A good night's sleep is essential, especially with bright summer nights or streetlights shining into your room. Perhaps you want to keep your living room cool during a heatwave. Blackout curtains are an effective solution. They provide not only darkness but also privacy and can help regulate room temperature.
As a Joybuy Product Recommendation Officer, I'm here to help you make the right choice. In this guide, we'll explore key factors to consider and highlight some of the top picks for 2026, based on their specifications and functionality.
What to Look for When Choosing Blackout Curtains
Before making a purchase, it's important to consider a few key aspects. The right window treatment depends on your room, your needs, and your windows.
Curtains vs. Roller Shades: Which Is Right for You?
The first decision is often between classic curtains and sleek roller shades.
- Curtains: These offer a soft, elegant ambiance and are available in a wide variety of fabrics and hanging styles (grommets, pleats). They can also contribute to sound insulation. A set of blackout curtains for the bedroom is a popular choice for creating a cozy atmosphere.
- Blackout Roller Shade: A roller shade provides a clean, modern look. It's an efficient, space-saving solution with a small footprint, ideal for smaller rooms, offices, or minimalist interiors.
Fabric is Everything: Opacity and Thermal Properties
Not all "blackout" curtains are created equal. The degree of light-blocking depends entirely on the fabric.
- Blackout Curtains: These are designed to block 95% to 100% of light. They often feature a special coating or are constructed with a dense, black inner layer using triple-weave technology.
- Dimout Curtains: These block a significant amount of light (typically 60-85%) but still allow a soft glow to filter through. They are perfect for darkening a room without making it pitch-black.
- Thermal Curtains: Many blackout fabrics also have thermal properties. They help keep heat in during the winter and block it out in the summer, which can contribute to a lower energy bill.
The Right Size and Hanging Style
For an optimal blackout effect, size is crucial. Ensure the curtains are wide and long enough to cover the entire window and frame, minimizing light gaps on the sides. While ready-made sizes are often sufficient, custom-made curtains can be a worthwhile investment for non-standard windows.

Frequently Asked Questions About Blackout Curtains
What is the difference between blackout and dimout?
Blackout curtains are designed to block almost all light (95-100%), making them ideal for bedrooms. Dimout curtains block a significant amount of light (usually 60-85%) but still let some filter through. This creates a dark, but not pitch-black, room, which can be pleasant in a living room or office.
Do thermal curtains really help with the energy bill?
Thermal curtains have an insulating effect. The dense fabric or special coating helps create a layer of still air in front of the window. This acts as a buffer: in the winter, it blocks cold air from the window and keeps warm air in, and in the summer, it helps keep the sun's heat out. This can contribute to a more stable room temperature and, consequently, lower heating or air conditioning usage.
How do I measure for the correct curtain size?
For proper coverage and a beautiful effect, follow these steps:
- Width: Measure the width of your curtain track or rod. Multiply this measurement by 1.5 to 2.5, depending on the fullness you desire. More fabric creates a richer, more luxurious look.
- Length: Measure from the top of the track (or the bottom of the rings on a rod) to where you want the curtains to end. This could be the windowsill, just below the sill, or all the way to the floor. Ensure the curtains are wide and long enough to prevent light gaps.
