The bedroom is the room of the house where we spend, on average, a third of our lives — and it is also the one that depends most on light (or the absence of it) to work well. Even so, the choice of curtains is often made in a hurry, frequently at the end of a renovation, when there is neither time nor patience left to think carefully about fabrics, colours and function. This guide goes through each of those decisions in detail, so that the final choice serves the bedroom for years, not just until the next urge to change things.
Why the bedroom curtain deserves more attention than the others
Unlike the living room or the kitchen, the bedroom has a biological function tied to light: the body regulates sleep largely through exposure to (or protection from) brightness. A badly chosen curtain can mean waking at sunrise at 6 a.m. in summer, or never getting a room dark enough to sleep well during the day, in the case of shift workers. That is why, although aesthetic criteria still matter, in the bedroom they always come after function.
Fabrics: the foundation of everything
Fabric is the decision that conditions all the others — it determines how the curtain filters light, how it hangs, how it ages with use and how much work it takes to maintain.
Linen and cotton
These are natural fabrics, with a loose, informal drape. They let diffused light through even when closed — they never fully darken the bedroom, but they soften the entry of direct light, creating a calmer atmosphere in the morning. They are breathable and age well visually (linen in particular takes on a more textured, natural look over time), but they crease easily and are generally not machine-washable without the risk of shrinking.
Synthetic fabrics and blends
Polyester, viscose and blends of natural and synthetic fibres offer a good balance between appearance and practicality. They hang well, keep their colour longer without fading in sunlight, and are more resistant to daily use — the most sensible choice for those who don’t want to think much about maintenance.
Velvet and heavy fabrics
They block more light and sound than light fabrics, even without being technically blackout, and have a stronger visual presence — they help to visually “close off” the space at night. They are the most common choice in master bedrooms where a more enveloping atmosphere is sought. The downside: they collect more dust, weigh more physically (which calls for a sturdier rod or track) and aren’t always easy to wash at home.
Technical blackout fabrics
Designed specifically to block almost all light, with an opaque inner layer (often foam or an acrylic coating). The most practical option for shift workers, for those with small children who need naps, or for anyone who simply sleeps better in total darkness. Nowadays there are blackouts with an outer finish identical to any other decorative fabric, so functionality no longer means giving up aesthetics.
What to consider before deciding
- Climate and window orientation: a south- or east-facing window receives much more direct light than a north-facing one — which may justify a more opaque fabric even without the need for full blackout.
- Allergies and dust: heavy, textured fabrics collect more dust; people with respiratory allergies benefit from smooth fabrics that can be washed regularly.
- Washing frequency: always confirm whether the fabric can be washed at home or requires dry cleaning — this has a direct impact on maintenance costs over the years.
Colours: balancing light and atmosphere
The colour of the curtain influences the light that enters the bedroom even when it is open, through its reflection on the wall, the ceiling and the bedding.
Light, neutral tones (beige, ecru, light grey, ice white) visually enlarge the space and reflect more light, even when the curtain is drawn — a good choice for small bedrooms or those with little natural light, where you want to keep a feeling of spaciousness.
Dark tones (graphite, dark green, navy blue, chocolate brown) create a more intimate atmosphere and absorb light instead of reflecting it, which reinforces the effect of a cosier bedroom at night — but can make an already small or dimly lit bedroom feel even heavier during the day.
Accent colours (terracotta, forest green, mustard) work best as a single focal point — if the curtain is the strongest colour in the bedroom, the rest of the decor (wall, bedding, rug) should deliberately stay more neutral, so as not to compete.
A practical rule worth following: the colour of the wall and the bedding should be the starting point, not the curtain. The curtain should rarely compete with those two surfaces — its role is to complement, not to vie for attention.
If the bedroom already has many decorative elements (patterned wallpaper, pictures, a textured rug), a plain curtain helps balance the whole and avoids visual overload. If the bedroom is more neutral and a “blank canvas”, the curtain can be precisely the element that brings colour, pattern or texture to the space — an economical way to add personality without touching walls or furniture.
Blackout and privacy: two different needs
It is a common mistake to confuse blackout with privacy — they are distinct properties that don’t always go together.
Blackout refers to blocking light. It is essential for those who sleep during the day, have east-facing windows in a bedroom where the sun comes in early, or are simply sensitive to brightness on waking. A quality blackout blocks between 95% and 100% of outside light.
Privacy refers to not being seen from outside, even with light coming in. It is especially important in ground-floor bedrooms, with windows close to other homes, or facing the street.
A curtain can have one of these properties without the other:
- A thin, light fabric can provide privacy (it doesn’t let the interior be seen clearly) without blocking light significantly.
