When it comes to choosing windows that blend function, durability, and aesthetic appeal, Andersen casement windows are a popular choice among homeowners and builders. Known for their clean lines, ease of operation, and energy efficiency, Andersen casement windows are available in a wide range of sizes to suit different architectural needs. Whether you’re installing a single window in a small room or creating a panoramic view with multiple units, understanding Andersen casement window sizes can help you plan and execute your project with greater precision. This topic explores standard and custom sizes, configuration options, and tips to choose the best fit for your space.
What Are Casement Windows?
Design and Functionality
Casement windows are hinged on the side and open outward like a door, typically operated with a crank handle. They are ideal for maximizing ventilation and providing unobstructed views. Because the sash closes tightly against the frame, casement windows offer excellent energy efficiency and weather resistance.
Why Choose Andersen Casement Windows?
Andersen is a trusted name in the window industry, offering high-quality products that combine innovative design with reliable performance. Andersen casement windows are part of several product lines, including the 100 Series, 400 Series, A-Series, and E-Series. Each line offers a variety of sizes, finishes, and custom options to meet different project goals and budgets.
Standard Andersen Casement Window Sizes
Common Widths and Heights
Standard casement window sizes by Andersen typically range from 17 inches to 41 inches in width and 23 inches to 85 inches in height. These dimensions refer to the rough opening the space in the wall where the window will be installed.
- Width: 17′, 20′, 24′, 28′, 32′, 36′, 40′, 41′
- Height: 23′, 29′, 35′, 47′, 59′, 71′, 85′
These measurements vary slightly depending on the series. For example, the 400 Series has a slightly different sizing chart than the 100 Series. Always consult the official size chart for the specific series you’re interested in.
Size Codes
Andersen uses a coding system to identify standard window sizes. Each code refers to the width and height of the unit in feet and inches. For example:
- CW25: 2 feet wide by 5 feet high
- CW3048: 3 feet wide by 4 feet 8 inches high
- CW2856: 2 feet 8 inches wide by 5 feet 6 inches high
This system makes it easier to specify window dimensions during the ordering process and ensure compatibility with architectural plans.

Keep in mind that custom sizes may increase the cost and production time, so it’s important to plan ahead.
Tips for Choosing the Right Andersen Casement Window Size
Measure Carefully
Accurate measurements are essential. Measure the rough opening, not the existing window, and consult a professional installer or contractor if needed. Be sure to allow for the manufacturer’s recommended tolerances.
Match the Room Function
Smaller windows work well in bathrooms or utility rooms, while larger casement windows are better suited for living rooms, kitchens, and master bedrooms. Consider natural light, ventilation needs, and privacy when selecting window size.
Balance with Architectural Style
Choose sizes that complement your home’s overall design. Oversized windows might look out of place on a traditional cottage but can be stunning in a modern home. Symmetry and proportion are key factors.
Combine Units for Impact
If a single casement window doesn’t provide the desired effect, combine two or three windows side by side. Andersen offers configurations such as:
- Twins (two casement windows joined together)
- Triples (three in a row)
- Casement with fixed picture window in center
This approach enhances views and creates architectural interest while still using standard-size components.
Energy Efficiency and Glass Options
Choose the Right Glass
Window size affects energy efficiency. Larger windows allow more heat gain and loss, so it’s important to select energy-efficient glass. Andersen casement windows are available with options like Low-E glass, SmartSun, and double or triple pane designs for improved insulation.
Climate Considerations
In colder climates, choose windows with high thermal resistance. In hot regions, opt for glass that reduces solar heat gain. The size of the window should work with these performance needs to maintain comfort and lower energy bills.
Andersen casement window sizes are designed to accommodate a wide range of building needs, from compact utility windows to expansive floor-to-ceiling designs. Whether you’re remodeling or building new, understanding the available standard and custom size options across Andersen’s product lines can help you make an informed choice. Measure carefully, match your style, and consider combining units for more dramatic effects. With the right size and configuration, Andersen casement windows can enhance the beauty, comfort, and efficiency of any home.
