Solid Icon Sets

Ultimate is the the world’s largest icon family, designed by one team of experts over twelve years. You'll find every concept here, from common themes to rare icons. Used by some of the most recognized designers in the world, Ultimate is the set you reach for when you want a neutral set that has it all.

Core is the Helvetica of icons. It is timeless. Each icon is stripped to its essential form and has generous inner spacing. This ensures legibility even at the smallest sizes. Core is the workhorse of interface design, and it is a set that we will continue to expand.

Flex is a fluid icon family inspired by nature’s curves. It replaces rigid geometry with smooth, flowing forms. It’s more organic and expressive than Core (neutral) but subtler than Plump (chunky, playful). Read about the design process.

Sharp combines pure geometry and bold structure for a brutalist, high-tech feel. It’s raw, trendy, and unapologetic. It pairs best with typefaces that have strong construction, such as Futura, Gill Sans, or Space Mono.
