Hang Curtains on Corner Windows Like a Pro

When we first moved into our new home, the corner windows in the living room left me both inspired and frustrated. I had this exciting feeling of making the space beautiful but also felt completely stumped. We had been through unusual layouts before, but this one stood out. The window ran across the back wall and met another on the side, making it a bit tricky. It’s not a common feature you often find in primary rooms like bedrooms, so it’s easy to feel stuck. After browsing every blog, old post, and review, I finally found easy and practical methods that work. The biggest mistake is treating each window as separate. I quickly realized that the right approach was to treat it as one large unit—a decision that changed the whole room.

We used two main styles for hanging the curtains, both of which I’ll explain. One was a custom DIY setup, and the other was an adjustment of pre-made rods. The thing that was most important to me was keeping the look flowing, not broken—so instead of breaking the view with separate rods, we chose continuous ones. It might sound tricky, but it was the best solution for our situation. If you’re reading this, you’ve probably also been stuck on how to hang curtains on corner windows—and you’re definitely in the right place. I’ll tell you how we made it work, what didn’t, and what we absolutely love. This blog exists to share such practical experiences, and I’m confident that no matter how unique or awkward your window setup is, there’s a way to deal with it and successfully dress them in style.

How to Hang Corner Curtains the Traditional Way

When it comes to corner window curtains, the traditional method still works best if done right. I’ve installed these in my own home, and over time, I’ve learned that following the proper steps makes the process simple and clean. First, gather your tools: a measuring tape, ruler, pencil, drill, screws, anchors, and a level. Your brackets need to be installed on the wall, ceiling, or window frame, depending on your space.

Use anchors if you’re drilling into drywall, unless hitting studs. Make sure everything is lined up correctly, and don’t skip reading the installation instructions that come with your curtain rod corner kit. Proper direction helps ensure your rods have full support and avoids mistakes. This method is one of my go-to curtain-hanging ideas, especially when I want a clean look with little hassle.

To hang the curtains, simply connect your rods using a connector or even a plastic elbow for a budget-friendly hack. In fact, one of my favorite curtain hacks is using pieces from the plumbing section at hardware stores—you can find a piece that fits and spray-paint it to match your existing setup. Once your rods are connected, remove a finial, attach the corner piece, and slide your curtains into place.

The mounting process should feel smooth if you’ve measured properly. Take your time, enjoy the process—it’s actually kind of fun when you get into it. This method involves careful setup, allowing a seamless transition between the two sections, which is why it’s one of my top corner curtain tips. If you’re looking to save money, these small adjustments can make a big difference in both function and style.

How to Hang Corner Curtains the Easy Way

If you’re dealing with tricky window curtains or trying to solve an awkward window fix, there’s no need to go the traditional route with drills and measuring. I once had to handle hanging corner curtains in a rental, and I wanted something clean and fast. That’s where Kwik-Hang made things easier. Just position the brackets at the top corner of the outer edge of the window frame, then tap them in with a hammer—no drill, level, or stud finder needed. These no-drill, labor-free, zero-damage brackets are a great alternative for anyone who wants quick results with minimal effort. It’s especially helpful in small-space curtain setups where tools are hard to manage or wall damage is a concern.

To complete the setup, I placed the center support about 4 inches from the inner corner, then slid my rods into place. I had to remove a finial and used a connector (though it’s optional) to join the rods smoothly. The brackets aligned the corners perfectly, and within seconds, my curtain rod was up—neat, balanced, and stable. Whether you’re updating your selection or want to explore faster options today, this setup works without needing a measuring tape, tape, or extra tools. Just a few taps, and you’re done.

