System Fonts
System fonts are the default typefaces installed on an operating system or device, such as Arial on Windows, San Francisco on macOS/iOS, or Roboto on Android. They are used by applications and websites to display text without requiring additional font downloads, ensuring consistent rendering across platforms. This concept is crucial in web development and UI design for optimizing performance and maintaining native look-and-feel.
Developers should use system fonts to improve website loading times and reduce external dependencies, as they eliminate the need for web font downloads. This is particularly important for performance-critical applications, mobile-first designs, and projects targeting users with slow internet connections. System fonts also help maintain platform consistency, making interfaces feel more native and accessible across different devices.
