What Are Arched Windows?
Arched windows refer to any window with a curved top. The curved portion can be a part of a single window frame, or it can exist in its own frame above a window or door. There are several types of arched windows based on the degree of curvature and the shape of the curve including round, half-moon, and other curved window designs. Learn about the most common types of arched windows to identify your own window.
Radius: Standard Arched Window
A Radius or Standard arched window features a curved, half-circle at the very top and a straight, rectangular body, all of which are connected in a single window frame.

Half Circle Arched Window
Also called the half-round or half-moon arched window, the half-circle is a semicircular design that often sits in a separate frame atop a rectangular window or a set of doors. A half circle can also be divided in half to create quarter-circle arched windows.

Elliptical Arched Window
An elliptical arched window is a wider semicircle, most often in a separate frame over large windows or doors. Just like a half-circle arch, an elliptical can be divided in half to create half-elliptical arches installed side-by-side over a window or door.

Full Chord Arched Window
Similar to a half circle, but typically shorter, the full chord window looks as if the circle has been cut closer to an edge rather than through the center. It is commonly installed in its own frame above a window or door. A full chord can also be divided in half to create half chords installed side-by-side over a window or door.

Full Arch Head Window
Similar to a radius or standard arch window, a full arch head features a shallow or subtle curve at the top of the frame with corners at the edge that align with a tall rectangular body. A full arch head can also be divided down the center to create a half or partial arch head.

What Is the Point of Arched Windows?
Arched windows are a beautiful architectural feature that improve the view to the outdoors and let in lots of natural light to brighten and warm your space. However, most of these windows do not provide ventilation as they cannot be opened. Adding arch window curtains can help control heat build-up from the unopened window.
why go custom?
Thanks to their beautiful unique shape, arched windows can sometimes make finding the right premade curtains difficult. Thatās why itās typically best to go with custom curtains for arch windows, as youāll be able to achieve just the right size, style and functionality to suit your needs.
Benefits of Arch Window Curtains
Because of their height and curved shape, arched windows often require more careful planning than standard windows. Curtains are often an ideal choice, as they can be positioned and styled in a way to best complement the window, from emphasizing its height to softening the overall look.
Explore more benefits of curtains for arched windows:
- Enhances the aesthetics of your space with long, lush panels that help accentuate the height of your arched window.
- Can be easily pulled off your window, with the right hardware and pleat style so you can easily enjoy your window when you want to and cover it when you need to.
- Provides light and privacy control by blocking some or most of the light coming through your arched windows or doors when the curtains are pulled shut.
- Improves the functionality of your space by reducing glare and heat buildup so you can enjoy the space in comfort more often.
How Do You Hang Curtains on an Arched Window?
There are two main ways to hang your curtains for arched windows: hanging the curtains above the arch on the wall or ceiling or hanging them just below the arch so the arch is always visible.
Above the Arch
Hanging your drapery above the arch on the wall or ceiling is a great solution if you want total light and privacy control by covering the arch and the windows or doors below it. By adding drapes for arched windows in this way, you’ll also accentuate the height of the window and ceiling, which makes your space feel bigger and more spacious.

below the arch
Hanging your drapery below the arch allows you to always view your beautiful window and enjoy the natural light it lets in while still giving you the privacy you need by covering the windows or doors below the arch. This application of curtains for arch windows will create a segmented look and can help very tall windows and ceilings feel less overwhelming in your space.

Another possible application is to hang your curtains over arched windows, positioned within the arch on a curved rod. This would require custom-made hardware and will only work if thereās enough space within the archās frame to install the rod. This method is often not the preferred route, as it is difficult to adjust the panels on the curved rod, making them not as functional as the first two options.
How to Measure for arched window curtains
Measuring for arch window curtains requires a very slightly different approach than standard windows, simply because you’ll need to decide whether to cover the full arch or just the window below the arch. To get started on measuring for your arch window curtains, learn how to measure for curtains on standard windows. You can apply many of the same principles to your curtains for arched windows.
Placement: Decide if your arch window curtains will be installed above or below the arch, as this will determine where you start measuring.
Height: Measure from your intended rod placement to the floor. For above-arch installations, placing the rod a little more than halfway up between the top of the arch and ceiling is a good rule of thumb.
Width: Measure the full width of the window and add about 6 to 12 inches beyond the window frame so panels can stack off of the window.
Accuracy: For the best results, especially with the nuances of custom drapery for arched windows, consider professional measuring. Our experts will ensure proper positioning so your drapes and window look their best.
Types of Curtains for Arched Windows
The types of curtains for arched windows are the same as those you can choose for any other window. However, choosing the right arch window curtains versus a regular window takes special consideration. Explore types of drapes in terms of pleat style, hardware, fabric and lining and learn about the best choices for drapes for arched windows to help you decide what works best for your needs.
Pleat Style
Pleat style refers to how the drapery is fashioned at the very top of the panel and how fabric falls off the panel. Pleat drapery styles range from sleek and modern to elegant and traditional ā and they also have different levels of functionality. Learn more about each pleat style to see which best suits your style and functionality needs for your curtains for arched windows.

