Nothing here is summarised. These are the files themselves, fetched from YouTube on , so you can search them for the rules we quote on the home page and check the numbers yourself. YouTube ships layout changes without notice — a dimension is only true as of the date it was checked.
These are YouTube's files, not ours. We host archived copies because YouTube's build URLs rotate and stop resolving; the original URL for each is given below, so you can compare our copy against the live one for as long as it lasts. We claim nothing about them except the few rules we quote.
| File | What it is | Used for |
|---|---|---|
| www-main-desktop-home-page-skeleton.css |
YouTube's desktop home-page skeleton stylesheet, build ee8698c4, served
verbatim.
Fetched from https://www.youtube.com/s/desktop/ee8698c4/cssbin/www-main-desktop-home-page-skeleton.css
|
Desktop home grid — 310 × 174 px |
| www-main-desktop-watch-page-skeleton.css |
YouTube's desktop watch-page skeleton stylesheet, same build, served verbatim.
Fetched from https://www.youtube.com/s/desktop/ee8698c4/cssbin/www-main-desktop-watch-page-skeleton.css
|
Desktop watch sidebar — 168 × 94 px |
| desktop-search-thumbnail.json.txt |
An excerpt of the ytInitialData payload served with a
youtube.com/results search page — an excerpt, not the whole payload.
Weaker evidence than the two stylesheets: this is a size YouTube declares in data, not a CSS box we measured.
|
Desktop search result — 360 × 202 px |
| ytmweb-extract.css ytmweb-url.txt |
Rules extracted from the m.youtube.com stylesheet bundle. The full
bundle is 409 KB; we kept only the rules we cite, and the URL it came from is in the
second file so you can fetch the whole thing.

Mobile web home feed — 393 × 221 px, title clamped to 2 lines |
