Variable fonts

Variable fonts will save significant space in apps and operating systems, cutting down on download speeds, load times, and server costs. They’ll make the web typographically richer, and give designers new tools to create beautiful designs. Variable fonts will also help create single fonts that work as well on large screens, like desktops, as they do on modern devices with small screens, like wearables.
