How Long Should Your Book Be?
Getting the length of your book right is essential for meeting reader expectations. This guide provides word count guidelines for various genres.
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.
