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

What Sets A Bow Window Apart From A Bay Window

The easiest way to separate the two is to look at the geometry. A bay window usually has three panels, while a bow window uses four or more to create a gentler curve.

The shape influences the room, the exterior line of the house, and even the way sunlight comes in during the day.

A bow window spreads the view across a wider arc, so the outside line looks softer and more rounded.

Some bay and bow configurations use fixed center panes with flanking casement or double-hung windows, while others use different combinations.
