About High-Quality Rulers

What separates a throwaway ruler from one you’ll keep for decades, which type is best for everyday use, and how to compare materials.

Quickly locate the center of workpieces without any math. Just align these rulers so that the same measurement appears on both sides of the object—zero marks your center.

Corrosion-Resistant Stainless Steel

Image of Product. Front orientation. Rulers. Center-Finding 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.

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.

See-Through Rulers


Center Finding Style A	Center Finding Style B

Center Finding Style C

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.

Pocket Center-Finding Rulers

Find the center of workpieces on the go—these rulers are no bigger than a pen to tuck into your pocket. They come with a clip to keep them from falling out or getting misplaced. To find a center, align them so that the same measurement appears on both sides of the object. Zero marks your center—no math required.

Lightweight Aluminum

About as lightweight as plastic rulers, these rulers are convenient to carry from site to site. They keep their bright finish even if frequently rinsed.

Half-Measure Adhesive-Back Vertical Rulers

Measure height while building half-scale models and prototypes—no division required. 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. These rulers read bottom to top or top to bottom, so you don't need to tilt your head to measure vertically. Stick them to your bench top for a permanent, hands-free measuring guide.

High-Accuracy Combination Squares

Use these squares in place of your try square, miter square, depth gauge, height gauge, center-point finder, and level. Blades are labeled with numeric increments that are less than 1" for quick reading.

Heavy Duty Levels

These sturdy levels last longer than typical levels, even if you use them frequently. With four solid sides that form a box shape, they stay flat on surfaces without wobbling and won’t twist or deform over time. The aluminum housing and durable plastic vial won't crack if you step on them or drop them off a ladder or tool tray.

Levels with Ruler—Align and measure surfaces without having to switch tools.

Levels with Center-Finding Ruler—Quickly locate the center of your workpiece without any math. These levels have graduation marks that start at zero in the middle of the level. Just align them so that the increments are the same on both sides of the object you’re measuring —zero marks your center.
