What font does YouTube use?

YouTube uses Roboto for its interface — video titles, channel names, descriptions, and comments are all set in Roboto across the web and mobile apps. Roboto is Google's own sans-serif typeface, so the choice mirrors the rest of Google's products.

YouTube's logo and brand marks use YouTube Sans, a proprietary typeface it introduced in 2017. That font is reserved for branding, not for the body text you read on the site.

Roboto is what you actually read on YouTube. It is an open-source sans-serif designed by Christian Robertson for Android and adopted across Google's ecosystem. Because it is free under the Apache License, anyone can download it from Google Fonts and use it in their own designs.

YouTube Sans is the custom typeface built for the brand — the wordmark, promotional graphics, and product identity. It is proprietary and not offered as a public download, so you will not find an official YouTube Sans file to install.

Roboto: yes. It is free and open source, available directly from Google Fonts for web and desktop use.

YouTube Sans: no. It is a protected brand asset. Designers who want a similar tone usually reach for a clean geometric sans-serif alternative, but there is no official public YouTube Sans package.

The font YouTube renders (Roboto) is separate from the “fancy fonts” people put in video titles, channel handles, and comments. Those eye-catching styles are Unicode characters — pre-styled bold, italic, cursive, and decorative letters — not a font setting you toggle on your channel.

That is why a channel name can appear in a script or bold style even though YouTube itself only draws Roboto: the characters themselves carry the styling, so they survive being pasted anywhere. Note that handles have their own character rules, and heavily decorated text can hurt search and accessibility — see how Unicode fonts work.
