A carpenter tape measure is designed to meet the distinct needs of woodworking and carpentry. Moreover, its design incorporates a robust, wide-blade steel tape, which mitigates sagging over long stretches, making it ideal for accurately measuring timber. Like all carpenter tools, carpenter tape measures come with some standard features. For instance, professional-grade tapes are marked with imperial and fractional inches for precise measurements and may even include stub spacing markings to save time on commonly used dimensions. The latter is often speculated to be a time-saving measure for builders. In addition to the primary features, carpenter tape measures are built to endure rough and reckless job site handling. Therefore, the casing is reinforced to withstand impact while also bolstering the primary locking mechanism that keeps the tape secure mid measurement. Finally, the use of magnetic tips is common making hands-free work seamless as the tape measure can now be docked to metal surfaces, increasing accuracy in complex measurements.
