Most blackout curtains promise total darkness and deliver a dim grey room with a glowing halo around the top of the window. That gap between the label and the light is exactly why searching for the best blackout curtains for bedroom windows takes longer than it should.
We spent weeks hanging panels across bedrooms with different window sizes, rod placements and sun angles, checking what each one actually blocked rather than what the packaging claimed. What we learned is simple: fabric matters less than coverage. A mid-priced triple-weave panel hung on an outside-mount rod beats a lined designer curtain crammed inside the frame.
This guide covers 12 sets that hold up in real bedrooms, from budget unlined polyester to lined panels with a sewn-in black liner, plus one velvet option for people who want blackout performance without the clinical look. We also explain how to measure, where light leaks come from, and how to wash blackout curtains without ruining the coating.
If you want the short version, the pick at the top of our list is the one we kept reaching for. Our full method, product notes and buying guidance follow.

1. NICETOWN Black Blackout Curtains 42 x 63 inch – Best Overall
NICETOWN Black Blackout Curtains for Bedroom 42″ Wide x 63″ Long 2 Panels
Set of 2 panels
42 x 63 inch each
6 grommets per panel
Triple-weave polyester
Pros
- Blocks 85%-99% of light and UV
- Same colour on both sides so no lining shows from outside
- Soft heavy drape for the money
- Machine washable and wrinkle free
Cons
- Not a true 100% blackout so edges and grommets leak
- Needs a wider rod for full coverage
We used this set in two bedrooms, one facing a streetlight and one with direct morning sun, and it handled both better than panels costing several times more. The triple-weave polyester is thick without feeling stiff, and the colour is identical on both faces, so the window does not look like it is covered in plastic from outside.
Buyers consistently point out that these are close to blackout without reaching laboratory darkness. Over 130,000 reviews average 4.6 stars, and the recurring note is that a small amount of light edges past the grommets and the top of the panel when the sun hits directly.
The panels measure 42 by 63 inches and weigh about 2.1 pounds for the set, which is light enough for a basic tension or screw-in rod. The fabric also does temperature work: it holds warmth in winter and takes the edge off summer heat, and the dense weave softens room noise enough to improve daytime viewing.
Care is refreshingly simple. Machine wash cold, tumble dry, and the fabric comes out ready to hang without ironing, which matters more than it sounds when you are swapping panels twice a year.
Who should buy these panels
Buy them if you want the strongest general-purpose blackout curtain on this list without custom sizing. They suit standard windows, guest rooms, nurseries and any bedroom where a streetlight or early sun is the problem.
They also suit anyone who does not want to think about fabric care. A cold machine wash and a tumble dry is the whole routine.
Who should look elsewhere
Skip them if you need laboratory-grade darkness for daytime sleep or a projector. The grommet holes and side edges leak enough light to keep a screen or a light-sensitive sleeper awake.
They are also a poor match for oversized windows, since two 42-inch panels rarely span a wide opening once they are gathered.
2. NICETOWN White 100% Blackout Curtains 84 inch Long – Best Lined Blackout
NICETOWN White 100% Blackout Curtains 84 inch Long for Bedroom 2 Pieces
Set of 2 lined panels
52 x 84 inch each
Silver grommets
104 inch combined width
Pros
- Sewn-in black liner gives genuine blackout
- Two-layer build absorbs roughly twice the sound of one panel
- White face suits light bedrooms
- Tool-free silver grommet hanging
Cons
- Heavier than unlined panels so hardware must be solid
- Needs the full 104 inch width spread across the window
This is the set we recommend when the room has to go genuinely dark. Instead of a thin surface coating that can crack with washing, the blackout layer is sewn into the panel, and nearly 79,000 reviews averaging 4.8 stars reflect how rarely buyers regret that choice.
Two layers of fabric also mean noticeably better sound dampening. Reviewers who live on busy roads describe a real drop in traffic noise, and anyone with a television opposite the window will notice less screen glare during the day.
Each panel is 52 by 84 inches, so the pair covers 104 inches of rod, and the package weighs 2.25 kg. That weight is the trade-off: light-duty brackets will bow, so budget for a proper rod before the curtains go up.
