Google Sans is a geometric sans-serif typeface designed by Google for use as a corporate branding face. The design is based off Product Sans but with slight optimizations that make it more functional as a text face. Product Sans was only intended for use in Google’s product logos, whereas Google Sans is meant to be more of an all around workhorse family. The font has begun to be seen more frequently in Google products—there are plans to bring it to Chrome OS, and it has been split tested in mobile search results. It also has been used sporadically in the new Gmail redesign where it is still mixed awkwardly with their previous branding face Roboto.
