jQuery Reading Time

jQuery Plugin to estimate the reading time of any element.

Installation

• Raw source: original / minified
• Download repository as .zip
• Bower: bower install jquery-readingtime

Usage

Call .readingtime() on any element, and it returns an integer with the estimated reading time in minutes.

Note: When called on multiple elements, it calculates reading time for the first element in the set.

Examples

Reading time on a single element.

$("article:first").readingtime();

Since the plugin only calculates the reading time for the first element, you can simply do:

$("article").readingtime();

To calculate reading time for multiple elements, just iterate:

$("article").each(function() {
  $(this).readingtime();
});

Options

Reading Time takes an options object, with two options.

• wpm: integer, reading speed in words per minute. Default: 250.
• round: string, Math method to call for rounding. Default: 'round'

Example:

$("article:first").readingtime({wpm: 300, round: 'ceil'});

Real-life example

How to use it to add an estimated reading time to every blog post:

// For each blog post
$("article").each(function(){

  // Calculate Reading Time
  var ert = $(this).readingtime();

  // Append it to post header if not zero
  if (ert > 0) {
    $(this).find('> header').append('<p>' + ert + ' min reading time</p>');
  }
});
