Questions about Roboto Flex

Answered from its licence, Google Fonts and each app’s own font list

Is Roboto Flex free for commercial use?

Yes. Roboto Flex is under the SIL Open Font License 1.1 , which allows commercial use at any scale, logos, websites, apps and PDFs included.

How do I download and install Roboto Flex?

FontKind doesn’t host Roboto Flex’s files: it comes free from Google Fonts . On its page there, choose Get font, then Download all, and unzip the file. It holds one variable file for every style, and a static folder with a file per style: install one set or the other, not both. On Windows or a Mac, double-click each font file and choose Install, then restart any app that was open, Word included.

Is Roboto Flex in Microsoft Word?

Not until you install it: Roboto Flex isn’t one of Microsoft 365’s cloud fonts. Installed, it is in Word’s font menu and PowerPoint’s. On Windows, its weights beyond Regular and Bold show as fonts of their own, such as Roboto Flex Thin and Roboto Flex Black. For someone who hasn’t installed it, turn on Embed fonts in the file in Word’s save options: its licence allows that.

Is Roboto Flex in Google Docs?

Most likely. Search for Roboto Flex under More fonts in the font menu of Docs; added there, it is in Sheets and Slides too.

Yes: Roboto Flex is in Figma’s font menu with all ten weights, in the browser and the desktop app, with nothing to install.
