We carefully choose our curtain rods and curtains, already imagining the drape of the linen in the morning light... and then, at the very last moment, we stumble upon a seemingly innocuous question: how, and more importantly where, should we fix the supports?
Yet, it's this small detail that dictates everything. Since 2014, we've been dressing windows, and we see it every time: a well-placed rod goes unnoticed, and all you see is the curtain and the beautiful light it filters. A poorly placed rod, conversely, stands out and pulls down the entire room's decor, even the most carefully chosen.
For us, this curtain rod is never just an accessory: it's our COSYCHIC rod, a solid wood pole handcrafted, with each piece being unique. Placed above a window, it transforms a utilitarian fixture into a genuine decorative element, and as we see with each installation, it enhances any curtain, whether it's washed linen, light voile, or a thicker fabric. All that remains is to install it correctly, and that's where the support comes in.
The good news is that there are no inaccessible professional secrets involved. You just need to understand what a support actually does, and then choose the right one for your window. This is the whole purpose of this guide: we will see what a support is really for, which model is suitable for each situation (facade, wall-to-wall, recess, ceiling, double curtain), at what height and with what setback to install the rod, and how to avoid mistakes that otherwise spoil a successful installation.
First, understand what a support does
We often think that a curtain rod support only serves to "hold the rod." In reality, it does two very different things, and by keeping these two roles in mind, all your choices become obvious.
First role: bearing the weight. A curtain rod, especially when loaded with a linen curtain, weighs more than you think, and this weight constantly pulls on the fixings. The support and its plug must therefore be adapted to the wall and the load, otherwise the rod sags or, worse, eventually detaches.
Second role, equally important: positioning the curtain in space. The support decides three things at once: at what height the curtain starts, how much it extends on the sides, and at what distance from the wall it hangs. These three adjustments are what make a window appear larger, brighter, better proportioned... or not.
Keep this dual function in mind: everything else in this guide stems from it.
Which support for which window?
On the facade: the most common case
This is the classic situation: you have a solid wall above the window, and the supports are fixed to the facade, on either side. The rod rests on them, in front of the wall.
Why is this the most comfortable case? Because it gives you complete freedom over the three adjustments we just talked about: you raise the rod as high as you want, you extend it as much as you want, and you choose the setback from the wall. It's the most flexible installation, ideal whenever you have some wall space available.
For this case, our V-shaped metal wall bracket holds the rod in an open cradle. Its graphic line naturally blends with raw wood poles, and its V-shape accommodates both a thin rod and a thicker pole.
From wall to wall, or in a niche
This is one of the configurations that comes up most often in our discussions with clients. A window in a niche, an alcove, a recess, a closet to close, or even installing a shower curtain: whenever a rod needs to be stretched from wall to wall, many wonder what solution to adopt.
The common point between all these situations is simple: there is no wall available above the opening to fix classic facade supports. The only fixing points are on the side walls.
The solution is the side-fixing bracket. Instead of screwing into the back wall, it is fixed to the two side walls, and the rod is literally stretched from one wall to the other. The enormous advantage: no need for any central support, so the curtain slides across the entire width without ever snagging, and the whole thing disappears once the window is dressed. It's clean, it's invisible, and it's exactly what you expect from a well-executed niche.
This is precisely the role of our V-shaped bracket for wall-to-wall installation.

On the ceiling
Sometimes, there simply isn't enough space above the window: a bay window that almost reaches the ceiling, a sloping ceiling, or a lintel that's too short. In such cases, we fix it to the ceiling rather than the wall.
But be careful, ceiling mounting is not just a fallback solution: it's also a true aesthetic choice, and one of the most rewarding. By hanging the curtain from the very top, you create a vertical line running from the ceiling to the floor, and this line visually stretches the height of the room. This is the trick decorators use to add grandeur to a living room or bedroom.
The technical point to know: the depth of the ceiling support must be chosen according to your ceiling height. If your ceiling is low, a short support is sufficient (the rod stays close to the ceiling, the curtain starts high, the room breathes). If your ceiling is high, you have the choice between letting the curtain fall from the ceiling or lowering the rod with a deeper support.
Our ceiling hook is available in several depths (5, 10, 15 and 25cm) to adjust the position of the rod to your configuration.
And if your bay window exceeds 2.50 m, ceiling mounting requires a special trick to assemble two rods without an unsightly joint: we explain everything, with photos, in our article dedicated to wide bay windows.
