Have you ever asked how long should my book be? Did you know what a great question it is? GREAT question! Many debut authors dive into their manuscript with wild abandon and with little thought to structure, plot or word count.

How Long Should My Book Be Guide to Word Count

When you’re planning a book (even if you’re a pantser) it’s important to know a few things about your genre ahead of time—things like, well, what genre it is. And what the theme is. And how many words it will be. Yeah. Even word count should be pre-planned.

And I know how weird that sounds if this is the first time you’re hearing it. What!? There’s a word count for novels!? Yup. And it’s kind of one of those things you should abide by unless you’re crazy-famous and/or already a successful author (because obvs these guidelines don’t apply to you) or you don’t care about selling books. Because word count matters. And the rules change for every genre.

So, your first task is to figure out what genre your book is in. After that, check the list below to find the answer to your question how long should my book be?
