Most adult novels land between 70,000 and 100,000 words, which is roughly 250 to 400 printed pages. That is the short answer. The longer answer is that every genre has its own expected range, and readers, agents and stores all notice when a book sits far outside it.
The quick version:
- Average novel: 70,000 to 100,000 words.
- Shortest length most people still call a novel: around 40,000 to 50,000 words.
- Novella: 20,000 to 50,000 words.
- Young adult: 55,000 to 80,000 words. Middle grade: 25,000 to 50,000.
- Picture book: under 1,000 words across 32 pages.
- Non-fiction: 40,000 to 60,000 for business and self-help, 60,000 to 90,000 for memoir.
Word count is not an artistic rule. It is a reader expectation baked in by decades of shelf habit. A 40,000-word epic fantasy feels thin. A 200,000-word debut romance does not get read. Hitting the range is the cheapest credibility you can buy.
Word count by genre
These are the ranges commonly cited by agents, publishers and writing guides. Treat them as typical ranges rather than hard limits. The page column assumes a standard 6x9 paperback at 250 to 300 words per page.
| Genre or format | Typical word count | Approx. printed pages |
|---|---|---|
| Flash fiction | Under 1,000 | 1 to 4 |
| Short story | 1,000 to 7,500 | 4 to 30 |
| Novelette | 7,500 to 20,000 | 25 to 80 |
| Novella | 20,000 to 50,000 | 70 to 200 |
| Romance | 50,000 to 90,000 | 170 to 360 |
| Mystery and thriller | 70,000 to 90,000 | 230 to 360 |
| Literary and commercial fiction | 70,000 to 100,000 | 230 to 400 |
| Historical fiction | 90,000 to 120,000 | 300 to 480 |
| Science fiction and fantasy | 90,000 to 120,000 | 300 to 480 |
| Epic fantasy | 120,000 to 180,000 | 400 to 720 |
| Young adult (13+) | 55,000 to 80,000 | 180 to 320 |
| Middle grade (8 to 12) | 25,000 to 50,000 | 85 to 200 |
| Chapter book (6 to 9) | 5,000 to 12,000 | 50 to 100, illustrated |
| Early reader (5 to 7) | 1,500 to 3,000 | 32 to 64, illustrated |
| Picture book (3 to 8) | 500 to 1,000 | 32, illustrated |
| How-to and practical guides | 30,000 to 50,000 | 100 to 200 |
| Business and self-help | 40,000 to 60,000 | 130 to 240 |
| Memoir | 60,000 to 90,000 | 200 to 360 |
| Narrative non-fiction | 70,000 to 100,000 | 230 to 400 |
| Academic and reference | 80,000+ | 270+ |
Books for younger readers use bigger type and more white space, so their page counts run higher than the 250 to 300 rule suggests. Picture books are the exception to everything: the page count is fixed by the format and the words have to fit it.
What is the average novel word count?
Around 80,000 to 90,000 words is the middle of the market for adult fiction, and 70,000 to 100,000 covers most novels you will find on a shelf. Genre moves this a lot. Romance and thrillers sit at the lower end, while fantasy, science fiction and historical fiction run longer because the world takes words to build.
If you are writing a first novel and you are not sure where to aim, 80,000 words is a safe target for almost any adult genre.
How many words are in a novel, at minimum?
There is no single official cutoff, but most people stop calling a book a novel somewhere around 40,000 to 50,000 words. Below that it is usually treated as a novella. In practice, an adult novel under 60,000 words will read as short to agents and many readers, even if it technically qualifies.
What is a novella word count?
A novella is typically 20,000 to 50,000 words, roughly 70 to 200 printed pages. It is long enough for a full arc and a real character change, and short enough to read in an evening or two. Below about 20,000 words it becomes a novelette, and below 7,500 a short story.
Novellas are hard to sell to traditional publishers as standalone debuts, but they work well in self-publishing, especially as series starters, reader magnets and in-between installments.
How many pages is 50,000 words?
About 170 to 200 pages in a typical 6x9 paperback, at 250 to 300 words per page. In standard manuscript format (12-point font, double-spaced) it is roughly 200 pages. Single-spaced in a word processor, it is closer to 100.
The same maths for other common lengths:
- 50,000 words is roughly 180 printed pages
- 80,000 words is roughly 290 printed pages
- 100,000 words is roughly 360 printed pages
- 120,000 words is roughly 430 printed pages
Trim size, font size and leading all move this, so treat it as an estimate until you export a real interior. Page count matters for print because it sets your spine width, and the spine has to be exact before you build a wraparound cover. Print-ready interiors covers the specifics.
How long should a fantasy or sci-fi novel be?
Adult fantasy and science fiction usually run 90,000 to 120,000 words, and epic fantasy goes well past that. Two notes on the fantasy numbers. A debut at 180,000 words is a hard sell even inside epic fantasy, so first-timers are safer near 110,000. And self-publishing loosens all of this: nobody rejects your manuscript, but print costs rise with page count and long books get more refunds if the pacing sags.
How long should a children's or YA book be?
Young adult runs 55,000 to 80,000 words and middle grade 25,000 to 50,000. Books for younger children are measured in hundreds or low thousands of words.
Picture books are the strictest category on this page. A 32-page picture book with 2,000 words of text will not fit the spreads, and it is the single most common reason a first children's book manuscript gets sent back. Aim under 1,000 and read it aloud with a timer.
How long should a non-fiction book be?
Most non-fiction lands between 40,000 and 70,000 words, and it rewards being shorter than you think. A tight 45,000-word book that solves one problem outsells a 90,000-word book that covers a field, because readers buy the promise on the cover and finish books they can finish. Memoir and narrative non-fiction run longer, closer to novel length, because they are telling a story.
How to hit your target without padding
Set the scale before you draft, not after. In Advanced Mode on the create screen you set the chapter count (up to 32) and pages per chapter (up to 10) up front, so the outline is built to a length instead of being stretched or hacked down later. Short stories cap at 10 chapters, which is the right instinct for the format.
Structure, then wordage. If a book is running short, the fix is almost never longer sentences. It is a missing subplot, an underused secondary character, or a middle act with one obstacle where it needs three. If it is running long, the fix is usually two characters who do the same job.
Count as you go. The editor tracks word count while you write, so you can see a chapter that is 900 words when the rest are 2,500 and ask why.
Cut in a second pass, not the first. Draft to the top of your range and trim by 10%. Everyone's first draft has a percentage of throat-clearing in it, and it is easier to find once the whole shape exists.
When to ignore all of this
If you are self-publishing and you have an audience that wants exactly what you make, the ranges are guidance and nothing more. Serialized fiction, webtoons and short-read markets all run on completely different math. Webtoons are measured in episodes and panels, not words at all.
The ranges matter most when you are asking a stranger to take a chance on you: an agent, a publisher, or a reader browsing a store page. Land inside the range and let the book be the thing that stands out.
