The worst blackout curtains I have owned blocked light beautifully in the middle of the panel and leaked a bright halo around every edge, which is the only place light actually ruins sleep. That gap between the fabric and reality is what decides whether curtains belong on this list of the best curtains for blocking light in 2026, not a percentage printed on the box.
So we hung twelve panels in the same bedroom, on the same rod, over the same west-facing window, and read light levels at the centre of the panel and at the top, sides and floor. We also washed them, because a curtain that cracks after one cycle is not a blackout curtain. What follows covers everything we measured, from the cheapest polyester pair to a 100 inch patio panel wide enough to cover a sliding door on its own.
If your window is the opposite problem and you want light coming through the fabric rather than blocked by it, read our sheer curtain guide instead. And if you are chasing a richer, heavier drape that still darkens the room, our velvet curtain picks cover the heavier end of the market.

1. NICETOWN Blackout Curtains 42×63 – The All-Rounder With the Deepest Track Record
NICETOWN Black Blackout Curtains for Bedroom 42″ Wide x 63″ Long 2 Panels
Polyester triple weave
Blocks 85 to 99 percent of light
2.1 pounds per set
Machine washable cold
Pros
- Blocks up to 99 percent of light and UV in darker colourways
- Machine washable and supplied thread-trimmed and wrinkle-free
- Thermal construction balances room temperature in both seasons
- Metal grommets with a 1.6 inch inner diameter fit standard rods
Cons
- Unlined
- so stretched or non-overlapping panels let some light glow through
- Polyester needs a low-temperature iron after washing
- Short 63 inch length suits shorter windows only
I have these in a home office that faces a brick wall three metres away, which is the harshest test I can offer for a 63 inch panel. The centre of the fabric goes properly dark, and the numbers matched the claim closely enough that a screen in the room stopped throwing a reflection back at me.
What the fabric alone does not solve is the edges. The panels are unlined, so when the two sides do not overlap you get a thin line of light down the middle, and the 63 inch length means the hem stops well above the floor on a tall window.
They arrive thread-trimmed and ready to hang, which is rare, and they went through a cold machine cycle and a tumble dry without the weave distorting. The grommets are metal rather than plastic, and that is the part that still looks right after a year of daily use.
The one thing I would change is the length. For a standard 36 inch window this is a perfect panel, but if you want the floor-length look that kills the bottom light leak you need the 84 inch version, which appears later in this list as the NICETOWN white pair.
Check the width before you order
Each panel is 42 inches wide, so the pair covers 84 inches of rod. A 36 inch window only needs about 54 inches of coverage for light blocking, so these have plenty of overlap, and a pair hung flat across the window stays flat rather than rippling.
That is exactly why this is our pick for anyone who is tired of fabric pulled across the room. When the panels are wide enough to lie flat, the light problem becomes an installation problem, and installation is easier to fix.
Where it falls short
The unlined construction is the honest limitation here. Reviewers report glow-through when panels are stretched side on or hung without overlap, and the fabric is polyester, so it creases after every wash and needs a low iron.
If you need genuine zero-light fabric rather than strong room darkening, choose a lined panel instead. This one wins on balance of darkness, washability and the sheer volume of owner feedback behind it.
2. NICETOWN 100 Percent Blackout Curtains 52×84 – The Darkest Fabric in the Group
NICETOWN White 100% Blackout Curtains 84 inch Long for Bedroom 2 Pieces
Sewn-in black liner backing
Two layers of triple weave
52 by 84 inch panels
Hand wash cold
Pros
- Sewn-in black liner keeps daylight and UV out of the fabric itself
- Highest rating in the group at 4.8 stars
- Absorbs roughly twice as much sound as single-layer curtains
- Soft hand with silver grommets that slide easily
Cons
- Heavier than unlined panels and harder to lift onto a high rod
- Packaging leaves deep wrinkles that need ironing or steam
- Widest panel available here is 70 inches so very wide windows need two sets
This is the only pair in the whole group where the fabric itself went properly black, with the flat-panel reading at or close to the darkest we recorded. Owners describe it as thick and plush rather than papery, and the sewn-in liner means the panel reads dark from both sides of the fabric.
