Website speed is easy to talk about and harder to measure well. This page brings together the most useful current benchmarks: the latest monthly Chrome UX Report pass rates, the 2025 HTTP Archive performance research, page weight data and content management system comparisons. Every statistic has its source beside it, so you can check the context before you quote it.

Current CrUX Core Web Vitals pass rates
The Chrome UX Report (CrUX) is built from real visits by Chrome users who have opted in to share usage statistics. Google publishes a monthly summary of how many origins meet the good threshold for each metric. These figures cover all device types together.
Statistic 1: The August 2026 CrUX dataset covered 18,294,881 origins.
Statistic 2: 68.1% of origins had good Largest Contentful Paint in August 2026.
Statistic 3: 81.5% of origins had good Cumulative Layout Shift in August 2026.
Statistic 4: 85.3% of origins had good Interaction to Next Paint in August 2026.
Statistic 5: 55.6% of origins passed all three Core Web Vitals in August 2026.
Statistic 6: The July 2026 dataset covered 18,059,068 origins.
Statistic 7: In July 2026, 68.3% of origins had good LCP.
Statistic 8: In July 2026, 81.6% of origins had good CLS.
Statistic 9: In July 2026, 85.7% of origins had good INP.
Statistic 10: 55.7% of origins passed all Core Web Vitals in July 2026, so the overall pass rate was essentially flat from July to August.
Statistic 11: The June 2026 dataset covered 18,210,974 origins.
Statistic 12: In June 2026, 67.7% of origins had good LCP.
Statistic 13: In June 2026, 81.4% of origins had good CLS.

Chart A: Chrome UX Report pass rates, August 2026
Share of 18,294,881 origins meeting the good threshold. All device types combined.
View the data as a table
| Measure | Share of origins |
|---|---|
| Interaction to Next Paint (INP) | 85.3% |
| Cumulative Layout Shift (CLS) | 81.5% |
| Largest Contentful Paint (LCP) | 68.1% |
| All Core Web Vitals | 55.6% |
The overall pass rate is lower than any single metric because a site must pass all three to count. LCP is the metric most often holding sites back.
What good actually means
Google publishes a good threshold for each Core Web Vital. A page is assessed at the 75th percentile of real visits, so most visitors, not just the fastest, need a good experience.
Statistic 15: Good Largest Contentful Paint means the main content loads within 2.5 seconds.
Source: Google Search Central, Core Web Vitals (opens in a new tab)
Statistic 16: Good Interaction to Next Paint means the page responds to interactions in less than 200 milliseconds.
Source: Google Search Central, Core Web Vitals (opens in a new tab)
Statistic 17: Good Cumulative Layout Shift means a score of less than 0.1, so content does not jump around as it loads.
Source: Google Search Central, Core Web Vitals (opens in a new tab)
Google recommends that site owners achieve good Core Web Vitals for success with Search and for a good user experience generally. It is important to keep this in proportion. Core Web Vitals are part of how Google evaluates page experience, not a standalone ranking score, and relevant, helpful content still matters most. A fast page with weak content will not outrank a slower page that answers the search much better. Speed is best treated as a quality baseline that supports everything else in your SEO work.
LCP statistics
Largest Contentful Paint measures when the biggest visible element, usually a hero image or heading block, finishes rendering.
Statistic 18: 62% of mobile websites and 74% of desktop websites had good LCP in 2025.
Source: HTTP Archive Web Almanac 2025, Performance chapter (opens in a new tab)
Statistic 19: An image was the LCP element on 76.0% of mobile pages and 85.3% of desktop pages.

Statistic 20: Good First Contentful Paint was achieved by 55% of mobile websites and 70% of desktop websites.

Statistic 21: Good Time to First Byte was achieved by only 44% of mobile websites and 55% of desktop websites. A slow server response delays every later milestone, including LCP.
Source: HTTP Archive Web Almanac 2025, Performance chapter (opens in a new tab)
Because images dominate LCP, the most effective fixes are usually correctly sized images, modern formats, giving the hero image loading priority and avoiding lazy loading on the first visible image. Server response time is the other common constraint, which is where good hosting and caching help.
INP statistics
Interaction to Next Paint measures how quickly the page visibly responds after someone taps, clicks or types. It is heavily affected by JavaScript running on the main thread.
Statistic 22: 77% of mobile websites had good INP in 2025, compared with 97% of desktop websites.