Care guidance lists hand washing or dry cleaning alongside machine washing, which tells you how seriously the lining is meant to be treated. Hanging them and leaving them alone is the safest route to a long life.
Who should buy these panels
Night shift workers, migraine sufferers and anyone sleeping through daylight should look here first. The sewn-in liner is the difference between a dim room and a dark one.
They suit tall windows too, since 84-inch length reaches most standard ceilings when hung from a properly placed rod.
Who should look elsewhere
They are the wrong choice on a flimsy rod or a budget mounting bracket. The weight is real and it will show over time.
Hand wash or dry clean only is a hassle if you wash curtains often, so pick something machine washable if that is your habit.
3. LEMOMO Blackout Curtains 52 x 84 inch Set of 2 – Best Lightweight Blackout
LEMOMO Blackout Curtains 52 x 84 inches Long Black Curtains Set of 2 Panels Thermal Insulated Room Darkening Curtains for Bedroom
Set of 2 panels
52 x 84 inch each
Triple weave
8 silver grommets per panel
Pros
- Soft polyester with no chemical smell
- Thermal insulation for both seasons
- Blocks 85%-99% of light and UV
- Very light for the coverage level
Cons
- Unlined single-layer build so direct sun still glows
- White reverse looks plain from outside
We carried these up a narrow staircase and hung them in a small room without thinking about hardware, because at 1.58 kg for the pair they are the lightest full-length set we tested. Over 51,000 reviews sit at a 4.6 average, and buyers keep describing them as soft with no chemical smell straight out of the package.
Lightness is not the same as flimsy here. The triple weave still blocks 85% to 99% of light depending on colour, and the same fabric works as a thermal barrier in summer and winter. In practice that killed the afternoon heat gain in our west-facing test room.
Eight grommets per panel with a 1.6 inch inner diameter fit nearly any standard rod, and the tailored pleat falls cleanly without clips. Machine washing is allowed, which keeps upkeep simple in a household with kids.
The honest limitation is the white reverse side. With no lining, sunlight passing through the fabric shows as a pale glow from outside, and inside the room direct sun still leaves a visible shape on the panel.
Who should buy these panels
They suit anyone who needs solid dimming without heavy hardware, especially in a rental where drilling into a solid bracket is impractical.
Nurseries and kids rooms are good fits because the fabric is soft, odour free and easy to wash. If you are furnishing a whole room at once, our picks for kids bedroom sets cover the matching bedding and furniture.
Who should look elsewhere
Skip them for a home theatre or for anyone whose sleep is genuinely disrupted by daylight. This is a strong blackout curtain, not a total one.
If the window faces a bright street and you care about how the exterior looks at night, expect the pale reverse to show.
4. ChrisDowa Blackout Curtains 63 inch Long Dark Grey – Best for Small Windows
ChrisDowa Blackout Curtains for Bedroom and Living Room 63 Inches Long
Set of 2 panels
42 x 63 inch each
6 grommets per panel
Unlined polyester
Pros
- Blocks about 98% of sunlight and UV
- Thick soft fabric with no chemical smell
- Colour on both sides
- Machine washable on a gentle cycle
Cons
- Unlined so it dims rather than darkens fully
- Dark grey glows more than a true black panel
Sized for smaller openings at 42 by 63 inches, this set is a good match for the standard bedroom window that most houses actually have. Two panels at 2 pounds total are easy to put up on a basic rod, and the six silver grommets slide without snagging.
Reviewers rate it at 4.6 across more than 31,000 ratings, and the pattern of feedback is consistent: thick fabric, strong light reduction, no smell. The listed blocking figure sits around 98% for darker colours, which covers streetlights and glare very well.
Care is straightforward. Machine wash on a gentle cycle, tumble dry low and warm iron if needed. The fabric is also described as noise reducing and privacy protective, which helps in ground-floor bedrooms facing a walkway.
The colour is dark grey rather than black, and that distinction matters more than buyers expect. Lighter shades transmit more light, so this dims a room well without producing the deep darkness a night shift worker needs.
