What Makes S Fold Curtains Different from Other Curtain Styles?

S fold curtains have become the default in new condos and freshly renovated HDB flats across Singapore. Before you commit, it helps to see how they actually differ from the older styles most homes grew up with: pinch pleat, eyelet, and pencil pleat. This guide compares them in plain terms so you can judge whether the look, the upkeep, and the price fit your home. If you already know S fold is what you want, you can head straight to our custom S fold curtains in Singapore page for fabrics and measurement.

What are S fold curtains?

S fold curtains hang from a track, not a rod. Runners spaced evenly along the track hold the fabric so it falls in a soft, repeating S-shaped wave from ceiling to floor. The wave is built into the heading tape and the runner spacing, which is why the folds stay even every time you open and close the curtain.

You will also see this style sold as S wave, wave fold, or ripple fold curtains. They describe the same thing under different regional names. Singapore and Australia say S fold, the UK says S wave, and North America says ripple fold. Our full S fold and S wave curtain range covers all of them.

S fold vs pinch pleat vs eyelet

The quickest way to see the difference is side by side.

Style	How the fold is made	Look	Hangs on	Best for
S fold	Track runners hold an even, continuous wave	Clean, modern, uniform	Track only	Condos, renovated HDB, minimalist interiors
Pinch pleat	Fabric gathered and sewn into pleats at the top	Structured, classic, formal	Track or rod	Traditional or luxe interiors
Eyelet (grommet)	Metal rings threaded onto a rod	Casual, wavy but uneven	Rod only	Budget rooms, quick installs

 

The core difference: an S fold curtain holds its shape from the track, so the wave repeats evenly on its own. A pinch pleat holds its shape from stitching sewn into the fabric. An eyelet curtain relies on the rings sliding on a rod, so the folds fall wherever they land.

The differences that matter day to day

Operation

S fold panels glide along the track with a light pull, and larger runs can be motorised. There are no rings to snag and no rod to bind against. For a wide living-room window or a balcony door you open every day, that smoothness is the feature you notice most.

Fullness and finish

Because the fabric is not gathered tight at the top, an S fold curtain shows off more of the material and drapes with a fuller, more finished face. That fullness is what gives the style its soft, upmarket look in photos and in person.

Space saving

When drawn open, S fold curtains stack back into a neat, compact bundle at one side. In smaller HDB rooms where every centimetre counts, that tidy stack keeps more of the glass clear and the room feeling open.

Cleaning

The panels stay on the track for routine care. A light vacuum with a brush head handles dust, and most fabrics only need occasional professional cleaning. You are not unhooking rings or wrestling a rod each time.

Light and heat control

Singapore sun is relentless, so fabric choice does the heavy lifting here. A dense or blackout-lined S fold curtain cuts glare and lowers heat gain through the glass, which eases the load on your aircon. Sheer S fold curtains soften the light while keeping the view.

Noise reduction

Heavier S fold fabrics absorb some of the noise bouncing around a room and soften sound from outside. If quiet is a priority, for a bedroom facing a main road or an MRT line, look at our acoustic curtains, which use denser, tightly woven fabric for stronger sound absorption.

Privacy

With the right fabric, S fold curtains give full privacy after dark, and you can pair a sheer day layer with a blackout night layer on a double track for both.

Fabric, sizes, and styles

Because the style is made to measure, S fold curtains come in sheer, textured, dimout, and blackout fabrics, in almost any colour, sized to your exact window run. You can see the full made-to-measure options on our custom curtains page.

Cost

Here is the honest part. S fold curtains use more fabric than a flat or eyelet panel because the wave needs extra width, usually two to three times the track length. So they are not the cheapest option upfront. What you pay for is the finish, the smooth operation, and a look that suits modern interiors, which is why most new homes still choose them.
