How Long Should a Story Be?

Why does story length even matter?

People argue about this endlessly. Some swear a novel must be at least 80,000 words or it “doesn’t count.” Others boast about finishing a bestseller in 45,000. And then there are short stories so tight and powerful they hit harder than a 500-page doorstop.

Truth: your story should be as long as it needs to be. But that’s not a satisfying answer, is it? You came here for numbers. And I’m going to give you numbers. (Spoiler: a lot of famous books completely ignore the so-called rules. And yes, some are shockingly short.)

The “official” guidelines (for reference)

Agents and publishers often suggest:

Flash fiction: under 1,000 words
Short story: 1,000–7,500 words
Novelette: 7,500–20,000 words
Novella: 20,000–50,000 words
Novel: 50,000+ words

Neat in theory. But in practice, successful books ignore these boundaries all the time. Readers care about the story, not the number.

Famous books that broke the “rules”

Short novels that sold millions:

Animal Farm by George Orwell → 29,966 words. A political classic. Barely a novella by modern standards.
Of Mice and Men by John Steinbeck → 29,160 words. High school staple. Brutal, short, unforgettable.
The Great Gatsby by F. Scott Fitzgerald → 47,094 words. Taught in every literature class. Shorter than some thrillers’ first acts.

Huge novels that readers still devour:

Harry Potter and the Order of the Phoenix by J.K. Rowling → 257,154 words. Fans read it in a weekend.
The Goldfinch by Donna Tartt → 296,566 words. Won the Pulitzer Prize.
A Game of Thrones by George R.R. Martin → 292,727 words. And that’s just book one.

Modern examples that bend the rules:

The Midnight Library by Matt Haig → 67,400 words. A slim novel compared to most, yet a global bestseller.
Verity by Colleen Hoover → 99,000 words. Tense, addictive, and proof thrillers don’t need to be 500 pages.
Project Hail Mary by Andy Weir → 152,000 words. Long, but readers loved every page.

So yes, you can go short, or you can go long. Both can hit bestseller lists. Both can win prizes.

Why do writers obsess over word count?

Because it’s trackable. 500 words today, 2,000 tomorrow. It feels like progress. Word count is neat, measurable, and safe.

But here’s the twist: agents and editors who shout “70,000 minimum” aren’t the final word. They’re gatekeepers, not gods. Plenty of indie authors have ignored those limits and found huge audiences. Colleen Hoover didn’t blow up because she hit 80,000 on the dot. She did it because readers couldn’t put her books down.

Readers don’t care about 45,000 versus 145,000. They care about crying on the bus or staying up until 3 a.m. turning pages.

How to decide YOUR story length

Some genres do have expectations. Break them carefully.

Fantasy and science fiction: Readers often expect longer books. World-building takes pages. A debut fantasy novel under 70,000 words may feel rushed. But over 300,000 can test patience.

Romance: Works well at many lengths. Many romance novels sit between 50,000 and 90,000 words. Kindle Unlimited has also made shorter, bingeable romances popular.

Thrillers and crime: Fast and punchy works best. 70,000 to 100,000 is common. Shorter than that can feel undercooked. Longer than that risks dragging.

Literary fiction: Rules are flexible here. Writers can succeed with 40,000 words (The Sense of an Ending by Julian Barnes) or 400,000 (Infinite Jest).

Young Adult: 60,000 to 90,000 is standard. But plenty of short YA novels have won awards.

Step by step: How to check if your story is the right length

Finish your draft. Don’t worry about word count until you’ve written the full story.
Check pacing. Do you have saggy middle chapters? Do you rush the ending? Word count can reveal bloat or gaps.
Compare within your genre. Pick five popular books similar to yours. Look up their word counts online. Where does yours fall?
Cut or expand. If you’re 40,000 words under genre norms, consider what’s missing. If you’re 40,000 over, ask if every subplot earns its place.
Ask beta readers. Do they feel the story is too fast, too slow, or just right?
Decide based on quality, not numbers. If your novel is short but powerful, let it stand. If it’s long but gripping, keep it long.

The danger of padding

Padding your story just to hit a word count is a mistake. Readers notice filler, and they dislike it.

Filler scenes destroy tension. Extra description dilutes emotion. You don’t need 1,000 words about how your hero makes tea unless it reveals something new. (Looking at you, George R.R. Martin’s endless food scenes. Yes, we get it. The feast was big.)

Better a short, tight story than a bloated one.

The danger of cutting too much

On the other hand, trimming too aggressively can ruin a story. Readers dislike rushed endings and characters who change overnight without development.

Take Mockingjay by Suzanne Collins. Many fans felt it was too short and that the ending was rushed compared to the build-up in earlier books. A few extra chapters could have made the conclusion more satisfying.

So yes, too short can be just as damaging as too long.

Real talk: NaNoWriMo and the 50,000-word myth

National Novel Writing Month (NaNoWriMo) set 50,000 words as the target. People repeat this number like it’s sacred. But it’s arbitrary. 50,000 words gets you Of Mice and Men length, which works fine. It also gets you half a fantasy novel, which does not.

NaNo is a drafting tool, not a publishing rule. Do not query a 50,000-word epic fantasy. And don’t panic if your thriller draft comes out at 120,000. Context matters.

Common pitfalls with story length

Too long: Most beginner drafts are bloated. Think three prologues, endless world-building, or a chapter where your character dreams for twenty pages. Readers don’t care about all that. Cut it. Look at your shelf: how many bestsellers are over 200,000 words? A few. How many sit between 70,000 and 100,000? Most. Readers prefer tight, compelling stories.

Too short: Some writers brag about how brief their novels are. “I wrote a 30,000-word book and self-published it. It’s perfect.” That’s not a novel. It’s a novella. That’s fine, but be clear about it. Readers feel tricked if the packaging doesn’t match the reality.

Yes, short can work (Animal Farm proves it). But you still need depth.

Famous examples to borrow confidence from

Coraline by Neil Gaiman → 38,000 words. Slim, terrifying, unforgettable.
Ready Player One by Ernest Cline → 136,048 words. A modern pop culture giant. Long, but fun.
Gone Girl by Gillian Flynn → 145,719 words. A thriller that ignored “too long” and still dominated.
The Old Man and the Sea by Ernest Hemingway → 26,531 words. Won the Pulitzer. Proof size doesn’t matter.

Step by step: How to choose the right length for your book

Pick your genre. Fantasy usually runs longer, romance is flexible, thrillers land mid-length.
Research 5–10 popular books. Write their word counts down.
Draft your book without worrying about numbers. Focus on story first.
Check your word count afterwards. See if you’re way outside the usual range.
Adjust only if needed. Cut padding or expand rushed sections.
Trust your story. A gripping 55,000-word novel is better than a boring 95,000-word one.