Who should buy these panels
They suit small and medium windows in nurseries, playrooms and guest bedrooms where the priority is killing streetlight without fussing with hardware.
Machine washability makes them practical for homes with children and pets.
Who should look elsewhere
They will not deliver total darkness, and the grey tone is the reason. Pick a lined panel if light sensitivity is the issue.
Tall or floor-to-ceiling windows need a longer drop, since 63 inches stops well above the floor.
5. RYB HOME Black Blackout Curtains 72 inch – Best Rod Pocket Design
RYB HOME Black Blackout Curtains for Bedroom Living Room 72 inches Long
Set of 2 panels
42 x 72 inch each
3 inch rod pocket
Plain weave polyester
Pros
- Rod pocket seals the light gap at the window top
- Black colour blocks 85%-99% of light and UV
- Triple-weave thermal barrier
- Blocks outside view with lights on inside
Cons
- Single-layer unlined fabric so it darkens rather than blackouts
- Arrives creased and needs steaming
- Rod pocket only fits rods near 3 inches
The rod pocket header is the detail that sets this set apart. Grommet curtains leave a slit of light across the top of the window where the rings sit, and a continuous fabric header closes that off, which is the first place most bedroom light leaks from.
Over 30,000 reviews average 4.6 stars. Buyers single out the sealing effect and the depth of black, and many mention that the curtains block the view from outside even with the bedroom light on, which is a genuine benefit on a ground floor.
At 42 by 72 inches the panels give a longer drop than most sets here, covering a window and still reaching the floor. The package weighs just over a kilogram, so a standard rod handles them without complaint.
There is one prep step. The panels arrive with packing creases and reviewers recommend steaming or a warm iron before hanging. Ten minutes of work, and the drape looks dramatically better afterwards.
Who should buy these panels
They suit anyone whose main complaint is a bright band of light along the top of the window. The pocket header closes it better than grommets do.
Black is the right colour to choose if light reduction matters more than a light interior.
Who should look elsewhere
Single-layer fabric means this is not a total blackout, so light-sensitive sleepers should keep looking.
You also need a rod with a diameter close to 3 inches, and you should budget time to steam out the creases.
6. PONY DANCE Black Out Curtains 72 inch – Best Satin Sheen Blackout
PONY DANCE Black Out Curtains 72 inch Long, Black, 2 Panels
Set of 2 panels
42 x 72 inch each
Rod pocket
Triple weave polyester
Pros
- Thick polyester with a subtle satin sheen
- Triple weave blocks 85%-99% of light and UV
- Colour on both sides with no lining
- Insulated for summer and winter
Cons
- Not a lined total blackout so light edges past the sides
- Rod pocket needs a rod rather than rings or hooks
This is the pick when blackout performance is the priority but a plain matte black panel looks too functional. The fabric has a faint satin sheen that catches light during the day and reads as a decorative curtain rather than a shade.
Ratings sit at 4.6 across just over 30,000 reviews, and repeat buyers describe the fabric as thick with an insulated feel and no white interior facing. The triple weave handles both heat and noise to a useful degree.
Each panel measures 42 by 72 inches with a 3 inch rod pocket and weighs 2.2 pounds. That pocket suits most standard rods, and the ripple fold pleat hangs evenly the first time.
Machine wash cold and tumble dry low, with a warm iron for wrinkles. Reviewers note a little light still edges past the sides and top, which is normal for an unlined triple weave.
Who should buy these panels
They suit west-facing bedrooms where the sun is strong but total darkness is not required. The satin finish keeps the room looking styled.
Because the colour is identical on both faces, they also work well when the window is visible from a shared hallway or courtyard.
Who should look elsewhere
Avoid them for a projector or for daytime sleeping, since an unlined panel will always let some light through.
If you prefer to hang curtains from rings or hooks, the rod pocket rules that out.
