DOM element count and the Core Web Vitals
31.5% of audited sites (63,552) keep their DOM between 400 and 799 elements (99% good INP, 45ms median), while the 17.6% exceeding 1,500 DOM nodes drop to 99% good INP (58ms median).
25.2% of sites use 800 to 1,499 DOM elements DOM element count, and 99% of those sites have a good INP, against 99% of all sites.
31.5% of sites use 400 to 799 DOM elements DOM element count, and 89% of those sites have a good LCP, against 86% of all sites.
Core Web Vitals pass rate
Sites with 800 to 1,499 DOM elements DOM element count have a good INP most often: 99%, against 99% of all sites. Sites with under 400 DOM elements DOM size have it least often, at 98%.
Sites with 400 to 799 DOM elements DOM element count have a good LCP most often: 89%, against 86% of all sites. Sites with 1,500+ DOM elements DOM size have it least often, at 84%.
DOM element count usage
400 to 799 DOM elements is the most used: 31.5% of sites. 800 to 1,499 DOM elements is 25.2% of sites.
Understanding DOM element count
How DOM tree size taxes style recalculation and layout during interactions
Every time a user taps a menu, filters a grid, or toggles a class, the browser recalculates styles and layout across affected DOM nodes. Across 63,552 sites (31.5%) with 400 to 799 elements, 99% pass field INP at a 45ms median, and the 25.2% between 800 and 1,499 elements reach 99% good INP (48ms median). Once the document tree crosses 1,500 elements (17.6% of sites, 35,503), good INP drops to 99% and median INP rises to 58ms.
Keep total DOM element count under 800 nodes on initial load and below 1,500 nodes on complex templates. Render modals, drawer menus, and offscreen tabs lazily on interaction, and paginate or virtualize long product and comment lists. Across all audited sites, 31.5% sit at 400 to 799 nodes (99% good INP, 45ms median) versus 17.6% at 1,500+ nodes (99% good INP, 58ms median).
How DOM element count plays out per platform
What the field data shows when you isolate a single CMS or framework.
WordPress 65,509 sites WordPress pages with 1,500+ DOM elements (15.9%) pass field INP at 99% vs 100% at 400 to 799 nodes.
Across 65,509 WordPress sites, 37.3% have between 400 and 799 DOM nodes (100% good INP, 45ms median) and 15.9% exceed 1,500 nodes (99% good INP, 56ms median).
