It is not to be confused with a true unitless ratio. For example, one inch measured from a drawing with a scale of "one-inch-to-the-foot" is equivalent to one foot in the real world (a scale of 1:12).one inch measured from a drawing with a scale of "two-inches-to-the-foot" is equivalent to six inches in the real world (a scale of 1:6). In the United States, and prior to metrication in Britain, Canada and Australasia, architect's scales are marked as a ratio of x inches-to-the- foot (typically written as x″=1′-0″). Architect's scales may be flat, with 4 scales, or have a 3-lobed cross-section, with 6 or 12 scales. Scales were traditionally made of wood, but today they are usually made of rigid plastic or aluminum. įor accuracy and longevity, the material used should be dimensionally stable and durable. In common usage, both are referred to as a ruler.Īrchitect's scale A triangular architect's scale, made of brassĪn architect's scale is a specialized ruler designed to facilitate the drafting and measuring of architectural drawings, such as floor plans and Multi-view orthographic projections.īecause the scale of such drawings is often smaller than life-size, an architect's scale features multiple units of length and proportional length increments. A device for drawing straight lines is a straight edge or ruler. In scientific and engineering terminology, a device to measure linear distance and create proportional linear measurements is called a scale.
