Navy blue blackout curtains can make a bedroom darker, add privacy, and help soften the room’s look. The right pair depends on more than color: panel size, hanging style, fabric construction, and the amount of light the curtains are designed to block all affect how well they fit your window and routine. These five options include full-length and shorter panels, grommet and tab-style headers, and different levels of stated light blocking.

Our Picks: Best Navy Blue Blackout Curtains For Bedroom reviews
RYB HOME: Full-Length Grommet Curtains for a Darker Room
RYB HOME’s pair includes two 52-inch-wide by 84-inch-long panels. The product description says the densely woven fabric provides a 100% blackout effect and adds thermal insulation. That combination makes this a strong option to consider if you want long curtains for a bedroom where bright outdoor light is a concern.
Metal grommets make the panels straightforward to hang on a compatible curtain rod and easy to slide open or closed. The trade-off is that this top style may leave small gaps around the rod or along the sides of a window. As with any curtains, the result depends on the rod placement, window coverage, and fit—not only the fabric’s stated blackout level.
The panels are machine washable, with care instructions calling for non-chlorine bleach only, warm ironing when needed, and low-temperature tumble drying. Compared with the shorter options here, the 84-inch length may suit taller windows or a longer drop from the rod, but it may be too long for some rooms.
Pros:
- Two wide, full-length panels
- Described as 100% blackout
- Thermal-insulated fabric
- Grommet top for simple hanging and movement
Cons:
- Grommets may allow some light near the top of the window
- The 84-inch length may not suit shorter windows
Verdict: Choose RYB HOME if you want wide, full-length navy panels with a grommet top and a stated 100% blackout effect.
Diraysid: Wide, Triple-Weave Panels for Bedrooms and Living Rooms
Diraysid’s set has two polyester panels, each measuring 52 inches wide by 84 inches long. Its triple-weave fabric is described as blocking 85% to 99% of light, so it is intended to darken a room rather than guarantee complete darkness. The range may appeal if you want substantial light reduction but do not need the strongest stated blackout level in this group.
The thermal-insulated construction is designed to help balance room temperature, and the simple panel design can work in either a bedroom or living room. The product information does not specify a hanging style, so check the listing details and images to confirm that the header will work with your rod before ordering.
At 52 inches wide per panel, the pair offers more total fabric width than the MIULEE or BGment sets. That can help with coverage, though you should still measure your window and account for the fullness you want when the curtains are closed.
Pros:
- Two wide panels measuring 52 x 84 inches each
- Triple-weave fabric with stated 85%–99% light blocking
- Thermal-insulated construction
- Machine washable
Cons:
- Light blocking is not described as 100%
- The hanging style is not specified in the supplied product details
Verdict: Consider Diraysid if you want wide, full-length panels and strong room darkening without relying on a stated 100% blackout claim.
MIULEE: A Shorter Pair for Compact Windows
MIULEE’s pair is designed for windows that need a shorter drop: each panel measures 40 inches wide by 63 inches long, for 80 inches of combined width. The fabric is 225 GSM polyester with a triple-layer weave and a black yarn layer in the middle. Six anti-rust silver grommets on each panel fit rods with an inner diameter of up to 1.6 inches.
The product description gives a light-blocking range of 60% to 95%, with darker colors blocking more light than lighter shades. Since this is the navy option, it may provide more light reduction than a lighter color in the same range, but the description does not promise complete darkness. Its shorter length can work for lower windows, while it may not provide the floor-length look or coverage some bedrooms need.
The curtains are machine washable in cold water on a gentle cycle and can be tumble dried. The product also describes the fabric as thermal insulating. Compared with the wider 52-inch panels in this list, MIULEE offers less total width, so measure carefully if you want the curtains to overlap the window generously.
Pros:
- 63-inch length for shorter windows
- Triple-layer polyester construction
- Six grommets per panel for compatible rods
- Machine-washable care instructions
Cons:
- Less total panel width than the wider options
- Stated light blocking varies by color and does not promise complete blackout
Verdict: MIULEE is a practical choice if your window needs 63-inch curtains and you prefer a grommet header, but it is less suitable for wide or tall windows.
BGment: Flexible Hanging Options in a 63-Inch Length
BGment’s set includes two panels measuring 42 inches wide by 63 inches long. Its main distinction is the dual-header design: you can hang the curtains from back tabs, use the 3-inch rod pocket, or attach clip rings. Clip rings are not included, so you would need to supply those separately if you choose that setup.
The product describes the curtains as blocking 80% to 90% of sunlight, with darker colors working better. They are also designed to help insulate against summer heat and winter chill and to reduce outside noise. Treat those as intended benefits rather than a guarantee of a particular room temperature or noise level.
The shorter length and flexible hanging methods can make this pair easier to match with a range of bedroom styles. However, the total width is less than the 52-inch-wide panels from RYB HOME and Diraysid, so the pair may offer less coverage on a broad window.
Pros:
- Three hanging options: back tabs, rod pocket, or clip rings
- Two panels sized for shorter windows
- Thermal-insulated design
- Machine washable on a gentle, cold-water cycle
Cons:
- Clip rings are not included
- Stated light blocking is below a full blackout claim
Verdict: Pick BGment if you want a shorter curtain with more flexibility in how it hangs, and you are comfortable with room-darkening rather than complete blackout.
