isn't a quality judgment, but a classification that determines where and how the book can be pitched.

Above a genre's maximum threshold, the main risk isn't automatic rejection, but higher editing and printing costs, along with a reading pace that can feel diluted. Many editors recommend cutting before submission, rather than hoping the editor will cut it for you.

Frequently Asked Questions

Is a 50,000 word novel too short?

It depends on the genre: for contained YA or middle grade, 50,000 words can fit the standard. For romance, general fiction, or thrillers, it's below the typical commercial range, and several publishers classify it as a short novella (Reedsy, 2026).

What's the average word count for a published novel?

The overall average for adult fiction sits around 80,000, 90,000 words (Reedsy, How Many Words in a Novel?, 2026), but it varies noticeably depending on the specific genre a manuscript belongs to.

Does word count include dialogue and descriptions?

Yes, standard word count includes every word in the text, dialogue included. There's no separate count for narration versus dialogue under current publishing standards.

Can I go over my genre's range if the story needs it?

It's possible, but it raises the bar for landing an agent as a debut author. Already published authors have more leeway, since editors and readers already have an established trust relationship with their writing.

How many words does the average novelist write per day?

NaNoWriMo's standard daily target is 1,667 words a day, the pace that gets a writer to 50,000 words in a month of continuous writing (Freewrite, How Many Words for NaNoWriMo?, 2026). At the same pace, a standard 80,000, 90,000 word novel gets finished in about two months of daily writing.

In Summary

The right word count for a novel depends on genre before it depends on story. Epic fantasy and a young adult novel answer to opposite standards, and knowing them before writing avoids having to cut, or stretch, a manuscript that's already finished. The most useful rule stays simple: write the story that the book needs, then check the result against your genre's standard, not the other way around.
