If you’re searching for ways to keep light out of your home, you’ve probably come across terms like room darkening shades and blackout shades. While they sound similar, they offer different levels of light control, privacy, and comfort.
Whether you’re designing a better sleep environment, reducing glare in a media room, or creating a more comfortable atmosphere throughout your home, understanding the difference between room darkening and blackout window treatments will help you choose the right solution.
Explore our complete collection of room darkening window treatment solutions to see what’s possible.
What Are Room Darkening Shades?
Room darkening shades are designed to significantly reduce incoming light while creating privacy and comfort. They do not completely eliminate all light, but they can make a room noticeably darker throughout the day. Most room darkening window treatments use opaque fabrics or room darkening liners to block a large percentage of sunlight. However, small amounts of light may still enter around the edges of the shade. These are known as light gaps.

Room darkening shades are among the most popular choices for bedrooms, nurseries, family rooms, and home offices where glare reduction and privacy are important.
What Are Blackout Shades?
Blackout shades take light control a step further. These shades are designed to block nearly all incoming light, creating an ideal environment for sleep, movie watching, shift workers, or anyone sensitive to light. The biggest difference between room darkening and blackout shades is how they address side light gaps. Even the darkest fabric can allow light to enter around the edges if there is no system in place to block it.

Hunter Douglas solved this challenge with the innovative LightLock™ system available on Duette® Honeycomb Shades. Special side channels absorb and redirect light to help create one of the darkest environments available for residential window coverings.
Room Darkening vs Blackout Shades
Many homeowners use these terms interchangeably, but there are important differences.
- Room Darkening: Significantly reduces incoming light while maintaining privacy.
- Blackout: Blocks nearly all incoming light for maximum darkness.
- Room Darkening: Ideal for living rooms, offices, and many bedrooms.
- Blackout: Ideal for bedrooms, nurseries, media rooms, and shift workers.
- Room Darkening: May still have visible side light gaps.
- Blackout: Often uses side channels or specialized systems to eliminate light gaps.
What Are Light Gaps?
Light gaps are the small amounts of sunlight that can appear around the edges of a shade. These gaps occur because most shades must have slight clearance between the fabric and the window frame in order to operate smoothly. For many homeowners, room darkening shades provide plenty of darkness. But if you’re trying to create a true blackout environment, especially in a bedroom, those small gaps can become noticeable.

Layering shades with drapery panels is one way to reduce side light. Another option is choosing a blackout system specifically designed to address those gaps.
Best Blackout Shades for Bedrooms
One of the most common searches we see is homeowners looking for the best shades for bedrooms. The right solution depends on how dark you want the room to be.
- Duette® Honeycomb Shades with LightLock™ for maximum darkness.
- Designer Roller Shades with blackout fabrics.
- Roman Shades with room darkening or blackout liners.
- Dual Shades for daytime light filtering and nighttime blackout control.
Bedrooms often benefit from a combination of privacy, energy efficiency, and light control, making honeycomb shades one of the most popular choices.
Dual Shades: A Little Bit of Both
What if you want soft daylight during the day but darkness at night? That’s where dual shades shine. These innovative systems combine two shades into one treatment.

A light-filtering front shade softens incoming sunlight while preserving the atmosphere of the room. When additional privacy or darkness is needed, a secondary room darkening or blackout shade lowers independently. Dual shades are especially popular in bedrooms, guest rooms, and multi-purpose spaces where lighting needs change throughout the day.
Can Motorized Shades Be Blackout?
Absolutely. Many room darkening and blackout shades can be paired with motorization, allowing you to adjust them with a remote, smartphone app, or voice command. Motorized blackout shades are especially helpful for large windows, hard-to-reach windows, and bedrooms where scheduled adjustments can improve comfort and sleep routines.
Which Option Is Right for Your Home?
The choice between room darkening and blackout shades depends on your lifestyle, sleep habits, privacy needs, and how you use each room. Many homeowners discover that room darkening shades provide the perfect balance of privacy and natural light. Others prefer blackout shades in bedrooms where complete darkness creates a more restful environment.
