What Is The Difference Between A Bay Window & Bow Window?

Bay windows

  • Consists of three glass panels, with a larger central window and two smaller windows on either side. The centre pane is often considered the “picture window”.
  • Bay windows extend outwards at a 25 to 45-degree angle.
  • This type of window frame generally protrudes less than bow windows but offers a significant amount of interior floor space.

Bow windows

  • Bow windows are generally made up of four or five identical windows, creating a curved or “bow” appearance.
  • They’re fitted at a 10-degree angle, sweeping away from the wall in a graceful arch.
  • Bow windows create a rounded or semi-circular exterior appearance due to the multiple glass panels.
  • These windows bring in more light and extend living areas better than bay windows due to their curved design.

As mentioned, bay and bow windows come in various styles and frames.
