Calculate the estimated reading time of an article using JavaScript

Have you ever wondered how long it would take for your readers to go through that captivating article you’ve just penned down? In this blog post, we’ll explore a fascinating JavaScript technique that lets you estimate the reading time of an article. Imagine providing your audience with a heads-up on the time investment they’ll need—talk about a personalized touch!

Decoding the Reading Time Estimation

The Basics

Let’s start with the basics. The reading time of an article is commonly measured in words per minute (WPM), with an average adult reading around 200 to 250 words per minute. Armed with this information, we can create a simple JavaScript function to estimate the reading time.

Here’s a breakdown of the function:

  • wordsPerMinute: This variable represents the average reading speed in words per minute. You can adjust this based on your audience’s reading habits.
  • content.split(/\s/g).length: This line counts the number of words in the content by splitting it using whitespace as the delimiter.
  • minutes = words / wordsPerMinute: This calculates the estimated reading time in minutes.
  • Math.ceil(minutes): Finally, we round up the result to provide a whole number of minutes.

Putting it Into Action

Now, let’s put this function into action. Suppose you have an article stored in a variable called articleContent. You can easily calculate the estimated reading time like this:


And there you have it! With just a few lines of JavaScript, you can provide your audience with a personalized estimate of the time investment needed to dive into your content. It’s a small touch that can enhance the user experience and keep your readers engaged.

So, the next time you’re fine-tuning your blog or content-heavy website, consider implementing this reading time estimation feature. Happy reading and happy coding!
