Typical chapter length
Key takeaway: Choose length to fit pace. Short chapters speed up. Long ones slow down.
A chapter is a main division of a book. Chapter length varies, but many run roughly 1,500 to 5,000 words depending on genre and style.
| Book type | Typical chapter length |
|---|---|
| Thriller | 1,000 to 2,500 words |
| General fiction | 2,000 to 4,500 words |
| Fantasy | 3,000 to 6,000 words |
| Non-fiction | 2,000 to 5,000 words |
| Middle grade | 1,000 to 2,500 words |
The formula
Key takeaway: Chapter length = total words ÷ number of chapters.
An 80,000-word novel with 25 chapters averages 80,000 ÷ 25 = 3,200 words per chapter.
| Total words | Chapters | Average |
|---|---|---|
| 60,000 | 30 | 2,000 |
| 80,000 | 25 | 3,200 |
| 100,000 | 20 | 5,000 |
Check total length by genre first.
Plan the chapters with an outline.
Let the story decide
Key takeaway: End a chapter at a turn, a question or a change.
Break when a scene ends or tension peaks. Vary length. A short chapter can land a shock.
Format chapters
Start each chapter on a new page in print. Keep headings consistent. Check your interior file.
