The long wall short wall methods are used to estimate the quantity of different work. In this method, the longer walls in a building (generally in one direction) are considered as long walls and measured from out to out and the shorter walls in a perpendicular direction to the long walls are considered as short walls and are measured from in- to-in for a particular layer of work.

These lengths of long and short walls are multiplied separately by the breadth and height of the corresponding layer and are added to get the quantity. Such length of long and short walls varies in every layer of footing.
