Awning Window Sizes

Awning windows are hinged at the top and open outward, allowing for ample ventilation. Though they tend to be a bit smaller in size than other window types, you may be surprised by just how big they can get. In this guide, let’s take a look at everything you need to know about awning window sizes.

Awning Window Sizes

To start, let’s take a look at the standard widths and heights of awning windows offered by most window manufacturers.

• Awning window widths: 2′ to 3’10”
• Awning window heights: 1’8” to 7’9″

It’s important to note that all of these these dimensions refer to the window opening, not the entire window unit including the frame.

Custom Sizes and Shapes

While standard sizes are suitable for many homes, custom options are also available. Custom sizes allow for greater flexibility, especially in unique architectural designs or when replacing windows in older homes with non-standard openings.

Custom-sized awning windows can be manufactured to almost any dimension, ensuring a perfect fit.

Measuring for Awning Windows

Accurate measurement is crucial when selecting awning windows. To measure the space for a new awning window, start by measuring the width and height of the opening in three different places: the top, middle, and bottom for width, and the left, center, and right for height. Use the smallest measurement to ensure the window will fit.

Factors Influencing Size Choices

If you are replacing an existing awning window, then you can simply measure your existing one to see what size you need. But if you’re installing a new one, then you need to decide just what size of awning window you want.

Several factors will influence your awning window size choice.

1. Architectural style. The style of the home can dictate the appropriate size and proportion of awning windows. For instance, modern homes might feature larger windows, while traditional homes might opt for smaller, more discrete ones.
2. Functionality. The room’s purpose impacts the window size. Larger windows might be preferable in living rooms for more natural light, while smaller windows could be more appropriate in bathrooms for privacy.
3. Energy efficiency. Larger windows can provide more natural light, reducing the need for artificial lighting. However, they can also lead to more heat loss or gain, affecting energy efficiency. Homeowners should consider the balance between light and energy performance.
4. Ventilation needs. Awning windows are excellent for ventilation. Larger windows will allow more air to circulate, which can be beneficial in rooms like kitchens or bathrooms.
5. Aesthetic preferences. Ultimately, personal taste plays a significant role. Some homeowners prefer the look of large, expansive windows, while others may opt for smaller, more traditional sizes.

Frame Materials and Impact on Size

Your window frame material choice can also impact the available sizes. Common materials include wood, vinyl, aluminum, and fiberglass. Each material has different structural properties that can influence the maximum and minimum sizes available.

Cost Implications

The size of awning windows directly impacts the cost. As you’d expect, larger awning windows will generally be more expensive due to the increased material and potentially more complex installation requirements.

When budgeting for window replacement or installation, the size will be a significant factor in the overall cost. Check out our guide to awning window cost for more information.

Maintenance and Cleaning

Maintenance requirements may vary based on size. Larger awning windows might be more challenging to clean and maintain, especially if they are hard to reach. Since they will likely see more rain and roof runoff than other window types, you may find yourself needing to clean them more often.

Consider ease of maintenance when choosing the size of your awning windows.
