Bay Windows vs. Bow Windows: Which Is Right for Your Home?

The Core Differences Between Bay Windows And Bow Windows

Bay windows and bow windows both project outward from the wall, but they are built differently and they change a room in different ways.

Bow windows are built from several narrower units, which gives the exterior a subtle arc rather than a faceted shape.

The shape is not just cosmetic.

The right choice depends less on the catalog photo and more on the wall, the roofline above it, and how you plan to live with the space.

Where Each Style Works Best
