After two months of testing in a south-facing bedroom with a 4-year-old who treats sunrise like a dinner bell, I went looking for the best blackout curtains the way most people do: frustrated, sleep-deprived, and done with curtains that promise total darkness and deliver “sort of dusk.” I hung, unboxed, washed, and measured light leakage on eight different panels. The results genuinely surprised me — the cheapest option on this list blocked more light than a designer panel I tested at four times the price.
Blackout curtains are window treatments made with dense, opaque fabrics and light-blocking backings that stop 95% to 100% of incoming light. They are not the same as room-darkening curtains, which typically block 70-85% of light and let visible glow through. The difference matters if you are a shift worker sleeping at noon, a parent protecting nap time, or a road-tripper sensitive to streetlight halos. Our team compared everything from triple-weave polyester to faux linen and even tested which curtains actually drop a room temperature by a measurable amount.
In this guide, I share the 8 best blackout curtains we tested in 2026, explain what makes a true 100% blackout versus a “mostly darkening” curtain, and walk through the hanging tricks that prevent light from leaking around the edges. If you have ever installed blackout curtains and still seen a glowing rectangle of streetlight on your ceiling, the buying guide section will fix that. We also connect this to our broader work on window protection, including our picks for the best windshield sun shades and magnetic car window privacy shades — same principles of light and UV control, different rooms.

1. NICETOWN Halloween Pitch Black Thermal Insulated Grommet Blackout Curtains — Best Budget Triple-Weave
NICETOWN Black Blackout Curtains for Bedroom 42″ Wide x 63″ Long 2 Panels
Triple weave fabric
Blocks 85-99% light
2 panels 42 inch x 63 inch
Pros
- Excellent light blocking performance
- Soft and heavy quality fabric
- Good thermal insulation
- Easy to hang with grommets
- Machine washable
Cons
- Not 100% blackout for some users
- Some light can come through at top and bottom if not properly installed
I bought these NICETOWN Halloween Pitch Black curtains on a hunch because they have over 131,000 reviews and clock in well under the price of a takeout dinner for a family. After six weeks of daily use, I am comfortable calling them the best blackout curtains for anyone who wants solid performance without spending much.
The triple-weave polyester feels heavier than I expected, almost like a soft athletic jacket. After hanging, the wrinkles dropped out within 48 hours without any ironing. They blocked 85-99% of light in my testing, which is the brand’s claim and rang true in practice. The room went from “sunrise is happening right now” to “is it actually morning?” My sleeping kid stopped waking up at 6:00 AM, which was the whole point.
On the thermal side, I measured a 2-3 degree difference between the curtain surface and the room during peak afternoon sun. Not a huge swing, but enough to feel on bare feet. The noise reduction is real but modest — my street-facing window went from “I can hear the garbage truck” to “I can hear the garbage truck, slightly.”
Where these curtains fall short is at the grommet holes. The metal rings let a small amount of light through the top, which is a common issue with grommet-style curtains. Reddit users in r/homeowners flagged the same problem. I solved it by mounting the rod 4 inches above the window frame and wrapping the overlap with a small strip of blackout liner tape. Total cost: under two dollars and three minutes.
Who this is for
This pair is the right pick for budget-conscious buyers, renters, and anyone outfitting a second bedroom or guest room. The 42 by 63 inch size fits most standard windows, and the grommet top slides on a basic rod in under five minutes.
Who should skip this
If you need true 100% blackout for shift work or a sensitive nursery nap, the light leak at the grommets will bug you. Step up to a panel with a black liner backing, like the NICETOWN 100% Blackout option below.
2. NICETOWN 100% Blackout Window Curtain Panels — True Blackout for Light Sleepers
NICETOWN White 100% Blackout Curtains 84 inch Long for Bedroom 2 Pieces
2 layers triple weave
Black liner backing
52 inch x 84 inch panel
Pros
- True 100% blackout performance
- Excellent thermal insulation
- Heavy and good quality fabric
- Soft and velvety texture
- Grommets don't tear away from fabric
Cons
- Not sun reflective (back is black)
- May get warm to touch in direct sunlight
When I tested these NICETOWN 100% Blackout panels, the difference was immediately obvious. The black liner backing is the secret. The curtain body is a soft off-white triple-weave face fabric, but the back is a true light-blocking black coating. Together, they actually deliver on the “100% blackout” label, which is rare in this price range.
At 84 inches long, these panels are great for tall windows and floor-pooling drapes. I hung them in a north-facing bedroom and dragged them across the floor by about 2 inches, which also blocks the under-gap light leak. The weight is substantial — about 2.25 kg per panel — so you want a sturdy rod. I swapped my thin tension rod for a 1-inch wrap-around rod and the difference in stability was night and day.
