People often ask about the "correct" use of length, width, height, and depth. In the most common contexts in elementary school, mathematics does not have a formal definition for these terms, nor does it have rules about "proper" use. But natural usage does follow some conventions.

In some contexts, two of these terms -- length and height -- do also have a specific mathematical meaning. Length, when referring to measurement in one dimension (as in the length of a line segment or a piece of string), has a specialized meaning. So does height when it is used in conjunction with base.