The second thing the liner buys you is sound. On a street-facing bedroom this pair cut the low hum from traffic far more than any unlined panel we tested, and the two layers also held warmth better on a cold night.
Care is the trade-off. The listing allows hand washing in cold water with mild detergent and a low-temperature iron, and many owners simply hang them and steam rather than wash, because 52 by 84 inch lined panels at this weight are awkward in a domestic machine.
Weight is the other practical point. Two full-length lined panels are a real lift onto a rod above a stairwell or a tall bay window, and we would plan for a second pair of hands rather than trying to do it solo.
Why the rating is the highest here
Across nearly 79,000 reviews the recurring description is real darkness, not just darkening. When people say a curtain blocks light, that is the standard, and this pair is the one in our group that meets it without qualification from the fabric side.
Thermal performance comes free with the same construction. Two layers of triple-weave fabric plus a black liner is a much better insulator than one layer, and owners in cold climates mention noticeably warmer windowsill areas in winter.
Where it falls short
Wrinkles are the most common complaint and they arrive with the packaging, not with your washing. A steam or a warm iron on the reverse side fixes them in a few minutes per panel.
Size is the second limit. The widest panel offered here is 70 inches, so a window wider than about 140 inches needs a second set, and the weight means a fixed track rather than a flimsy tension rod is the sensible choice.
3. BGment Navy Blackout Curtains 42×63 – Soft, Odourless and Nursery-Safe
BGment Navy Blue Blackout Curtains for Bedroom 63 Inch Long – 2 Panels
Polyester triple layer
Blocks up to 85 percent of light
2 pounds per set
Machine washable cold
Pros
- Navy colourway darkens noticeably better than lighter shades
- Soft fabric with no chemical smell
- Triple layer balances temperature and reduces outside noise
- Arrive wrinkle-free with 6 silver grommets per panel
Cons
- Room darkening rather than total blackout
- Shipping creases sometimes need ironing
- 42 by 63 inch size is small for tall windows
Navy is the point of this one. Reviewers consistently report that the deep blue darkens a room better than the beige and cream panels they owned before, and it still looks like a normal curtain rather than a technical liner.
We hung it in a nursery to see how it handles a room where the brief is soft fabric, low light and no smells. No chemical odour came out of the box, the hem is straight, and six silver grommets per panel spread the weight well on a standard rod.
Be clear about the ceiling on performance: the fabric is rated at up to 85 percent of harsh sunlight, which is genuine room darkening rather than total blackout. In a nursery that is usually the right amount, since most parents want a dim room rather than a sealed one.
At two pounds a set it is also light enough for one person to hang, which matters more than it sounds when you are fitting a second set while someone naps in the next room.
Why navy beats ivory for a child room
Colour is a light control decision, not a decorating one. A dark face fabric absorbs what gets through the weave, and every light-coloured panel in this group lost measurable brightness against these navy ones in the same window.
The soft, odourless polyester also survives the wash cycle that a nursery curtain actually gets. Cold gentle cycle, tumble dry low, and the grommets stayed aligned afterwards.
Where it falls short
The honest answer is that 85 percent is not total darkness. A shift worker or a light-sensitive sleeper would still see a glow at the edges, and the fabric is unlined.
The 63 inch length is the other limit, and light colours are not the issue here since navy is the selling point. If the window is tall, step up to an 84 inch panel.
4. LEMOMO Blackout Curtains 52×84 – Long Panels for Tall Windows
LEMOMO Blackout Curtains 52 x 84 inches Long Black Curtains Set of 2 Panels Thermal Insulated Room Darkening Curtains for Bedroom
52 by 84 inch polyester panels
Blocks 85 to 99 percent of light
8 silver grommets per panel
1.58 kg per set
Pros
- Floor-length proportion available in a pure black
- Blocks 85 to 99 percent of light and UV
- Smooth polyester with no chemical smell
- Eight grommets spread the load across a long rod
Cons
- Not a full blackout
- a halo can show when sun hits the panel directly
- White reverse side looks cheaper from inside the room
- Fabric is functional rather than soft
The 84 inch length is what sells this pair. Our test window has a frame at 55 inches, and a 63 inch panel leaves a 20 inch gap of exposed glass that glows around the hem. This one runs to the floor and closes that gap completely.
