The latest web design statistics point to four practical priorities: improve mobile performance, reduce unnecessary page weight, make accessibility part of design and QA, and choose platforms for fit rather than popularity. The figures below come mainly from the 2025 Web Almanac, based largely on a July 2025 web crawl, and the WebAIM Million’s February 2026 automated accessibility analysis. They measure different samples and outcomes, so they are useful benchmarks—not interchangeable scores for every website.
How to read these web design statistics
The 2025 Web Almanac is based on HTTP Archive data; most figures here describe its July 2025 dataset. Its overview reports that more than 16 million websites were tested and 244 TB of data processed. The URL set draws on the Chrome UX Report, whose real-user data reflects Chrome users, while HTTP Archive also runs lab tests in controlled environments. In the described 2025 setup, mobile tests used an emulated Moto G4, a 4G-equivalent connection and U.S. Google Cloud locations; desktop tests used a Linux virtual machine and a cable-equivalent connection. The lab generally tests a home page and one secondary page, not every page or user state.

WebAIM’s February 2026 report is a different kind of study: it used automated WAVE evaluation on rendered versions of one million top-ranked home pages. Its detected-error counts are not a full accessibility assessment. Keep the observation dates and methods attached to the figures, and avoid treating a result from either study as a prediction for an individual site.

Core Web Vitals summarize loading, responsiveness and visual stability. In the Web Almanac’s 2025 summary, a page meets the “good” thresholds when LCP is within 2.5 seconds, INP is within 200 milliseconds and CLS is at or below 0.1. These are field-data classifications in the report, not a guarantee that every visit or page performs the same way.

| Measure | Result | What it tells designers |
|---|---|---|
| Sites with good Core Web Vitals, mobile | 48% in the 2025 HTTP Archive analysis | Fewer than half of the measured mobile sites met all three good thresholds. |
| Sites with good Core Web Vitals, desktop | 56% in the 2025 HTTP Archive analysis | Desktop was ahead of mobile in the same report. |
| Mobile sites with good Core Web Vitals, 2021 comparison | 32% in the 2021 series reported by HTTP Archive in 2025 | The 2025 result is higher, but it remains below half. |
| Desktop sites with good Core Web Vitals, 2021 comparison | 41% in the 2021 series reported by HTTP Archive in 2025 | The desktop share also improved over the comparison period. |
| Mobile sites with good Core Web Vitals, 2024 comparison | 44% in the 2024 series reported by HTTP Archive in 2025 | The one-year change to the 2025 result was modest. |
| Desktop sites with good Core Web Vitals, 2024 comparison | 55% in the 2024 series reported by HTTP Archive in 2025 | The measured desktop share edged upward. |
Popularity tier and page type change the picture, which is why a single blended benchmark can mislead:
| Slice of the 2025 HTTP Archive sample | Mobile good Core Web Vitals | Desktop good Core Web Vitals |
|---|---|---|
| 1,000 most popular sites | 51% | Not stated for this popularity tier in the cited comparison. |
| Next 10,000 sites | 42% | Not stated for this popularity tier in the cited comparison. |
| Next 100,000 sites | 37% | Not stated for this popularity tier in the cited comparison. |
| Next 1,000,000 sites | 42% | Not stated for this popularity tier in the cited comparison. |
| Next 10,000,000 sites | 48% | Not stated for this popularity tier in the cited comparison. |
| Home pages | 45% | 47% |
| Secondary pages | 56% | 61% |
Popularity-tier and page-type percentages are HTTP Archive’s 2025 findings; the report’s figures do not establish that popularity or page type itself causes a performance difference. The gap between home and secondary pages is a reason to test both, not just the page used in a design review.
Largest Contentful Paint and the hero image
LCP is the Core Web Vital most directly tied to when the main visible content appears. In HTTP Archive’s 2025 analysis, 74% of desktop pages had good LCP, compared with 62% of mobile pages; poor LCP occurred on 7% of desktop pages and 13% of mobile pages.
The LCP element was an image on 85.3% of desktop pages and 76.0% of mobile pages in that same analysis. Text was the LCP element on 14.4% of desktop pages and 23.7% of mobile pages. Among LCP images, 57% were JPG and 26% PNG. These results make the first large image a sensible design and implementation checkpoint, but do not imply that every hero image is the LCP element.
- HTTP Archive found that 51% of desktop LCP images and 44% of mobile LCP images were served from the same host as the page.
- Only 2.2% of desktop pages and 2.1% of mobile pages used preload for LCP resources.
- The
fetchpriority="high"attribute appeared on 16.3% of desktop pages and 17.3% of mobile pages. - About 16–17% of pages lazy-loaded the LCP image, according to HTTP Archive.
All four implementation figures are from the Web Almanac’s 2025 dataset. Their low or high prevalence is not, by itself, proof of a performance problem or a prescription to apply a technique everywhere. Identify the actual LCP resource first; avoid delaying it with lazy loading, and consider preload or high fetch priority only when the page’s resource discovery and measured behavior support it.
Page weight: images and JavaScript dominate
HTTP Archive’s 2025 page-weight chapter reports a median home-page transfer of 2.6 MB on mobile and 2.9 MB on desktop. A decade-long comparison puts the median mobile home page at 2,362 KB in July 2025, versus 845 KB in July 2015—a 202.8% increase. In the year-over-year comparison, median home-page weight grew 8.4% on mobile and 7.3% on desktop.
Rank #3
| Median home-page resource, HTTP Archive July 2025 | Mobile | Desktop |
|---|---|---|
| Total page weight | 2.6 MB | 2.9 MB |
| Images | 911 KB | 1,058 KB |
| JavaScript | 632 KB | 697 KB |
| Fonts | 122 KB | 139 KB |
| CSS | 77 KB | 82 KB |
| HTML | 22 KB | 77 KB |
These are medians for the measured home pages and resource categories, not budgets or recommendations for a particular design. The chapter also reports a median mobile inner-page weight of 1.8 MB in 2025. Since measurement began in 2022, median inner-page weight increased 27.8% on mobile and 25.2% on desktop.

