A tape measure is a device used for measuring distances and lengths. It consists of a long, flexible strip of wood, plastic or metal with graduated markings along its length, representing specific measurements such as inches, centimeters or feet. The user can pull out the tape to extend it and read the measurement by aligning one of the marks on the object being measured with the corresponding mark on the tape. Tape measures come in various lengths and widths depending on their intended use - from small pocket-size models for quick measurements, to longer versions designed for professional or home construction projects.