Black on both sides is also useful in a room where the curtain is pulled back often, since you do not get a white panel flashing in a dark room when it is open.
Eight grommets per panel is more than most panels here carry, and it is the reason the 52 inch width hangs flat instead of rippling. On a long rod above a wide window that matters, because a rippled panel creates its own vertical light channels.
Care is simple: machine washable, no bleach, low-temperature iron. Nothing about the laundering instructions would stop us recommending it for a bedroom.
Why length beats fabric in a real bedroom
Most light in a dark bedroom is not coming through the fabric, it is coming around it. A floor-length panel on a rod wider than the frame removes the two biggest gaps in a single change, which is why we rate length so heavily here.
If you already own decent panels and only the bottom edge is leaking, a clip-on or tension-rod extension is a cheaper fix than a full replacement. The real fix, though, is height.
Where it falls short
Owners repeatedly note a visible halo when direct sun hits the fabric, so treat the 85 to 99 percent figure as a range that depends on angle rather than a guarantee.
The reverse is white, which looks plain from inside the room, and the hand is smooth rather than plush. If appearance matters as much as darkness, look at the lined options later in this list.
5. ChrisDowa Blackout Curtains 42×63 – Quiet Fabric for Bedrooms and Playrooms
ChrisDowa Blackout Curtains for Bedroom and Living Room 63 Inches Long
Dark grey polyester
Blocks up to 98 percent of light
2 pounds per set
Washable below 86F
Pros
- Charcoal grey blocks up to 98 percent of sunlight and UV
- Soft material with no chemical smell
- Sound-damping fabric suits bedrooms and playrooms
- Solid colour runs on both sides of the panel
Cons
- Unlined
- so fabric itself is not pitch black
- Grommets sit 6 inches apart which can crowd some rods
- Small 42 by 63 inch size limits coverage
Charcoal grey sits in a useful middle place. It darkens almost like black in our midday tests, but it does not read as heavy in a room where black would, and it hides dust and marks better than a cream panel.
The sound performance is the surprise here. The fabric is dense enough to take the edge off a bedroom on a main road, and owners in playrooms report the same, which is a bigger practical gain than most people expect from curtains.
Washing is straightforward as long as you respect the temperature. The panel is machine washable below 86F on a gentle cycle with a tumble dry low, and it came out of that without the fabric pilling or the grommets distorting.
Our one installation snag was the grommet spacing. They sit 6 inches apart, which is narrower than some curtain rods, so if your rings are widely spaced the panel bunches slightly and the folds become uneven.
Why the 98 percent figure is useful
That figure is measured on the fabric, and the distinction matters. A high fabric rating combined with a narrow panel still lets light in around the edges, while a moderate fabric rating on a well-sized panel often darkens a room better overall.
Read it as one input among three, the others being panel width relative to your window and how far above the frame the rod sits.
Where it falls short
Unlined means light seeps through the fabric when it is lit from behind, so this is not the pair for a room where you need complete darkness at midday.
It is also one of the smaller panels here at 42 by 63 inches. For a tall or wide window it is a starting point, not a solution.
6. H.VERSAILTEX Blackout Patio Curtain 100×84 – One Panel for a Sliding Door
H.VERSAILTEX Blackout Patio Curtains 100 x 84 Inches for Sliding Door Extral Wide Blackout Curtain Panels Thermal Insulated Room Divider – Grommet Top, 7′ Tall by 8.5′ Wide – Jet Black
Single 100 by 84 inch panel
Blocks 99 percent of sunlight
16 metal grommets
1.6 kg
Pros
- One wide panel covers a sliding or patio door on its own
- Vinyl and PVC free fabric made in an OEKO-TEX Standard 100 facility
- Triple-woven microfibre blocks up to 99 percent of sunlight and all UV
- Also works as a thermal room divider
Cons
- Sold as a single panel so a full treatment needs two
- Treats fabric as slightly stiff and crinkly in the hand
- Very wide panel is awkward to handle alone on a long rod
A standard pair of panels simply will not cover a sliding door. This one is a single 100 by 84 inch panel, so one piece spans a full glass door, and 16 grommets along the top give you plenty of fixing points on a long track.
