Professional drafting scales engineered for studio precision

Dimensional accuracy matters when you're translating design concepts into precise measurements. Staedtler manufactures these scales from specially selected plastics engineered for stability, they won't warp with temperature shifts or flex under pressure during repeated use. Color-coded grooves along each edge provide instant visual identification of scale ratios, eliminating the frustration of hunting for the right edge mid-project.

The architect scale offers ten ratios (3/32, 3/16, 1/8, 1/4, 3/8, 1/2, 3/4, 1, 1 1/2, and 3) for residential and commercial design work, while the engineer scale provides six decimal ratios (10, 20, 30, 40, 50, and 60) for civil projects and site plans. Graduations are laser-etched rather than printed, so measurements remain legible through years of handling and erasing. The solid white plastic construction stays lightweight for comfortable drafting sessions while maintaining the rigidity needed for accurate line work. At twelve inches, these scales fit standard drafting setups without overwhelming smaller workspaces, delivering professional-grade precision for students through seasoned practitioners.
