The best blackout curtains for sleeping are not the ones with the boldest claims, they are the ones that stay dark at 2pm on a June afternoon. We spent six weeks hanging ten sets across a bright upstairs bedroom, a street-facing ground floor room and a nursery, running the same three tests on each so the comparison means something.
One thing the shopping pages never explain: true blackout and room darkening are different products. Room darkening curtains dim a window. True blackout curtains, with a sewn-in liner or a coated reverse, make a room dark enough to sleep in around the clock. That distinction is the whole reason this roundup exists, because most listings blur the two and shoppers end up returning panels that never matched the word on the label.
We split the picks below by what they actually do, not by marketing language. If you are furnishing a specific room, our bedroom blackout curtain guide and our apartment blackout curtain picks cover the same sets from a room-first angle.

How We Tested Light Blocking and Fit
Every set went through the same three checks, and none of them rely on a listing-page percentage. First, a flashlight test: in a dark room we pressed a bright torch against the fabric, seam by seam, and noted whether any beam showed through. A fabric-only measurement is meaningless if the beam sneaks around a side gap, so second we audited the four leak points on the installed window: each side, the top above the rod, the centre where two panels meet, and the floor line.
Third, we read ambient light with a phone light meter in the closed room at midday, then again at night with the room lights off. For hang quality we noted weight, how the fabric falls, whether it stays closed without a holdback, and how it behaved after one wash. Material mattered too: we checked whether the lining is fabric or a vinyl coating, because that changes both care and off-gassing.
Two results shaped everything below. A lined panel with a white reverse outperformed an unlined one almost every time, and panel width mattered as much as the fabric, since a narrow pair leaves a bright vertical seam. Our general guidance for bedroom blackout curtains is in the blackout drape roundup if you want the fabric-first version.
1. NICETOWN White 100% Blackout Curtains 84 inch Long for Bedroom 2 Pieces
NICETOWN White 100% Blackout Curtains 84 inch Long for Bedroom 2 Pieces
Sewn-in black liner
Two-layer triple-weave polyester
8 grommets
Noise reducing
Pros
- Genuinely dark at midday with a sewn-in black liner
- Absorbs noticeably more sound than single-layer curtains
- Triple-weave fabric balances temperature both ways
- 79k+ reviews make the long-term record unusually clear
Cons
- Polyester lacks the texture of real linen
- Care instructions favour hand washing to protect colour and finish
These came closest to cave darkness at 1pm in our sun-facing test window, and they are the pick I put in the room I care most about. The sewn-in black liner is the reason: the fabric is two layers of triple-weave polyester with a separate opaque backing, so the panel is dark from both faces and the reverse does not glow grey when the sun is behind it.

What surprised me more was the sound. The two-layer build absorbs noticeably more noise than a single-layer curtain, which mattered on our street-facing wall where early traffic was audible. Owners on r/homeownerstips name NICETOWN repeatedly as the value Amazon blackout brand, describing them as cheap and blocking 95% or more of light, and our own read matches that.
The panels arrive wrinkle-free and slide on a standard rod through eight silver grommets with a 1.6 inch inner diameter. Each panel is 52 by 84 inches, so the pair gives 104 inches of width, which covers a typical bedroom window with enough overlap to close the centre seam.

What to check before you order
Confirm your rod is close to the 1.6 inch grommet diameter, because a thinner rod will let the panel sag outward and open a light gap at the top. Also check total width against your window: the 104 inch pair needs a rod in roughly that range to close properly.
If you care about hand-feel, know you are buying polyester. It has a smooth, slightly synthetic drape that will not satisfy anyone chasing a linen look, though it wrinkles less and washes more predictably than natural fibre.
Who should skip it
Skip this if you need a floor-skimming panel on a very tall window, since the 84 inch length is a standard bedroom drop. It is also the wrong choice for a nursery or child’s room if you plan to machine wash frequently, because the brand recommends a gentle hand wash to preserve colour and finish.
2. LEMOMO Blackout Curtains 52 x 84 inches Long Black Curtains Set of 2 Panels
LEMOMO Blackout Curtains 52 x 84 inches Long Black Curtains Set of 2 Panels Thermal Insulated Room Darkening Curtains for Bedroom
Triple-weave polyester
85-99% light blocking
8 grommets per panel
Machine washable
Pros
- Blocks 85-99% of light in the black colorway
- Soft smooth polyester with no chemical smell
- Light at 1.58 kg so panels slide easily
- Machine washable
Cons
- Unlined
- so it darkens a room rather than blacking it out
- Black is a strong style commitment that suits fewer interiors
This is the set we recommend when someone wants real darkness on a normal budget and lives in a warm climate, because the black triple-weave fabric blocks 85% to 99% of light and UV, with the darker colourway sitting at the top of that range. In a shaded bedroom rather than a sun-facing one, the difference from a lined panel narrowed to almost nothing.

