What Is the Average Amount of Words in a Book? A Genre-by-Genre Guide (2026)
What Is the Average Word Count of a Book?
The average amount of words in a book is 70,000 to 100,000 words for most adult fiction and nonfiction genres. That's the baseline range that literary agents, traditional publishers, and production teams treat as standard when evaluating a manuscript's market fit.
To put that in physical terms: an 80,000-word manuscript typically produces a finished print book of approximately 250–300 pages at standard trade trim sizes, though the exact page count depends on font size, leading, and typesetting decisions. Word count isn't a stylistic preference, it's an industry signal that tells everyone from agents to printers where your book belongs in the market.
It's important to be precise about what "word count" actually means. A book's word count is the total number of words in the main text of a manuscript, excluding front matter (title page, copyright, dedication), back matter (acknowledgements, bibliography, author bio), and index unless otherwise specified. When agents ask for your word count in a query letter, they want the body count only.
Books outside the expected range for their genre face real consequences. Manuscripts that run significantly short or long face higher rejection rates from agents and higher per-unit production costs in print, according to research compiled by Reedsy and Jerry Jenkins. The word "average" can mislead authors here, because the correct benchmark is always genre-specific. A romance novel, a business book, and a middle-grade novel don't share the same professional standard, as Career Authors notes in their breakdown of genre expectations. Understanding where your book sits is a foundational step whether you're pursuing traditional or self-publishing, and it reflects how the publishing industry categorises manuscripts at every level.
Average Word Counts by Genre: The Numbers Every Author Needs to Know
Genre is the single most reliable frame for setting a word count target. Here's how the major categories break down in 2026.

Fiction Genres
Literary fiction typically runs 80,000–110,000 words. Debut manuscripts pushing past 100,000 words face steeper agent resistance, partly because of the typesetting and print production cost implications of a longer book. Reedsy's word count guide places the sweet spot for debut literary fiction firmly below that ceiling.
Commercial and upmarket romance averages 70,000–100,000 words. Category romance (shorter, series-style books) often lands in the 50,000–70,000 word range. The genre is relatively tolerant of variation within those bands, but submissions outside them draw scrutiny.
Thrillers and crime fiction target 80,000–100,000 words. The pacing demands of the genre mean manuscripts under 70,000 words feel structurally thin to acquisitions editors. Readers expect a full, plot-dense experience, and the word count reflects that expectation.
Epic fantasy and science fiction are the genres where longer manuscripts are most accepted. 100,000–150,000 words is a normal range, but debut authors are generally advised to stay under 120,000 words to avoid print cost penalties that could push the retail price above what readers in the category expect to pay. This is discussed in detail in community conversations on r/writing as well.
Young Adult fiction averages 55,000–80,000 words across contemporary, fantasy, and thriller sub-genres. Middle Grade fiction, aimed at readers aged 8–12, targets 20,000–55,000 words, with adventure and fantasy titles sitting toward the upper end.
Picture books aren't measured in thousands. The professional standard is 500–800 words total for books aimed at ages 3–8, which is a constraint that shapes every editorial and design decision.
Novellas sit between short stories and full novels at 17,500–40,000 words. They're difficult to place with traditional publishers but perform well as self-published ebooks. If you're writing in this format, How to Write a Novella covers the structural and publishing considerations specific to shorter-form work.
Nonfiction Genres
Memoir follows conventions similar to literary fiction: 70,000–90,000 words is the industry standard, with agents cautious of first-time memoirists exceeding 100,000 words. If you're working on a memoir, How to Write a Memoir outlines the structural approach that keeps books within that range without cutting the story short.
Business nonfiction typically runs 45,000–80,000 words. The rise of the idea-driven business book has made shorter manuscripts of 45,000–55,000 words increasingly common and commercially viable, as Jerry Jenkins notes. Self-help books average 45,000–70,000 words, with readers and editors tolerating shorter lengths when the content is practical and clearly structured.