Requests are another useful diagnostic, though request count alone does not describe total bytes or user experience. HTTP Archive counted a median of 72 requests on mobile pages and 77 on desktop pages in 2025; request counts rose 9% year over year on mobile and 8% on desktop. Audit the actual resources behind those requests: the report’s median mobile home page carried 911 KB of images and 632 KB of JavaScript.
Accessibility: automated scans find widespread barriers
WebAIM’s February 2026 Million report evaluated 1,000,000 home pages and detected 56,114,377 distinct accessibility errors. That works out to 56.1 detected errors per page on average, 10.1% more than the average in its 2025 analysis. The tested pages contained more than 1.4 billion page elements, averaging 1,437 elements per home page—a 14.3% increase in the average from the prior year. WebAIM reported detected errors on 3.9% of page elements, or about one in 26.
| WebAIM Million measure | February 2026 result |
|---|---|
| Sampled home pages with detected WCAG failures | 95.9% |
| Sampled home pages with detected WCAG failures in the 2025 comparison | 94.8% |
| Pages with a defined document language | 87.3% |
| English-language pages in the sample | 521,826 |
WAVE’s findings are signals for triage, not a complete conformance verdict: automated tools cannot detect every WCAG failure, and no detected error does not establish that a page is accessible. Combine automated scans with keyboard-only checks, manual review of focus order and interaction states, and testing with assistive technologies. Review content and flows such as forms, menus, dialogs and error messages in their actual context; a single home-page scan cannot represent the full site.
CMS results are associations, not platform rankings
WebAIM also compared detected-error averages among sampled pages identified with particular content-management systems. The table preserves its sample sizes and error averages so the figures are not mistaken for universal product scores.
| CMS identified in WebAIM’s February 2026 sample | Sampled pages | Average detected errors per page | Difference from all-page average |
|---|---|---|---|
| Adobe Experience Manager | 6,572 | 29.9 | 46.7% below |
| Squarespace | 2,669 | 33.0 | 41.2% below |
| Wix | 3,183 | 33.3 | 40.6% below |
| HubSpot CMS | 4,237 | 35.1 | 37.4% below |
| TYPO3 | 5,371 | 38.5 | 31.3% below |
| Drupal | 18,222 | 41.2 | 26.5% below |
| Joomla | 3,981 | 45.7 | 18.6% below |
| WordPress | 252,302 | 52.8 | 5.8% below |
| 1C-Bitrix | 8,769 | 106.5 | 89.8% above |
WebAIM’s system-level figures describe associations in its sample, not outcomes caused by the CMS. Theme and component choices, content, custom code, configuration and the sampled sites themselves can all differ. Use the table as context for questions to investigate—not as a substitute for testing the design and implementation you plan to ship.

The Web Almanac’s 2025 analysis found CMS use on 55% of desktop pages and 54% of mobile pages. WordPress appeared on 35% of mobile sites and accounted for 64% of CMS use in the report. Those prevalence figures describe adoption; they do not establish that a platform is faster, more accessible or better suited to a particular project.
| Ecommerce measure | HTTP Archive 2025 result |
|---|---|
| Analyzed desktop sites identified as ecommerce | 19.9% |
| Analyzed mobile sites identified as ecommerce | 19.2% |
| Ecommerce adoption among the top 1,000 sites | 1% |
| Ecommerce adoption in the top 10 million sites | 22% desktop; 21% mobile |
| Ecommerce adoption in 2022 | Approximately 17% on desktop and mobile |
| Ecommerce adoption in 2025 | About 20% on desktop and 19% on mobile |
The top-1,000 and top-10-million values refer to different popularity slices, while the 2022-to-2025 comparison describes change over time in the Web Almanac series. They should not be read as contradictory estimates for the same group. For a design decision, compare publishing workflow, product and checkout requirements, integrations, accessibility controls and measured performance on the actual pages—not market share alone.
What designers should do with the numbers
- Test the pages people use. Measure home pages and representative inner pages separately, on mobile and desktop. Compare field data with lab diagnostics rather than treating either as a complete picture.
- Inspect the first visible content. Find the LCP element on mobile and desktop, then verify that its image size, format, delivery and loading priority support prompt discovery and rendering.
- Reduce avoidable page weight. Start with image payloads and JavaScript, which occupy substantial portions of the median home-page transfer in HTTP Archive’s 2025 data. Check whether each resource is needed for the experience.
- Make accessibility checks part of design QA. Use automated scanning to find issues efficiently, then manually test keyboard use, focus behavior, labels, content structure and key interactions with assistive technologies.
- Choose platforms against requirements. Adoption and sampled error averages cannot predict your outcome. Prototype or audit the real theme, components and content model you intend to use.
Web design statistics are most useful as prompts for targeted testing. The strongest signal here is not a universal winning tool or platform, but the need to evaluate real pages by device, content type and user task.
