font inspectorWhat font does YouTube use?
YouTube is one of the most visited sites in the world, and it runs on a free font anyone can use. We inspected the logged-out home page, which shows only the sidebar and a sign-in prompt, so the sample of text is small.
Short answer: YouTube’s interface uses Roboto, loaded from Google Fonts. On the logged-out home page every piece of text was set in Roboto, at weights 400 and 500.

The font stack
The main font stack in the CSS:
font-family: Roboto, Arial, sans-serif;- Interface text is small and uniform: 14px for labels and 12px for secondary text.
- Only two weights are in use, 400 and 500. Medium, not bold, marks emphasis.
- YouTube also has a brand typeface, YouTube Sans, for marketing and some headings. It did not appear on the page we inspected.

How we checked
We opened youtube.com in Chrome on September 20, 2026 and read the computed styles of its visible text: the declared font stack, the font actually rendered, and how much of the page’s text each family sets. That is the same data the Font Inspector extension shows under Fonts on this page. We re-check these pages periodically, and the date above shows the last inspection.
