Length vs. Height

Main Difference

The main difference between Length and Height is that the Length is a measured dimension of an object and Height is a distance between the lowest end and highest end of an object.

• Length

  In geometric measurements, length is the most extended dimension of an object. In the International System of Quantities, length is any quantity with dimension distance. In other contexts, length is a measured dimension of an object. Length may be distinguished from height, which is vertical extent, and width or breadth, which are the distance from side to side, measuring across the object at right angles to the length. For example, it is possible to cut a length of wire shorter than the wire’s width. In most systems of measurement, the unit of length is a base unit, from which other units are derived.

  Length is a measure of one dimension, whereas area is a measure of two dimensions (length squared) and volume is a measure of three dimensions (length cubed).

• Height

  Height is the measure of vertical distance, either how “tall” something or someone is, or how “high” the position is.

  For example, “The height of that building is 50 m” or “The height of an airplane is about 10,000 m”.

  When the term is used to describe how high something like an airplane or a mountain peak is from sea level, height is more often called altitude.In a cartesian space, height is measured along the vertical axis (y) between a specific point and another that does not have the same y-value. If both points happen to have the same y-value, then their relative height equals to zero.
