Are you an aspiring author or just curious about how many words you should aim for when writing a book?

If you’re short on time, here’s a quick answer to your question: There is no set number of words per page in a book as it depends on several factors such as font size, line spacing, and margins.

In this article, we will explore the different factors that affect the number of words per page in a book and provide some guidelines to help you estimate how many words your book should have.

Factors that Affect the Number of Words per Page

When it comes to determining how many words should be on a page in a book, there are several factors that come into play. Here are the top four:

  • Font Size: The size of the font used in the book is a major factor in how many words will fit on a page. Fonts come in all shapes and sizes, but most books use a font size between 10 and 12.
  • Line Spacing: The amount of space between each line of text can also have an impact on the number of words per page. Most books use a standard line spacing of 1.15 or 1.5.
  • Margins: The margins on a page determine how much white space there is around the text. The wider the margins, the fewer words will fit on the page.
  • Paragraph Length: Shorter paragraphs with fewer sentences can make a page look longer, while longer paragraphs can make a page look shorter.

It’s worth noting that there is no hard and fast rule for how many words should be on a page in a book. The number of words can vary widely depending on the book’s genre, target audience, and the preferences of the publisher or author.

Guidelines for Word Count in Different Genres

When it comes to writing a book, one of the most commonly asked questions is how many words should a page contain. The answer to this question depends on the genre of the book you are writing. Here are some guidelines for word count in different genres:


Novels can vary in length depending on the target audience and genre. Generally speaking, most novels fall within the range of 70,000 to 100,000 words. However, literary and historical fiction can be longer, often ranging from 100,000 to 150,000 words. Young adult and middle-grade novels are usually shorter, ranging from 40,000 to 70,000 words.

Memoirs and Biographies

Memoirs and biographies are typically longer than novels, as they require more space to tell the story of a person’s life. Memoirs are typically around 80,000 to 100,000 words, while biographies can be anywhere from 100,000 to 200,000 words or more.


Non-fiction books can vary widely in length depending on the subject matter. For example, a self-help book may be around 50,000 to 70,000 words, while a history book could be as long as 200,000 words. Generally speaking, most non-fiction books fall within the range of 70,000 to 100,000 words.

It is important to note that these guidelines are just that – guidelines. Ultimately, the length of your book should be determined by the story you want to tell or the information you want to share.

Tips for Estimating Word Count

Before starting to write a book, it’s crucial to have a rough estimate of how many words you’ll need. This will help you set goals, create a writing schedule, and plan your project. Here are some tips to help you estimate your book’s word count:

  • Use a Word Count Tool: There are several free online word count tools that can help you estimate how many words you’ve already written. This can be useful if you’re writing in chunks or sections and need to keep track of your progress. One such tool is WordCounter.
  • Look at Published Books in Your Genre: A good way to get a sense of how long your book should be is to look at other books in your genre. This will give you an idea of what readers expect and what publishers are looking for. For example, if you’re writing a romance novel, you’ll find that most publishers expect novels to be between 50,000 to 90,000 words.
  • Divide Your Outline into Chapters: Once you have an outline for your book, divide it into chapters and estimate how many words each chapter will be. This will give you a rough estimate of how long your book will be. Keep in mind that the number of chapters can vary depending on the book’s genre and structure.

By using these tips, you’ll be able to estimate the word count of your book and create a plan to help you achieve your writing goals.


In conclusion, the number of words per page in a book is not a fixed number and can vary depending on several factors.

However, by considering the guidelines provided in this article and using some estimation tips, you can have a rough idea of how many words your book should have.

Remember, the most important thing is to focus on writing a compelling story that engages your readers and keeps them hooked until the very end.
