Questions about Monaspace Argon
Answered from its licence, Fontsource and each app’s own font list
Is Monaspace Argon free for commercial use?
Yes. Monaspace Argon 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 Argon?
FontKind doesn’t host Monaspace Argon’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-argon adds it in one line.
Is Monaspace Argon in Microsoft Word?
Not until you install it: Monaspace Argon 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 Argon ExtraLight and Monaspace Argon 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 Argon in Google Docs?
Probably not: the More fonts list in Docs draws on Google Fonts, and Monaspace Argon 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.
