TheChromeOS core fonts, also known as theCroscore fonts, are a collection of threeTrueTypefont families: Arimo (sans-serif), Tinos (serif) and Cousine (monospace). These fonts are metrically compatible withMonotype Corporation'sArial,Times New Roman, andCourier New, the most commonly used fonts onMicrosoft Windows, for which they are intended as open-source substitutes.[1][2]
Google licenses these fonts fromAscender Corporation under theApache License 2.0.[3][4][5]
The fonts were originally developed bySteve Matteson as Ascender Sans and Ascender Serif, and were also the basis for theLiberation fonts licensed byRed Hat under another open source license.[2] In July 2012, version 2.0 of the Liberation fonts, based on the Croscore fonts, was released under theSIL Open Font License.[6]
The fonts are also available at theNoto fonts repository atGitHub.[7]

In 2013, Google released an additional Crosextra (ChromeOS Extra) package, featuring Carlito (which matches Microsoft'sCalibri) and Caladea (matchingCambria).[8] These two fonts are respectively metric-adjusted versions ofLato[9] and Cambo,[10] both available atGoogle Fonts.