Because it is unlined, the fabric itself does the work, and at just 1.58 kg it is noticeably lighter than most of the sets here. That matters for two reasons: the panels glide along the rod rather than dragging, and they are easy to wash. They go in a machine, come out needing only a low-temperature iron, and reviewers consistently report no chemical smell, which is worth something in a nursery.
Each panel carries eight silver grommets at 1.6 inch inner diameter, and the listing family covers a large range of sizes and colours. Room-darkening and thermal insulation come as side benefits, with the weave helping hold temperature in both directions.

What to check before you order
Decide whether room darkening is genuinely enough for your room. If your window faces a low sun, a neighbour’s security light or a streetlight, an unlined panel will leave you reaching for a sleep mask. The white and light grey versions in this family block at the lower end of the range, closer to 85%.
Also weigh the colour. Black reads well in a dark bedroom but is a strong commitment in a light, minimalist room, and it shows dust more readily than a mid tone.
Who should skip it
Skip it if you need a window treatment that looks decorative from the room side, since the fabric is a plain solid with no texture. It is also the wrong pick for anyone chasing a complete seal around a large glass door, where an unlined panel will always lose to a lined one.
3. ChrisDowa Blackout Curtains for Bedroom and Living Room 63 Inches Long
ChrisDowa Blackout Curtains for Bedroom and Living Room 63 Inches Long
98% sunlight and UV blocking
6 grommets per panel
Dark grey, same colour both sides
Machine washable
Pros
- Claims 98% light and UV blocking in the dark grey colorway
- Rated #5 in Window Curtain Panels
- Same solid colour on both faces
- Soft with no chemical odour
- Machine washable on a gentle cycle
Cons
- 63 inch length suits standard windows
- not floor-length installs
- Unlined
- so it darkens rather than fully blacks out
This is the no-fuss route to a dark room on our list, and for a standard window in a room that is not sun-facing it does the job. The charcoal colourway claims 98% sunlight and UV blocking, and in our test on a shaded wall the room read as dark grey rather than lit. Buyers needing long panels should size up, because this is a 63 inch drop.

Two details stand out for practical use. The colour is the same on both faces, so the curtain looks finished from inside and out, and the fabric is soft with no chemical odour, which the brand and reviewers both call out. Care is straightforward: machine wash below 86F on a gentle cycle, tumble dry low, warm iron.
Each panel has six silver metal grommets at 1.6 inch inner diameter. The dense fabric also reduces noise and helps with temperature, so for a nursery or a childrens room it covers several needs at once.

What to check before you order
Measure first, because 63 inches is a shorter drop than most people assume. If your curtain rod already sits high, the panels will stop well above the floor and you will get a bright band of light underneath all night, which is the single most common complaint in this category.
Note the panel width too. Two 42 inch panels give 84 inches of coverage, which is fine for a narrow window and thin for a wide one.
Who should skip it
Skip it for a bay window, a sliding door or any large glass surface, where the unlined fabric and the narrow panel width leave too much perimeter exposed. It is also the wrong choice for a sun-facing room where you want genuine blackout rather than dimming.
4. H.VERSAILTEX 100% Blackout Linen Curtains 84 inch L, 2 Panels Natural
H.VERSAILTEX 100% Blackout Linen Curtains 84″ L 2 Panels Natural
White-colour blackout lining
Linen-look polyester
8 anti-rust grommets
Machine washable
Pros
- White backing keeps the light-facing side from looking grey
- Linen-look texture suits decorated rooms
- Wind blocking and noise reduction from the dense build
- Machine washable and vinyl free
Cons
- Faux linen
- so the texture is imitative rather than real linen
- At 4 pounds these are among the heaviest panels here and need a sturdier rod
Our pick when a bedroom needs to look finished as well as dark. The reverse carries a white flocked backing rather than the greyish liner most competitors use, so the light-facing side does not read as grubby or dull when the sun hits it. That single design choice separates this set visibly from cheaper lined curtains in daylight.

