If you’re building a new website in 2025 and care about speed, performance, and simplicity, you’ve likely asked: “Which theme should I choose?”
Whether you’re a blogger, small business owner, or affiliate marketer, the answer might be simpler than you think.
GeneratePress is a lightweight WordPress theme for speed, and after testing it against other popular themes this year, it still leads the pack.
What Makes a WordPress Theme “Lightweight and Fast”?
Before diving into the tests, let’s clarify what we mean by a lightweight WordPress theme:
- Minimal file size (GeneratePress is under 10KB gzipped)
- No bloated features or unnecessary scripts
- Optimized for fast load times and Core Web Vitals
- Clean, well-coded structure that plays nicely with caching & CDN tools
In short, lightweight themes are designed to do more with less—and that’s exactly what you need to rank higher, retain users, and boost conversions.
What Is GeneratePress?
GeneratePress is a performance-focused WordPress theme built by developer Tom Usborne, loved by both beginners and pros alike.
Why it stands out:
- 🔹 Free & Premium versions available
- 🔹 Modular system: activate only what you use
- 🔹 Seamlessly integrates with Gutenberg and GenerateBlocks
- 🔹 Compatible with all major page builders (but you won’t need one!)
With a fresh install, GeneratePress adds less than 10KB to your site—yes, really.
Fun fact: No jQuery is loaded by default, which helps avoid render-blocking issues.