Measure for Curtains and Rods

Before you install your curtain rods, it’s important to follow a proper curtain measurement guide. I’ve found that taking a few extra minutes to measure the window width, including the trim and casing, saves a lot of trouble later. You’ll want to determine the placement of your rod — whether inside the frame, above the window, or even closer to the ceiling for a taller look. Carefully measure from the rod to the floor, sill, or whichever bottom point you want as your desired length. Don’t forget to adjust for hardware like rings, which can affect your final length. For fullness, I always multiply the width by 2, or sometimes 2.5 if I want a more gathered effect. For a tailored style, 1.5 works well. Always add about 6 to 12 inches (15 to 30 cm) on each side for extension, so your curtains can stack neatly when open.

When selecting the rod length, remember to include both sides and account for the finials, especially if they are decorative end pieces. To get a good overlap when the curtains are closed, I like to add another 5 to 10 inches (12.7 to 25.4 cm). A solid rule is to choose a rod that’s the window width plus 16 to 20 inches. For example, if the window is 48 inches, aim for a rod around 64 to 68 inches. These small details — from mounting height to panel length — will give your curtains a full, finished look. My personal tip: always base panel size on the total rod length, not just the window, to ensure your setup looks proper and common mistakes are avoided.

The Corner Curtain Conundrum

In our Master Bedroom back in Kansas, we had a real challenge — two skinny windows placed tightly in the far corner of the room. Their perpendicular placement made it incredibly difficult to hang curtain rods the traditional way, and during storms, the winds came roaring down the plains, creating a loud sound experience. Most people might go for roman shades, valances, or cornice boxes, but I’ve always preferred the same basic black curtain rods throughout all our homes for visual continuity and smoother shift of treatments between one house and another. I really wanted to find a way to use standard curtains in this corner and still make them work efficiently to protect curtains from wind.

My favorite part about DIY curtain hanging is finding solutions that are affordable and practical. Rather than invest in special rods, I looked for simple curtain rod hacks. I could have bought a corner rod piece from Target, Bed Bath & Beyond, or Amazon, but I stumbled upon a little plastic elbow for just $0.99 in the plumbing section at Lowes — and it was exactly what I needed to connect our existing rods. This small piece allowed us to adapt our setup and follow our usual curtain setup guide without spending much. It was an easy fix that didn’t compromise the style or function and helped us save money while achieving the look we wanted.

What is the Best Cover for Corner Windows?

The best cover for corner windows is a double curtain setup using blockout fabric and sheer fabric. This combination treatment not only offers excellent light control and privacy but also adds a softer, more decorative touch to the space. When installed with a corner connector rod, curtains can effectively frame both sides of the corner without gaps, making them an ultimate solution that blends function and style.

That said, there are other excellent choices depending on your space. Plantation shutters offer a sleek, custom look that fits seamlessly into modern interiors. For a minimalist feel, roller blinds or cellular blinds are both practical and neat, while Roman blinds bring a tailored, elegant vibe. If you’re looking for something unique, angled pelmets paired with custom shades or traditional blinds can be a stylish combination treatment. Each option has its strengths—the key is to choose the one that fits your needs and enhances your corner windows most effectively.

How to Avoid Sagging in Corner Curtain Rods

If you’re struggling with window curtains for room corners, sagging rods can be frustrating—especially in L-shaped window curtains setups. I’ve dealt with this in my own home, and the solution always starts with proper support. To avoid any sagging, make sure your curtain rods are supported every 30 inches. I usually use a center support bracket to strengthen the rod, especially on wide windows with heavier fabric. Don’t skip precise measurements, and be sure to secure the brackets using anchors or longer screws if needed. These small details can eliminate issues like drooping or collapsing, giving your setup a strong, clean finish.

One of my favorite fixes is using Kwik-Hang brackets. They’re affordable, easy to install, and fit perfectly—a great option if you want a simple installation process without damage to your walls. Just tap them into place—no tools, no hassle. When working on a DIY corner curtain rod for windows, especially in tricky edge spaces, I also recommend using thicker, durable material to reinforce the rod. These hacks make a big difference. If you’re new to this, take time to learn about swag curtains too; they add a soft finish and help balance the weight for better support. Try it today—it’s easier than you think.
