How many words are in a book? The short answer is between 60,000 and 100,000 words, but the real number depends on genre, audience and publishing platform. This 2026 guide pulls together the definitive data: tables by book type and genre, a comparison of famous English-language titles, a formula to convert words into pages, and the up-to-date minimums for Amazon KDP, Wattpad and traditional publishers.

Quick answer

An average book contains 60,000 to 100,000 words. Standard novels hover around 80,000, short stories range from 2,000 to 10,000, flash fiction stays under 500, and epic or fantasy novels can pass 150,000 words.

How many words in a book? Average, minimum, maximum

Before diving into genres and platforms, three reference points anchor everything else: the word count of an average book, the shortest publishable book and the historical ceiling. These three data points let you place your own manuscript on the right end of the scale.

Table: how many words a book has by type

The classic classification recognizes five book types based on word count. It is the first table any editor checks to see whether your manuscript fits their catalog and, in self-publishing, it determines the category your book will appear under.

Book type Words Pages approx. Example
Flash fiction < 500 1–2 "For sale: baby shoes" (Hemingway, attrib.)
Short story 500–10,000 2–35 "The Lottery" (Shirley Jackson)
Novella 20,000–50,000 70–180 "Animal Farm" (Orwell)
Novel 60,000–100,000 220–360 "To Kill a Mockingbird"
Epic novel 120,000+ 430+ "The Pillars of the Earth"

The threshold between short story and novella is fluid: some publishers accept 15,000-word texts as novellas, others require a 25,000-word minimum. If your manuscript sits right on that boundary, check the publisher's guidelines before submitting.

Words per literary genre in 2026

Beyond type, each genre has an expected length that the market has settled on. Knowing these ranges helps you calibrate the length of your book and avoid an automatic rejection for unsuitable extension.

A useful note for bilingual authors: Spanish runs roughly 15-20% longer than English for the same story. A translated novel that runs 80,000 words in English typically lands around 95,000 in Spanish. If you compare your manuscript against a translated bestseller, apply that factor.

Famous books: how many words they have

To place your manuscript in perspective, here is a curated table of the word counts of widely read English-language books. Numbers are approximate — they depend on edition and translation — but they work as comparative benchmarks.

The Pillars of the Earth
Ken Follett
460,000
Atlas Shrugged
Ayn Rand
645,000
War and Peace
Leo Tolstoy
587,000
It
Stephen King
444,000
The Lord of the Rings (trilogy)
J.R.R. Tolkien
480,000
Harry Potter and the Sorcerer's Stone
J.K. Rowling
77,000
To Kill a Mockingbird
Harper Lee
100,000
The Great Gatsby
F. Scott Fitzgerald
50,000
The Little Prince
Antoine de Saint-Exupéry
17,000

Notice the contrast: The Little Prince contains 38 times fewer words than Atlas Shrugged, and both are global bestsellers. Length does not determine commercial impact; the story and reader fit do.

From words to pages: the 2026 formula

The inevitable question: how many pages will my book be? It depends on print format, font and layout, but there is a stable formula the publishing industry has used for decades.

Formula
Pages ≈ Words ÷ 275
  • 📘 Fiction: ÷ 280 words/page
  • 📗 Non-fiction: ÷ 233 words/page
  • 📕 Academic: ÷ 350 words/page

Practical example: an 80,000-word novel runs roughly 290 pages in 5×8 inch trim with 1.5 line spacing. The same word count in mass-market paperback (4.25×6.87 in) rises to ~330 pages; in a hardcover trade size (6×9 in) it drops to 250.

Reading time and writing time by book length

Knowing how many words a book has has two practical consequences: how long the reader will spend finishing it and how long you will spend writing it. At 250 wpm reading speed and 500 words/day writing (the Stephen King classic target), the numbers look like this:

Length Reading Writing (500/day)
20,000 (long short story)1 h 20 min40 days
50,000 (novella)3 h 20 min100 days (~3 months)
80,000 (standard novel)5 h 20 min160 days (~5 months)
120,000 (epic)8 h240 days (~8 months)
200,000 (saga)13 h400 days (~13 months)

More words = better book? Myths and truths

A book's word count is just a technical number, not a quality measurement. These three myths keep circulating among new writers and deserve to be dismantled:

❌ Myth

"My book needs at least 100,000 words to be taken seriously as a novel."

✅ Reality

The Little Prince (17,000 words) has sold over 200 million copies in 80 years.

❌ Myth

"The more words a book has, the higher critics will rate it."

✅ Reality

Hemingway won the Nobel with novels of 30,000–50,000 words. Concision wins prizes too.

❌ Myth

"If I don't hit 80,000 words, no editor will read me."

✅ Reality

The word count of a book is decided by the story. Indie publishers regularly accept 40,000-word novels.