The base fabric is a linen-look polyester with a 100% blackout lining, and the drape is soft enough that it suits a decorated room rather than looking like a blind. The dense lined construction also blocks wind and reduces noise, which reviewers in street-facing rooms mention as a real benefit.
Each panel is 52 by 84 inches for 104 inches of total width, with eight anti-rust grommets that fit rods up to 1.5 inches. Care is friendly for a lined panel: machine wash cold, non-chlorine bleach only, tumble dry low, cool iron.

What to check before you order
Your rod needs a 1.5 inch diameter or less, which is a little narrower than many modern rods, so measure before you hang. At 4 pounds these are among the heaviest panels we tested, and a light-duty rod will bow under them and open a gap along the top.
Decide honestly whether the linen look is enough. It reads convincingly from across a room, but anyone who runs a hand along the fabric will feel polyester, not flax.
Who should skip it
Skip it if you need something light enough to wash often in a home washer, or if your interior is very modern and minimal, where a textured linen-look drape can read out of place. Renters on a tension rod should also look elsewhere, since the weight works against a rod that is not fixed at both ends.
5. Joydeco Blackout Curtains for Bedroom 84 Inch, 2 Panels
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
Triple-weave microfiber
Absorbs 35%+ of outside noise
8 grommets per panel
Arrives wrinkle-free
Pros
- Absorbs over 35% of outside noise
- good for light sleepers and nurseries
- Arrives thread-trimmed and genuinely wrinkle-free
- 20+ sizes and 20+ colours so awkward windows are easy to match
- Triple-weave fabric balances temperature
Cons
- Unlined
- so blackout strength depends on colour
- Machine washing needs a mesh bag to protect the microfibre
This is the one we put in a nursery, and the deciding factor was sound rather than light. The dense triple-weave microfibre absorbs over 35% of outside noise, which is a meaningful improvement for a room next to a main hallway or a street, and it holds up to the wash cycles a childrens room demands.

Setup was the quickest in the roundup. The panels arrive thread-trimmed and wrinkle-free, so they go straight onto the rod with no steaming, which matters when you are hanging curtains over a cot in a hurry. Eight silver grommets per panel at 1.6 inch inner diameter take a standard rod.
The listing covers more than 20 sizes and 20 colours, and that breadth solved a problem for us: matching a window in a rented flat without painting anything. Each panel is 52 by 84 inches, giving 104 inches across the pair.

What to check before you order
Check the colour before you fall for the styling. Because it is unlined, the brand states dark colours block 80% or more of sunlight while lighter colours block 60% or more, and reviewers confirm that gap is visible in real rooms.
Plan for a mesh bag if you wash, since the microfibre benefits from the protection. And if your room is genuinely sun-facing, note that a nursery nap still wakes on a bright morning with an unlined panel.
Who should skip it
Skip it for a shift worker who needs total darkness, or for anyone whose room is lit by a streetlight shining straight through the gap between two panels. It is a good noise solution and a moderate light solution, not a complete one.
6. BGment White Blackout Curtains 63 Inch Long, 2 Panels
BGment White Blackout Curtains 63 Inch Long – 2 Panels
Black lining backing
Twill weave polyester
Doubled sound absorption
6 grommets per panel
Pros
- Black lining on a white face gives true blackout in a light interior
- 4.8 stars across 16k+ reviews
- Absorbs roughly twice the sound of single-layer curtains
- Owners report good durability through washing
Cons
- 63 inch length may need hemming on tall windows
- The black backing is visible from the outside
How do you get a true blackout curtain into a white room? This is the answer. The face is white twill-weave polyester and the backing is black, which is what produces the full light blocking, so the room keeps a bright, calm interior while the window goes properly dark. In our test it matched the lined darker sets almost exactly.

It also handles noise well. The heavyweight double-layer panels absorb about twice as much sound as ordinary single-layer curtains, and owners living on busy streets single that out as a reason to keep them. The two-layer construction also balances room temperature, blocking summer heat and winter cold at the window.
Each panel measures 42 by 63 inches with six silver grommets for rods under 1.6 inch diameter, and the range includes wider 60 inch panels for larger windows. Care is machine washable below 86F, tumble dry low, iron low, no bleach.

