    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.

    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.

    Center Finding

    Style A

    Center Finding

    Style B

    Line up these rulers exactly where you need them—they're clear plastic, so you'll never lose sight of what you're measuring. A staple of most sewers' kits, they're especially useful when working with intricate designs, lines, and patterns. All are laminated to protect their graduations from scratching and fading.
    Center Finding—These rulers come with a center-finding scale, so you can quickly locate the center of workpieces without any math. Just align the scale so that the same measurement appears on both sides of the object—zero marks your center.
    Red Graduation Marks—Easier to read than black graduation marks when measuring over black lines and text.
    Stainless Steel Edge—Best for cutting and inking straight lines, these rulers have a stainless steel edge that guards the plastic from nicks and stains.
