Length
In general English usage, length (symbols: l, L) is one particular instance of distance: an object's length is its extent along its longest dimension. This is to be contrasted with height, denoting vertical extent, and width (or breadth), denoting a lateral extent along a dimension shorter than an object's length. In the physical sciences and engineering, the word "length" is typically used synonymously with "distance".
