How long should each chapter be?

Jeffrey's answer

My golden rule is around three thousand words. Around ten pages. But this depends very much on your personal choice, and what you are writing.

In the time of Dickens, chapters of thirty or forty pages were normal. People had longer evenings, fewer interruptions, slower lives. Today, readers like to move on faster. They like to break with one subject and meet a different one. They like the satisfaction of finishing a chapter on a Tuesday evening and starting a fresh one on Wednesday morning. The chapter, in our era, is the unit of attention.

Kane and Abel ended up at eighty-one chapters. It was never meant to be — that was just the way the book turned out. I could easily have made it forty chapters by joining two together. But I think readers get to the end of a chapter and they have to make a decision: do I read on? The fun I have, as a writer, is to make sure the answer is yes. That is the test of every chapter ending. Have you given the reader a reason to keep going?

Three thousand words is the rough target. Some chapters will run shorter — twelve hundred words, perhaps a single scene that has to land like a blow. Some will run longer — five thousand, perhaps, when a complicated set-piece needs the room. But the average should sit around three thousand. The reader’s attention can take that. Beyond that, you are starting to ask for forgiveness.

If you are writing your first novel and you do not yet know what your chapter rhythm is, my advice is simple. Write the first three chapters. Print them out. Hand them to a reader you trust — not your spouse, not your mother, but a friend who reads in your genre. Ask them: would you turn the page at the end of each chapter, or were you satisfied to put the book down? If they say satisfied, the chapter is too long. Cut it. Rewrite the ending. Make them turn the page.

The rhythm of chapters is the rhythm of a novel. Get it right and the book reads itself. Get it wrong and the reader puts the book down at the end of chapter eight, and they do not pick it up again.

A few practical notes

• Jeffrey’s golden rule: around 3,000 words per chapter. Around ten pages. That is the modern reader’s natural unit of attention.
• By genre. Modern thrillers: 2,000–4,000 words (Lee Child, James Patterson). Literary fiction: longer chapters tolerated, 5,000–8,000 (Hilary Mantel, Donna Tartt, Marilynne Robinson). Genre fiction: shorter is usually better.
• Why short chapters work. Reader feels progress. Natural break point. Hook can be planted every few thousand words. The reader who finishes a chapter on a train decides whether to start the next one — and short chapters bias them toward yes.
• Why long chapters work. Sustained immersion. Time to build a complex scene. Literary fiction tradition.
• Vary chapter length within a book. A 3-page chapter after three 6,000-word chapters is a punctuation mark. Variation is rhythm.
• Test it. Print the first three chapters. Hand them to a reader who reads in your genre. Did they want to turn the page at each chapter ending? If not, the chapters are too long.
• The Dickens exception. 30–40 page chapters worked in 1850 because evenings were long and competing entertainments were few. They do not work today, however well written. The chapter has to fit the era.
