    bay window

    Bay Window

    Bay windows feature 3 openings with sharp angles between. They usually extend further out than bow windows, and many people choose to add a unique sitting area in the extra space bay windows provide. The center window is typically fixed with a combination of fixed or operational windows on the ends. Sometimes the end frames are smaller than the center one, changing up the aesthetic slightly.

    Bow Window

    Bow windows, on the other hand, generally consist of 4 to 5 window openings, connected in a more subtle and sweeping curve as opposed to the dramatic angles of bay windows. One of the greatest advantages of bow windows is that you can choose any configuration of fixed or operational window frames to create the perfect look for your space.