- A dark fabric with an open weave may, surprisingly, provide neither on its own — dark colour does not imply opacity.
For those who need both, the most effective solution is usually a two-layer curtain: a light, translucent fabric for the day (which ensures privacy and lets soft light in), with a blackout behind it that is closed at night. This combination, with two rods or a double-track system, is today the most common option in interior design projects — because it gives total control over light depending on the time of day, without forcing a choice of just one function.
Tips by decor style
Minimalist bedroom: plain curtains, in a single neutral colour, floor-length, with no patterns or decorative trims. The wave heading is the choice most associated with this style — it gives a clean, continuous finish, without the visual bulk of a traditional gathered heading.
Classic bedroom: more structured fabrics, with a traditional gathered heading, in richer tones (burgundy, bottle green, gold, petrol blue). Trims such as fringes, cords or decorative bands reinforce the style without looking dated, as long as the rest of the bedroom follows the same register.
Scandinavian/Nordic bedroom: natural fabrics, light tones and visible textures (raw linen, cotton), with no heavy patterns — the curtain should seem almost an extension of the wall, not an isolated statement element.
Child’s bedroom: washable, easy-to-clean fabrics (accidents happen), ideally with good light-blocking capacity to help with naps and an earlier bedtime than adults’. Avoiding loose cords or mechanisms within reach of small children is also a matter of safety, not just style.
Master bedroom with a balcony or large window: in these cases, the wave heading or a single wall-to-wall panel usually works better than two symmetrical panels — it covers the full width without creating an empty “frame” in the centre when the curtain is open.
Measurements: the most common mistake (and the easiest to avoid)
Even those who get the fabric and colour right often get the measurements wrong — and it is that mistake that most compromises the final result visually.
- Width: the rod or track should extend beyond the window by 15 to 30 cm on each side. This allows the curtain, when open, not to cover the window and to let in all the available light.
- Height: for a more elegant effect, the curtain should go to the floor (or stop 1–2 cm short, so it doesn’t drag). Stopping halfway down the wall or above the windowsill tends to visually “cut” the ceiling height and make the bedroom look lower.
- Amount of fabric: for gathers with visible body, allow between 2 and 2.5 times the width of the rod. Less than that results in a curtain that looks “stretched” and not very elegant.
These measurements vary with the type of heading and the intended effect — which is why made-to-measure production, with professional guidance on the measuring, avoids practically all the most common mistakes in this process.
Made-to-measure curtains: why they make a difference
The options available ready-made are standardised in fixed sizes, which rarely fit perfectly on a window with an unusual ceiling height, an irregular opening, or a whole wall you want to cover from end to end. Made-to-measure curtains solve that problem from the start: the fabric is cut and made up exactly for the space, with nothing left over and nothing missing, and without having to compromise on fabric or colour just because that is what is available in a standard size.
There is also a less obvious advantage: exclusive fabrics — patterns, textures or compositions not found ready-made — are only accessible through made-to-measure production, because they are cut and worked to order.
At Giestas Mobiliário, bedroom curtains are made to measure, with access to exclusive fabrics ranging from the simplest linen to the most elaborate velvets, including technical blackout options. The whole process is supported, from measuring the window to the final installation, so that the result truly fits the space and the style of whoever will use it — without the typical compromises of a ready-made solution.
Frequently asked questions
Should curtains always touch the floor?
In most cases, yes — it gives the most elegant finish and visually “closes off” the space. The exception is when a physical obstacle (radiator, low furniture) prevents it.
Does blackout make a curtain look less decorative?
Not necessarily. Today there are blackout fabrics with the same outer finish as an ordinary decorative fabric — the opaque layer is hidden on the inside, invisible to the naked eye.
Is it worth investing in made-to-measure curtains for just one bedroom?
It depends on what is at stake: if the window has a common size and there are no specific fabric requirements, a ready-made solution may be enough. But if the window has an unusual shape, if you want to cover a whole wall, or if you are looking for a fabric that doesn’t exist ready-made, made-to-measure stops being a luxury and becomes the only way to get the right result.
Can I combine two different fabrics on the same window?
Yes — that is precisely the logic behind the double-layer solution (voile/linen + blackout), and it is one of the most requested combinations in made-to-measure projects.
In short
Choosing the right curtain for the bedroom means balancing four decisions: the fabric (how it filters light and how it behaves over time), the colour (how it relates to the rest of the bedroom), the function (blackout, privacy, or both) and the measurements (how it fits the space exactly). There is no universal answer — there is the right answer for your space, your sleep climate and the style that already exists around the window.
