Difference between Length and Height

The key difference between length and height is that length is a measurement of the longest dimension of an object in the plane of its existence, while height is the measurement of an object from its base to its top, perpendicular to the plane of its existence.

Length Vs Height

Length	Height
The measurement of an object from one point to another	Height measures an object from the top to bottom
It is measured in the most-extended dimension	It measures in the dimension that would be up in any orientation
It is a measurement on the horizontal axis	It is a measurement on the vertical axis
The length determines how long an object is	Height determines how high the object takes base as a reference
It can be a one, two or three-dimensional objects	It is usually measured for 3-dimensional objects
Line, square, rectangle, cube, etc.	Cube, cylinder, etc.

Difference between Length and Height

Actual Meaning:

• Length is the measurement of an object from one point to another.
• Height measures an object from top to bottom.

Dimension:

• Length is measured in the most-extended dimension.
• Height is measured in the dimension that would be up in any orientation.

Axis of measurement:

• Length is a measurement on the horizontal axis.
• Height is a measurement on the vertical axis.

Used for:

• The length determines how long an object is.
• Height determines how high the object takes base as a reference.

Type of object:

• Length can be measured for one, two, or three-dimensional objects.
• Height is usually measured for 3-dimensional objects.

Examples:

• Length: Line, square, rectangle, cube, etc.
• Height: Cube, cylinder, etc.
