If an object has multiple distances to be measured (like a rectangle for example), then length is taken to be the longest of the measurements (as opposed to the width, in the case of the rectangle). Before babies learn to walk, they are measured for length, but once they begin to stand reliably the same measurement changes names, and become height. |
