Behind the Design

Sonic designed this protractor around the practical realities of a classroom. The thick body is a deliberate choice: thin protractors tend to slide or slip when students try to lift them, so adding body thickness addresses a small but consistent friction point. The acrylic resin material keeps the scale clearly visible while the 9cm diameter fits standard notebook pages without overhanging the edge.

A clear acrylic protractor sized for classroom use, with a thick body that makes it easy to pick up off a desk. The scale is printed for readability, and the 9cm diameter keeps it compact without sacrificing precision.