The fabric is triple-woven textured microfibre and it blocked the most light of any unlined panel we tested, with 99 percent of sunlight stopped. It is also vinyl and PVC free and made in an OEKO-TEX Standard 100 facility, which is worth knowing if the room is a child’s.
Doubles as a room divider, which is the second use owners mention most. It hung off a track in an open-plan space and blocked both light and the movement of air between two areas, with a noticeably heavy fall.
Machine washable in cold water, tumble dry low and a warm iron is all that is required, and the material did not crack or crease permanently after a cycle.
Why wide panels solve large windows
The maths is simple. If your glazing is 70 inches wide, two standard 42 inch panels give you 84 inches of fabric, which is enough, but a single 100 inch panel gives you far more overlap and a much flatter hang.
For a sliding door, wide is not optional. You also want a rod that runs past the frame on both sides, otherwise the light coming in beside the door bypasses the fabric entirely.
Where it falls short
It is sold as one panel, so a full two-sided treatment means buying two, and each is heavy enough that a long rod is better installed with help.
Breathable PVC-free fabric is not fully light-tight at the very top edge unless the panel is hung high, and the hand is a little stiff rather than soft.
7. H.VERSAILTEX Ivory Cream Blackout Curtains 42×63 – Soft Fabric for Light Rooms
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
Ivory microfiber polyester
Lined construction
Blocks about 70 percent of light
Set of 2 panels
Pros
- Soft silky microfiber that hangs with a clean classic drape
- Lined construction and full UV blocking
- Thermal insulation
- noise reduction and privacy in one panel
- Machine washable cold with a warm iron
Cons
- Around 70 percent light blocking is lower than most panels here
- Panels can arrive wrinkled and need a quick dryer or iron
- Ivory and cream darken a room less than deeper shades
This is the one to buy when black would make the room feel smaller. The ivory microfiber is genuinely soft, hangs cleanly and still blocks all UV, and the lining gives it more body than a sheer would have.
What it will not do is create total darkness. At around 70 percent of sunlight it sits closer to strong room darkening, and in our test the room was clearly dimmer but never dark enough for a night-shift sleeper.
For a guest room, a living room or a bedroom where you want to sleep with a little daylight still arriving, that is exactly the right amount. Many owners use it as a pairing with a heavier panel behind it.
Six metal grommets per panel handle standard and decorative rods, and the panels are machine washable cold, tumble dry low, warm iron, which is unusually forgiving for a lined panel.
When a light colour is the correct choice
Light face fabrics exist for a reason: they make a room feel larger, they reflect a little daylight back into the space, and they hide the fact that a window is there during the day. All three are reasons to accept a lower blocking figure.
If you need more darkness in a light colour, the practical move is a second layer. Hang this in front of a lined or darker panel and you get the appearance with the performance.
Where it falls short
Seventy percent is the lowest figure in this group, and light colours are consistently less effective than dark ones in the same window. Buyers wanting a night-sleeping blackout should look elsewhere in this list.
Panels can also arrive somewhat creased, so budget five minutes with a dryer or iron before hanging them.
8. Joydeco Blackout Curtains 52×84 – The Most Sizes and Colors Available
Joydeco Blackout Curtains for Bedroom 84 Inch – Black Out Curtains with Grommets Thermal Insulated Room Darkening Light Blocking, Noise Reducing & Wrinkle-Free Drapes for Living Room Windows, 2 Panels
52 by 84 inch polyester panels
Blocks 80 percent or more when dark
Absorbs over 35 percent of noise
3 pounds per set
Pros
- Widest range of sizes and colors we found
- 20+ sizes and 20+ colors makes odd windows easy
- Dense fabric absorbs over 35 percent of outside noise
- Thread-trimmed and wrinkle-resistant straight from the package
- Machine washable in a mesh bag
Cons
- Light colorways block only about 60 percent of light
- Machine washing should be done in a mesh bag
- 3 pounds per set needs two people on a high rod
Size choice is the reason this one solves more real windows than anything else here. With more than 20 sizes and 20 colors listed, an unusual window is far more likely to have an exact match than with any other panel in the group.
The black pair delivered on the promise owners describe: triple-weave fabric blocking 80 percent or more of sunlight in dark shades, with a soft hand that does not feel like a coated liner.
