Practical Guide From A 25-year Curtain Designs Expert
With the advent of technology and modern architecture, curtain designs have evolved more rapidly in the last five years. This article provides clarity for homeowners making curtain choices in 2026.

Wisdom / Collection
Quick Answer
Modern architecture's shift towards larger spaces, wider windows, and sliding doors, combined with lifestyle, weather, and budget factors, is driving rapid changes in curtain design trends.
Modern architecture's emphasis on larger spaces favours wider windows and sliding doors that open to the outdoors, bringing higher ceilings (mostly over 10 feet) or even double volume living areas that create more natural light. These newer structures have brought, and continue to bring, necessary changes to soft furnishings.
Other influences such as practicality, weather considerations, lifestyle preference, and budgetary constraints are also key reasons why certain trends dominate.

Quick Answer
The wave pleat (also known as ripple fold curtains) is the top curtain design choice for 2026. It delivers a premium look with minimal effort through clean S-shaped folds, elegant silhouette, and excellent stacking efficiency.
The wave pleat remains the top curtain design choice. When executed properly, the clean wave lines project high-end simplicity and understated elegance. It requires fuller portions of fabric, normally 2.5 times the width of the area to be covered.
Why Wave Pleat Stands Out
Wave pleat curtains are the top choice for contemporary interiors. Their appeal:
This design delivers a premium look with minimal effort. Whereas many pleat styles feel bulky or overly traditional, wave pleats offer the perfect balance of softness and structure.
Track & Motorized Systems
Since the 2024 trend review, more reliable curtain track systems supporting wave pleats have continued to emerge. Motorized and manual systems both support the wave pleat well. The current standard uses up to 2.5x fabric volume for a fuller fold, an improvement over earlier versions that appeared flat at 2x volume.
Modernizing Traditional Pleats to Achieve Sleeker Looks
Double pleats, Singapore pleats, and French pleats can undergo a heated pleating treatment to fix fall lines for a sleek, modern feel. Test a small portion first as the treatment may affect heat-sensitive textiles.
Quick Answer
Yes, double pleats and French pleats are not fading away. With heat-simulated fixed pleating technology, these traditional styles can achieve a sleek, modern look that complements minimalist interiors.
The latest modern minimalist look has plenty of fabrics that complement modern living spaces with these styles. In-trend fabrics with heat-simulated fixed pleating can more than make up for the less-full look.

The Wave Pleat remains the top curtain design choice for living rooms and dining rooms, usable as a single or double layer. Some homes may not have sufficient recessed pelmet space (around 14 inches) for a double wave pleat setup.
Solution for Limited Pelmet Space
Use the wave pleat at the front (facing the room) and the New York pleat behind it for privacy. The New York pleat is a single pleated curtain on a universal track. This combination uses only 7-8 inches of pelmet room, which is standard in most homes today.

Quick Answer
This season leans towards a soft, muted palette: champagne beige, sandstone neutrals, latte cream, olive green, muted navy, warm grey taupe, and caramel brown, paired with linen-blend textures and organic slub finishes.
These colours and textures integrate seamlessly with Japandi, Scandinavian, modern luxe, and contemporary Asian interiors. Linen look or linen feel textures project luxury and soft, flowy interiors, making them the most requested look for the season.

Quick Answer
Place the day curtain at the front (facing the room) and the dim-out or blackout at the back, closer to the glass. Choose a contrast colour for a bold look, or a close-matching colour for a subtle, seamless finish.
The day curtain should face the room, with the dim out closer to the glass window or sliding door. For contrast, choose a different colour for the back layer. For a subtler look, match it closely to the day curtain colour.
Dim Out Collections (80-90% darkening)

Lights Out / Collection
A sheer wave pleat that stacks well, combining beauty, practicality, and durability.
A Word of Caution
When placing day curtains at the front, keep in mind that the day curtain needs to be drawn aside first before accessing the black out / dim out / privacy layer behind it. This may feel less intuitive for users used to having the privacy layer at the front.
In conclusion, the wave pleat is set to continue its dominance in the modern curtains market.
With minimalist design, reduce visual lines as much as possible, especially from curtain tracks installed too low below the ceiling. Always maximise curtain height to create a sense of width and generous space indoors.

Quick Answer
Mounting your curtain track close to the ceiling and letting the curtains fall to the floor instantly makes any room feel taller and more spacious, even in smaller homes.
Going back over a century, curtain fabrication styles and fabric designs have evolved considerably, shifting from elaborate window treatments to the modern, in-trend styles used today. Sewing trends, fabric construction, fabric widths, and material types have all improved to address consumer demands for affordability, durability, and ease of maintenance.
Classic Pleat Styles
Window treatments evolved through many pleat types and fabric fullness variations, giving rise to double pleats (Dutch pleats), locally known in Malaysia as "Singapore Pleats". Other styles include double pencil pleats, eyelets, tab tops, box pleats, goblet pleat, bishop's sleeves, and wave pleats.
Shorter & Top Window Treatments
For shorter windows: Roman blinds, Austrian blinds, London blinds, and Japanese blinds, sometimes combined with curtains for a layered look. For more elaborate homes, curtain toppers such as quilted pelmets, swags, tails, and valances were used to achieve a European aristocratic feel.
