SF Buttacup Lettering Font

SF Buttacup Lettering by ShyFoundry is a free geometric sans caps font with a crisp, modernist feel. The letters pair near-monoline strokes with broad round curves and blunt, squared endings, so the overall look feels clean and pared back rather than neutral.

That makes this free font a natural fit for posters, book covers, packaging, title cards, and simple wordmarks where a short line of type needs a cool, graphic voice. It also works well for monograms, initials, and cover lines, because the round forms and hard vertical cuts give even a few letters a strong, poster-like presence.
