Behind the Design

Sonic designed this triangle ruler set with two consistent friction points in mind: rulers that are hard to pick up off a flat surface, and scales that don't start at the edge, making zero-reference measurements awkward.

The 1.5mm thickness strikes a balance, giving enough body to slide a finger underneath without adding bulk that would interfere with drawing lines. The zero-start scale runs flush from the tip on both pieces, so measurements read directly without offset arithmetic. The acrylic keeps markings visible under light without distorting the line underneath.

A two-piece acrylic triangle ruler set in 30-degree and 45-degree angles, sized at 12cm for everyday schoolwork. The body is thick enough to grip and lift easily from the page, and the scale starts at zero for straightforward measuring.
