spatial dimensions
Length, width, height
Spatial dimensions are the independent directions in which physical objects can extend or move—length, width, and height in everyday experience.
Physics sometimes posits additional spatial dimensions beyond the three we perceive: String theory requires ten spatial dimensions.
The term distinguishes extent in space from time, which is sometimes called the fourth dimension.
- widthDistance across something

- lengthMeasure of extent
- planeWinged flying vehicle
