The Tiny Gallery project builds small, enclosed plinths, and places them on pedestrian-friendly Calgary streets.  The project aims to bridge the gaps between street art, gallery art, and public art, simultaneously helping local artists reach a larger audience and making art more accessible to the general public. Tiny Gallery also encourages pedestrian exploration of Calgary communities and promotes locally-owned businesses.

Physically, a Tiny Gallery plinth has a similar footprint to a Canada Post Street Letter Box, but is about 2.1 m (7 feet) tall. The middle, main section of the gallery consists of a polycarbonate-walled box, approximately 45 cm (18 in) wide x 45 cm (18 in) deep x 60 cm (24 in) tall, which is the actual exhibit space. The whole structure is topped with a water-proof, sloped roof. Art contained within a Tiny Gallery plinth is thus protected from wind and precipitation, though not from cold, heat, or sunlight.
