Audiobook Length Calculator
Have you ever listened to a story being read out loud? That is called an audiobook. Sometimes, we want to know how long it will take to finish listening to one. That’s when an Audiobook Length Calculator becomes very helpful. Let’s learn more about it in a fun and easy way!

Why Do We Need to Calculate Audiobook Length?
Sometimes we want to know how much time it will take to finish an audiobook. This helps us plan our day or week. For example:
An audio book length calculator helps us do this quickly and easily!

How Does an Audiobook Length Calculator Work?
An audiobook length calculator uses simple math. It usually needs just two things:
- Total words in the book
- Reading speed (words per minute)
Here’s how it works:
Step 1: Find the Total Words in the Book
Books have different lengths. A short story may have 5,000 words, while a big novel might have 100,000 words or more. You can find the word count online, or you can estimate it.
Step 2: Choose the Reading Speed
Different people read at different speeds. Most audiobook narrators read between:
- 130 to 160 words per minute (WPM) if they are reading slowly and clearly.
- 170 to 200 WPM for a faster reading style.
Let’s say the book has 60,000 words, and the reading speed is 150 WPM.
Now do this:
60,000 ÷ 150 = 400 minutes
That’s 6 hours and 40 minutes of listening time!
You Can Also Use Audiobook Speed Settings
Most audiobook apps allow you to change the playback speed. This means you can listen faster or slower.
If the audiobook is 8 hours long, and you listen at 1.5x speed, you can finish it in:
8 ÷ 1.5 = 5.3 hours (around 5 hours and 20 minutes)
Online Tools for Audiobook Length
There are many easy websites and apps that can do the math for you. You just enter:
Then, the tool tells you how long the audiobook will be. Some tools also help you plan how many minutes to listen each day to finish on time.