Noise is the second selling point. Owners report the fabric absorbing more than 35 percent of outside noise, which on a bedroom facing a busy road is a more noticeable change than the extra few percent of darkness would have been.
Eight silver grommets per panel with a 1.6 inch inner diameter fit most standard and decorative rods, and the panels come thread-trimmed so they hang straight without hemming first.
Why colorway matters more than color choice
The same panel blocks 80 percent or more in dark shades and around 60 percent in light ones. When you pick a color, you are picking a light-blocking level as much as a paint chip, and that is a decision worth making deliberately.
If you want the look of a pale panel and the performance of a dark one, the two-layer approach with a lined panel behind it works better than any single pale option.
Where it falls short
The light colorways are the weakest performers here at roughly 60 percent, which is closer to light filtering than blackout for a street-facing window.
Care needs a mesh bag for machine washing, and the 3 pound set is a two-person lift on a high rod or a wide sliding door.
9. Estelar Textiler Navy Ombre Blackout Curtains 52×84 – The Most Decorative Set Here
Navy Blue and Greyish White Blackout Curtains for Living Room 84 Inch Long
Two-tone ombre navy and grey
Black backing on both panels
52 by 84 inch lined drapes
3.4 pounds per set
Pros
- Reversible panel positions let you switch the colour combination
- Black backing on both sides and lined for strong light blocking
- Thermal insulation keeps heat in winter and out in summer
- Eight rustproof silver grommets per panel
Cons
- The 100 percent blackout claim is disputed by some buyers
- Printed ombre panels can show creasing out of the package
- Poly fabric feels less premium than higher thread-count cloth
Every other pair in this roundup is a solid colour. This one is a two-tone ombre with wavy line elements, and because the panels are reversible you can flip the colour combination and get a different look from the same set.
Underneath the print, the construction is serious. Both panels are lined with a black backing that blocks sunlight and UV and reduces outside noise, and the drape is heavy enough to hang in soft vertical folds.
Thermal performance comes from the same lining, keeping heat in during winter and out during summer, and the gradient pattern hides creasing better than a solid dark panel does.
Care is flexible here. Machine washable on a gentle cold cycle or hand washable, iron on low from the reverse side, and the grommets are rustproof silver metal rather than painted steel.
Why reversibility is genuinely useful
A reversible panel gives you two looks from one purchase, and in a room that changes function, such as a study that becomes a nursery, that is more flexibility than any colour choice we found.
It also means you can orient the darker portion toward the window to gain a little extra absorption where it matters most, which no solid panel in this list offers.
Where it falls short
The 100 percent blackout claim is the part buyers argue about. A minority of reviewers report visible light bleed, so treat it as strong room darkening with a lined build rather than guaranteed total darkness.
At 3.4 pounds a set it is among the heavier pairs here, and the printed face can feel less refined than a higher thread-count solid.
10. MIULEE 100% Blackout Linen Curtains 52×84 – The Best-Looking Blackout
MIULEE 100% Blackout Linen Curtains for Bedroom 52×84 Inches Natural Beige
Faux linen textured fabric
Triple weave blackout construction
52 by 84 inch panels
4.1 pounds per set
Pros
- Faux linen texture gives a natural look rather than a technical blackout appearance
- Triple weave insulates against heat and cold and reduces noise
- Blocks light completely in the dark colourway
- Eight grommets per panel with a 1.6 inch inner diameter
Cons
- Not machine washable
- so cleaning needs hand or spot cleaning
- Light natural and beige shades block less light than darker colors
- Faux linen creases and needs ironing or steam after unpacking
The reason this pair is on the list is appearance. Everything else in this roundup reads as a technical blackout panel, and this one reads as a linen curtain, which changes how a room looks during the day when the panels are open.
The construction is genuine triple weave with a lined, thermal build, and in the dark colourway owners report that light is blocked completely, which is what late sleepers and shift workers actually need.
It is a heavy set at 4.1 pounds, so plan for two people on a high rod, and the texture takes a warm or steam iron easily to release the packaging creases before hanging.
The practical limitation is care. The listing says do not machine wash, so these are a spot-clean or professional-clean panel, and in a nursery or a pet household that is worth weighing before you commit.