Why Word Count Affects More Than Just Length
Word count determines spine width, and spine width affects whether your book can display its title on a retail shelf. At a standard 6×9 trim size with 60 lb cream interior paper, a 70,000-word book produces approximately 220–240 pages and a spine wide enough for readable text in a bookstore. A thinner book can't carry that. See Book Thickness, Trim Size & Perception and Choosing the Right Trim Size and Paper for a full breakdown of how those decisions connect.
Print-on-demand platforms price per page, so a 120,000-word manuscript in the wrong genre doesn't just signal a mismatch, it costs more per unit to produce and may force a retail price above what readers expect to pay in that category. This is something Friesenpress and Career Authors both flag as a production reality authors need to plan for early.
Typesetting choices (font size, leading, margins, and chapter opening styles) can shift a manuscript's final page count by 10–15% in either direction. That's why word count and typesetting need to be planned together, not treated as separate decisions. Professional typesetting and page layout directly shapes how a manuscript's word count translates into a finished book.
Canadian authors self-publishing and distributing to both Canadian and US retailers work within the same genre benchmarks as the broader North American market. There's no meaningful regional difference in word count expectations. Self-publishing removes the agent gatekeeping step, but it doesn't remove the market expectation: a self-published thriller at 45,000 words will be perceived by readers as incomplete regardless of how it was published. For authors planning digital distribution, Kindle Self-Publishing explains how word count affects ebook production and platform requirements. How to Publish a Book is a useful starting point for understanding the full production pipeline, including where word count planning fits.
Frequently Asked Questions About Book Word Counts
How do I count the words in my manuscript?
Use the word count function in Microsoft Word (found under the Review tab) or Scrivener's Project Statistics panel. Both tools count only the words in your main text. Don't include front matter or back matter in the number you report to agents. They want the manuscript body count only.
Does word count differ for ebooks versus print books?
No. The manuscript word count is identical for both formats because they originate from the same source file. A print book has a fixed page count set by typesetting, trim size, and paper weight. An ebook has no fixed pages: the text reflows based on the reader's device and font size. Word count is the only length metric that applies equally to both formats.
What is the shortest published book?
Among widely published literary novels, Ernest Hemingway's The Old Man and the Sea (1952) is frequently cited at approximately 27,000 words, though it was serialised before book publication. For authors today, anything under 40,000 words is classified as a novella rather than a novel by most agents and publishers, per Reedsy.
What is the longest published book?
Tolstoy's War and Peace (1869) is approximately 580,000 words. Marcel Proust's In Search of Lost Time, published between 1913 and 1927, totals over 1.5 million words across its seven volumes. For context, debut authors are advised by Jerry Jenkins and others to stay well under 120,000 words in most genres.
What are the most common word count mistakes first-time authors make?
The two most frequent mistakes are overwriting and underwriting. Overwriting (producing a 130,000–150,000-word debut in a genre where 80,000–90,000 is standard) raises production costs and signals inexperience. Underwriting (submitting 45,000 words as a full novel) frustrates readers and reviewers. Both are avoidable by researching genre benchmarks before you start drafting. How to Self-Publish a Book You Can Be Proud Of covers the planning decisions, including word count, that shape a professional result. The Self-Publishing Checklist is also a useful tool for making sure word count targets are locked in before production begins.
How does word count affect the physical appearance and cost of a printed book?
Word count controls page count, which sets spine width, perceived value, and per-unit printing cost. At a 6×9 trim on 60 lb cream paper, every 250–300 words adds roughly one page. A 70,000-word book produces approximately 220–240 pages, thick enough for a readable spine on a retail shelf. A 40,000-word book in the same trim produces roughly 130 pages and a spine too thin to display a title clearly. Print-on-demand services charge per page, so an oversized manuscript also raises your unit cost and forces a higher retail price.
Are word count expectations different for Canadian authors?
No. Canadian authors targeting the North American market work within the same genre-specific word count benchmarks as authors in the US and UK. There are no meaningful regional differences in reader or agent expectations, whether you're distributing through Canadian retailers, US platforms, or both.
