Roboto is a sans-serif typeface from Google.
Start with Google’s other releases — Noto Sans. They come from the same studio that drew Roboto, and A1 has 2 websites using them.
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.
A1 features 11 websites using Roboto, including Studio Meraki, Integrated Biosciences, and Origin. They lean towards Photography, Sans-serif, and Scroll animation design styles, and they’re most often built with Wordpress, Webflow, and Framer.
