Choosing the perfect windows can be quite a challenge as these usually come in a range of styles. As building processes and technologies have evolved, the need for larger-sized windows has also grown significantly, making vast expanses of glass a standard for many households. However, don’t forget that getting the right sizes for your windows is also important.
The size of your windows can affect the overall energy efficiency, comfort and appeal of your property. Here are tips to help you determine the ideal window size for your home.
Things To Consider When Selecting Window Size
Most windows come in conventional sizes, simplifying the selection and installation processes for homeowners. Standard windows usually have a width of 24 to 48 inches and a height of 36 to 72 inches. However, there may be areas in your property that don’t fit these dimensions. They will impact the cost of your window installation, so getting accurate measurements is vital.
Thermal Mass and Window Size
Thermal mass refers to a material’s ability to absorb heat energy. A large amount of heat energy is required to modify the temperature of high-density materials, such as bricks and concrete. Take note that the right balance of thermal mass in your home can do wonders for your comfort and energy costs.
Windows with more glass are better suited for dwellings with higher thermal mass and large north-facing windows. They should be avoided in residences with low thermal mass. Choose energy-efficient windows that suit your space and local climate so you won’t have to worry about reduced window performance.
The general rule is to keep the total glass area between 20% and 30% of the total floor area. However, if you have east-facing and south-facing windows, their size should not exceed 15% of the room’s total floor area. Meanwhile, the size of north-facing windows can go up to 15% to 25% of the room’s total floor area depending on floor material and access to sunlight. West-facing windows should have a size that’s less than 10% of the room floor area.
Standard Sizes of Each Window Style
An awning window is often a go-to choice as it is easy to operate and can be opened even during light rain. Furthermore, because they are hinged at the top and expand outward, they provide plenty of ventilation.
The width of an awning window ranges from 2 feet to 3 feet 10 inches, and its standard height ranges from 1 foot 8 inches to 7 feet 8 inches.
Bay windows are a great choice for expanding your space, adding architectural appeal and capturing more light and beauty. Installing a bay window instantly makes an area feel more spacious, so it’s a worthwhile investment for homeowners.
The width of standard bay windows ranges from 3 feet 6 inches to 10 feet 6 inches, and the height of a bay window ranges from 3 feet to 6 feet 6 inches. If you want something bigger, custom sizes are available for bay windows, which come at an extra cost.
Hinged windows are excellent for warm locations that need natural ventilation and comfort throughout the year.
The width of casement windows varies from 1 foot 2 inches to 2 feet 11.5 inches, and their height ranges from 2 feet 5.5 inches to 6 feet 5.5 inches.
Among all window styles, double-hung windows are the most common type of replacement windows in the U.S. They are often used in bedrooms and kitchens. They usually come in a wide range of sizes to accommodate rough openings.
A double-hung window’s width can be anywhere from 24 to 48 inches while its height can range from 36 to 72 inches.
If you need more natural light coming into your home, picture windows would be ideal. These windows cannot be opened, and they are commonly used in living rooms and kitchens. If you’re keen on installing this type of window, you have the liberty to go with either a smaller or larger size. However, make sure to consider the space where you will be installing it.
The most common width for picture windows is two feet, three feet, four feet, six feet and eight feet. Meanwhile, standard picture window height can range from 1 foot to 8 feet.
Often installed in bathrooms and bedrooms, slider windows are designed to be wider than tall. If your window dimensions fall within this range, you can replace it with a normal sliding glass window without changing the rough opening.
The width of a sliding window can be 36 inches, 48 inches, 60 inches, 72 inches or 84 inches. Meanwhile, its height can be 24 inches, 36 inches, 48 inches or 60 inches.
How Will I Know the Window Size I Need?
The size of a window is usually indicated by a combination of its width and height. The first two numbers represent width while the second two represent height. For example, a 2426 replacement window is 2 feet 4 inches wide and 2 feet 6 inches tall. Take note, however, that the window’s dimensions may be ½ inch smaller than the whole number identifier.
