Are you an aspiring author, editor, or publisher trying to figure out how long your manuscript will be in book form? Look no further! Our Book Length Calculator is a quick and accurate tool that helps you estimate how many pages your book will have based on the total number of words and the average number of words per page.
Whether you’re writing a novel, eBook, thesis, or nonfiction manuscript, knowing your book’s approximate length is essential for planning your layout, printing costs, or digital formatting. Our easy-to-use online tool gives you fast results and takes the guesswork out of the publishing process.
What Is a Book Length Calculator?
A Book Length Calculator is a simple tool that determines the estimated number of pages in a book by using the total word count and the average number of words per page.
This helps authors and publishers understand the physical or digital length of a manuscript before formatting or printing begins.
Formula Used in the Book Length Calculator
The formula used to calculate the book length is:
Book Length = Total Number of Words ÷ Average Words Per Page
This calculation provides an estimated page count based on how densely the content is packed on each page.
For example:
- If your book has 60,000 words and each page holds 300 words:
- 60,000 ÷ 300 = 200 pages
This estimation helps with cost planning, design decisions, and understanding your manuscript’s scope.
How to Use the Book Length Calculator
Using the Book Length Calculator on our website is simple and requires only two inputs:
Step-by-Step Guide:
- Enter the Total Number of Words
Type the total word count of your manuscript into the first input box labeled “Total Number of Words”. - Enter the Average Words Per Page
This is typically between 250–350 words per page for most printed books. Enter the average based on your formatting or genre. - Click “Calculate”
Hit the “Calculate” button to get an instant result. - View Your Estimated Book Length
The tool will display the estimated number of pages based on your inputs.
Example Calculation
Let’s say you are writing a fantasy novel that is approximately 95,000 words long. You expect about 275 words per page based on your formatting.
- Total Words = 95,000
- Average Words Per Page = 275
Now divide:
95,000 ÷ 275 = 345.45
So, your estimated book length would be approximately 345 pages.
Why Book Length Estimation Matters
Knowing the estimated page count of your book can help you:
Estimate Printing Costs: Printers often charge per page. Knowing your length helps avoid surprises.
Plan for Book Formatting: It affects margins, font size, and spacing choices.
Meet Publisher Requirements: Many publishers specify ideal manuscript lengths.
Set Reader Expectations: Genres often have standard page counts. Readers of romance novels, for example, expect a different length than those of epic fantasy.
What Is the Average Words Per Page?
Here are some general guidelines for average words per page, depending on book format and layout:
| Format | Average Words per Page |
|---|---|
| Paperback (Fiction) | 250–300 words |
| Non-fiction | 300–350 words |
| Academic Textbooks | 400–500 words |
| Large Print Books | 200–250 words |
| E-books (variable) | Depends on device size |
You can modify the average based on your layout preferences or publisher requirements.
