Tape Measures

The best of the best tape measures for everyday tasks—from Stanley to Lufkin to Milwaukee. Built to last, these tape measures have a coating on the blade that prevents the graduations from wearing or scratching off. Their durable plastic case won't crack when tossed into tool bags or dropped on the ground.

Starrett with Calibration Certificate

Image of Product. Front orientation. Tape Measures. Starrett.

When precision measurements are required for quality control or by regulation, use a tape measure that includes a calibration certificate traceable to NIST. The certificate states that the tape measure has passed a test for accuracy, so you can be confident your measurements are correct and consistent.

Long Tape Measures

With a blade long enough to measure a semi-trailer, these tape measures extend 50 ft. or farther.

Starrett with Calibration Certificate

Coated Steel Blade—A coating prevents the graduations from wearing or scratching off. Made of steel, these blades stay stiff when extended and won't stretch if pulled too hard, so they maintain their accuracy over time. They also keep their shape if dragged over rough surfaces, such as concrete.

Vinyl-Coated 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.

Diameter-Measuring Tape Measures

Wrap around duct, pipe, and other cylindrical objects to find their diameter without complex calculations. These tape measures are ideal for already mounted objects since you don't need to take your system apart. Also known as tree tapes.

Vernier Scale with Calibration Certificate

Our most precise diameter-measuring tape measures. Wind the blade around your object until the top scale aligns with the bottom vernier scale, then add the values together to find your diameter. These tape measures include a calibration certificate traceable to NIST, so you can be confident your measurements are correct and consistent.

Stainless Steel Blade—The choice for outdoor and wet environments, these blades won't rust if rinsed or rained on.

Blue Blade—White markings pop against the blue background, so you can read these tape measures in dimly lit areas.
