Questions about Monaspace Radon
Answered from its licence, Fontsource and each app’s own font list
Is Monaspace Radon free for commercial use?
Yes. Monaspace Radon 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 Monaspace Radon?
FontKind doesn’t host Monaspace Radon’s files: it isn’t on Google Fonts, and comes free from Fontsource , a library of open fonts. On its page there, choose Get font, then Download complete family, and unzip the file: it holds desktop fonts for every weight and style. On Windows or a Mac, double-click each font file and choose Install. For a website, npm install @fontsource/monaspace-radon adds it in one line.
Is Monaspace Radon in Microsoft Word?
Not until you install it: Monaspace Radon 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 Monaspace Radon ExtraLight and Monaspace Radon ExtraBold. For someone who hasn’t installed it, turn on Embed fonts in the file in Word’s save options: its licence allows that.
Is Monaspace Radon in Google Docs?
Probably not: the More fonts list in Docs draws on Google Fonts, and Monaspace Radon comes from Fontsource. Docs can’t add a font of your own, so set it in an app on your computer, such as Word, instead.
Is Monaspace Radon in Figma?
Not built in: Figma includes Google Fonts, and Monaspace Radon comes from Fontsource. Install it on your computer and Figma lists it.