7. H.VERSAILTEX Blackout Curtains 63 inch Ivory – Best for Cream Bedrooms
H.VERSAILTEX Blackout Curtains for Bedroom Thermal Insulated Room Darkening Living Room Curtains 63 Inch Long Grommet Privacy Protection Window Curtain Panels/Drapes for Nursery,2 Panels,Ivory/Cream
Set of 2 panels
42 x 63 inch each
Lined microfiber polyester
6 grommets per panel
Pros
- Ivory colour suits light and neutral decor
- Blocks 100% of UV rays
- Thermal lined fabric holds warmth
- Soft microfiber with a clean lined reverse
Cons
- Listed blocking of 70% is lower than most rivals
- Some daylight shows at the very top in direct sun
Black is not the only colour that works, and this ivory pair is the proof. Light blocking depends on weave density and lining, not on the colour of the face fabric, so a cream curtain with a proper lining can darken a room while keeping the bedroom bright and soft during the day.
More than 23,000 reviews average 4.6 stars. Buyers report that morning sun stops waking them and the room holds warmth better in cold weather, with the soft microfiber reverse described as clean and lined rather than plastic-looking.
Each panel is 42 by 63 inches and the pair measures 84 inches wide overall, with six metal grommets per panel on a 1.6 inch inner diameter. The fabric carries Global Recycled Standard certification, which matters if you are choosing for a nursery.
Be clear-eyed about the figure though. The listing states 70% light blocking and 100% UV, which sits below the 85% to 99% claimed by most of the sets on this list. It dims effectively but it does not black out.
Who should buy these panels
They suit nurseries, guest rooms and any bedroom with a pale palette where black curtains would feel heavy. The UV filtering is a bonus for a child sleeping during the day.
A wide range of sizes and colours also makes them practical for unusual window shapes.
Who should look elsewhere
If your priority is darkness, the 70% figure will disappoint. Choose a lined panel instead.
Some buyers still see daylight at the top of the window when the sun hits directly, which is worth knowing before you buy.
8. BGment White Blackout Curtains 63 inch – Best White Panel for Total Darkness
BGment White Blackout Curtains 63 Inch Long – 2 Panels
Set of 2 panels
42 x 63 inch each
Black liner backing
6 silver grommets per panel
Pros
- Black lining backing blocks sunlight completely
- Double layer absorbs about twice the sound
- Two layers balance room temperature
- Survives a wash without ironing
Cons
- Black backing can show faintly through pale shades
- Two panels may not cover very large windows
If you want a white curtain that still produces a genuinely dark room, this is the one to buy. A sewn-in black liner sits behind the white face, so the panel looks light and airy when open while delivering true blackout when closed.
Ratings average 4.8 stars across more than 16,000 reviews, and buyers credit the liner for noticeably less daytime television glare and better sleep. The double layer also absorbs roughly twice as much sound as an ordinary single-layer curtain, which helps on a busy street.
Each panel is 42 by 63 inches with six silver grommets fitting rods under 1.6 inches. The package weighs 1.73 kg, which is heavier than unlined sets but well within what a standard bracket handles.
Care is the friendliest here: machine wash on a gentle cycle, tumble dry low, iron if needed. Reviewers highlight that the fabric comes out of the wash ready to hang with no steaming step.
Who should buy these panels
They suit anyone who wants total darkness without a black curtain. Scandinavian, coastal and pastel bedrooms all work because the face fabric stays light.
Daytime television viewers and street-facing bedrooms get a useful noise reduction bonus from the second layer.
Who should look elsewhere
Very pale shades such as baby pink can let a faint shadow of the black backing show when the window is brightly lit from behind.
Two 42-inch panels will not span a large or floor-to-ceiling window on their own.
9. MIULEE 100% Blackout Linen Curtains 52 x 84 Natural Beige – Best Linen Look
MIULEE 100% Blackout Linen Curtains for Bedroom 52×84 Inches Natural Beige
Set of 2 panels
52 x 84 inch each
Lined triple weave
8 grommets per panel
Pros
- Faux linen texture suits a bedroom or office
- Lined construction darkens the room fully
- Triple weave insulates and reduces noise
- Eight sizes available for odd windows
Cons
- Care label says do not machine wash
- Polyester creases in packaging and needs ironing
Most blackout curtains look technical. This one does not. The textured faux linen face reads as a warm neutral curtain, and the lined construction behind it delivers full blackout, which is a combination we rarely see outside custom work.
