How Many Words Should a Novel Be?

There is no single correct novel length — the commonly cited ranges vary by genre, from roughly 40,000 words for some middle-grade fiction to 110,000+ for epic fantasy — so the useful question is not “how long should a novel be” but “how long is typical for the genre I’m writing.” These are widely published conventions used by literary agents and publishers as general guidance, not hard rules — a manuscript outside the range is not automatically rejected, but it does need a stronger reason to be that length than “that’s how long the story turned out to be.”

The reason genre matters so much here is that word count functions partly as a signal to agents and readers about pacing and scope before anyone opens the book — a 130,000-word romance and a 130,000-word literary novel are reading very different signals about what’s inside, even at the identical length.

Commonly cited ranges by genre

These are ranges, not thresholds — a manuscript at 68,000 words in a genre with a 70,000-word floor is not disqualified, and one at 125,000 in a genre with a 120,000-word ceiling is not automatically too long. They function as a planning target during drafting and outlining, and as one data point (among many) once a manuscript goes out to agents.

Where the 50,000-word number comes from

NaNoWriMo (National Novel Writing Month) sets its annual goal at 50,000 words, which has made that number widely recognized as “a novel” in casual conversation — but 50,000 sits at or below the floor for most adult fiction genres. It’s a real, useful drafting target for the reason it was designed: a complete, if short, draft in 30 days. It is not, on its own, evidence that 50,000 words is a publishable adult novel length — treat it as a drafting milestone, and expect most manuscripts, especially genre fiction, to grow past it in revision.

Using a target during outlining

A word-count target is most useful as a proportion, not a fixed number. Standard three-act structure allocates roughly:

Outlining against proportions instead of a hard total means the plan survives a genre change or a target that shifts once the draft is underway — the beats scale with the book rather than needing to be re-planned from scratch.

Debut vs established-author expectations

Ranges published for “the genre” are often really ranges for a first-time author in that genre — an established author with a readership can and does publish well outside them. A debut fantasy manuscript at 160,000 words faces a harder path to a first book deal than the same manuscript from an author with three prior published novels, not because the writing changed, but because a publisher is taking less risk on a known audience regardless of length. New writers benefit from treating the lower half of a genre’s typical range as the safer target, and saving a longer, more ambitious book for once a readership exists to support it.

Common questions

Is a first draft allowed to be shorter or longer than the target? Yes, and it usually is — a first draft commonly runs 10-20% off the eventual target in either direction, and revision is where length gets pulled back toward the genre’s typical range, not the outline stage.

Does a shorter novel mean less work? Not necessarily — a tightly plotted 70,000-word thriller can take as long to draft and revise as a sprawling 120,000-word fantasy, because the effort is in structure and pacing, not raw word count.

What if my genre isn’t in the table? Look at recently published, comparable titles in your specific subgenre rather than a general category — published comp titles are a more current and specific signal than any general range, including this one.
