Which Curtain to Choose for a Patio Door: Dimensions, Heat and Fitting
A patio-door curtain is chosen on three challenges specific to large glazed surfaces: dimensions, because the curtain must cover a wide opening without looking skimpy, heat, because an exposed patio door captures strong solar radiation, and fitting, especially in front of a sliding door. A made-to-measure wide curtain, dense and thermal, answers all three. The Kurtens curtain, at 620 gsm, holds back up to 7 °C of difference*, blocks 100% of light* and is cut to the exact dimensions of the patio door.
To choose well, start from your patio door: its width, its exposure, and the type of opening (hinged or sliding).
Dimensions: the first challenge of a patio door
A patio door is wide, often 2 to 4 metres. A standard-size curtain looks skimpy there and leaves gaps on the sides. Made-to-measure wide is essential here: the curtain should extend 15 to 20 cm beyond the door on each side and reach the floor to cover the whole surface. This fullness guarantees blackout, insulation and a refined drape. Discover the custom extra-wide curtains collection.
Table: which curtain for your patio door
Here are the challenges of a patio door and the suitable answer.
| Challenge | What you need | Kurtens answer |
|---|---|---|
| Large width | Made-to-measure, generous overlaps | Cut to exact dimensions, to the floor |
| Overheating in summer | Thermal insulation at the glass | Up to 7 °C of difference* |
| Blackout (TV, studio living room) | Dense opaque fabric | 100% of light blocked* |
| Sliding patio door | Fitting that clears the opening | Wide rod, curtain that fully draws aside |
*Data obtained under optimal test conditions. Real performance depends on exposure, glazing and fitting.
Heat: a patio door captures strong radiation
A large glazed surface facing south or west captures a great deal of solar radiation and turns the living room into a furnace in summer. It is often the number-one problem of a patio door. A dense thermal curtain, closed during the hot hours, blocks that radiation before it heats the room. The Kurtens curtain holds back up to 7 °C of difference*.

The sliding patio door: fitting to anticipate
In front of a sliding patio door, the curtain must not hinder the opening. The rod is fitted wide enough that the curtain, once open, fully clears the passage and does not block the leaf. You also plan a height that grazes the floor without dragging, so as not to impede the slide. A made-to-measure curtain lets you adjust width and height precisely to this type of opening, which a standard curtain cannot.
The right patio-door curtain, made to measure
A successful patio-door curtain combines large width, thermal insulation and blackout on demand, fitted to clear the passage. The Kurtens curtain brings these qualities together: dense at 620 gsm, it holds back up to 7 °C of difference*, blocks 100% of light* and is cut to the exact dimensions of the patio door, with the recommended overlaps. It is the weight that makes the insulation and blackout, as our guide on how to choose curtain weight explains. Configure yours in the made-to-measure patio curtains collection.
Sizing the patio-door curtain
On a patio door, the slightest sizing flaw shows: a curtain that is too narrow lets light and heat in on the sides, one that is too short loses insulation and breaks the look. Made-to-measure, with a width that extends 15 to 20 cm beyond the door on each side and a height to the floor, guarantees full coverage. Compare the functions in the custom curtains collection.
Frequently asked questions
What curtain width for a patio door?
The curtain should extend 15 to 20 cm beyond the door on each side to cover the whole surface and avoid light and heat leaks. On a patio door several metres wide, made-to-measure extra-wide is essential: a standard curtain looks skimpy and leaves gaps.
How do I stop a patio door from overheating in summer?
A dense thermal curtain, closed during the hot hours, blocks solar radiation before it heats the room. The Kurtens curtain holds back up to 7 °C of difference*. For a heavily exposed patio door, it is the simplest interior solution to set up with no building work.
How do I hang a curtain in front of a sliding patio door?
The rod is fitted wide enough that the curtain, once open, fully clears the passage without blocking the leaf. You plan a height that grazes the floor without dragging. Made-to-measure adjusts width and height precisely to this type of opening.
Can a patio-door curtain black out completely?
Yes, with a dense opaque fabric cut to exact dimensions. The Kurtens curtain blocks 100% of light* when closed, useful for a TV living room or a room to darken, provided the width covers the whole patio door with no side gaps.
Curtain or blind for a patio door?
The curtain covers a large width in one piece, dresses the room and insulates with a dense fabric, while fitting without heavy drilling. On a patio door, a made-to-measure wide curtain offers blackout, thermal insulation and a beautiful drape, where a blind is often limited to filtering light.
Key takeaways
A patio-door curtain is chosen on dimensions, heat and fitting. Made-to-measure extra-wide is essential to cover the whole door with no gaps; thermal insulation limits the overheating of a large glazed surface; fitting is anticipated in front of a sliding door. The Kurtens curtain, at 620 gsm, holds back up to 7 °C of difference*, blocks 100% of light* and is cut to the exact dimensions of the patio door.
