How to Hang Curtains on Arched Windows

It can be difficult to hang curtains on an arched window. Still, with the appropriate methods and suggestions, you can create a stunning and useful window treatment that accentuates the distinctive curve of your window. In this article, we’ll provide step-by-step instructions for measuring and hanging curtains on an arched window, additionally advice on picking the appropriate hardware and curtains. Whether you’re a DIY enthusiast or looking for professional assistance, this guide from Curtain Design Home will help you achieve a stunning look for your arched window.

Measure and Plan

Before you choose your curtains and hardware, measuring your arched window accurately is essential. Unlike a rectangular window, an arched window has a curved top that requires special consideration when sizing your curtains and selecting your hardware.

You’ll need a tape measure, a ladder, and a helper if possible to measure your arched window. Measure the width of your window at its broadest point first. Next, measure the height of the window from the top of the arch to the bottom of the window. Finally, measure the arch length from the centre of the window to where the arch begins.

Once you have your measurements, you must choose the right hardware for your arched window. Several types of hardware are available, including curved curtain rods, flexible tracks, and arched curtain rods. Curved curtain rods are ideal for small or partial arches, while flexible tracks are better suited for larger or irregularly shaped arches. Arched curtain rods provide a more traditional look and are ideal for formal or classic window treatments.

Choose the Right Curtains

The shape of your arched window will influence the type of curtains you can use. Traditional rectangular curtains may not be suitable for an arched window, as they won’t fit the curved top of the window. Instead, you’ll need to choose a style that complements the shape and style of your window.

One option is to use drapes tailored to your arched window’s shape. This type of curtain is typically made of fabric that is cut and sewn to precisely fit the shape of your window. Drapes can be hung on a curved rod or a flexible track, providing a luxurious look perfect for formal living areas.

Another option is to use customised Roman shades to fit the size and shape of your arched window. Depending on your preference, Roman shades can be mounted inside or outside the window frame. They’re an excellent choice for rooms where you want to maintain privacy but still let in natural light.

Curtains with tiebacks can also work well on an arched window. The tiebacks will hold the curtains in place on either side of the window, allowing the natural light to shine through the arch. This option is ideal for rooms where you want to maximize natural light and create an airy, open feeling.

Hanging Your Curtains

Once you’ve selected your curtains and hardware, it’s time to hang them on your arched window. Depending on the curtains and hardware you choose, the procedure will change, but the following steps provide a general guide:

Step 1: Mark the position of your hardware. Use a pencil to mark where you want to install your hardware. If you’re using a curved rod, you’ll need to measure and mark the position of the brackets on either side of the window.

Step 2: Install your hardware. Follow the instructions provided with your hardware to installing the brackets or track. If you’re using a curved rod, you may need to bend it slightly to fit the shape of your arch.

Step 3: Hang your curtains. Once your hardware is installed, it’s time to hang your curtains. If you’re using drapes, attach the drapery hooks to the top of the fabric and then hang them on the rod or track. If you’re using Roman shades or curtains with tiebacks, follow the instructions to install them.

Step 4: Adjust the length and fullness of your curtains. Once your curtains are hung, you may need to adjust their length and fullness to ensure they look great on your window. For drapes, adjust the length by hemming the fabric or using drapery weights to hold them in place. You can also adjust the fullness by adding or removing panels or using different styles of drapery hooks.

Step 5: Use tiebacks and accessories to enhance the look of your curtains and window. Tiebacks are an excellent way to add style and functionality to your curtains. They can be made of fabric, tassels, or other decorative materials and hold your curtains in place when they’re open. Other accessories you may want to include valances, cornices, and swags, which can add depth and dimension to your window treatment.

Here are some additional tips to consider while hanging curtains on arched windows:

Consider the material and weight of your curtains. Arched windows can be particularly challenging if your curtains are heavy or thick. Consider using lighter fabrics or sheers that can be easily draped and won’t add too much weight to the hardware.

Use tension rods for temporary or rented spaces. Tension rods can be a great temporary solution if you cannot install permanent hardware on your arched window. These rods can be adjusted to fit the shape of your window and are held in place by tension, eliminating the need for screws or nails.

Layer your window treatments. Adding layers to your window treatments can help to create a more complete and polished look. Consider using shades or blinds underneath your curtains for privacy and light control.

Be mindful of the height of your curtains. When hanging curtains on an arched window, it’s important to consider the height of your curtains and how they’ll be mounted. Curtains mounted too high can make your room feel smaller, while curtains mounted too low can make your window look awkward and disproportionate.

Experiment with different styles and shapes. Arched windows are a unique and visually interesting feature, so don’t be afraid to experiment with different styles and shapes of curtains to find the perfect look for your space. You should experiment with various materials, hues, and patterns until you find the ideal suit for your house.
