Height vs. Altitude: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Updated on November 6, 2023
Height refers to the distance vertically from a base level to a point, while altitude is specifically the vertical distance above a reference point, usually the Earth's surface.

Key Differences

Height is generally used to describe how tall something or someone is, often measured from bottom to top. Altitude, on the other hand, is a specific term used to denote the elevation or distance above a certain reference point, particularly above sea level or ground level.

Height can be used to describe the stature of a person, the extent of an object, or the peak of a structure. It's a versatile term in everyday contexts. Altitude is a more specialized term, often used in aviation, geography, and other scientific fields to express the vertical distance from the Earth's surface.

When talking about the height of a building, one refers to how tall the building is from its base to its top. Discussing the altitude of an aircraft, it means the measurement of the aircraft’s position relative to sea level or the ground below.

Height is also used in mathematics and geometry to express the distance from the base to the top of a figure or shape. Altitude still holds its specific meaning in these contexts, often relating to measurements above a standard datum point in various applications.

The term height can also be metaphorical, referring to the peak or zenith of an abstract concept, such as "the height of fame." Altitude does not typically carry a metaphorical use and remains a measure of physical vertical distance in relation to the Earth's surface.
