Curtains transform a room before any piece of furniture: they filter light, absorb noise and set the character of the space. However, choosing them badly produces the opposite effect to the one intended, with stiff hangs, fabrics that yellow or a blown budget. This guide brings together useful criteria for choosing them sensibly, without relying on passing trends.
Start with function, not colour
Before looking at catalogues, it is worth answering a simple question: what should the curtain do? In an east-facing bedroom, the goal is to block the morning light; in a living room with a south-facing picture window, it is better to regulate the incoming sunlight without losing brightness. A densely draping fabric with a blackout lining solves the first case, while a washed linen or a cotton gauze works better in the second. For damp rooms, such as bathrooms or kitchens, prioritise treated fibres or quick-drying polyester.
Width matters more than length
A common mistake is to measure only the window. The curtain should cover the opening and extend 15 to 20 cm on each side, so that when gathered it does not cover the glass. As for volume, the usual rule is to double the width of the track: a 150 cm window needs about 300 cm of fabric to form harmonious pleats. If you want a calmer effect, 1.5 times the width is enough. The length depends on taste: floor-length adds elegance, while mid-height is more practical in walk-through areas.
Fabrics: the pros and cons of each option
- Linen and blends: natural texture and good drape; it creases easily and is best washed cold.
- Cotton: breathable and easy to dye; it may shrink after the first wash.
- Polyester: resistant, economical and barely loses its shape; the feel gives away its origin if it is low density.
- Velvet: acoustic and thermal insulation; it collects dust and requires frequent vacuuming.
- Gauze and voile: diffused light without giving up privacy; low opacity.
Combining two layers —a light base and another with a lining— offers flexibility throughout the year and allows privacy to be adjusted according to the time of day.
Installation systems
A concealed ceiling track comes into its own in high ceilings and minimalist settings. A visible rod, on the other hand, accommodates rings and decorative finials, which is useful when the wall allows it. For small windows or sloped ceilings, sliding Japanese panels bring visual order. Before buying, check the weight of the fabric: a thick fabric requires reinforced brackets and anchors suited to the type of wall.
Maintenance that extends useful life
Vacuuming regularly and shaking them outdoors every few months prevents dust from becoming embedded in the fibres. Follow the label instructions: many lined fabrics are not machine-washable and call for dry cleaning. Ironing on the reverse at medium temperature, and avoiding prolonged exposure to direct sunlight, will help preserve the colour. Storing seasonal curtains rolled rather than folded prevents marks that are difficult to remove.
In short, a well-chosen curtain is born from three decisions: what the room needs, how much fabric the opening requires and which fibre suits daily use. The rest —colour, pattern, finish— comes later, once the foundation works.
