What are Bay Windows?

A bay window isn't actually a window. It's three windows, joined together to form a solid unit. Bay windows are set at angles that protrude out from the main walls of the house, creating a small area—referred to as a bay—that actually adds physical space to the structure. 

Bay windows and the space they create can be almost any size, and have multiple uses. In some cases they can extend from floor to ceiling, and be large enough to accommodate a table and chairs, almost like a small sitting room. They could also be much smaller, creating a cozy nook with an extended shelf-like sill.

Most bay windows are arranged at 30, 40, or 60 degree angles. There's typically a close correlation↗ between this angle and the  window's depth. Depending on the size of the windows, it usually works out like this:

  • 30-degree bay windows range from about 12 to 14 inches deep.
  • 45-degree bay windows are usually 16 to 22 inches deep.
  • 60-degree bays windows are tend to be 18 to 24 inches deep. 

Pros and Cons of Bay Windows

As with any style of windows, there are advantages and disadvantages of bay windows for your home. While they don't always go with every architectural style, they have numerous benefits, so it's always important to carefully consider the pros as well as the cons. 

Pro: Add Space to Your Home

In very real terms, the three-dimensionality of bay windows allows them to literally add physical space to your home. You can play with how you use that space in all kinds of ways. But just as importantly, by creating an expansive view bay windows make your space "feel" bigger, and can make a small room feel more open.

Pro: Great Natural Light

Having bay windows put in will allow much more natural light into your home, and do so without compromising comfort. Today's bay windows have advanced energy efficiency, and most have functional side windows that you can open for air flow. 

Pro: Add to Your Curb Appeal

Bay windows are among the few window styles that actually alter the exterior profile of your home. They have a real impact on your curb appeal, and can be a significant selling point if you're planning on eventually selling your home.

Con: More Expensive than Other Windows

It's true that you'll pay more for bay windows than for traditional single-hung or double-hung windows. Of course, that makes sense when you think about it. A bay window is actually three windows, and many are large enough to add significant space to the room they're in.

Con: Must Be Installed by a Professional

Bay windows can develop structural issues over time if they are not installed properly. For that reason, this is the type of window installation that should be left to a trained professional and not DIY-ed.

Who Sells Bay Windows?

Most of today's leading window makers include bay windows in their lineup. Bay window brands include: 

Bay windows offer an opportunity to add light and elegance to your living space. If you're ready to replace the windows in your home consider the architecture in your home and ask yourself a few questions:

  • Would a bay window look appropriate in this style of house?
  • Does a bay window make sense in this space?
  • Does a bay window or a regular flat window make more sense?
    • Is the cost of a conversion (bay to flat, flat to bay) worth it?
