A humanist sans serif font designed by Steve Matteson.
Open Sans was designed with an upright stress, but still feels humanist due to its open apertures, double-decker g, and humanist italic. It has a similar x-height to Verdana, but has a lighter stroke weight, and even more clarity (legibility) at smaller sizes. The bold feels a bit heavy, but retains legibility. There is also a semi-bold for use when the bold is too heavy.
Open Sans comes in 10 styles. It holds up well cross browser. The whole family is available on both Typekit and Google Web Fonts.
