One of the most common questions new authors ask is: "How long should my book be?" The answer depends on your genre, audience, and goals. In this guide, we'll break down industry-standard word counts for different types of books.

Why Word Count Matters

Your book's length influences everything from reader satisfaction to printing costs and marketing. Readers expect certain lengths based on the genre, and publishers use word count as a quality benchmark.

Tips for Hitting the Right Word Count

Plan with an outline

Knowing your target length helps you shape your chapters and pacing.

Write now, edit later

Don't worry if your first draft is too long or short, editing will tighten it.

Focus on clarity

Readers care more about flow than hitting an exact word count.

Remember: These Are Guidelines, Not Rules

There's no magic number, but knowing the expected word count for your genre helps you stay market-ready. Some of the most successful books have broken these conventions:

  • Harry Potter and the Sorcerer's Stone: 76,944 words (longer than typical middle grade)
  • The Great Gatsby: 47,094 words (shorter than typical adult fiction)
  • Gone Girl: 145,000 words (longer than typical thriller)