Ratings average 4.6 stars across more than 10,000 reviews, and the most common compliment is that it looks like decor rather than a light-blocking device. Triple weave handles insulation and noise at the same time.
Each panel is 52 by 84 inches with eight grommets, and the set weighs 4.1 pounds, so use a rod with solid brackets. Eight size options mean you can match an awkward window rather than settling for a standard drop.
Two cautions. The care label advises against machine washing, which is unusual for a polyester curtain and means professional cleaning or spot cleaning. The fabric also arrives creased and needs a warm iron or steam before it hangs.
Who should buy these panels
They suit bedrooms, home offices and classrooms where appearance matters as much as darkness. The beige tone works with wood, neutral and soft palettes.
If you want a linen look with real blackout, this is one of the few affordable sets that delivers both.
Who should look elsewhere
Not for you if you machine wash your curtains regularly. Follow the care label rather than the material.
Budget ten minutes for steaming after delivery, or the first impression will not be the finished look.
10. Yakamok Grey 100% Blackout Curtain Panels 84 inch – Best for Night Shift Workers
Yakamok Grey 100% Blackout Curtain Panels 84 inches, 52″ Wide, 2 Panels
Set of 2 panels
52 x 84 inch each
Sewn-in black liner
8 grommets per panel
Pros
- Two-layer build with black liner reaches 100% blackout
- Absorbs about twice the sound of a single panel
- Heavyweight panels hang straight and full
- Grey tone suits neutral bedroom decor
Cons
- Full-length lined panels are heavy for a basic rod
- Neutral grey is less dramatic than black for perceived darkness
If you sleep during the day, the sewn-in black liner is the specification that matters. Owners on night shifts describe the room going properly dark rather than grey, and the fabric weight means the panels hang straight without the rippling you get with thin curtains.
At 4.7 stars across more than 8,500 reviews, this is one of the strongest rated lined sets in the group. Reviewers also pick up on the sound dampening, which matters for light sleepers in a home near a main road.
Each panel measures 52 by 84 inches with eight silvery grommets at a 1.6 inch inner diameter. The package weighs 2.42 kg, which is among the heavier sets here, so a proper rod and brackets are not optional.
Coverage is the other half of the darkness equation. Buyers who report edge light are usually hanging the panels gathered on a rod narrower than the window, which we cover in the measuring section below.
Who should buy these panels
They suit night shift workers, light-sensitive sleepers and anyone whose street is noisy at odd hours. A grey face keeps the room from feeling severe.
Full-length lined panels also suit anyone with a tall window who wants the drop to reach the floor.
Who should look elsewhere
If your rod is a light decorative pole, this weight will pull it down. Upgrade the hardware first.
Grey will never feel as dark as black in a subjective sense even when the blocking is identical.
11. StangH Black Velvet Blackout Curtains 52 x 84 – Best Velvet Option
StangH Black Velvet Blackout Curtains Grommet Thermal, W52 x L84, 2 Panels
Set of 2 velvet panels
52 x 84 inch each
300 GSM high density
Metal grommets
Pros
- Thick 300 GSM velvet with a plush drape
- Real thermal insulation with moderate noise reduction
- OEKO-TEX Standard 100 and GRS certified
- Recycled polyester content
Cons
- Filters 65%-85% of light rather than blocking all of it
- A slight taper can appear at one corner
- Packaging creases take a day or two to hang out
Velvet is the most photogenic blackout fabric and the least literal one. This set is a filtering velvet, blocking 65% to 85% of light rather than 100%, so it turns a bright bedroom into a calm one without producing the depth of darkness a night shift worker needs.
Ratings sit at 4.8 across more than 8,200 reviews, and buyers describe it as boutique hotel luxurious. The 300 GSM weight is the highest fabric density on this list, which explains both the drape and the insulation.
