Koala Tools Ring Ruler 360

Ideal for artists, architects, engineers, educators, craftspeople, woodworkers, quilters, and pattern makers, the Koala Tools Ring Ruler 360 is the first size-adjustable, circular ruler. It makes drawing and measuring circles and arcs a much simpler and more efficient experience by eliminating the cumbersome pivot-point system.

Expanding and contracting the Ring Ruler 360 feels natural and ergonomic. It's quicker and safer than using a needle compass, and it also provides the more useful circular metrics of diameter and arc length/circumference.

One of the best features of the Ring Ruler 360 is its simplicity. This makes it a great learning tool for students — especially those too young to handle a compass.

The Koala Tools Ring Ruler 360 is offered in your choice of US standard and metric scales.
