Why standard curtains fall short for large windows.
For a large window, choose the fabric width according to the curtain pole, fullness and side coverage. Either one or two panels can work.
With two panels, an edge-to-edge closure may leave a gap in the centre: allow a suitable overlap. With one panel, also check coverage at the sides and bottom. Compare the fabric’s documented performance; fabric weight alone does not establish insulation.
| Criterion | One panel | Two panels |
|---|---|---|
| Coverage | Size the panel to cover the width, sides and bottom | Size both panels to cover the same opening |
| Centre closure | No join between two panels at the centre | Allow an overlap to avoid a gap at the centre |
| Opening | The fabric gathers on one side | The panels can gather on opposite sides |
| Weight to handle | The curtain’s weight is concentrated in one panel | The weight is divided between two panels |
| Installation and manufacture | Check the mounting, stack-back space and any joining seam | Check the mounting, stack-back space and overlap |
Kurtens 3-in-1 fabric: 620 g/m², 100% blackout, thermal gain of up to 7 °C measured in a laboratory. The number of panels alone cannot predict these performances. Results in use depend in particular on coverage and installation.
The sizes available at Kurtens.
Four standard sizes cover the most common configurations: 100x150 cm (classic window), 150x230 cm (tall window), 250x230 cm (large living room window) and 300x270 cm (full-height patio door). If your window matches none of these dimensions, the made-to-measure configurator lets you order to the exact centimetre.
270 cm is the width of the fabric roll, not an absolute maximum curtain height. The options depend on the combination of width and height. For dimensions not offered in the configurator, contact us to confirm production and whether a joining seam is needed.
The fabric is identical whatever the size ordered: 620 g/m², multi-layer, with the same thermal insulation performance (up to 7°C of gain*), blackout (100%) and noise reduction (22 dB*). Results in use depend on coverage and installation.
14 colors are available. See our color guide to choose according to your room.
Several finishes: eyelets, pencil pleat and rod pocket or multifunctional. For wide widths, eyelets ensure an even drape and easy handling. See our heading guide.
Mind the rod: a wide curtain is a heavy curtain.
For a dense curtain (up to 620 g/m²), a panel 300 cm wide and 270 cm high weighs around 5 kg. That is far heavier than a standard decorative curtain. The rod has to be up to it.
Use a sturdy wall-mounted rod, fixed with intermediate brackets every 100 to 120 cm. For a 300 cm curtain, that means at least 3 fixing points (one at each end, one in the centre). The fixings must suit your wall: expansion plugs for concrete, Molly bolts for plasterboard.
Telescopic rods are not recommended for wide widths. They risk bowing in the centre under the curtain's weight, which creates visible sagging and light leaks at the top.
For dimensions and installation advice, see our size guide.
Which windows need a wide-width curtain.
Living room patio doors are the most common case. A standard patio door is 200 to 300 cm wide and is the largest glazed surface in the home, so the main source of heat loss and outside noise. The choice between one and two panels depends on the opening, stack-back space and handling. For patio
doors, see our made-to-measure patio door curtain collection.
Double French doors (2 leaves) are generally 180 to 240 cm wide. The curtain hangs in front on a rod and does not get in the way of opening the leaves. It slides to the side when you open the door.
Panoramic windows, common in recent builds and architect-designed houses, can reach 300 cm wide or more. A made-to-measure curtain is often the only viable option at these dimensions.
Sliding doors work very well with a wide-width curtain. The curtain hangs in front of the door on a separate rod and does not block the sliding mechanism. For the thermal
insulation of large glazed surfaces, see also our made-to-measure thermal curtain collection.

Frequently asked questions.
What is the maximum width for a made-to-measure Kurtens curtain?
The largest standard size is 300x270 cm. Beyond that, the made-to-measure configurator lets you order to the exact dimensions of your window. For width, there is no fixed limit with made-to-measure.
Do I need one or two panels for a large window?
Either configuration can work. One panel avoids a central join but concentrates the weight to handle. Two panels divide that weight and can open to opposite sides; allow a central overlap.
Choose according to the opening, stack-back space, weight and mounting. Performance also depends on the fabric, coverage and installation.
Does a wide-width curtain need a special rod?
Yes. A dense technical curtain weighs up to 620 g/m². A 300 cm wide panel then weighs around 5 kg. The rod must be wall-mounted, sturdy, with intermediate brackets every 100 to 120 cm to prevent bowing. Telescopic rods are not recommended for wide widths. See our heading guide.
Does a wide-width curtain insulate as well as a standard curtain?
Yes. For a given model, the fabric and its performance are identical whatever the size (performance is measured per square metre, not per curtain). The 3-in-1 curtain, for example, keeps its 620 g/m², its 100% blackout*, its 7°C* and its 22 dB* whatever the width.
Does a wide-width curtain get in the way of opening a sliding door?
No. The curtain hangs on a wall-mounted rod in front of the door, not on the door itself. It slides on the rod independently of the door's mechanism. When you open the sliding door, you first push the curtain to the side, then slide the door as normal.