Panels measure 52 by 84 inches and weigh 4.4 pounds, with metal grommets at a 1.6 inch inner diameter. OEKO-TEX Standard 100 and GRS certification make it a sensible choice for a child’s room or for anyone avoiding untreated chemicals.
One quirk to expect. Velvet can throw a faint silvery reflection when light hits it directly, and buyers who wanted total darkness note that this fabric is a filtering velvet rather than a lined blackout.
Who should buy these panels
They suit anyone who wants the look over the function. A hotel-style bedroom, a guest room and a formal living space all benefit.
Certified fabrics matter in nurseries, and the density here gives real thermal performance in both seasons.
Who should look elsewhere
Do not buy them for a projector, for migraine-triggered light sensitivity or for daytime shift work.
Velvet piles up lint and shows paw marks from cats, and the corner taper seen on some pairs will bother a perfectionist.
12. ChrisDowa 100% Blackout Curtains 63 inch Light Grey – Best for Renters
ChrisDowa 100% Blackout Curtains for Bedroom 63 Inch Long with Black Liner
Set of 2 panels
42 x 63 inch each
Double layer with black liner
6 grommets per panel
Pros
- Black liner backing blocks all sunlight and UV
- Better soundproofing than single-layer curtains
- Soft material with no chemical smell
- Machine washable on a gentle cycle
Cons
- Light grey face can show a faint shadow of the black lining
- 63 inch length does not suit tall or floor-to-ceiling windows
This lined grey set is the pick for a rental where you want real blackout without a custom order. A double layer with black liner backing blocks sunlight and UV completely, and at 42 by 63 inches the pair is short enough to hang on a tension rod inside a rented room.
Ratings average 4.7 stars across more than 4,400 reviews, with buyers reporting total light blocking, softer fabric than cheaper lined panels and a noticeable reduction in noise from outside.
Six silver grommets per panel fit rods under 1.6 inches, and the package weighs 1.67 kg, so a standard tension rod or a light bracket will hold it. Machine washable on a gentle cycle, which matters when you are not permitted to redecorate.
One caveat shows up repeatedly. On the light grey face, the black lining can cast a faint shadow when the window is lit from behind, and the 63 inch length stops short of tall or floor-to-ceiling openings.
Who should buy these panels
They suit renters, dorm rooms and short-term apartments where drilling is off the table. A tension rod plus these panels gives a genuinely dark room.
Parents of young children rate the fabric as soft and free of chemical smell, which is reassuring in a nursery.
Who should look elsewhere
Skip them for tall windows. The 63 inch drop is the single most common regret we see in reviews.
If you are very sensitive to the look of the window from inside during daylight, a black or charcoal face avoids the lining shadow.
Blackout vs Room Darkening vs Thermal: What You Actually Need
Three labels get used loosely in this category, and mixing them up is why people end up disappointed. Blackout means the fabric itself stops essentially all light, which in practice requires a sewn-in or sealed liner rather than a surface coating. Room darkening means 85% to 99% blocking, which kills a streetlight and most glare but leaves a soft glow.
Thermal refers to a different job entirely. It describes how well the fabric slows heat transfer, and it is a benefit that appears on almost every panel here through the triple-weave construction rather than a separate feature.
Choose blackout for night shift workers, migraine and light-sensitivity sufferers, nurseries and home theatres. Choose room darkening for a normal bedroom where you want less glare at night but still wake naturally at dawn.
One note on colour: dark colours block more light than light ones on the same fabric, but a light colour with a proper black liner, like the BGment white set, achieves the same result as a black unlined panel.
If you want a broader look at curtain categories, our guide to the top rated blackout curtains covers the general market. For rooms where sound matters as much as light, see our picks for soundproof curtains for gaming room windows.
How to Measure and Hang Blackout Curtains for Zero Light Leaks
Fabric performance is only half the result. The other half is coverage, and this is where most bedroom light leaks actually come from. Three rules fix the majority of problems we saw during testing.
Mount the rod outside the window frame. Installing the rod 3 to 6 inches above and wider than the frame removes the gap light travels through at the top and sides. An inside mount inside a deep recess can never achieve the same result, no matter how good the panel is.
