![]() ![]() Furthermore, a hand crank one features a looking-like-ring hook where the true zero points begin. So, preferable action is needed whenever it’s wet or exposed to high temperate. Despite a hand-crank type comes with the case, it does not totally cover the entire blade. In other words, it’s not designed with curved shape just flat and flexible. Aside from that, the blade is fairly contrasting to the retractable ones. So you need to retract the blade by your hands through the crank. It utilizes a hand-crank method to roll up the blade. Unlike the retractable, a hand-crank type uses no spring mechanism to coil the blade. ![]() Workers such as trades, carpenters, woodworkers, electricians, builders, contractors, surveyors, and etc use a tape measure and they might have at least one tape measure in their toolbox. Many people rely on this tool to fulfill their measurement needs. Its curved shape helps the blade stand out while extending. Moreover, it has a unique-looking blade that is different from the sewing and hand-crank type ones. Also, it comes with a hard case where the spring is stored and protected. Retractable Tape Measure Retractable Tape MeasureĪ retractable tape measure is a distance measuring tool that typically features a spring mechanism to recoil the blade so that it’s compact and portable to carry up. ![]() You could also use this to measure the diameter of some parts of your body such as hand, head, chest, and so forth. It uses no retraction system you need to coil it with your hands.Īs its name, most tailors use this for sewing purposes. Also, it generally comes with no hard case. If we convert it to the imperial unit, it’s roughly no more than 4 feet. In most cases, the maximum length of a sewing tape measure is 100 centimeters (1 m). Sewing Tape Measure sewing tape measureĪ fabric tape measure is a short-range ruler that is flexible and most commonly used for sewing. The retraction system, which is the system to coil up the blade, also divides based on its existence. The case, which is the house of the coiled blade, affect the classification based on its existence. The true-zero-tab, where the first point of measurement begins, divides based on its shape. The blade, where you can find the graduations, divides based on its length. We can classify them into 3 groups based on their body parts: fabric tape measure, retractable tape measure, and hand-crank tape measure.Īs general, there are four major body pieces of a tape measure: blade, true-zero tab, case, and retraction system. The case is very useful to store the rolled-up blade and strongly protectable to secure the content from impact and other unexpected damage. Lastly, tape measures come with the case while the ruler doesn’t. ![]() As they become compact, you can easily carry it up anywhere you want. You can easily turn the long blade into a coiled-up shape and save it into the case. Thirdly, it features a retraction system except for the sewing tape measure type. Surely, this capability is very determinable especially when we are going to measure a longer object. Secondly, based on one of its variants, it is able to measure until 300 feet in maximum, while a ruler is only 1 meter or 3.3 feet in maximum by comparison. Some are made of fabric, nylon, ribbon, and even metal strip. Moreover, this kind of property comes from the material that constructs it. Therefore, the problem that comes from a typical long measuring ruler, which is very rigid then consequently cannot be coiled up and pretty hassling to carry up, can be solved. The easiest way to observe it is by comparing it to a ruler.įirstly, its blade is flexible, bendable, and rollable. However, there are some stick-out differences that we can observe. Generally, a tape measure is similar to a ruler, in which the way we use it is by laying it on object being measure such as wall, floor, etc. Depending on the type of tape measure, it can serve the measurement length differently. A tape measure is a tool to measure length. ![]()
