Home Style

Certain home styles and designs work better with bay or bow windows than with others. For example, in classic Colonial or Victorian designs, bow windows can be the perfect choice to score style points. Other times, like ranch-style homes or contemporary Cape Cods, bay windows are more elegant and inviting.


The size of the wall is a crucial aspect to consider. Bay windows work well on large walls, with a minimum of 6.5 feet of room left. It is certainly feasible to purchase bay windows that are smaller in size; however, cramming too many windows into a narrow space will make the space appear cluttered. Smaller walls look more natural when paired with bay windows.

Bay windows may appear at a strange angle if you have very wide windows. The central pane will need to be extremely large to ensure that the window isn’t too far out towards the backyard. If this is the case, the bow’s soft curve is the best choice.


Windows can be more than just a source of sunlight. They also help encourage the flow of air and airflow. They are usually inoperable, so that homeowners may open them for fresh air. There are casement versions that are available on the market. However, the designs aren’t as common.
