Typical scales used in the United States are:įull scale, with inches, divided into sixteenths of an inch A 1:5 architectural scale (inches to feet) would be a 1:60 unitless scale (inches to inches) since there are 60 inches in 5 feet. 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 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 Australia, 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 asymmetric 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. and Fairgate.Ĭustom imprinted promotional products for architect, engineers, building trades industry schools please visit Promotional Products Store the source for custom imprinted products with a lasting value and long term presence.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 are often smaller than life-size, an architect's scale features multiple units of length and proportional length increments.įor accuracy and longevity, the material used should be dimensionally stable and durable. Therefore, it is not necessary to use the symbol mm. It should be noted that all dimensions in metric dimensions are in millimeters. Construction details may be drawn to metric scales of 1:20, 1:10, or 1:5.

Metric floor plans are drawn in a ratio of 1:50. This scale is very close to the scale 1/8" = 1'-0" (1:96). For example, metric plot plans are often drafted in ratios of 1:100. A ratio is the relationship of one measurement to another. Metric scales are usually based on ratios. One meter is slightly larger than one yard. You have to get used to measurements expressed in meters (m) and millimeters (mm). Metric measurements is the standard in most of the world.