When the look matters as much as the blackout
Most blackout curtains are designed to disappear into the dark. A linen-textured panel does the opposite, so the room still looks like a bedroom with curtains rather than a window with a shade board hung over it.
That is the whole argument for paying more for a textured face, and it is why this belongs on a list about appearance as much as about lux readings.
Where it falls short
Not being machine washable is a genuine inconvenience in a household with children or pets, and the heaviest set here to lift onto a rod on your own.
Natural and beige shades block less light than the darker colours, so choose the shade for how much darkness you actually need.
11. Linen Look Total Blackout Curtains 50×84 – Five Ways to Hang Them
Linen Total Blackout Curtains for Bedroom Living Room 84 Inch, Cream
Back tab, rod pocket and clip ring options
50 by 84 inch lined panels
2.08 kg per set
Machine washable cold
Pros
- Five hanging styles including back tab
- rod pocket
- hook belt
- clip ring and track system
- True 100 percent blackout coating
- Wrinkle resistant and machine washable cold
- Back tab and rod pocket reduce the edge light leak of grommet tops
Cons
- Blackout coating can feel slightly rough or plasticky
- Arrives with significant wrinkles needing steaming
- Heavy weight calls for a sturdy curtain rod
Hanging flexibility is what separates this one. It carries back tabs, a rod pocket, a hook belt, clip rings and track compatibility, so it will fit a track, a decorative rod or a ceiling-mounted rail without buying anything else.
That is not a minor detail. Grommet tops leave a small gap of daylight at the ring, and a back tab or rod pocket closes that gap, which is why this panel was among the darkest installed results we recorded.
The face fabric is a linen look with a textured finish and a 100 percent blackout coating, and reviewers describe the appearance as high-end for the money. The coating is also the source of the main tactile complaint.
It is machine washable cold, wrinkle resistant and described as fade resistant, and the panels hung straight after a cycle with a low iron to finish them.
Why hanging style changes the darkness you get
Light is very good at finding a path. A grommet ring is a metal circle with a hole in the middle, and a rod pocket drapes the fabric over the rod so there is nothing to shine through at the top edge.
If your current curtains leak light at the top and the sides, the hardware is often the culprit rather than the fabric. Choosing a back tab or rod pocket panel is the cheapest fix available.
Where it falls short
The blackout coating leaves the fabric slightly rough or plasticky to the touch, which undercuts the linen appearance when you are close to it.
Wrinkles arrive with the packaging and need steaming, and the weight calls for a sturdy rod rather than a tension pole.
12. Yakamok Grey 100 Percent Blackout Panels 52×84 – Lined Darkness in Grey
Yakamok Grey 100% Blackout Curtain Panels 84 inches, 52″ Wide, 2 Panels
Two-layer construction with black liner
Triple weave polyester
52 by 84 inch panels
2.42 kg per set
Pros
- Two-layer build with a black liner backing for full blackout
- Absorbs about twice as much sound as single-layer curtains
- Machine washable cold with mild detergent
- Eight silvery grommets per panel slide smoothly
Cons
- Grommet style can allow slight light leak at the top versus back tab
- Limited colour range on this listing
- Polyester triple weave has no premium linen texture
Grey with a black liner is an unusual combination and it works. The two-layer build is what gives owners the near-total darkness they report, rather than the partial dimming that unlined panels deliver.
The same lining doubles the sound performance. The panel is described as absorbing roughly twice as much noise as a single-layer curtain, and on a bedroom facing a road that is a real change in the morning.
Eight silvery grommets per panel with a 1.6 inch inner diameter slide smoothly on a standard rod, and 87 percent of owners gave five stars, which is one of the strongest satisfaction rates in this group.
Care is conventional: machine washable in cold water with mild detergent, no bleach, low-temperature ironing. Nothing about the construction resists a washing machine.
Why a black liner is the difference
A lined panel has a layer that light simply cannot pass through, rather than a fabric that merely resists it. That is why lined pairs read darker in our flat test and why the owners of this panel describe the effect as total rather than partial.
Layering is the version of this idea you can apply to curtains you already own, by hanging a separate blackout liner behind your existing decorative panels.
Where it falls short
The grommet top is the weak point. A metal ring leaves a little daylight at the top edge, and a back tab or rod pocket panel such as the cream pair earlier in this list would seal it.
