Which measurement is represented by the term 'width'?

The term 'width' typically refers to the measurement that describes the extent of an object from side to side. In the context of dimensional measurements, width is most closely associated with length, as it effectively captures the horizontal span of a two-dimensional object.

While height denotes the vertical measurement and depth refers to how deep an object is (or the extent of it from the front to the back), thickness usually relates to the measure of how thick something is from one surface to the opposite surface. Hence, associating width with length is accurate as both concepts deal with extending in a similar horizontal direction, making length the most fitting representation in this case.
