Height

[1] Furthermore, if the point is attached to the Earth (e.g., a mountain peak), then altitude (height above sea level) is called elevation.

[2] In a two-dimensional Cartesian space, height is measured along the vertical axis (y) between a specific point and another that does not have the same y-value.

In the case of three-dimensional space, height is measured along the vertical z axis, describing a distance from (or "above") the x-y plane.

The English-language word high is derived from Old English hēah, ultimately from Proto-Germanic *xauxa-z, from a PIE base *keuk-.

The derived noun height, also the obsolete forms heighth and highth, is from Old English híehþo, later héahþu, as it were from Proto-Germanic *xaux-iþa.

In human populations, average height can distill down complex data about the group's birth, upbringing, social class, diet, and health care system.