Sheer and curtain: the double rod
The last case, very popular: you want to superimpose a light sheer curtain and a more opaque curtain. The principle is to mount two parallel rods, one in front of the other: the sheer curtain in front, which filters the light and preserves privacy during the day, and the curtain behind, which is drawn in the evening for darkness and warmth.
This is the most complete solution for controlling light throughout the day, and it truly changes the comfort of a room that is used from morning to night, such as a living room or bedroom.

The wooden pole, the soul of the curtain rod
We've talked a lot about the supports, because they're what hold the curtain and make it hang well. But what we see, what we notice when entering a room, is the rod itself. And that's where the style comes in. That's the whole spirit of our COSYCHIC range.
Our poles are made of solid wood, handcrafted, and each piece is unique: the nuances, the grain, the small irregularities of the wood tell us that no two are alike. Placed on its black metal supports, the pole creates that contrast we love so much: the warmth of raw wood against the graphic line of forged metal. It's this duo that gives the window its natural and handcrafted character.
And the most reassuring thing, when you're still undecided about your curtains: whatever fabric you hang next, be it washed linen, airy voile, or a denser curtain, the result is superb. The pole enhances the textile, never the other way around.

How high should the curtain rod be placed?
This is the adjustment that is most often missed, by reflex: we tend to place the curtain rod just above the window, flush with the frame. This is a shame, because height is precisely the most powerful lever to transform a room.
The basic rule: place the curtain rod 10 to 15 cm (4 to 6 inches) above the window frame.
The decorators' secret: go even higher. You can place the rod halfway between the frame and the ceiling, or even a few centimeters below the ceiling. Why does it work? Because the eye follows the line of the curtain from top to bottom. The higher this line starts, the larger the window appears and the further away the ceiling seems. This is exactly the desired effect in rooms with low ceilings, or to add grandeur to a somewhat modest window. The curtain then covers the wall above the window, and no one guesses that the glass itself stops much lower.
How much should the curtain rod extend beyond the sides?
Another reflex to correct: cutting the curtain rod to the exact width of the window. This guarantees a darker room and a window that appears smaller than it is.
The rule: extend the curtain rod 15 to 20 cm (6 to 8 inches) on each side of the frame, and don't hesitate to go up to 30 cm (12 inches) for a more generous effect on a large window.
The reason: when you open the curtains during the day, the fabric should be able to retract onto the wall, on each side, and not remain in front of the window. This overhang is what frees up the entire glazing: you gain natural light, and the window appears significantly wider. Without this clearance, even when wide open, your curtains block some of the daylight and compress the opening.
What distance should there be between the wall and the curtain?
This is the detail that almost no one talks about, yet it ruins an incredible number of installations: the curtain dragging on a radiator placed under the window, or bumping into the handle of a tilt-and-turn window that can no longer be opened.
The cause is always the same: the curtain rod is placed too close to the wall, and the curtain does not have room to hang freely. The solution is just as simple: a support that moves the rod away from the wall, to create the necessary space. The curtain then hangs straight, in front of the obstruction and not on it.
15, 20 or 25 cm: which depth to choose?
Our offset support creates the necessary space between the wall and the curtain so that it hangs freely, without rubbing or getting stuck.
- 15 cm (6 inches) are suitable for most common situations: window handle, small radiator or shallow overhang.
- 20 cm (8 inches) offer more setback for thicker radiators or more pronounced window sills.
- 25 cm (10 inches) are recommended when the obstruction is significant: large radiator, deep shelf or specific configuration.The offset support is also very useful when the casing of a roller shutter protrudes above the window. By moving the rod away from the wall, it allows the curtain to pass in front of the casing and hang perfectly straight, without obstruction or deformation of the fabric.
How many supports do you really need?
This is a question we are often asked. Many people think that a 2-meter curtain rod necessarily requires a central support. In reality, everything depends on the length of the rod, its solidity, and the weight of the curtains.
At COSYDAR, our solid wood curtain rods are designed to be installed with only two supports up to 200 cm (approx. 78 inches) in length. A support at each end is then sufficient to ensure good hold and smooth curtain gliding.
Beyond 200 cm (approx. 78 inches) in length, we recommend adding a third central support. This helps to bear the weight in the middle of the rod and prevent it from sagging over time, especially when the curtains are heavy or very tall.
Key points to remember:
- Up to 200 cm: 2 supports are sufficient;
- Beyond 200 cm: plan for 3 supports (2 at the ends and 1 in the center);
- For particularly heavy curtains, it may be wise to further reinforce longer lengths.
