Why Page Size Matters
Page size directly affects load time, bandwidth consumption, and user experience. Larger pages take longer to download, especially on mobile connections or slow networks. Excessive page weight increases hosting costs, hurts search rankings, and frustrates visitors. Monitoring page size helps you identify optimization opportunities and track the impact of performance improvements.
What Contributes to Page Size?
HTML
The base document containing your page structure. HTML is typically small but can grow with inline styles and scripts.
CSS
Stylesheets controlling your page's appearance. CSS files can become large with frameworks, unused rules, and lack of minification.
JavaScript
Scripts adding interactivity. JavaScript is often the largest resource type, especially with frameworks and libraries.
Images
Pictures, graphics, and icons. Images frequently dominate page weight when not properly optimized.
Fonts
Custom web fonts adding typography. Font files can be surprisingly large, especially with multiple weights and styles.
Other Resources
Videos, audio, PDFs, and other embedded media.
