Geometrica is a low contrast rounded geometric Sans with a mid 19th/early 20th century simplicity air yet modern and minimalist. The font was inspired by the idea of creating a typeface with uppercase/lowercase characters and small caps having the same proportion. The result is a font with a moderate width, generous x-height, and short ascenders and descenders, giving it a compact and clean look.Geometrica comes in 10 weights plus italics—each variant with 560 glyphs—and contains a number of OpenType features that allow you to create very ‘good looking’ designs.
