Source Sans Pro is an open-source grotesque typeface designed by Paul D. Hunt for Adobe Systems. The design was inspired by American gothics, however, some traits such as the tail on the lowercase l are more reminiscent of humanist typefaces. The slightly condensed letterforms of Source Sans Pro make it ideal for user interfaces where space is a concern. It’s available in a full set of six weights with corresponding italics.
