Advice
Nonfiction
by Stewart Ferris
Trade nonfiction is generally shorter than a novel with the same number of ideas, because the reader came for a usable argument. Narrative nonfiction is the exception: it is sold as a story. Most general nonfiction sits between 50,000 and 80,000 words. When you do not yet know the house, plan for 60,000–75,000.
| Category | Typical range | Notes for a debut |
|---|---|---|
| Practical how-to | 30,000–50,000 | Short is a feature if the method is clear |
| Self-help | 40,000–70,000 | 45,000–60,000 is the busy-reader length |
| Business and money | 40,000–70,000 | Framework books often 45,000–55,000 |
| Thought-leadership business | 60,000–85,000 | Only if the research earns it |
| Health, parenting, relationships | 40,000–70,000 | Same band as self-help |
| Memoir | 60,000–90,000 | 70,000–85,000 |
| Biography | 80,000–110,000 | Major lives run longer; debuts should not |
| Narrative nonfiction | 70,000–100,000 | Scene-driven; judged like a novel |
| Popular history | 70,000–100,000 | Research-heavy titles can reach 120,000 |
| True crime | 70,000–100,000 | Close to narrative nonfiction |
| Local or illustrated history | 30,000–50,000 | Often photo-led |
| Essays | 40,000–70,000 | Sold on voice and a unifying idea |
| Cookbook (prose) | 20,000–40,000 | Headnotes plus method; recipes carry it |
| Illustrated / gift nonfiction | 15,000–40,000 | A designed object |
| Academic and reference | 80,000–120,000+ | Press guidelines override trade norms |
| Christian living / inspirational | 40,000–60,000 | Many houses want a tight, applicable book |
A memoir covers a slice of a life with a question running through it. Sixty thousand to 90,000 words is enough. A cradle-to-now autobiography is a different, harder sell, and length will not give it a shape.
Business and self-help readers are impatient in a useful way. A framework book at 45,000–55,000 — idea, evidence, steps, a few cases — often outsells a 90,000-word restatement of the same idea. Hybrid and traditional editors alike steer first books toward 40,000–60,000.
Narrative nonfiction, popular history, and true crime are stories with footnotes. Seventy thousand to 100,000 words matches what those editors acquire. A debut proposal that promises 150,000 words will be asked to shrink before contract. Local history is a separate, shorter market, often 30,000–40,000 words plus photographs.
