    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.

    Adhesive-Back Rulers

    Free up your hands when measuring length over and over—no more lining up rulers or tape measures. These rulers stick to everything from toolboxes to lathe beds for a permanent measuring guide.
    Extra-Flexible Plastic

    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.

    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.
    Lightweight Aluminum
    Image of Product. Front orientation. ZoomedIn view. Rulers. Rulers, Lightweight Aluminum.
    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.

    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.

    Adhesive-Back Vertical Rulers

    Image of Product. Front orientation. ZoomedIn view. Rulers. Adhesive-Back Vertical Rulers.
    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.

    Folding Rulers

    Combine the rigidity of a ruler with the portability of a tape measure. A favorite among carpenters, these rulers stay straight even when extended up to 6 ft., then fold up to the length of a phone to tuck into your tool belt. Bend them at their joints to draw angles and measure corners.
    Wood

    Image of Product. Front orientation. Rulers. Folding Rulers, Wood, Rulers with Extension.

    Rulers with Extension

    For those who prefer the warm look and feel of wood, these rulers are a classic choice. Just be sure to keep them dry, since moisture can cause them to warp and crack. To keep them turning smoothly, their joints are brass plated to guard against wear and rust. Brass caps cover their ends, so they won’t splinter.
    Rulers with Extension—Measure the inside of objects, such as drawers, where a standard folding ruler would either be too long or too short. These rulers have a sliding extension, so you can lengthen the ruler to fit within the object you're measuring.

    Rulers with Extension

    The choice for wet and outdoor environments, these rulers won't warp, fade, or crack if rinsed or rained on. Their joints snap into place when you bend them 90°, so they stay rigid as you measure and draw right angles.

    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.

    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.
    With Safety Guard

    These rulers have a barrier that blocks your fingers from the knife as you cut. They're safer to use with box cutters than rulers with a finger groove.

    Image of Product. Front orientation. Tape Measures. Pocket Diameter-Measuring Tape Measures.
    For quick diameter measurements on the go, these tape measures are as small as a pack of gum to tuck into your pocket. There's no math involved—just wrap the blade around your cable, pipe, or other cylindrical object. The number that overlaps with zero is your diameter. These tape measures are ideal for already mounted objects since you don't need to take your system apart. Also known as tree tapes.
    Automatic Blade Return—The blade zips back into the case when you let go.
    Nonlocking Blade Lock—Pull the blade out and hold it in place between your fingers. These free-moving tape measures are best for taking frequent, small measurements.
    Chrome-Plated Metal Case—Choose metal cases for your toughest industrial jobs, from construction to machining. These cases resist breaking due to hard hits and drops. However, they're heavier to carry around than plastic cases.
