10 Living Room Curtain Ideas for 90 x 90 Windows: Practical & Stylish Curtain Inspirations for Square Living Rooms

Over my 10+ years as an interior designer, I’ve seen how a well-chosen curtain can transform a square-shaped living room. Current design trends lean toward light, airy fabrics and layered textures, and when you’re working with a 90 x 90 window, small-space principles really shine. Small dimensions encourage creativity – I’ve often found that you end up with more personalized, bespoke solutions than in bigger rooms. Today, I’ll share 10 living room curtain ideas for 90 x 90 windows, blending my own project experience with data-backed design insights.

Minimalist Sheer Panels

My Take: In one compact flat I worked on, sheer white panels instantly made the living room feel taller and more open. They subtly blur the edges of a square window, making it feel wider.

Pros: Enhances natural light, perfect for layering with blackout blinds; great for small living room curtain ideas according to Architectural Digest’s 2023 trend report.

Cons: Doesn’t offer full privacy at night unless paired with another layer.

Tip: For easy reference, I’ve used minimalist kitchen storage designs as inspiration for clean lines and clutter-free looks, applying the same discipline to curtain styling.

Layered Linen with Blackout Lining

My Take: Linen has a beautiful drape, and adding a blackout lining lets my clients enjoy lazy weekend sleep-ins without sacrificing style.

Pros: Combines aesthetic appeal with functional light control; ideal for living rooms that double as guest spaces.

Cons: Linen can wrinkle easily, so it’s not for those who dislike a relaxed look.

Cost Factor: Expect to invest a bit more for quality natural fabrics and custom lining.

Ceiling-to-Floor Drapery

My Take: Extending curtains from ceiling to floor makes even a square and modestly sized window appear grander. I first tried this trick in a studio apartment, and the change was dramatic.

Pros: Visually elongates walls; creates a sense of luxury; works with both classic and modern interiors.

Cons: Requires precise measuring; mistakes are costly with full-length fabric.

Textured Weaves

My Take: I once used a slightly nubby cotton blend in a client’s reading nook – the texture caught the light beautifully.

Pros: Adds depth and tactile interest without busy patterns; ideal for neutral schemes.

Cons: Some weaves are harder to clean and may trap dust.

Bold Geometric Prints

My Take: In a retro-inspired project, I paired a mustard yellow sofa with navy geometric curtains – the square window became a feature.

Pros: Adds personality; can tie disparate room colors together; per Color Marketing Group, bold prints are trending in urban spaces.

Cons: Can overwhelm a very small room if patterns are too dense.

Case Note: This worked well because furniture and wall colors were kept simple, letting the pattern shine.

Roman Shades with Side Panels

My Take: Combining the clean look of Roman shades with decorative side panels gives you versatility – I love this for compact layouts that need flexible light control.

Pros: Practical for daily use; panels soften and frame the window; good for square living rooms where space is premium.

Cons: Installation is slightly more complex, involving two systems.

Idea Boost: This approach reminded me of how a L-shaped kitchen layout frees more counter space – it’s about combining functions smartly.

Two-Tone Color Blocking

My Take: I’ve used a dark base color with a lighter top portion to make a tall statement without overpowering the room.

Pros: Creates visual interest; can subtly alter proportion perceptions of a square window.

Cons: Requires custom sewing or a skilled tailor to execute well.

Metallic Thread Accents

My Take: For a festive seasonal makeover, metallic threads catch lamplight and sunlight alike – an easy way to lift a small space.

Pros: Adds shimmer without gaudiness; great for evening ambience.

Cons: Specialty fabrics may be harder to source.

Ripple Fold Curtains

My Take: I love ripple folds for their uniform wave – they look tailored yet relaxed, especially in light neutral tones.

Pros: Glides smoothly on tracks; contemporary look that works in many styles, from Scandinavian to coastal.

Cons: Needs custom track systems; not ideal if you change decor often.

Natural Bamboo Shades

My Take: In one airy loft, bamboo brought warmth and texture, balancing sleek modern furniture.

Pros: Sustainable material; filters light beautifully; according to Houzz, natural materials are on the rise for 2024.

Cons: Limited blackout capability.

Pairing Tip: Works beautifully with warm wood elements in the surrounding decor for a cohesive look.
