Batter (walls)

Batter in construction is a receding slope of a wall, structure, or earthwork. A wall sloping in the opposite direction is said to overhang. The term is used with buildings and non-building structures to identify when a wall is intentionally built with an inward slope. A battered corner is an architectural feature using batters. A batter is sometimes used in foundations, retaining walls, dry stone walls, dams, lighthouses, and fortifications.

The batter angle is typically described as a ratio of the offset and height or a degree angle.
