Difference Between Height and Length

Key Difference – Height vs Length

Height and length are important measurements that are used to determine the size of an object. Height is the measurement from the base of an object to its top; it measures how tall something is. Length is the measurement of the longest side of an object; it measures how long something is. Thekey differencebetween height and length is the fact thatheight is a vertical measurement whereas length is a horizontal measurement.

What is Height?

Height can be defined as the measurement of someone or something from head to foot or from base to top. It is a measure of a vertical distance. In other words, height measures how tall something is or how high up it is. It measures the distance from the base to the top of an object. Height is a measurement that is also used with humans. In humans, the height describes how tall a person is. We also use this measurement to see how tall trees, buildings, and monuments are.

But, the height of some objects can also describe how high something is from the standard ground level. For example, it can describe how high a mountain top is from the sea level, but this height is often calledaltitude.

What is Length?

Length is the measurement or extent of the longest side of an object. It describes how long an object is. In mathematics, the term length can be used to describe the size of a one-dimensional, two-dimensional or three-dimensional object. The length is the only measurement of one-dimensional objects. The measurement of the longest side two-dimensional object can be defined as the length. The short side is known aswidth or breadth. In three-dimensional objects, length is the longest horizontal side of the object.

However, if you change the position of an object, these measurements can change; height can become the length and vice versa. The following image will help you to understand the difference between height, length, and breadth.
