Difference Between Room Darkening And Blackout Curtains
The choice of the curtains is not just about getting the right fabric or color for it. You need to get the right option that matches your furniture and the overall interior theme setting. A curtain will determine how much light is going to enter your space and how it’s going to affect your overall sleep. This is why you need a room-darkening and blackout curtain solution. Most people would often use these terms as the same, but they are not. Both do help to reduce the incoming light, but they offer different levels of darkness for your place.
You need to understand the difference between room darkening and blackout curtains. Today we will explain this difference in detail.
What Are Room Darkening Curtains?

A room-darkening window curtain is designed to help prevent the inflow of even the tiniest light inside. Their fabric is tightly woven or has a treated coating that prevents the light penetration. These are ideal for use in living rooms, dining rooms, and bedrooms where you need to prevent the harsh inflow of sunlight.
What Are Blackout Curtains?
A blackout curtain is a product that will block almost all light into your interior space. This is made possible by its dense fabric with a special backing that prevents the light entering through the curtain’s material. Light can still leak through the edges, like top side or the bottom. You can achieve maximum darkness by getting wide enough curtain panels.
Room Darkening vs Blackout Curtains The Main Difference
The simplest way to understand the difference between these two drapes is that room darkening drapes reduce light, while blackout curtains block the light. By this, you don’t have to think that a room darkening drapery is anyway inferior, they just serve a different purpose.
Which Curtains Are Better For Bedrooms
Bedrooms happen to be one of the common places where you need curtains. If you like to wake up in the morning with sunlight in the room, these drapes might be perfect for you. They will help reduce that early morning harshness of the sunlight while letting some of the daylight into your room. Blackout drapes are ideal for when you need complete light control. They will be perfect for people who have to sleep in the daytime due to their night shifts. These blackout drapes will also prevent any glare from street lights during the night.
What About Living Rooms?
Room darkening window coverings are a practical choice for living rooms. Most people don’t want their living room to be completely dark during the day. Instead, they wish for a simple glare control and have less sunlight brightness. Room darkening draperies with their medium-dense fabrics will provide this functionality.
Blackout Curtains Aren’t Just About Darkness
Among the many misconceptions about blackout coverings is that they are useful when you need the room to be completely dark. The dense build of these drapes offers multiple benefits like less sun glare, better privacy, and a limited amount of solar heat entering via windows. But you don’t have to assume the fact that each blackout drapery will make your room cooler.
Does Curtain Color Matter?
Yes, the color of the curtains matters a lot. Dark colored and heavily woven fabrics will offer better light control, but the color won’t determine the fact that the curtain is blackout or not. A light color curtain can also be a blackout option but with a blackout lining. This is why the construction of the curtain matters more than its appearance.
Installation Makes A Big Difference
Even if you have a high-quality blackout curtain, it will not offer complete darkness if there are large gaps around the window. For better results, your curtain must extend on either side of the window. Wider panels will prevent the light entering from the edges, while overlapping curtain panels will prevent a bright line from appearing in the middle. A ceiling-mounted track will help reduce the gap above your curtains. The best option for these drapes is the ceiling-mounted track system, which will help reduce the gap above your curtain. For a light-sensitive room, we recommend getting a curtain fitting with options like a curtain box, pelmet, side channels, or a wraparound track. This will let you have greater window coverage.
Which One Should You Choose?
The right choice for these curtains will depend on how much light you actually need to control. You should choose a room darkening curtain if you wish to reduce sun glare, have soft daylight interior, better privacy, and some natural light during the day.
Blackout curtains are a better choice if you need maximum darkness, better light control, better bedroom conditions, and less screen glare. There is no set rule about choosing a single drapery. You can layer decorative drapery with a blackout lining or have sheers paired with blackout panels.
Final Thoughts
Room darkening and blackout curtains do look similar, but the light control is different. Room Darkening curtain are made to reduce brightness and offer a comfortable space. But with blackout draperies, you get much stronger light blocking. If you need a living room curtain for daylight control, you can get room darkening curtains as a practical choice. For a bedroom or other home spaces, you need serious light control. Before you buy, you have to consider not just the fabric but also the window size, the lining you will use, and the possible gaping around the fitting area. A well-fitted drapery will make a better difference than simply choosing the thickest fabric.
