Bay Window vs Bow Window: Pros and Cons

When homeowners compare a bay window to a bow window, they are usually deciding between a stronger architectural statement and a gentler curve that spreads light across a wider wall.

A bay window projects more sharply and tends to create a usable nook inside the room, while a bow window curves outward in a softer arc and usually brings in a broader sweep of daylight.
