    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.

    Our economical option. These rulers are about as lightweight as plastic rulers, so they're convenient to carry from site to site. Although light, they're not flimsy—they resist snapping if knocked around in your toolbox. Plus, they'll keep their bright finish if frequently rinsed.
    Length—For easy handling and storage, 4 meter rulers come in two pieces that line up to create a complete ruler.

    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.

    For repeated height and depth measurements, stick these rulers to walls, tanks, and other vertical surfaces. Their numbers are printed from bottom to top or top to bottom, so you don't have to tilt your head to read them. Since these rulers permanently adhere to surfaces, they free up your hands as you work—no more lining up rulers or tape measures.

    Easy-Read Rulers

    From bright outdoor jobsites to dimly lit workshops, take measurements where standard metal rulers would be hard to see. The black finish on these rulers reduces glare, while the light-colored graduations pop against the dark background.
    Lightweight Aluminum
    Image of Product. Front orientation. Rulers. Easy-Read Rulers.
    Our economical option. These rulers are about as lightweight as plastic rulers, so they’re convenient to carry from site to site. To keep them looking like new, an anodized coating guards them from daily wear and protects their finish if rinsed or rained on. Etched into the material, their graduations won't rub off like printed graduations can.

    Half-Measure Adhesive-Back Rulers

    Take division out of the equation when building half-scale models and prototypes. The distance between the graduations on these rulers is half the printed measurement—just use your object's true dimensions to get a model half its size. Stick these rulers to your bench top for a permanent, hands-free measuring guide.