Buy panels at least double the window width. Two panels that together equal roughly twice the window width will gather enough to overlap in the centre when closed. A window measured at 40 inches wants about 80 inches of fabric across the rod.
Choose length that breaks the light path. Hang the panels 1 to 2 inches above the floor or slightly beyond for a floor-length look. Light entering underneath a short panel is the third common leak and the easiest to fix.
For a wrap-around effect on a bay or corner window, a curved return rod pulls the panel edge toward the wall. Where a fix is not possible, magnetic strips along the side edges close most of the remaining gap.
Finally, check that your rod can carry the weight. The lined sets on this list run from 1.7 kg to 2.4 kg per pair, and repeated bowing of a cheap rod is the reason many curtains end up with a permanent light gap.
Five Common Blackout Curtain Buying Mistakes
Judging by colour instead of lining. A black panel without a liner blocks far less than a white panel with one. Check the listing for lined or black liner backing rather than colour alone.
Buying for the window, not the rod. Panel width must total twice your window width, and the header type has to match your rod. A rod pocket needs a rod close to 3 inches; grommet panels need a slim rod under 1.6 inches.
Underestimating weight. Triple weave and lined panels are heavy. Cheap brackets bend, and a bent rod creates a light gap that no fabric can fix.
Expecting a coating to last forever. Surface-coated curtains tend to crack and flake with repeated washing, which is why every lined pick here is preferred for long-term daily use.
Hanging panels that arrived creased. Several sets on this list arrive wrinkled from packaging. A warm iron or steam before hanging costs minutes and changes the finished look completely.
For exterior privacy rather than darkness, our outdoor curtains for privacy guide covers the different requirements there, while our broader outdoor curtain roundup handles patios and porches.
Frequently Asked Questions
Are blackout curtains good for bedrooms?
Yes. Blackout curtains block the light that disrupts sleep, dampen street noise, and slow heat transfer through the window. They matter most for night shift workers, light-sensitive sleepers, nurseries and home theatres, where even a dim glow can wake you.
Do blackout curtains block 100% of light?
Only if the fabric has a sewn-in or sealed liner, and only if the panels fully cover the window. Most unlined triple-weave panels block 85% to 99%. True darkness also needs an outside-mount rod and enough width to overlap in the centre.
Are room darkening or blackout curtains better?
It depends on light sensitivity rather than price. Blackout suits shift workers, nurseries, migraine sufferers and home theatres. Room darkening suits living rooms, guest rooms and anyone who wants less glare but still wants to wake with daylight.
What is the downside of blackout curtains?
The main drawbacks are a very dark room during the day, weight that needs a sturdy rod, a dark lining visible from outside on some colours, and coated fabrics that can degrade with frequent washing. A lined panel and a heavy-duty rod remove most of these problems.
Should I get room darkening or light filtering shades?
For a bedroom, curtains usually win. Light filtering shades pass roughly 50% to 70% of light, while room darkening curtains sit far higher. Outside-mount curtains also seal window edges better than inside-mount shades, which is where most bedroom light leaks originate.
Can blackout curtains reduce noise and keep heat out?
Lined double-layer panels absorb roughly twice as much sound as a single layer and cut noticeable outside noise. The same triple-weave structure slows heat transfer, which reduces summer heat gain and winter heat loss through the window.
Conclusion
The best blackout curtains for bedroom windows are not necessarily the most expensive ones, and they are almost never enough on their own. Start with coverage: a rod mounted wider and higher than the frame, panels totalling twice the window width, and a drop long enough to reach the floor.
Once the install is right, choose fabric by need. The NICETOWN black triple-weave set is our overall pick for most bedrooms, the lined white and grey sets deliver real darkness for daytime sleepers, and the ivory and linen-look panels cover the bedrooms where decoration matters more than laboratory-grade blocking.
Whichever you pick, hang them properly before you judge them. More disappointed blackout curtain buyers are dealing with a light leak from the frame than with fabric that fails to deliver.
