Oblong windows

Oblong windows

Oblong windows are windows that have a rectangular or elongated shape. Usually narrow on one dimension, they can be horizontally oriented or vertically oriented depending on what purpose they need to serve.

Also called clerestory windows, oblong windows are usually placed at the top of a wall, close to the ceiling or roof. The purpose of these windows is primarily to let natural light into a building while also providing a unique architectural element to the facade or interior. You can often find these types of windows in rooms that require additional amount of light, like basement and hobby rooms, and also on top of the entrance door (in this case they are called transom windows).


Narrow vertical windows can be used to create visual interest and add to the overall aesthetic of a home, increase the natural light on small portions of walls or used as a sidelight to main entrance doors.
