The Perfect Pi Diameter Circumference Tape Measure (Model DCT120) is built for those moments when a standard tape just doesn’t cut it—like sizing pipe, measuring tree trunks, or checking round stock. This flexible, retractable steel tape gives you both standard measurements and outside diameter (OD) readings in one compact tool.

For everyday measuring, the top side shows consecutive inches down to 1/16 inch. Flip it over for diameter measurements down to 1/100 inch, helping you move from “wrap-around” measuring to useful OD readings quickly. You also get metric markings down to millimeters on both sides, with high-contrast numbers that stay easy to read on the job.
A reflective aluminum rotating wheel brake makes retract control straightforward and boosts visibility, while the strong magnet on the case lets you stick it to metal surfaces when you want it close at hand.
