Ever walked into a room and thought, “Wow, this feels so much bigger than it actually is”?

Chances are, it wasn’t magic. It was clever interior design.

While furniture placement and lighting certainly play their part, your window dressings can have a surprisingly big impact on how spacious a room feels. The colour of your curtains, in particular, can completely change the perception of a space, making it feel brighter, airier, and far more open.

The good news? You don’t need to knock down walls or move house. Sometimes, a simple switch to the right made-to-measure curtains or Roman blinds can make all the difference.

Let’s take a look at the colours that can help your room feel bigger and brighter.

Why Curtain Colour Matters

Think of curtains as the frame around your room.

Just as the right frame can make a painting stand out, the right curtain colour can influence how large or small a room feels. Certain shades reflect light, blur visual boundaries, and create a sense of openness, while darker colours can make walls appear closer together.

That doesn’t mean dark curtains are always a bad idea, but if your goal is to maximise space, colour becomes an important consideration.

White Curtains: The Classic Space Enhancer

If there was an Olympic event for making rooms feel bigger, white curtains would probably take home the gold medal.

White reflects the most light, helping to brighten every corner of the room. This creates an airy atmosphere and makes walls seem to stretch further away.

White made-to-measure curtains work particularly well in:

• Small living rooms
• Compact bedrooms
• Apartments
• Home offices
• North-facing rooms

The result is fresh, timeless, and effortlessly elegant.

Soft Neutrals Are Your Best Friend

Not everyone wants brilliant white curtains, and that’s perfectly fine.

Soft neutral shades offer many of the same benefits while adding warmth and character.

Popular choices include:

• Ivory
• Cream
• Oatmeal
• Warm beige
• Soft stone
• Light taupe

These colours help create a seamless flow between walls and window dressings, which can make the room feel less visually cluttered.

It’s a designer trick that’s surprisingly simple but incredibly effective.

Pale Grey Creates Modern Spaciousness

Grey has become one of the most popular interior colours of recent years, and for good reason.

Light grey curtains add subtle sophistication without overwhelming a space. They reflect plenty of natural light while introducing a little more depth than white or cream.

Paired with matching walls, pale grey Roman blinds or curtains can create a sleek, contemporary look that feels calm and spacious.

Sage Green Brings the Outdoors In

Looking for something with a little more personality?

Soft sage green has become a favourite among homeowners who want colour without sacrificing brightness.

Inspired by nature, sage reflects light beautifully while creating a relaxing atmosphere. It works particularly well when paired with natural materials such as wood, linen, and woven textures.

The result is a room that feels fresh, calming, and wonderfully open.

Duck Egg Blue for Light and Airiness

Few colours feel as effortlessly uplifting as duck egg blue.

This soft, muted shade helps bounce natural light around the room while creating a gentle sense of tranquillity. It’s particularly effective in bedrooms, sitting rooms, and coastal-inspired interiors.

Whether you choose Roman blinds or flowing made-to-measure curtains, duck egg blue can instantly make a room feel lighter and more spacious.

Should Curtains Match the Walls?

Here’s one of the simplest tricks interior designers use.

When curtains closely match the wall colour, the eye naturally travels across the room without interruption. This creates the illusion of more space because there are fewer visual breaks.

For example:

• Cream walls with cream curtains
• Pale grey walls with pale grey curtains
• Soft beige walls with oatmeal curtains

The effect is subtle but incredibly powerful.

Floor-to-Ceiling Curtains Create Height

Colour isn’t the only factor.

The way curtains are hung can dramatically affect how large a room feels.

Installing made-to-measure curtains from ceiling height rather than directly above the window draws the eye upward, making ceilings appear taller and rooms feel larger.

Think of it as giving your room a pair of high heels.

Don’t Forget Roman Blinds

If your room is particularly compact, Roman blinds can be a fantastic alternative to curtains.

Because they sit neatly within the window recess, they take up less visual space while still providing softness and style.

Light-coloured Roman blinds in shades such as:

• Ivory
• Stone
• Soft grey
• Sage green

can help maximise natural light while keeping the room feeling uncluttered.

Colours to Use Carefully

That doesn’t mean darker colours are off-limits.

Deep navy, charcoal, forest green, and rich burgundy can all look stunning. However, in smaller rooms, they tend to absorb light rather than reflect it.

If you’re determined to embrace darker shades, consider balancing them with:

• Light walls
• Large mirrors
• Plenty of natural light
• Metallic accents
• Lighter flooring

Used thoughtfully, dark curtains can add drama without making a room feel cramped.

The Secret Is Balance

When it comes to making a room look bigger, there isn’t a single perfect colour. Instead, it’s about creating balance between light, colour, texture, and proportion.

For most homes, lighter shades such as white, cream, beige, pale grey, sage green, and duck egg blue tend to deliver the best results.

Pair those colours with expertly fitted made-to-measure curtains or elegant Roman blinds, and you’ll create a room that feels brighter, more spacious, and far more inviting.

And that’s a lot easier than knocking through a wall.
