Roboto has a dual nature. It has a mechanical skeleton and the forms are largely geometric. At the same time, the font features friendly and open curves. While some grotesks distort their letterforms to force a rigid rhythm, Roboto doesn’t compromise, allowing letters to be settled into their natural width. This makes for a more natural reading rhythm more commonly found in humanist and serif types.
This is the normal family, which can be used alongside the Roboto Condensed family and the Roboto Slab family.
Updated July 31 2013: Hinting has been improved and a fix made to ỡ, the Vietnamese 'o with horn and tilde' character. If you have installed the fonts on your computer, please download them again and re-install.
