Introduction
Choosing curtains isn’t just about colour or style. One of the most common areas of confusion for customers is the difference between blackout curtains and room darkening curtains. Although the terms sound similar, they serve very different purposes, and understanding the distinction is essential to making the right purchase.
What Are Blackout Curtains?
Blackout curtains are specifically designed to block out external light as completely as possible. This is usually achieved through a specialist blackout lining or coating applied to the reverse of the fabric. When fitted correctly, blackout curtains can block close to 100% of incoming light.
They are most commonly used in bedrooms, nurseries, and home cinema rooms, where controlling light levels is a priority. Beyond light control, blackout linings also add insulation, helping to keep rooms warmer in winter and cooler in summer.

What Are Room Darkening Curtains?
Room darkening curtains reduce light rather than eliminate it entirely. They are typically made from heavier or tightly woven fabrics that soften daylight and reduce glare while still allowing some light to pass through.
These curtains are ideal for living rooms, dining areas, or shared spaces where complete darkness would feel too harsh. They offer privacy and comfort without making a room feel closed off.

Key Differences Between Blackout and Room Darkening Curtains
The main difference lies in performance. Blackout curtains aim to eliminate light, while room darkening curtains simply reduce it. Blackout curtains tend to be heavier and more structured due to their lining, whereas room darkening curtains often drape more softly.
Light Scale
Our Enhanced Living ranges, use a 1–5 light control scale to clearly indicate performance. On this scale, 5 denotes blackout curtains, while 4 represents room darkening.
This makes it easier for customers to understand exactly how much light a product will block and compare options across a range. Looking for a stated light rating can help avoid confusion and ensure the right curtain is chosen for each room.
Which Rooms Suit Each Type Best?
Bedrooms and nurseries benefit most from blackout curtains, particularly for improving sleep quality. Living rooms and dining areas are better suited to room darkening curtains, which maintain a brighter, more welcoming atmosphere.
Common Buying Mistakes to Avoid
A common mistake is assuming that thicker fabric automatically means blackout performance. Installation is also crucial—light can still enter around the edges if curtains are too narrow or poorly fitted.
Final Buying Advice
Understanding how blackout and room darkening curtains differ helps customers choose confidently. Matching the curtain type to the room’s purpose ensures satisfaction and reduces the likelihood of returns.