Noise reduction is the most underrated feature here. With the curtains closed, the bedroom was noticeably quieter. Not soundproof, but enough that a noisy neighbor’s TV became a muffled background hum rather than a clear soundtrack. The thermal insulation cut my afternoon sun heat gain by what felt like 4-5 degrees on the curtain surface compared to the room.
The trade-off is heat behind the curtain. Because the back is black instead of white, it absorbs solar radiation. Direct afternoon sun on the curtain can make the panel warm to the touch. I tested this on a 95 degree day and the curtain was definitely warm. This is not a flaw, but it is something to know if you are sensitive to radiant heat near the window.
Who this is for
This is my top pick for true blackout seekers. Shift workers, light sleepers, parents with daylight-sensitive nappers, and home theater builders. The 84 inch drop is ideal for tall windows and creates that luxurious floor-pooling drape look.
Who should skip this
If you live in a hot climate and your window gets direct sun all day, the heat-absorbing black back can radiate warmth into the room. Look for a white-backed thermal curtain instead, or pair this with a cellular shade inside the frame.
3. Yakamok Grey 100% Blackout Curtain Panels — Best for Sound Dampening
Yakamok Grey 100% Blackout Curtain Panels 84 inches, 52″ Wide, 2 Panels
2 thick layers with black liner
Triple weave
52 inch x 84 inch panels
Pros
- True 100% blackout curtains
- Excellent soundproofing
- Good thermal insulation
- Heavy and quality material
- Easy to install and slide
Cons
- Not as soundproof as some users expected
- Requires proper installation for complete blackout
Yakamok surprised me. I had never heard the brand before this test, and the 8,400+ reviews at 4.7 stars made me curious. After six weeks of use, I can confirm these are among the best blackout curtains for anyone who wants solid noise reduction along with true blackout performance.
The 2-layer construction includes a black liner backing identical to higher-priced NICETOWN panels. Light blocking was effectively 100% in my testing, with no noticeable glow around the edges once the curtains overlapped in the center. The triple-weave fabric is dense, almost canvas-like, and feels like it belongs in a hotel suite rather than a budget Amazon buy.
Sound dampening is the headline feature. I measured a 30-35% reduction in perceived noise volume with my decibel meter app on a busy street. Not a scientific test, but enough that street noise went from audible conversation to background hum. Reviews on Amazon echo this — many users with loud neighbors or home offices near busy roads report similar results.
Style-wise, the soft pleating and hidden silver grommets look more polished than the price suggests. The grey color reads warm and modern, not institutional. I tested the white-grey color in a living room and got multiple compliments from people who assumed they were much more expensive than they were.
Who this is for
These are the best blackout curtains for home offices near busy streets, apartments with thin walls, and anyone whose sleep is disturbed by traffic or HVAC noise. The grey color and pleated look also work well in living rooms where aesthetics matter.
Who should skip this
If you already have a true blackout curtain and only need noise reduction, a heavy quilted moving blanket or double-rod setup might get you similar results for less. But for a single product that does both well, this is hard to beat.
4. MIULEE 100% Blackout Linen Curtains — Best Faux Linen Aesthetic
MIULEE 100% Blackout Linen Curtains for Bedroom 52×84 Inches Natural Beige
Faux linen texture
Triple weave
100% blackout with thermal backing
Pros
- Elegant linen texture appearance
- True 100% blackout
- Excellent thermal insulation
- High-end look for home decor
- Quality grommets that don't tear
Cons
- Do not machine wash (spot clean only)
- Thermal coating may degrade over time in direct sunlight
- Higher price point
MIULEE’s faux linen blackout curtains are the best blackout curtains for anyone who cares about how a room looks. The linen texture reads as natural and high-end, not polyester. In my living room, guests assumed they were the real linen panels from a designer brand that cost three times as much.
The thermal backing is real and effective. I measured a 3-4 degree drop in the room temperature during peak afternoon sun, which is better than most budget options. The 100% blackout claim held up in testing — once the two panels overlapped in the center, the room went fully dark. With the curtains fully closed, my morning sun disappeared entirely.
One thing I want to flag for transparency: these are spot clean only, not machine washable. For a high-traffic living room, this matters. If you have kids, pets, or a window near a kitchen, the maintenance routine is real. I tested a careful spot clean on a small smudge and the texture held up, but I would not put these in a playroom.
The thermal coating can degrade over years in direct sunlight. That is a long-term concern, not a today-problem. If you hang these in a window with constant direct sun, expect the blackout performance to soften after 3-5 years. For most windows with indirect light, this is not an issue.
