Table of the Test Results

Below you’ll find a summary of the performance results for each theme. We used the “PageSpeed mobile score” KPI to rank them, but the total loading page metric is also important, so don’t forget to look at that row.

Key takeaways:

  • All the themes go from acceptable to very good for their grade on PageSpeed Insights. There are either in orange or in green, there are none in red in terms of performance. 
  • Astra seems to be the fastest of the lightweight themes, with a 91/100 on mobile and a 2,1 s page load. 
  • Avada (with its own builder) also makes it to the top of the list with an 87/100 on mobile and a 2,4s page load. 

How We Tested the Themes 

Our selection was based on 2023 popularity, high numbers of downloads or sales on Envato, and quality reviews. Then we run an audit through the following performance tools:  

Powered by Lighthouse, PageSpeed Insights, and GTmetrix, both analyze the performance and the user experience of your website. The most important KPIs are the Core Web Vitals which come with a detailed report about how your pages perform and what are areas for improvement. That’s why we have included the 10 following metrics in our tests – measured on mobile

From PageSpeed Insights:

  • PageSpeed mobile score 
  • First Contentful Paint
  • Largest Contentful Paint
  • Cumulative Layout Shift
  • Speed Index
  • Time To Interactive
  • Total Blocking Time

From GTmetrix:

  • Total Loading time
  • Total page size 
  • HTTP requests

Then, we chose 10 themes that we divided into two categories: 

#1 The free and lightweight themes that come with a minimalistic approach and are more like a basic canvas to start a website:

  • Hello
  • Astra 
  • OceanWP
  • GeneratePress
  • Kadence

#2 The other category contains the “heavier” themes that come with their own page builder. We thought comparing Avada (and its Fusion builder) with a lightweight theme like Astra would be unfair. So the themes for the second category are the following:

  • Avada (Fusion builder)
  • Divi (Divi Builder)
  • BeTheme (BeBuilder)
  • The 7 (Elementor/WP Bakery page builder)
  • Salient (WPBakery page builder)

The Testing Sites

For the first category, we built a realistic test site using the WordPress Editor, and we used the blocks to create a hero banner with a button, 5 testimonials with pictures, 1 call to action (full section with an image), 4 icons and text, 2 titles and 2 subtitles and 8 services with pictures.

For the second category, we made sure every time to build a page with similar elements present in each builder: a hero banner with an image and a button, 3 services with icon and texts, 2 images (we re-used the same), 2 text elements, 3 icon lists, and a call to action section with a header, sub-header and button (full section).

By following the same testing scenarios and the same content for each theme, we could conduct a fair performance comparison analysis. We did a new installation for each theme and used the same server for each theme’s speed testing. 

⚠️ Important: Those tests have been performed on a server based in France, and we built each page ourselves. The results we have presented are from our own experience, and the results may differ according to the size of the images you upload, the amount of content you use, or even your location around the world.

Give an Extra Performance Boost with WP Rocket

WP Rocket is one of the best caching plugins for WordPress that can optimize any theme in a few clicks. It also improves the performance of your site and your Core Web Vitals

To understand the large impact of WP Rocket on speed, let’s see it in action with BeTheme, which was the “slowest” theme in our tests. 

For the record, there were a few issues flagged by Lighthouse, listed under the “Opportunities” tab:

The recommendations include using caching, enabling text compression, reducing unused CSS/JS, and deferring offscreen images.

We activated WP Rocket on that test site, and we noticed a huge improvement:

All our performance KPIs also improved thanks to WP Rocket which also improved the PageSpeed Insights score (my site moved to the green with a 98/100) score. 

WP Rocket also boosted the Core Web Vitals score and decreased the total loading time (from 4.1s to 2.1s). WP Rocket also reduced the page size and the number of HTTP requests:

To fix all the PageSpeed Insights warnings and boost the performance KPIs, we activated the following WP Rocket features:

  • Implement caching and text compression upon activation of the plugin:

Which is the Best Theme For You?

It’s almost impossible to suggest you one single theme as it depends on your specific needs and your client brief, but here are a few takeaways:

  • If you have a client willing to take over his website, update the content, and access the WordPress dashboard, then choosing a theme with a page builder may be easier (like BeTheme or the 7).
  • If you are a freelancer looking for a theme with greatly designed demos for different industries, then Divi and BeTheme may be your best choices. 
  • If you plan on creating an advanced WooCommerce site with thousands of products, a lightweight theme like Astra may be wiser. Plus, it comes with advanced WooCommerce features. 
  • If you need to create your own forms, and product layouts and add dynamic data to your website, then a theme bundled with Elementor Pro is a great option. Elementor was one of the first companies to launch the WooCommerce builder, allowing you to build your own product template and shop page in no time. 
  • If you are hesitating between a few themes, install one of their demos and look at them on mobile. Responsiveness should be essential when building a website.
  • If you are a web and design agency, Divi offers the Divi Cloud, where you can easily store your project and share it with the team. The collaboration and potential modifications can be done faster from everywhere.

Finally, choose a theme with fast support, recent updates, and accurate documentation. For example, OceanWP has an academy that offers webinars and tutorials to use the theme to its fullest. 

Wrapping up

Now, you should be able to decide and choose the right WordPress theme for your next project. And remember, no matter which theme you choose for your next project, WP Rocket is the easiest way to improve the speed of your WordPress site and pass the performance audits on PageSpeed Insights.
