Back in mid-2013, I wrote a post called, “The Bootstrap Boom is Just Getting Started“. Looking at the statistics, it was clear that Bootstrap was on its way to becoming very popular indeed.

Three years later, and its obvious that even those optimistic projections underestimated just how popular Bootstrap would become. Not only has Bootstrap grown since 2013. According to a range of statistics, its usage has actually grown by between 800% to 1,000%

The image below shows Bootstrap’s market share in 2013, according to At that time, Bootstrap ran 1.6% of Quantcast’s top million sites.

How did Bootstrap become so popular?

A large portion of Bootstrap’s growth has come thanks to the support of CMS’s and frameworks.

Bootstrap is baked into the Laravel 5 and Joomla 3 core and so it is the obvious choice on those platforms, but it also dominates when it is not the default choice.

The most popular Drupal 8 theme is Bootstrap.


In the WordPress world, I looked in January 2013 and only found 8 WordPress themes using Bootstrap and several of those weren’t on

In mid-2013, there were 30 themes on that supported Bootstrap.

Now in 2016, there are 250 Bootstrap themes on! ThemeForest has another 2,500 Bootstrap themes for WordPress!

You’ll also find numerous Bootstrap themes for Magento, eZ Publish, Typo3 and more. Even SASS platforms like Shopify now have Boostrap designs available.

Want to learn to use Bootstrap? Head over to Amazon and you’ll find hundreds of web design books that feature Bootstrap. These books show you how to integrate Bootstrap with everything from Javascript frameworks like Angular.js and Knockout.js to languages such as Ruby on Rails and In contrast, you’ll find less than 20 books about other frameworks such as Zurb Foundation.
