How to Hang Curtains on an Arched Window
What You'll Need
- Tape measure
- Pencil
- Level
- Stud finder
- Screws
- Screwdriver or drill
- Drywall anchors
Step 1: Pick a Curtain Rod Placement
When hanging curtains on an arched window, you can place the curtain rod either above or below the arch. Hanging the curtains above the arch can give your space an elongated look and provide full window coverage for both sun protection and privacy. Installing the curtain rod right below the arch allows you to see this beautiful architectural detail while maintaining privacy for the window below.
Step 2: Measure Your Windows
Once you’ve decided on your curtain rod placement, you'll need to measure your windows to find the right size for both the curtain rod and the curtains.
Width: When calculating window width for curtains, use a tape measure to measure from one side of the window casing to the other, then add 6" per side to your measurements to account for pleats or folds. Similarly, the curtain rod should be 8" – 12" wider than the total width of the window.
Length: Length is more of a style preference, so you should decide if you want the curtains to hang past the bottom of the window, to touch the floor, or to pool slightly at the bottom. To measure for length, measure from where you plan on installing the curtain rod to where you want the curtains to end.
Height: If you're installing your curtains above the window, you'll most likely mount the curtain rod 4" – 6" above the top of the window frame, so you should measure from that height to your desired curtain length. If you're placing your curtain rod below the arch, measure from the base of the arched section to your desired curtain length. Check out our guides How to Measure for Curtains and How to Measure for Curtain Rods for more details about this step.
Step 3: Determine Which Type of Curtains
After you've determined which size would be best for your windows, it's time to choose the right type of curtain. The material, color, and opacity can impact the look and feel of each curtain, so you should consider which details would pair best with your decorating style. Our guide Types of Curtain Materials includes all you need to know about choosing the best curtains for your space.
Step 4: Choose Your Curtain Rod
Curtain rods and curtain hardware come in a variety of finishes, ranging from shiny white to metallic to matte black. Though matching the curtain rod and hardware to other finishes in the room is the most cohesive option, choosing a curtain rod with a different finish is also an opportunity to create a stylish mix throughout the space.

Step 5: Measure & Install the Brackets
If you're installing the curtain rod above the window, use your tape measure and pencil to mark 4" – 6" above the window and use a level to see if the marks are even. Then mark 2" from each side of the window to indicate how far out the brackets should be placed.
If you're installing the rod right below the arch, you can use architectural features (like window panes or trim that separates the rectangular portion from the arch) to help you find the correct height. From there, mark 2" from each side for accurate placement.
Because this is where you'll install the brackets, you'll need to use a stud finder to determine if the marks are located on top of a wall stud. If so, use a drill or screwdriver to install the brackets. If there isn't a wall stud, drill a pilot hole and install a drywall anchor to help support the weight of the brackets.
Step 6: Install the Curtain
Once the brackets are installed, attach the curtain to the rod by threading the rod through the curtain's pocket or grommets or by securing the curtain with curtain rings. Then, secure the curtain rod into the brackets. Some brackets feature hooks where the curtain rod will rest, while others require you to screw the rod into place. Replace any finials on the end of the curtain rods and adjust the curtains to your desired look.
