HTTP Archive 2025 Web Almanac Reveals Stagnant Accessibility and Growing Page Weight

Web Page Bloat and Accessibility Concerns Highlighted in 2025 Web Almanac

The HTTP Archive’s 2025 Web Almanac, analyzing 17.2 million websites, has been released, offering a comprehensive look at the current state of the web. The report reveals continued challenges in web accessibility and a significant increase in page weight, despite advancements in web technologies.

Why This Matters

Ideal web development aims for fast, accessible, and lightweight experiences, but real-world implementations often fall short. The continued prevalence of accessibility failures, like missing focus styles on 67% of sites, impacts usability for millions of users. The 202.8% increase in median mobile page weight since 2015 directly translates to slower load times, increased data costs for users, and a poorer overall experience, costing businesses potential conversions and impacting SEO rankings.

Key Insights

• Page Weight Increase: Median mobile page weight grew from 845 KB in 2015 to 2,362 KB in 2025.
• Variable Font Adoption: 39.4% of desktop websites and 41.3% of mobile websites use at least one variable font.
• ARIA Usage: ARIA labels are used on 70% of websites, with 29% usage on buttons specifically.

Practical Applications

• Use Case: E-commerce sites should prioritize image optimization and JavaScript bundling to reduce page weight and improve conversion rates.
• Pitfall: Overusing ARIA attributes without proper semantic HTML can create accessibility issues, rather than resolving them.