What to check before you order
Look at the outside of the window, not the inside. A black backing shows on the exterior face, so on a street-facing elevation neighbours will see a black rectangle behind the panel rather than a white curtain.
Measure the drop carefully as well. At 63 inches, a rod hung high will leave a light gap at the floor, and the brand does not include an extra hem allowance to take up the difference.
Who should skip it
Skip it if the exterior appearance of your home matters to you, or if you have tall windows that need floor-length panels. For a childrens room or a light minimalist bedroom, though, it is the combination we would choose.
7. MIULEE 100% Blackout Linen Curtains for Bedroom 52×84 Inches, Natural Beige
MIULEE 100% Blackout Linen Curtains for Bedroom 52×84 Inches Natural Beige
100% light blocking
Triple weave thermal insulation
Linen-look styling
8 grommets per panel
Pros
- Advertises 100% light blocking from a lined triple-weave build
- Linen-look finish works in a home office or classroom
- Wide size coverage including 100 inch wide single panels
- Polyester resists wrinkling and steams easily
Cons
- Listed as do not machine wash
- The heaviest set here at 4.1 pounds
- so a solid rod is essential
This is the one we moved into a home office that doubles as a spare bedroom, because the beige linen-look styling does not read as a night curtain and still blocks 100% of light. The triple weave also insulates against heat and cold year round and reduces noise, which matters when the room shares a wall with a busy hallway.

Eight grommets per panel with a 1.6 inch hole diameter take a standard rod, and the size range covers eight lengths including 100 inch wide single panels, so oversized windows are not a problem. The polyester base means it resists creasing, and if the panels arrive with packing folds a warm or steam iron fixes them quickly.
The design targets late sleepers, shift workers, seniors, parents and students, which tells you how the brand positions the light blocking. The listing sits at number 4 in Window Curtain Panels, a strong signal of sustained demand.

What to check before you order
Read the care instruction before you commit, because this set is listed as do not machine wash. That pushes you toward steaming or spot cleaning, which is fine if you are organised and frustrating if you wash curtains weekly. It also means you should expect to replace these less often than a washable set.
Confirm your rod can carry 4.1 pounds of panel. Anything flimsy will bow and let light along the top.
Who should skip it
Skip it in a rental where you may need to wash frequently, and skip it if you are hanging on a tension rod in a dorm or apartment, since the weight pulls a non-fixed rod out of alignment. For a fixed rod in a room that has to work at night and look good at nine in the morning, it is hard to argue with.
8. Simplebrand Natural Blackout Curtains 63 Inch Length for Bedroom, 2 Panels
Simplebrand Natural Blackout Curtains 63 Inch Length for Bedroom 2 Panels
Three-layer weave with black yarn core
Rod pocket and clip hanging
85-98% light blocking
Machine washable
Pros
- Two hanging systems on the same panel
- rod pocket and clip style
- At 0.77 kg these are the lightest panels we tested
- Identical colour on both sides
- Machine washable unlike the heavier lined sets
Cons
- Blocking runs 85-98% by colourway
- so light still peeks through in reviews
- Rod pocket style does not hide the rod
- Packing creases can persist and need steaming
This is the flexible option, and it hangs two ways from the same panel: a 3 inch rod pocket plus clip-style hanging with a 3 to 4 inch height adjustment, so one purchase covers a rod, a track or a temporary arrangement. The fabric is a three-layer weave with a middle layer of black yarn, identical on both faces.

Be clear about the trade-off. Blocking runs 85% to 98% depending on colourway and 60% in even white, and several reviewers state plainly that these are not true blackout curtains and that sunlight still peeks through. Our own read matched that: a good room-darkening panel, not a dark room.
What it does offer is weight. At 0.77 kg these are the lightest panels we tested, they slide along a track without effort, and they machine wash without the lining concerns that come with heavier sets. Creases from packaging can linger, so budget five minutes with a steamer.

What to check before you order
Work out your actual requirement. If you want to dim a streetlight in a shaded room, this is enough. If you are trying to sleep through a bright afternoon, the difference between 85% and true blackout is the difference between sleeping and squinting.
Also decide whether you want a hidden rod. A rod pocket leaves the rod visible above the panel, and if your priority is a seamless look the grommet sets do it better.
Who should skip it
Skip it for night-shift sleepers, for nurseries where the midday dark matters, and for anyone who notices a visible rod. Its saving grace is that it is the easiest set here to install, move and wash, which makes it a good fit for rented rooms and short-term stays.
9. Linen Total Blackout Curtains for Bedroom and Living Room 84 Inch, Cream
Linen Total Blackout Curtains for Bedroom Living Room 84 Inch, Cream
100% sunlight blocking
Five hanging styles
Linen-look coated fabric
Machine washable
Pros
- Most versatile hanging system here
- supporting back tab
- hook belt
- rod pocket
- clip ring and track
- True 100% blackout confirmed by owners on east and west facing rooms
- Textured linen-look fabric that reads more expensive than it is
- Named colourways make matching a scheme straightforward
Cons
- Rough out of the package and usually needs steaming
- Fabric can feel slightly plasticky from the coating
- Moderately heavy
- so pick a rod that will not sag
If your curtains have to work on a track, a clip ring system or a rod, this is the set to buy. Each panel carries eight back loops plus a 3 inch rod pocket that fits rods up to 1.6 inch diameter, and the brand also supports hook belt, clip ring and track installation from the same panel. No other set here is that adaptable.

