Width refers to the measurement of an object from one side to the other, typically perpendicular to its length. It is a key dimension used in various fields, such as architecture, engineering, and design, to determine how much space an object occupies. For example, the width of a table can influence how many people can comfortably sit around it. In everyday life, width is often used to describe the size of items like doors, roads, and furniture. Understanding width helps in making decisions about fitting objects into spaces, ensuring that they are practical and functional for their intended use.
