    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.

    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.
    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.

    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.
    Length—For easy handling and storage, rulers that are 96" or longer come in multiple pieces that line up to create a complete ruler.

    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.