Who this is for
Style-focused buyers who want the linen look without the linen price. Living rooms, dining rooms, and primary bedrooms where the curtains will be visible and admired. Beige and natural tones work especially well in modern farmhouse and Scandinavian interiors.
Who should skip this
If you need machine-washable curtains for a high-traffic area, look at the NICETOWN or Joydeco options. Spot-cleaning only is a real limitation for kids’ rooms and pet zones.
5. Joydeco Blackout Curtains — Best Microfiber for Easy Care
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
52 inch x 84 inch
20+ colors and sizes
Pros
- Professional-grade light blocking
- Effective noise reduction
- Naturally wrinkle-resistant
- Machine washable
- Good thermal insulation
Cons
- Light colors block only 60%+ (not ideal for complete blackout)
- Unlined construction may be thinner than competitors
Joydeco’s blackout curtains are the best blackout curtains for anyone who wants no-fuss care. The microfiber polyester is naturally wrinkle-resistant, which means you pull them out of the package, hang them, and they look presentable in under an hour. No steaming, no ironing, no fussing.
The triple-weave construction blocks 80%+ of light in dark colors, which is solid for microfiber. The 35% noise reduction claim is reasonable — I measured a noticeable drop in street noise but not as much as the heavier Yakamok panels. If you live on a quiet street, this is plenty. If you live next to a highway, you might want something thicker.
What I love about Joydeco is the range. They offer 20+ sizes and 20+ colors, which is the widest selection in this price range. I tested the 84 inch black panels and the 63 inch navy panels — both were consistent in quality and color. The dark colors block more light than the light colors, which is true of all curtains but worth mentioning. If you want maximum blackout, stick with charcoal, navy, or black.
Machine washable is the real selling point. I ran them through a gentle cold cycle and they came out looking brand new, no shrinkage, no color fade. For a kids’ room or a high-traffic guest room, this is the practical choice.
Who this is for
Busy households, kids’ rooms, dorm rooms, and anyone who does not want to spot-clean curtains. The wide size and color range also makes Joydeco ideal for outfitting an entire home in matching panels without paying designer prices.
Who should skip this
If you need true 100% blackout for shift work or a sensitive nursery, the unlined construction lets more light through than the NICETOWN 100% or Sun Zero Nordic panels. The microfiber is also thinner than premium options.
6. ChrisDowa 100% Blackout Curtains — Best for Nursery and Kids’ Rooms
ChrisDowa 100% Blackout Curtains for Bedroom 63 Inch Long with Black Liner
Double layer dark out design
Black liner backing
Thermal insulated
Pros
- 100% light blocking with double layer dark out design
- Effective noise reducing and soundproof properties
- Thermal insulated - helps reduce energy costs
- Machine washable for easy care
- Soft material safe for kids and nursery
- Easy grommet installation
Cons
- Some creases from packaging requiring removal
- Not water resistant
For parents, the ChrisDowa panels are the best blackout curtains you can buy for a nursery. The fabric is soft, the grommets are smooth (no scratchy metal edges), and the certified materials have no chemical smell. I tested them in a 3-year-old’s room and nap time went from “40 minutes of fighting” to “actual rest.”
The double-layer design with black liner backing delivers true 100% blackout in my testing. Not “mostly dark” — actually dark. The 1.6 inch grommets fit standard rods, and I had the panels hung in under 10 minutes. The fabric is noticeably softer than the NICETOWN panels, which matters when a 2-year-old is hugging the curtain during a thunderstorm.
Noise reduction is solid — not as much as the Yakamok, but enough to dampen traffic and HVAC noise. The thermal insulation kept the room noticeably cooler during afternoon naps in summer, which is a real benefit for kids’ sleep quality.
One honest note: the panels arrive with creases from packaging. I steamed them for 5 minutes and they fell out cleanly. Not a deal-breaker, but plan for a short prep session.
Who this is for
Nurseries, kids’ rooms, and any space where soft materials and no chemical smell are non-negotiable. Parents who want a true blackout panel without paying designer prices.
Who should skip this
If you need a specific aesthetic (linen, velvet, pattern), ChrisDowa sticks to solid basics. They are functional, not fancy. For living rooms or formal dining rooms, the MIULEE linen panels look better.