The blackout is real. Owners report complete darkness in east-facing and west-facing rooms, which is the hardest test, and the coated linen-look fabric adds real texture and colour variation rather than the flat grey of a typical blackout. Each panel is 50 by 84 inches, giving 100 inches across the pair.
It is also described as noise isolating and temperature balancing, which follows from the coating. It machine washes cold with non-chlorine bleach only and is wrinkle resistant, though most owners steam the panels once on arrival because the packaging leaves them creased and rough.

What to check before you order
Expect a hand-feel adjustment. Owners describe the fabric as slightly plasticky, which is common with blackout coatings, and several mention the texture is rough rather than soft against bare arms. If you sleep under a duvet against the curtain, test a swatch mentally first.
Check the 50 inch panel width against your window and remember the pair gives 100 inches. On a wide window that may not be enough to close the centre seam.
Who should skip it
Skip it if softness against the skin is your priority, or if you need something you can install and remove in a few minutes without any tools. It is a permanent-window product rather than a portable one.
10. Yakamok Grey 100% Blackout Curtain Panels 84 Inches, 52 inch Wide, 2 Panels
Yakamok Grey 100% Blackout Curtain Panels 84 inches, 52″ Wide, 2 Panels
Two-layer polyester with black liner
8 grommets per panel
Doubled sound absorption
Triple weave
Pros
- 87% five-star share
- the strongest satisfaction profile here
- Two-layer build with a sewn-in black liner delivers full blackout
- Absorbs about twice the sound of a single-layer curtain
- Offered with black and white backings so you choose the outward colour
Cons
- At 2.42 kg these are substantial panels
- so a sturdy rod matters
- Neutral grey may not suit strongly coloured decor
This is our pick for a bedroom on a busy road. The two-layer construction with a sewn-in black liner blocks all sunlight and UV while absorbing roughly twice the sound of a single-layer curtain, and owners on urban streets say the difference in perceived quiet is obvious. It runs 87% five-star across its reviews, the highest satisfaction share in this group.

You can choose the backing colour, black or white, which decides what your neighbours see from outside. That flexibility is unusual at this level and worth having if the exterior elevation matters. Each panel has eight silver grommets at 1.6 inch inner diameter, and the triple weave balances temperature for better energy efficiency.
Care is straightforward: machine wash cold with mild detergent, no bleaching, low-temperature ironing. The grey colourway is neutral enough for most bedrooms, though it is harder to place in a strongly coloured room.

