Bedroom Blackout Blinds: How to Choose the Right Shade for Better Sleep

East- or west-facing bedrooms: An east-facing bedroom can get direct sunlight as early as 5 a.m. in summer, while a west-facing bedroom takes intense afternoon heat.

Both orientations need more than just light blocking — they also need thermal insulation, because a shade that stops light but lets heat through only solves half the problem. If the room also has floor-to-ceiling windows or multiple windows, the mounting method (inside vs. outside) becomes even more important.

Street-level or lower-floor bedrooms: Streetlights, signs, and commercial lighting create persistent light pollution, especially at night.

Both the fabric and the mounting method matter here — a high-performance blackout fabric paired with an outside mount minimizes edge light leakage as much as possible.

Bedrooms with daytime sleep needs: Night-shift workers, people who nap during the day, and nurseries all require a higher level of darkness than a typical bedroom, since the goal is to create near-nighttime conditions in broad daylight.

Motorized automation adds the most value here — scheduled opening and closing can match an irregular sleep rhythm without any manual effort.


Blackout Roller Shades have a clean, minimal profile. The fabric sits close to the window frame with smooth, simple operation.

They work best in standard-size windows where light blocking is the main concern and heat is not a major issue — for example, a quiet north-facing bedroom on an upper floor. 

SmartWings blackout roller shades start at $159.99 and are available in custom sizes.

For street-level bedrooms, pairing roller shades with an outside mount further reduces edge light gaps.

Blackout Cellular Shades add thermal insulation on top of light blocking. The honeycomb structure traps air inside the fabric, slowing heat transfer at the window.

For east- or west-facing bedrooms where light and heat are both problems, cellular shades are a better fit than roller shades. 

They also work well in nurseries and daytime sleep setups, where stable temperature helps maintain a comfortable sleep environment.

SmartWings cellular shades start at $179.

Zebra Shades switch between light filtering and light blocking by adjusting the alignment of alternating fabric strips. With the strips offset, soft light comes through. With the strips aligned, privacy and light blocking improve significantly.

Keep in mind that zebra shades do not reach the same blackout level as roller or cellular shades with blackout fabric — they are better suited for bedrooms where daytime lighting flexibility matters more than maximum darkness at night.

Many people pick the right blackout fabric but still notice light creeping in around the edges after installation. 

The fabric is usually fine — it is the mounting method that causes the gap.

Inside mount places the shade inside the window frame. It looks clean and does not take up wall space, but small gaps between the shade and the frame edges are unavoidable. 

For most bedrooms, this minor leakage is acceptable.

Outside mount places the shade on the wall surface beyond the window frame, so the shade coverage area is larger than the window itself. The edges sit against the wall, significantly reducing the path for light to enter.

Choose outside mount for the strongest blackout performance, inside mount for a cleaner look when absolute darkness is not critical. 

SmartWings products support both mounting methods — you select the one that fits your window during checkout.

Manual blackout shades solve one problem — blocking light. Motorized blackout shades improve the entire sleep routine.

Close shades without getting out of bed. When you are already lying down, a voice command or remote press closes the shades instantly.

SmartWings blackout shades work with Apple Home, Alexa, and Google Home for voice control. Apple Home requires a HomePod mini or Apple TV 4K as a Thread Border Router; Alexa and Google Home connect directly.

Wake up with natural light. Instead of an alarm jolting you awake, set your shades to open automatically before your wake-up time and let daylight do the work.

SmartWings supports timer and schedule controls, so you can set shades to rise at the same time every morning.

Switch to sleep mode fast during the day. Coming home from a night shift and need darkness right away — using a remote or smart home platform to close bedroom shades takes seconds, much faster than pulling each one by hand.

SmartWings shades support remote control operation, so even without a smart home platform, daily raising and lowering is easy.

SmartWings products are available in custom sizes with cordless motorized operation, making them safer for homes with children.

They support the Matter protocol and are compatible with Apple Home, Alexa, and Google Home. 

Zigbee and Z-Wave connectivity is also available for platforms like SmartThings, Home Assistant, Hubitat, and Homey.

Q1: Which blocks more light — blackout roller shades or blackout cellular shades?

Both use comparable blackout fabrics, so their light-blocking performance is similar. The main difference is that cellular shades also provide thermal insulation, making them a better fit when your bedroom has heat or cold issues at the window.

Q2: Does inside mount or outside mount block more light?

Outside mount blocks more light. The shade covers an area larger than the window frame, leaving less room for edge light leakage. If strong blackout performance matters to you, outside mount is the recommended option.

Q3: Do motorized blackout shades require wiring?

SmartWings motorized blackout shades run on battery power and require no wiring, making installation straightforward.
