Garden window sizes can vary and include several components. Garden window standard sizes have a wide range, with the most common units measuring anywhere from 36 by 36 inches to 72 by 60 inches. Understanding these dimensions is useful for homeowners in Maryland, Virginia, and throughout the Mid-Atlantic region planning a kitchen window replacement or looking to add more natural light to their homes.
Choosing the right size for a garden window can be tricky. Read on to learn more about garden window sizes and how the industry standard measures up.
What Are Garden Windows?
Garden windows project outward from your home and let in natural light from four different angles. Filled with potted flowers and herbs, a garden window is a great way to add natural beauty to your space. They’re fitted with specially insulated glass to create a favorable environment for plants to grow, even in colder months.
These energy-efficient windows are particularly popular in Mid-Atlantic homes, where homeowners want to bring the outdoors inside year-round. The box-like structure creates a miniature greenhouse effect, ideal for growing herbs or succulents or displaying decorative items.
Standard Garden Window Sizes
Before adding a garden window to your home, it’s important to determine what size you’ll need. Garden window standard sizes have a wide range, with the most common units measuring anywhere from 36 by 36 inches to 72 by 60 inches.
Panels project outward from the house, giving the window a depth of 16 to 24 inches, with 17 inches being the industry standard. This projection depth is worth considering for Mid-Atlantic homeowners, especially when planning around exterior landscaping or HVAC units.
Most Popular Garden Window Dimensions:
- Small kitchen gardens: 24″ W x 32″ H to 36″ W x 36″ H
- Medium installations: 36″ W x 48″ H to 48″ W x 48″ H
- Large feature windows: 60″ W x 60″ H to 72″ W x 60″ H
While these measurements represent the most common garden window sizes, a quality window company can customize your garden window to fit an existing opening. At Thompson Creek, we custom-manufacture every garden window at our 120,000 sq ft Upper Marlboro, Maryland facility, ensuring a precise fit for your home’s unique specifications and eliminating the gaps common with stock windows.
Garden Window Components
No matter the size of your garden window, it consists of a few core parts. A boxy frame extends three-dimensionally from your home’s exterior, and four panels of insulated glass let in natural light from the front, sides, and top to create a welcoming environment for your plants.
Side panels typically open outward to let in a cool breeze, and some units include shelving for additional storage space. Thompson Creek’s garden windows feature professional-grade vinyl frames that won’t chip, peel, or require repainting, well suited to Maryland’s humid summers and freezing winters.
Best Locations for Garden Window Installation
By far, the most popular place to install a garden window is the kitchen. Many homeowners choose this space because it’s ideal for starting an herb garden or growing vegetables indoors. This window style is versatile, though, and can be installed anywhere in your home.
Popular installation locations include bathrooms for natural light and ventilation, home offices to create an inspiring workspace with greenery, living rooms to showcase decorative plants, and bedrooms for waking up to natural light. When planning your installation, consider how the window’s 16-to-24-inch projection will affect both interior and exterior aesthetics.
Planning Your Garden Window Project
Because garden window projects vary by size, materials, and level of customization, general cost estimates aren’t a reliable way to plan your project. Thompson Creek offers transparent, no-hidden-fee estimates through a free, no-obligation consultation, backed by our 50-Year No-Hassle Warranty covering both product and professional installation. Our installation teams ensure your custom replacement windows fit precisely and perform efficiently for decades.
Garden Windows vs. Bay Windows
Many homeowners wonder about the difference between garden windows and bay windows. While both project outward, garden windows are smaller, box-shaped structures with 90-degree angles and a glass roof, well suited to kitchens and bathrooms. Bay windows feature angled glass panels and are much larger, often creating seating areas in living rooms.
Energy Efficiency for Mid-Atlantic Homes
Mid-Atlantic homeowners face distinct climate challenges, with hot, humid summers and freezing winters. Thompson Creek’s garden windows are built with multi-pane insulated glass, Low-E coatings, and argon gas fills and are tested to withstand winds up to 146 mph. These features help reduce heating and cooling costs while creating a favorable environment for year-round indoor plant growth.