Hardware
As youāve started to learn above, hardware plays an important role in the functionality of curtains for arched windows along with pleat style. But not all pleat styles are compatible with all types of hardware. Understanding your hardware options is essential for achieving the right functionality for your arched window curtains.
Hardware can be divided into two main categories: rod and rings systems and track systems.
Rod & Rings Hardware
The traditional rod and rings hardware consists of a curtain rod and rings to which the drapery panels are attached. To adjust your arched window curtains, you pull the panels and rings across the rod. While it sounds simple enough, the higher your drapery, the more difficult it becomes to move the panels. Plus, as you learned above, some pleat styles are simply harder to move than others.
track systems
Track systems feature carriers in a track to which the drapery is attached. The carriers glide effortlessly on their track, making adjusting your panels easy regardless of height. Plus, you also have the option of a motorized track system, which allows you to adjust curtains for arched windows with a remote, an app or even the sound of your voice when paired with a smart home system.
How to Choose Hardware
Since curtains for arched windows can be hung quite high if theyāre above the arch, functionality becomes much more important to your design. The right type of hardware will need to accommodate your needs and expectations for adjusting your drapery. If you plan to adjust your arched window curtains regularly, a track system or motorized track system is best for the easiest, most effortless experience. Just be sure to choose a pleat style thatās compatible with track systems.
Fabric & Lining
Your fabric choice has as much to do with the aesthetics of curtains for arched windows as it does with their functionality. Youāll need to think about the level of privacy and light control you want from your drapery to choose the right fabric. And if your fabric doesnāt give you the level of light and privacy control you need, youāll need to consider lining.
drapery fabric
Fabric options range from gossamer sheers to inviting thick wool blends and character-rich natural fibers to pristine synthetics. Finding the right fabric will depend on your aesthetic preferences as well as how much light and privacy control you need and your expectation for maintenance.
drapery lining
Lining options include privacy lining, blackout lining and interlining, which can be added to both privacy and blackout lining. Lining increases the privacy and light control of your drapery as well as insulation, especially with interlining. Plus, the added fabric adds body and fullness to your drape panels while also protecting them from the sunās harsh rays.

The horizontal lines create a sense of width for your doors and windows while the streamlined Tailored Pleat Drapery adds to the sense of height for a spacious feel throughout your room.

For an additional touch of luxury and visual interest to your drapery, consider adding lavish trim like Samuel & Sons Bali Cord or Seychelles Wood Beads.

What are the best window treatments for arched windows?
Curtains are one of the most versatile arched window treatments because they can be installed above the arch or below it depending on your preferences. While window curtains for arched windows provide flexibility and a wide range of styles, other solutions like shades or blinds may be better suited for your particular application. The best option depends on how much light control, privacy, and adjustability you want from your space.
Can curtains be used on different shapes like curved or round windows?
Yes, many of the same solutions used for curtains on arched windows can be applied to other curved windows or round window designs. Depending on the shape, curtains for arched window applications may be installed above the frame with traditional hardware, or adapted with specialized, curved hardware that accentuates the the elegant shape of your window while maintaining functionality.
Should curtains cover the entire arch or just the lower part?
Curtains over arched windows can be installed to cover the full height when maximum light control and privacy are needed, or positioned below the arch to keep the curve visible. To highlight the half-moon shape while still covering the lower portion of the window for privacy, hang your rod below the arched portion. However, for greater light control and a dramatic look, hang your curtains for arched windows high to cover the full arch.
