Bay window



A bay window is a window space projecting outward from the main walls of a building and forming a bay in a room.

Bay window is a generic term for all protruding window constructions, regardless of height. The most common inside angles are 90, 135 and 150 degrees, though triangular bays formed of two windows set at 120 degrees may be found.

Most are polygonal or square; when curved they are called bow windows.

A bay window with a flat front and angled sides is called canted.

A bay window supported by a corbel, bracket or similar is called an oriel window.