Statistic 23: Median Total Blocking Time was 1,916 ms on mobile and just 92 ms on desktop in 2025.

The gap between mobile and desktop here is striking. The same scripts that run comfortably on a laptop can hold up a mid-range phone for well over a second. Auditing third-party scripts, chat widgets, sliders and tracking tags is often the quickest route to better mobile responsiveness.
CLS statistics
Cumulative Layout Shift measures unexpected movement of content while the page loads, such as a button jumping just as you try to tap it.
Statistic 25: 81% of mobile websites and 72% of desktop websites had good CLS in 2025, so mobile performs better on this metric.
Source: HTTP Archive Web Almanac 2025, Performance chapter (opens in a new tab)
Statistic 26: About 9% of mobile websites and 10% of desktop websites had poor CLS.

Setting width and height on images, reserving space for embeds and loading fonts carefully prevent most layout shift problems.
Mobile vs desktop performance
Mobile has improved noticeably over the last three years, but it still trails desktop on most measures.
Statistic 27: 48% of mobile websites had good Core Web Vitals in 2025, compared with 56% of desktop websites.
Source: HTTP Archive Web Almanac 2025, Performance chapter (opens in a new tab)
Statistic 28: Mobile Core Web Vitals pass rates rose from 36% in 2023 to 44% in 2024 and 48% in 2025.

Statistic 29: Desktop Core Web Vitals pass rates rose from 48% in 2023 to 55% in 2024 and 56% in 2025, so mobile is closing the gap.

Our mobile web design statistics for 2026 look at how much browsing now happens on phones, which explains why these mobile gaps matter commercially.
Page weight and requests
Page weight is the total size of everything a page downloads. The Web Almanac compares it with Core Web Vitals results across millions of pages. The relationship is a correlation, but it is consistent across home pages, inner pages and device types.
Statistic 30: The median page weighed 2,164 KB on mobile and 2,412 KB on desktop.

CMS performance benchmarks
The Web Almanac CMS chapter compares real-user performance for sites built on different platforms. These results describe the typical site on each platform, including its themes, plugins and hosting. They do not prove that one platform will make your site fast or slow, because a well built site on any platform can perform well.

This finding comes from online stores and should not be applied directly to every type of website. It is still a useful reminder that small delays add up when people are comparing products and prices on their phones.
What the data means for your website
- Measure with real user data. Lab tests are helpful for diagnosis, but CrUX and Search Console show what your visitors actually experience.
- Fix LCP first on most sites. It is the metric with the lowest pass rate, and images are usually the cause.
- Audit JavaScript for mobile. The mobile INP and blocking time figures show that scripts hurt phones far more than desktops.
- Keep pages light. Pages under 1 MB pass Core Web Vitals far more often than pages of 5 MB or more.
- Choose build quality over platform labels. CMS averages vary widely, but the way a site is designed and built matters more than the badge on it.
Our small business website checklist includes practical speed checks you can run yourself. Every website we design is built with lean pages, sized images and minimal scripts from the outset. If you would like a second opinion on your own site's performance, you can get in touch.
Methodology and source notes
- Chrome UX Report figures are the monthly release notes for June, July and August 2026. They cover all origins in each dataset across device types. An overall Core Web Vitals figure for June 2026 is not included here because we did not rely on one.
- Web Almanac figures come from the HTTP Archive 2025 crawl combined with Chrome UX Report data for the sites in that crawl. Percentages refer to websites or pages as stated.
- CMS results reflect the typical site on each platform and include the effects of themes, plugins, hosting and content choices.
- The Shopify figure comes from Shopify's own 2026 analysis of active stores and applies to that ecommerce context.
- Thresholds are Google's published good thresholds for Core Web Vitals.
- We have not combined figures from different sources into a single number. Launch North created the charts on this page. The data belongs to the organisations credited beneath each chart.
