Tape Measure Types: 3 Types You Should Know

Generally, a tape measure is similar to a ruler, in which the way we use it is by sticking it on something we are measuring. However, there are some stick-out differences that we can observe.

Tape Measure Vs. Ruler

The easiest way to observe it is by comparing it to a ruler.

Firstly, its blade is flexible, bendable, and rollable. 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. Moreover, this kind of property comes from the material that constructs it. Some are made of fabric, nylon, ribbon, and even metal strip.

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. Surely, this capability is very determinable especially when we are going to measure a longer object.

Thirdly, it features a retraction system except for sewing tape measure type. You can easily turn the long blade into a coiled-up shape and save it into the case. As they become compact, you can easily carry it up anywhere you want.

Lastly, tape measures come with the case while the ruler doesn’t. The case is very useful to store the rolled-up blade and strongly protectable to secure the content from impact and other unexpected damage.

Tape Measure Classifications

We can classify them into 3 groups based on its body parts: fabric tape measure, retractable tape measure, and hand-crank tape measure.

As general, there are four major body pieces of a tape measure: blade, true-zero tab, case, and retraction system. The blade, where you can find the graduations, divides based on its length. The true-zero-tab, where the first point of measurement begins, divides based on its shape. The case, which is the house of the coiled blade, affect the classification based on its existence. The retraction system, which is the system to coil up the blade, also divides based on its existence.

Sewing Tape Measure

A fabric tape measure is a short-range ruler that is flexible and most commonly used for sewing. In most cases, the maximum length of a sewing tape measure is 100 centimeter / 1 meter. If we convert it to imperial unit, it’s roughly no more than 4 feet. Also, it generally comes with no hard case. Its true zero point is a metal tab. It uses no retraction system; you need to coil it with your hands.

As its name, most tailors use this for sewing purpose. You could also use this to measure the diameter of some parts of your body such as hand, head, chest, and so forth.

Retractable Tape Measure

A 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. Also, it comes with a hard case where the spring is stored and protected. Moreover, it has a unique-looking blade which is different from the sewing and hand-crank type ones. Its curved shape helps the blade stand out while extending.

Many people rely on this tool to fulfill their measurement need. Workers such as trades, carpenters, electricians, builders, contractors, surveyors, and etc use tape measure and they might have at least one tape measure in their toolbox.

Hand-crank Tape Measure

Unlike the retractable, a hand-crank type uses no spring mechanism to coil the blade. It utilizes a hand-crank method to roll up the blade. So you need to retract the blade by your hands through the crank. Aside from that, the blade is fairly contrasting to the retractable ones. In other words, it’s not designed with curved shape; just flat and flexible. Despite a hand-crank type comes with case, it does not totally cover the entire blade. So, preferable action is needed whenever it’s wet or exposed to high temperate. Furthermore, a hand crank one features looking-like-ring hook where the true zero point begins.

We generally use hand-crank measuring tapes for far distance measurement. Therefore, a hand-crank type is typically suitable for surveyors, etc.

Overall

In some cases, a ruler is a good option for shorter measurement. It’s also more corrosion resistant. Certainly, it’s easier to draw a rectangle using it than using a measuring tape. Whereas, a tape measure is an undeniable option for longer measurement. It will be very easy and accurate to measure the length of a table using it rather than a ruler. Overall, any linear measuring tool has specific benefits and drawbacks. Therefore, it’s important to suit the tools with needs.
