Window Shopping: How to Pick the Right Window Size

The style and material of your new windows is mostly a matter of preference. To find the right window style, homeowners just need to narrow down their preferences. Finding the right window size, however, is trickier since it’s a lot more technical. No need to worry, though; as the local window contractors from Renewal by Andersen® of San Antonio offer some tips below.File.jpg

Large vs. Small Windows

When it comes to windows, bigger isn’t necessarily better. The size of your windows should be based on which side of your home they’ll be installed. For instance, the south side of your home is the best place to install large windows, since it’s the side that receives the largest amount of sunlight throughout the year. Just make sure the windows you choose have a low solar heat gain coefficient to keep your interior from becoming too hot in the summer.

Meanwhile, most contractors would recommend installing small energy-efficient replacement windows on the west side of your house, since it bears the brunt of the afternoon heat. Always look for the ENERGY STAR® label and check which climate zone the window is certified in (usually found to the right of the label) before making a purchase.

Check Local Building Codes 

Don’t forget to check your local building codes for any restrictions on the size and placement of your windows. For instance, egress windows in the basement should be big enough to double as an emergency exit.

Customization: The Only Way to Get a Perfect Fit

Keep in mind that most brands manufacture their windows according to standard sizes, so there are no guarantees that windows bought off the shelf will be the right fit for your home. The only way to ensure your new windows will fit perfectly is to customize them.
