Behind the Design

This ruler addresses a common classroom frustration: students often struggle to draw margins at consistent offsets while also needing to measure distances accurately. Sonic solved this by putting both functions on one ruler, using color-coded markings to distinguish the margin scale from the zero-start scale so there's no confusion mid-lesson.

The PMMA construction keeps the ruler thin at just 2mm, and the included name sticker means it can be labeled immediately, which matters when dozens of identical rulers end up in the same classroom.

An 18cm ruler designed with two scale types on a single edge: a margin scale for drawing lines from a set offset, and a zero-start scale for measuring distances directly. Color-coded markings make it easy for students to tell the two apart at a glance.