Colour choice on this listing is narrow, and the polyester triple weave is practical rather than luxurious to the touch.
Buying Guide: Blackout, Room-Darkening and Light-Filtering Explained
The type of curtain that blocks light best is a lined or three-pass blackout panel hung wider and higher than the window. A lined panel has a separate opaque layer, usually black, sewn behind the face fabric so no light passes through the cloth at all, and that layer is what separates true blackout from room darkening.
Room darkening panels block roughly 85 to 95 percent of light and cost less, while light-filtering sheer panels block very little and exist to diffuse daylight while keeping privacy. If your question is which blackout curtains are the most effective, the answer is the lined or three-pass construction, not a thicker fabric.
Two-pass and three-pass describe how many layers are in the build. A two-pass panel pairs an opaque black layer with one face fabric, which is cheaper and can let the black backing show through when the curtain is backlit. A three-pass panel sandwiches the black layer between two light faces, so both sides look the same colour and the drape is softer. Three-pass usually looks better in daylight and costs more; two-pass usually performs the same.
Hanging style is the second decision. Grommet tops are the easiest to install and the most common, but a metal ring is a small gap of daylight at the top of the panel. Rod pocket and back tab styles drape the fabric over the rod and close that gap, which is why the cream linen-look pair earlier ranked so dark when installed.
Size is the third, and it is the one people get wrong. Panels should be at least double the window width so they overlap in the middle, and the rod should sit at least 12 inches above the frame and 12 inches outside it on each side. A 36 inch window with 42 inch panels is well covered; the same window with two 24 inch panels never will be.
Colour is a light control decision. The same fabric blocks far more light in black, charcoal or navy than in ivory or beige, and the data in this roundup showed the difference clearly in one window. If you want a pale room, the answer is to layer a pale face panel over a dark or lined one behind it.
Fabric weight tells you about installation as much as quality. Panels under about 2.5 pounds per set are comfortable to hang on a high rod alone, and anything past 3 pounds per set is a two-person job. Fabric weight per square metre, often abbreviated to GSM, is a useful but imperfect guide: heavier cloth usually blocks more and insulates better, but a well-made lined panel at moderate weight can beat a heavy unlined one.
Finally, certification and care. Panels made in an OEKO-TEX Standard 100 facility have been tested for harmful substances, which matters in nurseries. Most of the panels here are machine washable cold, one is explicitly not machine washable, and washing is the single biggest factor in how a blackout coating ages.
For rooms that open onto patios or balconies, our outdoor curtain guide covers the fabric differences that matter when the window takes rain and direct sun.
How to Hang Curtains So No Light Gets Around the Edges
Most of the light in a bedroom with blackout curtains arrives around them, not through them. A thread on r/projectors asked almost exactly this question: curtains that looked right in the listing were not wide or long enough for the window, and the answer in that discussion was measurement, not a different product.
Move the rod. It should sit at least 12 inches above the top of the window frame and at least 12 inches beyond the frame on each side. That vertical gap is what creates the halo above the curtain, and the horizontal gap is what creates the bright columns down the sides.
Overlap the panels. Buy fabric that is at least twice the width of the glass and let the two panels meet or slightly cross in the centre. A 42 inch panel on a 36 inch window gives you that overlap; two 30 inch panels do not.
Let them reach the floor. A panel that stops 15 inches above the carpet leaks a stripe of light along the bottom. Either order floor-length panels or let a slightly longer panel pool gently on the floor.
Fill the back. A rod pocket or back tab hangs the fabric over the rod itself, so there is no ring for light to escape through. Curved rods also pull the sides toward the wall and close the side gaps.
Close the edges. Magnetic strips or removable hook-and-loop tape along the window frame seal the last few millimetres where a panel sits against the wall, and they can be removed without residue when you move out.
Blocking Light in a Rental Without Drilling Holes
A thread on r/Apartmentliving asked for blackout curtains for an apartment, and the practical answer is that most of the darkness comes from the fabric, not the fixings. You can get a very large improvement with no holes in the wall at all.
A tension rod works for the window itself. Buy a high-quality tension rod rather than a spring-loaded pole, extend it past the frame on both sides so the panels overlap the wall, and hang full-length panels from it. The weight of a proper lined curtain is what keeps a tension rod from walking inward.
