When deciding on the size of a replacement bay window, it is important to consider what the window will be used for, and the size of the room that it is going in. Due to the size of many bay windows, not every room in your home will work for a bay or bow window installation. Some sections of the wall may need to be reinforced more than others, because they bear more weight from the house. A large bay window often increases your home’s value quite a bit, making it a great window installation project. See a list of standard sized windows to understand how a bay window compares in stature for a room.

Choosing Bay Windows
An Enhanced View
Bay windows are known for making the most of a beautiful view. While most windows are stuck inside the walls of a home, bay windows stretch out and around those boundaries. This means that you can take a look at the view out and around the sides of your home. You will be able to see in more directions and bring a lot of natural light into your space.
Increased Floor Space
When you have a compact home and you’re looking for ways to increase the floor space, bay windows are one of the options you have available to you. Most bay windows will create a shelf that you can use for added storage, but some are designed to go right down to the floor of the room. These windows actually increase the floor space that you have in the room. They can add ten or more square feet to a room, and if you are dealing with tight living arrangements, the added space can make a big difference.
More Natural Light
Bay windows are known for bringing in a healthy dose of sunlight. By opening up the space with a bay window, you allow natural light to enter your home from several different directions at the same time. However, you will want to invest in higher efficiency windows to reduce the solar heat gain, which can ultimately increase costs.
Not Suitable For Every Room
Due to the size of many bay windows, not every room in your home will work for an installation. When installing a bay window, some sections of the wall have to be reinforced more than others, because they bear more weight from the house. If you’re planning on having a bay window installed in your home, you should make sure that a window professional takes a look at your home and chooses a section that will require any significant reinforcement when the window is installed.
They can also block narrow walkways and patios as they extend outwards. Always consider how far out the window is going to extend from the house, and think about any problems the window will cause as a result.