INOVADAY: Linen-Look Panels with Three Hanging Styles
INOVADAY’s two panels measure 50 inches wide by 84 inches long. They pair a linen-look outer fabric with blackout lining, creating a more textured appearance than a plain, smooth curtain. The product describes the lined panels as providing a 100% blackout effect, making them a contender for bedrooms where daytime sleep or reduced sunlight is a priority.
The three hanging choices are back tabs, a 3-inch rod pocket, and clip rings, which are not included. Back tabs or the rod pocket may help cover more of the top of the window than a grommet header, while clip rings can make opening and closing easier. The product also describes a grey liner backing intended to block heat and cool air and dampen outside noise.
Compared with RYB HOME, INOVADAY offers a linen texture and more ways to hang the panels, but its panels are slightly narrower. The curtains are machine washable; the care instructions say not to bleach and allow low-temperature tumble drying when needed. For the darkest result, plan to cover the window edges as well as the glass, since light can still enter around a curtain.
Pros:
- Two full-length panels with blackout lining
- Linen-look texture for a less plain appearance
- Back-tab, rod-pocket, and clip-ring hanging options
- Thermal lining and machine-washable care instructions
Cons:
- Clip rings are not included
- Panels are slightly narrower than the 52-inch-wide options
Verdict: Choose INOVADAY if you want full-length, linen-textured curtains with a blackout lining and multiple ways to hang them.
How to Choose Navy Blue Blackout Curtains for Your Bedroom
Measure the window and the curtain drop
Measure the width of the window and the space you want the curtains to cover, then check each panel’s width and length. Remember that the listed width is for one panel, not necessarily the pair. A wider set can provide more coverage and fullness when closed. For length, measure from the curtain rod to your preferred stopping point, such as the sill, below the window, or near the floor.
Decide how dark you need the room
Product descriptions use different light-blocking claims: some say 100% blackout, while others give a range such as 80% to 90%. These figures describe the curtain fabric, not necessarily the darkness of the whole room. Light can still come through gaps at the sides, top, or bottom. If you need a very dark bedroom, consider how the curtains will cover the full window area and whether the header style leaves space around the rod.
Match the header to your curtain rod and routine
Grommets slide onto a compatible rod and make it easy to move panels. Back tabs and rod pockets create a different look and may cover more of the top edge, while clip rings allow another hanging option but may need to be purchased separately. Check the product details for rod compatibility and included hardware before ordering.
Choose a fabric look that works with your room
Navy blue can coordinate with many bedroom colors, but the finish and texture affect the overall style. A linen-look panel such as INOVADAY’s has a more textured appearance, while other options emphasize woven or triple-weave construction. If the curtains will be a strong color feature, consider how their shade and texture will look alongside your bedding, walls, and existing window treatments.
Consider insulation and care instructions
Several of these curtains are described as thermal insulated, which may help moderate heat transfer through a window. Results will depend on the window and how completely the curtains cover it. Check the washing instructions too: the options here call for machine washing, but recommended water temperature, cycle, drying method, and ironing instructions vary by product.
Set realistic expectations for noise and light gaps
Some product descriptions mention reducing outside noise, but curtains should not be treated as soundproofing. Likewise, even heavy blackout fabric cannot block light that travels around an uncovered window edge. Choose a panel width and hanging style that suit your window, and consider the rod placement if limiting light gaps is important to you.
Frequently Asked Questions
Do blackout curtains make a bedroom completely dark?
Not always. The fabric may be designed to block most or all light, but light can still enter around the sides, top, or bottom of the panels. Window coverage and the curtain’s hanging style both matter.
Which curtains in this list are described as 100% blackout?
RYB HOME and INOVADAY describe their curtains as providing a 100% blackout effect. That claim refers to the product description; it does not guarantee that no light will enter around the edges of your window.
Are all five options sold as a pair?
Yes. Each product description specifies a package of two panels. Check the listed dimensions carefully because the measurements are given per panel, and the widths differ between products.
What curtain length should I choose for a bedroom?
Choose based on the distance from your rod to the point where you want the curtains to end. The options here include 63-inch and 84-inch lengths. Measure before ordering so you do not end up with panels that are too short or too long for your window.
Which option has the most flexible hanging style?
BGment and INOVADAY offer back-tab, rod-pocket, and clip-ring hanging options. Clip rings are not included with these products, so you may need to buy them separately. RYB HOME and MIULEE use grommets.
Can thermal blackout curtains lower energy costs?
The products are described as thermal insulated and designed to help balance room temperature. They may help limit heat transfer through a covered window, but the actual effect depends on your window, curtain coverage, and room conditions. The product information does not establish a specific savings amount for your home.
Final Recommendation
For a wide, full-length pair with a stated 100% blackout effect and a simple grommet header, RYB HOME is the most straightforward pick. Choose INOVADAY if you prefer linen-look fabric and multiple hanging options, or Diraysid if its wide panels and stated room-darkening range better match your needs. For shorter windows, compare the 63-inch MIULEE and BGment options, paying close attention to their different widths and light-blocking claims.