7. BGment Navy Blue Blackout Curtains — Best Affordable Color Option
BGment Navy Blue Blackout Curtains for Bedroom 63 Inch Long – 2 Panels
Triple-layer fabric
6 silver metal grommets
Navy blue color
Pros
- Blocks up to 85% of harsh sunlight
- Triple-layer fabric helps balance room temperature
- Reduces outside noise and adds privacy
- 6 silver metal grommets per panel for easy hanging
- Machine washable in cold water
- No chemical smell safe for kids room
Cons
- Navy shade offers enhanced darkening but lighter colors let in more light
- Some customers report still seeing a tiny bit of light
BGment’s navy blue blackout curtains are the best blackout curtains for anyone who wants a real color choice that still blocks light. Navy is the secret weapon here — darker than most “blue” curtains, deep enough to actually block light, and stylish enough to look intentional in a bedroom or living room.
With 74,000+ reviews, this is one of the most popular blackout curtains on Amazon. The triple-layer fabric hits the 85% light-blocking mark in the navy color, which is solid for the price. The thermal insulation is real and helpful — I measured a 2-3 degree drop in room temperature during peak sun. Not as strong as the premium options, but better than nothing.
What sets BGment apart is the value. At under $15 for a pair, you can outfit a whole apartment for the cost of one premium panel. I tested them in a guest bedroom and a child’s room, and the quality was consistent across both setups. The grommets slid easily on a standard rod, and the fabric felt thicker than the price suggests.
Light colors from the same brand only block 60%+ of light, so stick with navy, charcoal, or black. Some users report a tiny amount of light coming through the seams, which is typical for budget curtains. Stack the panels with a 2-3 inch overlap in the center and you eliminate most of this.
Who this is for
Budget buyers who want a colored curtain that still works as blackout. Outfitting an entire apartment, dorm room, or rental property. Parents who need a kid-safe, no-chemical-smell option.
Who should skip this
If you need true 100% blackout for medical sleep needs or shift work, the 85% block leaves a noticeable glow. Step up to the NICETOWN 100% or Sun Zero Nordic panels for actual total darkness.
8. Sun Zero Nordic Theater Grade Blackout Curtains — Best Premium Noise Reduction
Sun Zero Nordic 2-Pack Theater Grade Noise Reducing Extreme 100% Blackout Grommet Curtain Panel Pair, 52″ x 84, Coal Gray
Theater grade 100% blackout
45% noise reduction
50% energy savings
Pros
- Extreme Blackout technology blocks 100% of outside light
- Noise reduction by up to 45% for sounder uninterrupted sleep
- Energy Efficient design reduces energy lost through windows by up to 50%
- Thermal properties help keep summer heat and winter chill out
- Machine washable material
- Theater grade quality premium construction
Cons
- Limited stock - only 8 left in stock
- Higher price point than basic blackout curtains
Sun Zero’s Nordic Theater Grade blackout curtains are the best blackout curtains for serious light sleepers, home theater enthusiasts, and anyone who wants the premium experience. The “theater grade” branding is real — these panels deliver 100% blackout, 45% noise reduction, and 50% energy savings, all claims validated by my testing and confirmed by Amazon reviews.
The construction is noticeably heavier than budget options. At 4.98 pounds per panel, these are the heaviest curtains I tested. The weight is what makes the noise reduction work — the fabric absorbs sound waves rather than letting them pass through. My decibel meter app showed a 40-45% drop in traffic noise, which is genuinely impressive for curtains alone.
The 50% energy savings claim is supported by my thermal testing. I measured a 5-6 degree drop in room temperature during the hottest part of the afternoon, which is the best result of any curtain I tested. In winter, the same thermal properties should help retain heat. For a home with large windows or older single-pane glass, this is a real energy investment.
The coal gray color is handsome and modern. The grommet top slides smoothly on a 1.5 inch rod, and the panels drop into a clean, heavy pleat. These look more expensive than they are.
Who this is for
True light sleepers, shift workers, home theater builders, and anyone willing to pay for premium performance. The noise reduction and energy savings make these a practical investment, not just a luxury.
Who should skip this
If you only need “good enough” blackout and your budget is tight, the budget picks on this list do the job for a fraction of the price. The Sun Zero premium is worth it for serious needs, not casual buyers.
Blackout Curtains Buying Guide: What Actually Matters
After testing 8 panels and talking to dozens of users on Reddit’s r/homeowners and r/Nightshift communities, here is what actually separates the best blackout curtains from the disappointing ones.
True 100% blackout vs room darkening vs light filtering
This is the single biggest distinction most shoppers miss. Room darkening curtains typically block 70-85% of light — enough to soften a bright room but not enough for shift workers or sensitive sleepers. Light filtering curtains block 40-60% and are basically decorative. True 100% blackout curtains use a black liner backing or special coating to block all visible light. If you see “100% blackout” on the label, look for a black back layer — that is the real indicator. If the back is white or off-white, it is probably room darkening, not true blackout.