Small installation tip: position the end supports a few centimeters from the ends of the rod. This distributes the load better and makes the rod more stable over time.
To choose the right curtain rod length and the number of supports suitable for your project, also consult our complete guide: "How to choose your curtain rod?".
Installing on a fragile wall: plasterboard, hollow partition
This is the number one fear, and it's legitimate: "What if everything falls down on me?"
Remember the primary role of the support: to bear the weight of the curtain and the rod. But this weight is not static. A curtain is a daily element that is opened and closed regularly, sometimes several times a day. Each manipulation exerts a pull on the rod, supports, and fixings. A poorly suited wall plug can hold for a few weeks or months, then eventually loosen under the effect of these repeated stresses.
The right approach is therefore to choose the wall plug according to the type of wall:
-
Plasterboard or hollow partition: use an expansion plug like a Molly plug, which opens behind the board and distributes the force over a larger surface. Avoid simple screws fixed directly into plasterboard: they risk being pulled out with repeated opening and closing of the curtain.
-
Hard wall (concrete, solid brick): a hammer-in plug or a plug suitable for concrete provides a reliable and durable solution, perfectly capable of supporting the weight of the rod and daily handling.
Mistakes to avoid
-
Choosing a rod that is too short
A rod limited to the width of the window prevents the curtains from fully clearing the glass when open. The room then appears darker and the window seems smaller than it actually is. -
Underestimating the number of supports
Up to 200 cm, two supports are usually sufficient. Beyond that, a central support becomes essential to prevent the rod from bending under the weight of the curtains, especially with thick linen or great heights. -
Fixing the rod too low
A rod placed just above the window frame visually reduces the height of the room. By positioning it higher, you instantly enlarge the window and add more elegance to the whole. -
Neglecting the offset from the wall
A rod too close to the wall can prevent the curtain from hanging properly. A radiator, window handle, or shelf can then hinder its movement and cause premature wear of the fabric. -
Using unsuitable fixings
Even the most beautiful rod will not last long with poorly chosen wall plugs. Plasterboard, brick, or concrete require specific fixings. An adapted fixing guarantees the solidity and longevity of the installation.
The right support, whatever your window
Facade, wall-to-wall, recess, ceiling, double rod, offset for radiator: there is a specific solution for each configuration, and that's the advantage of having choices. But don't forget the essential: the support serves the rod. It holds, it adjusts the height and setback, but it's the handmade solid wood, placed on it, that creates the style. This contrast of raw wood and black metal defines a natural interior.

Frequently Asked Questions
What is a COSYCHIC curtain rod?
COSYCHIC is our range of solid wood and forged black metal curtain rods. Each rod is handcrafted and unique, to adorn facades, recesses, ceilings or large bay windows with the same natural and artisanal spirit.
How to fix a curtain rod between two walls, without a central support?
With side-fixing supports: they are screwed to the side walls and hold the rod from wall to wall, without any central support. The curtain then slides across the entire width. This is the ideal solution for a recessed window or alcove.
How high should a curtain rod be installed?
Count at least 10 to 15 cm above the frame. To visually enlarge the room, go higher, up to halfway to the ceiling or just below: the higher the curtain starts, the larger the window appears.
How much should the rod extend beyond the window?
15 to 20 cm on each side, sometimes up to 30 cm on a large window. This overhang allows the curtain to be stored against the wall when open, thus clearing the entire window and light.
My curtain touches the radiator or hits the handle, what should I do?
Use an offset support. By moving the rod away from the wall, it allows the curtain to fall freely in front of obstacles such as a window handle, a radiator, a roller shutter box or a shelf. The fabric thus maintains a beautiful drape and slides more easily every day.
Our offset supports are available in several depths: 15 cm, 20 cm and 25 cm. Depending on your window configuration, they effectively clear elements that would prevent the curtain from falling correctly or opening without constraint.
How many supports for a 2 m rod?
For a 200 cm rod, two supports placed at the ends are generally sufficient. Our solid wood rods are designed to offer good rigidity over this length.
Beyond 200 cm, we recommend adding a third central support to better distribute the weight of the curtains and ensure perfect long-term stability, especially with tall linen curtains or heavier fabrics.
How to fix a curtain rod on plasterboard?
With expansion plugs like Molly plugs, suitable for hollow partitions, never just a simple screw.
