Wooden Ruler – FSC Certified, Extra Thick & Durable, Inch and CM

Extra Thick FSC-Certified Wooden Ruler – 12 Inch / 30 cm

This extra thick FSC-certified wooden ruler features both inch and centimeter measurements and is crafted from durable solid hardwood for long-lasting classroom, art, and everyday measuring use.

A longtime classroom favorite, this sturdy ruler is noticeably thicker and stronger than most standard wooden rulers. The solid hardwood construction resists bending and breakage, making it a reliable tool for students, artists, and makers who need a measuring tool that stands up to daily use.

Made in Germany from sustainably harvested FSC-certified wood, it offers a plastic-free alternative while maintaining accuracy and clarity. The clearly printed standard and metric markings make it easy to switch between measurement systems for math lessons, crafts, and creative work.

A small drilled hole at one end allows the ruler to be hung from a hook, clipped to a binder, or stored on a classroom peg for easy access.
