About this artwork

Since the late 1960s, John Knight has addressed the ideologies of built and designed space, often through
existing systems of visual communication not generally associated with art making. The title phrase of
his important early work One Inch to a Foot makes obvious reference to scale notations on architectural plans. It is etched in one-inch high, Helvetica letters on the plate of a standard overhead projector; once projected, each letter measures one foot in height. Thus a representational convention of architectural plans is physically enacted, and the work carves out real space as well: the projector requires 15 feet of distance from the wall in order to execute the title statement. One Inch to a Foot is technically portable but always establishes a direct relationship to its site of installation.
