Webflow uses a 32x32 pixel favicon size by default because it aligns better with modern web and device standards, unlike the older 16x16 pixel size that was standard in earlier browsers.
1. Modern Display Standards Favor 32x32
- Most modern browsers and operating systems (especially on high-DPI or Retina screens) prefer larger favicons for better clarity.
- A 32x32 favicon scales down effectively for smaller uses (like in tabs) and looks sharper on high-resolution displays.
2. Webflow Optimizes for Best Compatibility
- Webflow automatically generates a set of favicons and touch icons in various sizes, but the running favicon (used in browser tabs) defaults to 32x32 for optimal balance between compatibility and clarity.
- This size works well across desktop browsers (Chrome, Firefox, Safari, Edge) and scales visually on different device resolutions.
3. 16x16 Is Outdated for Most Use Cases
- The traditional 16x16 pixel favicon still works but appears pixelated or blurry on modern displays.
- It's retained only for legacy compatibility. Web standards have moved to support icons up to 196x196 or more for mobile and PWA contexts.
Summary
Webflow defaults to a 32x32 pixel favicon to deliver a clean, sharp appearance on modern high-resolution displays while maintaining backward compatibility. This size is now the de facto standard for favicons in modern web design.
