Many people assume that choosing "blackout" curtains automatically means their bedroom will become completely dark.
But after installation, many discover that light still leaks in around the edges—even with blackout curtains installed.
The issue usually isn't the product itself. It's the approach to light blocking.
Why Blackout Doesn't Mean 100% Darkness
In real home environments, blackout curtains don't guarantee 100% darkness.
Most blackout fabrics effectively block direct light, but whether your bedroom truly darkens depends more on:
Whether gaps exist between the curtain and window frame
Whether the installation creates complete coverage
In other words, light leakage typically comes from structure, not the fabric itself.
Common Reasons Your Bedroom Isn't Dark Enough
Side Light Leakage (Most Common)
Roller shades or cellular shades typically leave space during installation, creating light channels at the edges.
Installation Method Mismatch
Inside mount looks cleaner but allows more light leakage
Outside mount provides greater coverage and better light blocking
Window Frame Structure Issues
Uneven window frames or walls can also cause light leakage at the top or edges.
What Actually Works for Bedroom Blackout
If your goal is to get your bedroom as close to "pitch black" as possible, the key is combination, not a single product:
Blackout fabric + outside mount installation (reduces side leakage)
Blackout fabric + light blockers (covers edges)
Blackout fabric + side tracks (creates more complete sealing)
In practice, motorized blackout roller shades are the most common foundation, then optimize overall performance through installation methods.

Frequently Asked Questions About Blackout Curtains
Q1. Can blackout curtains make a room completely dark?
No—near-total darkness is more realistic due to structural gaps. SmartWings Blackout Roller Shades block up to 100% of light at the fabric level, but achieving pitch black requires combining with outside mount installation and edge solutions like light blockers.
Q2. Why do blackout curtains still leak light?
Light leaks through gaps at sides, top, or bottom—not the fabric. SmartWings offers light blockers and side track systems to seal these gaps for complete coverage.
Q3. Are roller shades or cellular shades better for bedroom blackout?
SmartWings Cellular Shades seal tighter with their honeycomb structure and add insulation. Blackout Roller Shades offer equal light blocking with more design flexibility.
Q4. How do I choose the right blackout curtains for my bedroom?
Match your needs: SmartWings Roller Shades for everyday use, Blackout Roller Shades for maximum darkness, or Cellular Shades for blackout plus energy efficiency. Combine with outside mount for best results.
Q5. Are motorized blackout curtains worth it?
Yes—SmartWings motorized options support voice control (Apple Home, Google, Alexa) and automated schedules. Available with battery, hardwired, or PoE power to fit any setup.
