    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.
    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.

    Vertical Rulers

    No need to read sideways when measuring height and depth—the numbers on these rulers are printed from bottom to top or top to bottom.
    Corrosion-Resistant Stainless Steel with Easy-Align Hook End
    Image of Product. Front orientation. ZoomedIn view. Rulers. Vertical Rulers, Corrosion-Resistant Stainless Steel with Easy-Align Hook End.
    Similar to a tape measure, these rulers have a hook on one end to catch the edge of an object, keeping them straight as you measure. They're crafted from a single piece of metal, ensuring the hook always stays aligned with the scale.
    Made of stainless steel, 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.

    Inch/Metric

    Use these blades with Starrett High-Accuracy Combination Square Heads. They meet Fed. Spec. GGG-R-791, which establishes uniform standards for accuracy, graduations, and size. Blades are labeled with numeric increments that are less than 1" for quick reading. All have a corrosion-resistant satin chrome-plated finish that reduces glare and wear-resistant etched markings.

    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.

    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.
