Google Fonts Knowledge is a rich library of guides to the world of typography, created by typographic experts from around the globe. This supplement to the Google Fonts catalog covers universal principles of typography for any medium, enabling designers and developers of all skill sets to choose and use type with purpose. The Google Fonts Knowledge library, as it stands today, consists of 30+ lessons spread out over three modules — Introducing Type, Choosing Type, and Using Type — in addition to 100+ glossary definitions. It’s not hard to become a good typographer, but it can sometimes be hard to demystify the art and science of typography itself. Google Fonts Knowledge aims to make these skills accessible to all.
