1. GeneratePress
GeneratePress is the theme most often named when people talk about speed, and it backs that up with a specific number: a fresh install adds less than 10 KB (gzipped) to your page size. It takes full advantage of the block editor and works with page builders too.
2. Neve
Neve is designed around Core Web Vitals. Its developer, Themeisle, says its lightweight codebase and small size keep overhead low. It works with the block editor, page builders and WooCommerce.
3. Kadence
Kadence describes itself as lightweight yet full featured. You get a header and footer builder and starter templates in the free version, so you don’t need extra plugins for common design tasks.
4. Blocksy
Blocksy is a fast, modern theme with full block editor support. It’s a good choice if you want a quick site built mostly with native WordPress blocks.
5. Astra
Astra’s developer calls it lightning-fast, with clean code and a mobile-first design. It’s the most popular theme on this list, so it’s well tested with plugins.
6. Hello Elementor
If you use Elementor, Hello Elementor is the lightest starting point. It’s minimal on purpose and optimized for performance, leaving the design to Elementor.
7. Twenty Twenty-Five
WordPress’s default block theme lets you design everything with core blocks, so you don’t need a page builder. Fewer plugins usually means a faster site.
How to keep your WordPress site fast
- Use good hosting. A slow server will slow any theme. See our Hostinger review or Rocket.net review for options.
- Compress and resize images before uploading them.
- Use a caching plugin or your host’s built-in caching.
- Keep plugins to the ones you need, and avoid heavy sliders and animations.
- Test your pages in Google’s free PageSpeed Insights tool after each big change.
