Definition
A dimension is a measurable aspect of something, such as its length, width, height, or overall size.
A dimension is a way to measure or describe the size of an object, often in terms of length, width, and height. It can also mean an important feature or aspect of a situation, idea, or problem. In geometry and science, it may refer to the number of directions needed to describe a space, such as two-dimensional or three-dimensional space.
