Height is the measurement of vertical distance, but has two meanings in common use. It can either indicate how "tall" something is, or how "high up" it is. For example one could say "That is a tall building", or "That airplane is high up in the sky". These can both be referred to as the height of the object, as in "The height of the building is 50 m" or "The height of the airplane is 10,000 m". When used to describe how high something like an airplane or mountain peak is from sea level, height is more often called altitude. Height is measured along the vertical (y) axis between a specified point and another point.

In mathematics

Dimensional models define height as the third dimension, the other two being length and width. If we construct a plane formed by the length and width, and construct a line which intersects that plane at a 90 degree angle, then the height is measured along that line.

Height can also refer to:

1. the altitude of a triangle, which is the length from a vertex of a triangle to the line formed by the opposite side;
2. a measurement in a circular segment of the length from the point of the circular segment farthest from the center, to trc of the segment (see diagram in circular segment).
