H. A. Farrand with Farrand Rapid Rule

Tape measure is a flexible ruler used to measure size or distance. It consists of a ribbon of cloth, plastic, fibre glass, or metal strip with linear-measurement markings. It is a common measuring tool. Its design allows for a measure of great length to be easily carried in pocket or toolkit and permits one to measure around curves or corners. Today, measuring tapes made for sewing are made of fiberglass, which does not tear or stretch as easily. Measuring tapes designed for carpentry or construction may use a stiff, curved metallic ribbon that can remain stiff and straight when extended but retracts into a coil for convenient storage. This type is called a tape measure. The self-marking tape measure allows the user to make marks on the tape, eliminating the need for a pencil or chalk.

History

The tape measure was invented in 1829 in Sheffield, England by James Chesterman. Originally this device was intended for tailoring purposes and was a significant improvement over the rigid rulers then in use. It was not until 1868 that Alvin J. Fellows of New Haven, Connecticut, received a patent for his improvement of the tape measure that included a spring click mechanism.

Types

There are several types of tape measures that cater to different professions and uses. These include:

• Sewing tape measure: Made of soft cloth or plastic, this type is used by tailors and dressmakers for body measurements, fabric, and other craft uses.
• Surveyor's tape measure: Often made of a stiff metallic ribbon and used in land surveying. It can extend tens of meters or more and is designed for precision and durability.
• Construction tape measure: Typically encased in a rugged plastic or metal case, these are used in construction and carpentry for measuring distances and materials.
• Diameter tape measure: A specialized tape measure used to measure the diameter of a pipe or other round object.

Features

Modern tape measures may also have additional features designed to make measurements easier and more accurate, such as:

• Locking mechanisms to hold the tape extended
• Magnetic hooks to attach the tape to metal objects for easy measurement
• Belt clips for easy carrying
• Double-sided printing for readability from any angle
• Digital readouts for precise measurements

Usage

To use a tape measure, extend the tape to the desired length and read the measurement where the tape meets the object being measured. For accurate measurements, ensure the tape measure is straight and level. When measuring inside corners or spaces, the metal or plastic end hook can be used to catch onto edges, allowing for more accurate measurements.

Maintenance

Proper maintenance of a tape measure is essential for its longevity and accuracy. It should be kept clean, dry, and stored in a cool, dry place to prevent damage. The metal tape should be wiped down after use to remove any debris or moisture that could cause rust or corrosion.
