# Length vs. Height: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on November 30, 2023
Length measures the extent of something from end to end along the longest side, while height is the measurement from base to top or head to foot vertically.

## Key Differences

Length is a measurement that extends horizontally, representing the distance from one end to the other of an object. However, height measures vertically, capturing the distance from the base to the top of an object or figure.
Length is commonly used to describe objects like roads, ribbons, or rivers, emphasizing their extent in a horizontal plane. While, height is often referenced when discussing buildings, trees, or people, focusing on vertical extension.
Length is measured in units like meters, feet, or inches, typically using tools like rulers or measuring tapes along the horizontal axis. Height is also measured in similar units but requires a vertical alignment, often using tools like altimeters or height gauges.
In diagrams or blueprints, length is usually depicted as the horizontal dimension of an object, while height is shown as the vertical dimension, indicating elevation or stature.
Length is observed along the surface of an object, often perceived in relation to how long something is. Height is perceived as how tall or high something stands, often noticeable in the vertical space it occupies.
