At its core, the design of Sharp Sans is based upon the circle. When you look at Sharp Sans, you can see that every curve is circular, from the aperture of the “o” to the inner curve of the “s.” It isn’t a perfect circle mathematically—it’s what’s called an optically perfect circle, a “perfect” circle as most human eyes prefer it, very slightly wider than they are tall. From there, every letter of Sharp Sans only has a singly stroke width, and angles tend to be variations of 45 of 90 degrees. Sharp tells me that in addition to picking up influences from ITC Avant Garde, he was also inspired by Futura, Avenir, Gotham, and “Frutiger Frutiger Frutiger.” After putting all those influences in a blender, Sharp Sans was meant to be “an amalgam of everything that’s useful,” and an “embodiment of the platonic neoliberal sans serif.”
