Choosing bedroom window coverings can feel simple at first, until you realize how much the right curtains affect comfort, privacy, light control, and even room temperature. If you are researching how to choose blackout curtains, the best approach is to look beyond colour and style alone. Fabric, lining, installation method, and accurate measurements all play a major role in how well blackout curtains perform.
For Canadian homeowners, blackout curtains can be especially useful in bedrooms where early summer sun, streetlights, neighbouring homes, or seasonal temperature swings make restful sleep more difficult. The good news is that once you understand the basics, it becomes much easier to compare options and choose a solution that suits your space. Below, we break down the key details to help you find blackout curtains for better sleep without sacrificing function or design.
Why blackout curtains matter in a bedroom
Bedrooms need a different level of light control than most other rooms. While a living room may benefit from filtered daylight, a bedroom often needs deeper darkness for sleeping, shift work, children’s naps, or a more relaxing atmosphere in the evening. Blackout curtains are designed to reduce incoming light far more effectively than standard drapery panels.
They can also support privacy and help moderate indoor temperatures by adding another layer at the window. In many homes, that makes them a practical option, not just a decorative one.

How to choose blackout curtains based on fabric
When homeowners search for the best blackout curtains for bedroom spaces, fabric is usually one of the first things they notice. It affects how the curtains hang, how heavy they feel, how formal or casual they look, and how much light they can block when paired with the right lining.
Common blackout curtain fabric types
There is no single best fabric for every bedroom. Instead, think about performance, maintenance, and appearance together.
- Polyester blends: A common choice because they are durable, easy to maintain, and available in many colours and textures. They can work well in family homes and everyday bedrooms.
- Velvet or velour: Heavier fabrics that often create a fuller, more luxurious look. Their weight can help improve light blocking and insulation when properly lined.
- Cotton blends: Popular for a softer, more casual finish. On their own, cotton curtains are not usually enough for blackout performance, but with the right lining they can be effective.
- Linen-look fabrics: These offer a relaxed, airy appearance that many homeowners like, though true blackout performance depends heavily on the backing or lining rather than the face fabric alone.
In general, heavier and more tightly woven fabrics tend to perform better than thin, loosely woven ones. Still, the lining often matters just as much as the front fabric. A beautiful fabric with inadequate backing may let in more light than expected.
What to look for in bedroom fabric selection
As you compare blackout curtain fabric types, ask yourself:
- Do you want a soft, casual look or a more tailored, formal finish?
- Will the curtains be opened and closed daily?
- Is easy maintenance important in the room?
- Do you want the curtains to visually warm up the bedroom?
- Will the fabric coordinate with bedding, wall colour, and flooring?
For many Canadian homes, a medium-to-heavy fabric with a good drape strikes the right balance between function and style.
Understanding blackout curtain lining options
If fabric is the face of the curtain, the lining is the performance layer behind it. Blackout curtain lining options can make a major difference in light control, insulation, and overall finish.
Main types of lining to consider
- Standard blackout lining: Designed to significantly reduce incoming light. This is a common choice for bedrooms where darkness is the main priority.
- Room-darkening lining: Useful when you want noticeable light reduction but not complete blackout conditions. This may be enough in some bedrooms, but not all.
- Thermal or energy-conscious lining: Can help support insulation and improve comfort near windows, especially in homes with stronger seasonal temperature shifts.
- Foam-backed or coated blackout materials: Often used to increase light blocking. Performance can vary depending on quality and installation.
When reviewing blackout curtain lining options, it helps to think about your bedroom’s specific challenges. A child’s room facing east may need stronger light blocking than a guest room used only occasionally. A primary bedroom with large windows may benefit from energy efficient blackout curtains that can support comfort during both winter and summer.
Lining details that affect results
Even with a blackout lining, curtains may still allow some light around the edges, top, or bottom. That is why fit and installation are just as important as material choice. In many bedrooms, homeowners assume the fabric is the issue when the real problem is that the curtain rod is too narrow or the panel coverage is too shallow.

How fit affects darkness, privacy, and comfort
One of the most overlooked parts of how to choose blackout curtains is fit. Even high-quality curtains will underperform if they are too narrow, too short, or mounted incorrectly.
Width: go wider than the window
For better light control, the curtain rod should usually extend beyond the window frame on both sides. This allows the panels to cover the window more fully and reduce side light gaps. As a general design rule, curtain panels should also have enough fullness to look substantial when closed rather than stretched flat across the opening.
If the panels are too narrow, they may technically cover the glass but still leave visible light along the edges. Wider coverage usually creates a better blackout effect and a more polished appearance.
Height: mount higher for better coverage
Installing the rod higher above the window can improve both style and performance. This helps reduce the gap at the top where light often enters. It can also make the room feel taller. For many bedrooms, mounting curtains closer to the ceiling or several inches above the frame works better than placing the rod directly at the top of the trim.
Length: avoid an awkward finish
For blackout curtains in a bedroom, full-length panels are often the most effective and visually balanced option. Depending on the look you want, curtains can lightly touch the floor or hover just above it. Panels that stop too high can feel unfinished and may let in more light than necessary.
How to measure for blackout curtains
Accurate measuring is one of the best ways to avoid disappointment. If you are wondering how to measure for blackout curtains, focus on the installed area, not just the glass size.
Simple measuring steps
- Measure the window width: Start from the outer edge of the frame to the other outer edge.
- Add space for coverage: Plan extra width beyond the frame on both sides so the curtains can overlap the opening and reduce light gaps.
- Measure the installation height: Decide where the rod will sit above the frame or near the ceiling.
- Measure down to the desired curtain endpoint: This may be just above the floor or lightly touching it.
- Account for rod and header style: Grommets, rings, pleats, and track systems can change how the final length sits.
If the bedroom has unusually wide windows, corner windows, or doors near the treatment area, custom planning becomes even more important. Many homeowners looking for custom blackout curtains Canada options find that professional measuring helps prevent light leaks and improves the final look.
Practical buying tips for Canadian bedrooms
In Canada, bedrooms may face very different conditions depending on season, orientation, and home type. A few practical considerations can make your selection easier:
- For bright summer mornings: Prioritize strong blackout lining, wider rod extension, and fuller panels.
- For urban homes or condos: Look for good edge coverage to reduce light from neighbouring buildings and streetlights.
- For colder climates: Energy efficient blackout curtains can be a sensible choice for added comfort near windows.
- For children’s rooms: Choose durable, easy-care fabrics with dependable room-darkening performance.
- For design-focused bedrooms: Select a face fabric that complements the room while still delivering the lining and fit needed for performance.

Should you choose ready-made or custom?
Ready-made blackout curtains can work well for standard windows when the sizing is suitable and the installation is carefully planned. However, custom blackout curtains Canada homeowners choose are often better for rooms that need a more precise fit, a more finished design, or coordination with other window treatments.
Custom options can be especially useful when:
- Windows are oversized or unusually shaped
- You want better wall-to-wall or ceiling-mounted coverage
- You are matching curtains to a specific interior style
- You need a more exact length or fullness
- You want a coordinated solution across multiple bedrooms
The right choice depends on your priorities. If your main goal is stronger darkness and a better overall fit, custom can be worth considering.
Final thoughts
