    About High-Quality Rulers
    industrial info icon

    What separates a throwaway ruler from one you’ll keep for decades, which type is best for everyday use, and how to compare materials.

    Rulers

    Your go-to rulers for everyday measuring. Whether metal for durability or wood for a classic feel, our rulers measure up to most tasks, from woodwork to textiles to rough machining.
    Corrosion-Resistant Stainless Steel
    Image of Product. Front orientation. Rulers. Rulers, Corrosion-Resistant Stainless Steel.
    Our most corrosion-resistant rulers. These rulers won't rust when rinsed, rained on, or wiped down with degreasers or cleaning solutions. They're hardened to prevent dents and scratches, so you can trust they'll last for years to come. Etched and filled with black ink, their graduations won't rub off like printed graduations can.
    Calibration Certificate—When precision measurements are required for quality control or by regulation, use a ruler that includes a calibration certificate traceable to NIST. The certificate states that the ruler has passed a test for accuracy, so you can be confident your measurements are correct and consistent.
    Length—For easy handling and storage, rulers that are 96" or longer come in multiple pieces that line up to create a complete ruler.

    Antislip Backing

    A cork backing grips the surface beneath these rulers, preventing them from sliding around and scratching delicate material. Made of stainless steel, these rulers won't rust when splashed with water or wiped down with degreasers or cleaning solutions. They're hardened to prevent dents and scratches, so you can trust they'll last for years to come. Etched and filled with black ink, their graduations won't rub off like printed graduations can.

    Heavy Duty Steel
    Image of Product. Front orientation. ZoomedIn view. Rulers. Rulers, Steel.
    Our strongest rulers for your toughest industrial jobs, from building heavy machinery to processing raw materials. These rulers resist nicks and dents, so they’ll measure accurately even after hard hits and drops. However, they’ll weigh down your tool belt more than aluminum and stainless steel rulers will. Bold, deeply etched, and blackened with ink, their graduations are easy to read and won’t rub off like printed graduations can.

    Hard Maple
    Image of Product. Back orientation. Rulers. Rulers, Hard Maple.
    Handcrafted in Maine from kiln-dried, hard maple, these wood rulers will stay straight and true for years to come. Just like rulers from a century ago, they also get all the details right:
    • Etched lines and numbers won’t wear off like printed graduations.
    • A clear coating guards against nicks and scratches.
    • Seamlessly integrated brass endcaps keep the corners square and the ruler lying flat.
    • 1/4" thickness prevents pencils and chalk from slipping as you trace lines.

    Rulers for Cutting

    Don't nick your fingers while measuring and cutting straight lines. These rulers have either a safety guard or groove to keep your fingers out of the way. A rubber backing grips the surface beneath them, so they won't slide around.

    High-Accuracy Rulers

    With tolerances tight enough for machining detailed parts, these rulers are the most accurate we offer. They're also the most precise, with graduations as small as 1/64", so you can trust them for even the tiniest dimensions. Also known as machinists' rules.
    All are precision made and etched in the U.S. to meet federal standards. Made of tempered steel for extra strength, they keep their shape even after multiple hard hits and drops, so they'll measure accurately for years to come. Their graduations are deeply engraved and blackened with ink, meaning they won't rub off like printed graduations can.
    Satin Chrome-Plated Steel
    Image of Product. Front orientation. Rulers. High-Accuracy Rulers, Chrome-Plated Steel.
    Tough enough to handle most tasks, these rulers are chrome plated to resist rust. Their satin finish reduces glare for easy reading.
    Starrett Rulers—These rulers are manufactured by Starrett, one of the most trusted names for precision measuring tools.
    Calibration Certificate—When precision measurements are required for quality control or by regulation, use a ruler that includes a calibration certificate traceable to NIST. The certificate states that the ruler has passed a test for accuracy, so you can be confident your measurements are correct and consistent.

    Magnetic High-Accuracy Rulers

    Take machine-shop-accurate measurements while keeping your hands free. These rulers have magnets on both ends to cling to most metallic surfaces. Also known as machinists’ rules, they have the tightest tolerances we offer. They’re also our most precise, with graduations as small as 1/64", so you can trust them for even the tiniest dimensions.

    Circumference-Measuring Rulers

    Finding the circumference of duct, pipe, and other cylindrical objects is as easy as pi. Just measure the diameter of the object's opening with the inch scale, then look at the measurement below—that's your circumference. Since you only need access to the opening, these rulers are ideal for pipe and duct that are already mounted. A favorite among sheet metal workers, they're also known as tinners' rules.
