Measure with Confidence Using Staedtler Mars Triangular Scales

Staedtler Mars Triangular Scales are precision tools trusted by architects, engineers, and drafters for accurate measuring and scaling of technical drawings. The triangular shape offers a comfortable grip and keeps the scale from rolling off work surfaces, making it practical for daily professional use.

Each scale is made from durable, high-impact polystyrene plastic and features clearly imprinted graduations designed to last. Color-coded grooves make it easy to identify and select the correct scale quickly, helping improve speed and accuracy when working with detailed plans. Available in both architect and engineer styles, each scale includes three sides and six different measurement ratios.
