Size

Size refers to the concept of things, usually physical objects, having measurements that are relatively greater or lesser than other things along certain dimensions in physical space, such as length, width, height, diameter, perimeter, area, volume, or mass. In mathematical terms, "[s]ize is a concept abstracted from the process of measuring by comparing a longer to a shorter". Size is determined by the process of comparing or measuring objects, which results in the determination of the magnitude of a quantity, such as length or mass, relative to a unit of measurement. Such a magnitude is usually expressed as a numerical value of units on a previously established scale, such as meters or inches.
