Bay Window vs. Bow Window: What’s the Difference?

How To Tell Them Apart At A Glance

Bay windows usually make a room feel more dramatic and defined. They create a stronger alcove, which works well for a bench, reading nook, or a built-in display area.

In tighter rooms, the footprint matters. A bay window may eat into the space in one noticeable chunk, while a bow window spreads its projection across a wider curve.