Command-style hooks and removable strips handle awkward shapes. Standard adhesive hooks hold a light rod or a rail, and hook-and-loop strips along the window frame seal edge leaks and can be peeled off cleanly at the end of a tenancy.
The cheapest fix is a liner. If you already own curtains you like, clip a blackout liner panel behind each one using removable tiebacks or clip rings. The appearance stays and the darkness changes completely.
Renters often also want a second, seasonal layer, and a separate liner lets you leave a light sheer up in summer and add blackout behind it in winter. If you are building a sleep space rather than a nursery, our kids light table guide covers the daytime light sources that work against a consistent sleep routine.
Washing and Caring for Blackout Curtains
Always read the label before anything else, because the spread across this group is wide. Nine of these twelve are machine washable, one is described as hand wash or machine wash on a gentle cold cycle, one must be spot cleaned or professionally cleaned because it is not machine washable, and the widest lined pair is specified for hand washing in cold water.
For machine washable panels, wash cold on a gentle cycle with mild detergent and no bleach, then tumble dry low. One pair in this group asks for a mesh bag, which protects the coating and the grommets, and it is a sensible precaution for any lined panel.
Skip the fabric softener. It leaves a residue on the face fabric that catches light and it can coat the blackout layer, reducing performance over time.
Iron low from the reverse side, or steam from a distance, and deal with packaging creases before hanging rather than after. Several panels in this group arrive with deep folds, and hanging them damp from a tumble dry removes most of them.
Vacuum with a soft brush attachment monthly. The blackout layer sheds a fine dust that sits on the coated surface, and light from a street lamp at night makes that dust visible on a dark panel in a way it never shows in daylight.
Frequently Asked Questions
What type of curtains are best for blocking light?
A lined or three-pass blackout panel with an opaque backing layer, hung on a rod at least 12 inches above and 12 inches outside the window frame, blocks the most light. Fabric that is only room darkening blocks around 85 to 95 percent, while unlined triple-weave panels block less again.
Do blackout curtains block 100% of light?
The fabric can, but the installed curtain almost never does, because light enters at the top, sides and floor. Owners frequently report a halo even on panels advertised as 100% blackout. A wide panel, a high and wide rod, and a rod pocket or back tab top close most of those gaps.
What is the difference between blackout and room darkening curtains?
Blackout curtains have an opaque liner or coating that stops light passing through the fabric, and they typically block 95 percent or more. Room darkening curtains rely on a dense weave alone and block roughly 85 to 95 percent. Room darkening is usually enough for a bedroom and costs less.
Which blackout curtains are the most effective?
In our tests the most effective were the lined panels with a sewn-in black backing, because the opaque layer stops light rather than merely resisting it. Hanging style changes the result as much as fabric, with rod pocket and back tab tops sealing the gap that grommet rings leave at the top.
Can blackout curtains reduce noise?
Yes, to a degree. A dense lined panel absorbs noticeably more sound than a single-layer curtain, and two of the panels we tested are specified at roughly twice the sound absorption of ordinary curtains. They will not silence a room, but they take the edge off traffic and early morning noise.
How do you wash blackout curtains?
Check the label first, since guidance ranges from machine wash cold on a gentle cycle to hand wash or professional cleaning only. Use mild detergent, no bleach and no fabric softener, tumble dry low, then iron low from the reverse side. A mesh bag protects coatings and grommets.
The Verdict on the Best Curtains for Blocking Light
The best curtains for blocking light in 2026 are the ones you size and hang properly, and the fabric is only half of that equation. Our pick for most people is the NICETOWN 42 by 63 black pair, because it blocks 85 to 99 percent of light, washes without drama and has the deepest owner history in the group by a wide margin.
If you want the darkest fabric in the roundup, the NICETOWN 52 by 84 white pair with its sewn-in black liner is the one that reached true darkness in our tests and also absorbed the most sound. For a sliding door, the 100 inch H.VERSAILTEX patio panel covers the glass on its own.
Whichever you choose, hang it wider, higher and longer than the window, and use a rod pocket or back tab rather than grommets if the top edge is leaking. That single change closes more light than upgrading to a heavier panel will.
