About Tape Measures
Tape measures consists of narrow strips of cloth, paper, plastic, vinyl, fiberglass or metal marked with units of measurement, such as inches or centimeters, as well as increments in between. Since tape measures are typically longer and more flexible than rulers, they can be used for measuring longer distances or rounded objects. Does this Spark an idea?

Type
-
Tape measures designed for use in carpentry and construction are typically made of metal, sometimes with a nylon or polyester film coating for added durability. These often come rolled in a plastic or metal case and can be extended or retracted. Tape measures designed for sewing and tailoring are usually simple measurement strips made from vinyl or fiberglass. This makes them ideal for measuring curves and parts of the body, as well as fabric lengths.
Features
-
Some tape measures are marked only in inches or centimeters, while sewing tape measures often have inches on one side and centimeters on the other. Many tape measures also have markings for significant measurements. For example, carpentry tape measures often have a black arrow every 12 inches, and a red square every 16 inches for use in measuring while framing. Some include a black diamond every 19.2 inches for alternate-framing measurements. Many sewing tape measures offer yardage markings for common fabric lengths.

Benefits
-
Carpentry tape measures often have a small metal bracket at the tip. This allows the end to be hooked over the edge of a board or other surface while measureing a long distance. Although some carpentry tape measures include a manual crank on the case for extending and retracting the tape measure, others automatically retract with the touch of a button or lever. Many cases also have a belt clip.
Size
-
Tape measures come in various widths, from about five-eighths of an inch to 11/4 inches wide. Wider tape measures may be easier to read, since they have room for larger numbers. Carpentry tape measures come in various lengths, ranging from about 12 feet to 35 feet. The casing for most carpentry tape measures about 3 to 4 1/2 inches square, although some novelty tape measures are small enough to fit on a key chain. Sewing tape measures are typically 60 inches long, but also come in other lengths.
Risk Factors
-
Tape measures that retract automatically may move very quickly and cut the skin. Some, though, offer a locking mechanism to prevent this from happening. Proper use canalso help prevent injuries.
