Ratio 3 is a contemporary art gallery based in San Francisco's Mission district. For the past fifteen years, the gallery's focus has been on providing professional representation to a small group of emerging and mid-career artists. The gallery's goal is to foster each of their artist's careers through long-term support and promotion. Ratio 3 emphasizes curatorial intent within a commercial gallery, with exhibition programming that provides varied, experimental and intergenerational contexts for their represented artist's practices.
