Bay Window vs. Bow Window

Bay and bow windows can transform a room by adding space and natural light — along with bench seating, storage, and a beautiful exterior look. Both options extend outward from a wall and feature multiple window panes connected at angles.

Bay vs. Bow Window

The main difference between a bay window and bow window: the shape. Bay windows consist of three parts with a flat center window that is typically larger than the two side windows. Bow windows use four or more windows to create a look with curvature.

A bay or bow window can enhance the pleasure of being at home, and may also increase property value. Rooms grow larger and feel even more spacious. Light flows in from more angles.

Homeowners can enjoy incredible returns when choosing a bay or bow window for new construction or window replacement.

Benefits of a Bay Window

Bay windows enlarge a room’s open space by extending out even further than a bow window. Bay windows let in more light than flat windows, but typically less than bow windows.

Esthetically, bay windows have a classic look that suits a wide variety of architecture. Victorian and other traditional styles work particularly well with bay windows.

Considerations: The large center panel of a bay window is typically fixed, making them less beneficial for ventilation. Roof and wall remodeling can add to the cost and complexity of adding bay windows.

Benefits of a Bow Window

Bow windows let in the most light possible and create outdoor views from a variety of angles. You can choose sliding or casement windows for some or all of the individual windows to maximize ventilation. Compared to bay windows, bow windows tend to work better for wider, larger window projects.

Bow windows create a beautiful curved effect that works well for both walls and corners. Both modern and traditional homes of various architectural styles can incorporate a bow window with a wonderful impact on esthetics and curb appeal.

Considerations: As with bay windows, a bow window requires construction to extend walls and roofing. Because bow windows have more glass and often custom woodwork, the costs can be a bit higher. Enhanced property value often returns the investment, however. Finally, a bow window may not be suitable for small spaces — you need width of at least six feet or so.
