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

The Basic Shape Tells You A Lot

Bow windows and bay windows often get lumped together, but the shape difference is real, and it affects look, structure, cost, and even the way the room feels.

A bay window usually has three panels, with a large center unit flanked by two angled side units.

A bow window, by contrast, uses four or more equal-sized panels arranged in a gentle curve.

Once you know what to look for, the difference is obvious. Bays read as angular and architectural, while bows look softer and more continuous.