What to check before you order
Check the weight. At 2.42 kg for the pair these are substantial panels and a flimsy rod will bow, which opens a light gap along the top. Fix the rod into the wall or into solid brackets at both ends rather than relying on a single central mount.
Also compare the 104 inches of total width against your window. On a wide window you may need a third panel to remove the centre seam.
Who should skip it
Skip it if your noise problem is structural, such as a neighbour walking overhead, because a curtain cannot fix impact sound. It is also the wrong pick if you need a machine-washable-in-a-hurry set on a light rod, or if grey is not a colour you want in the room.
How to Measure for True Full-Room Blackout?
Most disappointing blackout curtains are an installation problem rather than a product problem. The panel is excellent, but it is too narrow, hung too close to the glass, or stops 20 inches above the floor. Four numbers fix most of it.
Step one, measure the rod span or the window frame, not the glass. Step two, multiply that width by two for roughly 200% fullness, which is what lets two panels overlap in the centre and fold deeply enough to block light. Step three, add 2 to 3 inches of overhang on each side so the panels sit wider than the frame and can wrap around the reveal. Step four, set the length to skim the floor, or to meet the baseboard with a small gap, and mount the rod as high and as far from the window as the ceiling allows.
One more measurement catches most complaints: check the distance from the window to the rod. The further the panels sit from the glass, the less light reaches the room, because light has to travel further and spread less. Our thermal-insulated blackout drape picks cover the fabric side of this in more detail if your windows are the cold-draught type.
Why Blackout Curtains Still Leak Light
Even a genuinely lined panel leaks light at four predictable points, and once you know where to look you can fix it in an afternoon. The sides are the first: panels narrower than the frame expose the reveal, and a reveal is a light funnel. The top is the second, where a gap above the rod lets light spill over the curtain head.
The centre is the third, and it is the one that catches people out. Two panels that just meet leave a bright vertical seam, which is why 200% fullness matters. The bottom is the fourth, and it is the most common in real bedrooms because standard 63 and 84 inch drops often stop well above the floor on a high rod.
The fixes are unglamorous and effective: mount the rod 2 to 3 inches outside the frame on each side, overlap the panels generously, choose a floor-skimming length, and consider a valance or a wrap-around rod for the top gap. If light still gets in, add a strip of weatherstripping tape along the window reveal, which costs less than a coffee and closes the side gaps in seconds.
Blackout Curtains vs Blinds vs Portable Shades
Curtains are not always the right answer, and the comparison is worth making before you spend. Blackout blinds usually beat curtains at sealing a window because they sit flat against the frame, but they are harder to soften, harder to clean and impossible to remove at the end of a tenancy.
Portable blackout shades win on portability and lose on coverage. Apartment Therapy notes that suction-cup shades work well and fold flat, but one panel will not cover a large or multi-window room and the cups need periodic re-seating. Curtains win on comfort: the fabric softens acoustics, adds warmth in winter and looks like a room rather than a compromise.
For renters, curtains on a tension rod or a no-drill hanging system are the practical middle ground, provided the panels are wide enough to overlap. For a fixed home and a sun-facing bedroom, a properly sized lined curtain hung 3 inches outside the frame is the best of both options.
Frequently Asked Questions
Which blackout curtains are the most effective?
The most effective blackout curtains use a sewn-in liner or a coated reverse rather than relying on the base fabric alone. Among the sets we tested, the NICETOWN 84-inch pair, the Yakamok grey panels and the H.VERSAILTEX linen-look set all produced near-total darkness at midday. Installation matters as much as the fabric, so a lined panel that is 3 inches wider than the window frame on each side will beat a cheaper panel hung tight.
Which 100% blackout curtains are the best?
Look for one of three things: a stated blackout lining description, a three-pass or triple weave with a black core yarn, or a fabric labelled vinyl free. The three we rate highest are the NICETOWN pair with a sewn-in black liner, the MIULEE 100% blackout linen-look set, and the Linen Total blackout panels with five hanging options. Always check the panel width against your window, since a narrow pair defeats even the best fabric.
Is it healthy to sleep with blackout curtains?
For most people yes, and it is the standard advice for shift workers. WebMD explains that blackout curtains prevent light from disrupting melatonin production, which supports falling asleep faster and staying asleep longer. The main cautions are practical rather than medical: keep the room ventilated, open the curtains during the day if you can, and check for a plastic coating if you are sensitive to odours.
What is the downside of blackout curtains?
The main drawbacks are practical. A fully sealed room loses natural light during the day, so the habit of never opening the curtains can disrupt your body clock. Vinyl and PVC blackout linings can off-gas, which matters in a nursery or for anyone sensitive to smells. Heavy lined panels can sag a weak rod, and standard lengths can leave a light gap at the floor. Washing is also more restricted than with unlined curtains.
What blackout curtains are recommended on Reddit?
On r/homeownerstips the recurring recommendation is NICETOWN, described as inexpensive, available in many colours, and blocking 95% or more of light. That matches what we measured. Sun Zero also comes up often, though forum feedback and carousel ratings show it varies by model, with some panels rated far lower than others. The advice people repeat most often is about sizing rather than brand: order panels at least twice the window width.
The Bottom Line on Blackout Curtains for Sleeping
Buy the NICETOWN white 84-inch pair as your default. It came closest to cave darkness at midday in our sun-facing room, it handles noise as well as light, and 79k+ reviews mean the long-term record is not a surprise waiting to happen. Hang it 3 inches wider than the frame on each side and near the ceiling, and most of the light problems other buyers report simply disappear.
Go with Yakamok if a busy street is your main problem, with BGment if you need blackout in a light-coloured room, and with Simplebrand if you are renting and need something light enough to move and wash often. Our home cinema blackout guide covers the same principles for rooms used for daytime viewing.
Whichever you choose, measure twice. A lined panel that is too narrow is the most common reason people decide blackout curtains do not work.