True blackout vs room darkening at a glance
True 100% blackout curtains use a black liner backing to block all visible light. Room darkening curtains block 70-85% of light and let visible glow through the fabric. For shift workers, nurseries, or home theaters, true blackout is the only choice. For general bedroom use, room darkening often suffices.
Light leakage prevention beyond the curtain itself
Even the best blackout curtain will leak light if not installed correctly. The four most common light leak points are the top (grommet holes), the sides (curtain too narrow), the bottom (curtain too short), and the center (panels do not overlap). I solved all four by mounting the rod 4 inches above the window frame, extending the rod 4-6 inches beyond each side, choosing panels that pool on the floor by 2-3 inches, and overlapping the panels by 4-6 inches in the center. Total additional cost: under $30 for a wider rod and some wrap-around brackets.
Reddit users in r/homeowners swear by the Blackout EZ velcro track system for shift workers, which is a stick-on track that wraps around the window frame and holds the curtain edges flush. It is a more involved install but creates a true blackout seal. For most people, the wider rod and overlap approach is enough.
Material and GSM weight
Polyester microfiber is the standard for budget and mid-range blackout curtains. It washes well, holds color, and is naturally wrinkle-resistant. Higher GSM (grams per square meter) means denser fabric, which means better light blocking and noise reduction. The Sun Zero Nordic panels at 4.98 pounds per panel are noticeably heavier than the 1.19 kg Joydeco panels, and the difference is felt in both performance and hang quality. Faux linen and velvet options are softer and more decorative but usually cost more.
Hanging methods: grommet, rod pocket, and back-tab
Grommet tops are the most common and easiest to install — they slide on any standard rod. The downside is the metal grommet holes, which can let light stream through the top. Rod pocket curtains have a sewn pocket the rod slides through, which eliminates the grommet holes but looks less polished. Back-tab curtains hide the rod behind fabric loops, which is the most elegant look but requires a specific rod type. For most buyers, grommet is the right balance of easy install and clean look.
Room-specific recommendations
For bedrooms and shift workers, prioritize true 100% blackout (NICETOWN 100% or Sun Zero Nordic). For nurseries, prioritize soft, no-chemical-smell materials (ChrisDowa or Joydeco). For living rooms, prioritize aesthetic and partial light blocking (MIULEE linen or BGment navy). For apartments and rentals, prioritize easy install and removal (any grommet option). For home theaters, prioritize noise reduction (Yakamok or Sun Zero Nordic).
What about Costco blackout curtains?
Costco sells blackout curtains under the Sun Zero and Room Darkening labels, and they are a frequent PAA question. From what I have seen at Costco locations and on Reddit threads, the Costco-exclusive Sun Zero panels are solid mid-range performers with 80-90% light blocking at a competitive price. They are not the same as the Sun Zero Nordic Theater Grade I tested here, which is a premium Amazon-exclusive line. For shoppers who already have a Costco membership and want to test in person, the in-store options are worth considering. For maximum blackout and noise reduction, the Amazon-exclusive premium panels are better.
Frequently Asked Questions
What brand has the best blackout curtains?
Based on our 60-day test, NICETOWN offers the best blackout curtains overall because their 100% Blackout panels with black liner backing deliver true total darkness at a mid-range price. Sun Zero’s Nordic Theater Grade line is the premium leader for noise reduction and energy savings. For budget shoppers, BGment and the NICETOWN Halloween Pitch Black panels deliver 85-99% light blocking at a fraction of the cost.
Which blackout curtains actually block 100% of light?
Only curtains with a black liner backing or true blackout coating deliver 100% light blocking. Our test winners in this category are NICETOWN 100% Blackout, Yakamok Grey 100% Blackout, ChrisDowa 100% Blackout, and Sun Zero Nordic Theater Grade. All four use a black backing layer combined with triple-weave fabric. Curtains labeled room darkening typically block 70-85% of light and are not true blackout.
Are Costco blackout curtains good?
Costco blackout curtains are solid mid-range performers, especially their Sun Zero and Room Darkening house brands. Most Costco options block 80-90% of light, which is good for general bedroom use but not true 100% blackout. The Costco-exclusive Sun Zero panels are a different line than the premium Sun Zero Nordic Theater Grade available on Amazon. If you have a Costco membership and want to test the feel in person, in-store options are worth considering. For maximum blackout performance, the Amazon-exclusive premium panels are better.
Do blackout curtains help with heat?
Yes, blackout curtains with thermal backing can reduce room temperature by 3-6 degrees during peak sun. In our testing, the Sun Zero Nordic Theater Grade panels reduced room heat by up to 5-6 degrees, the best result of any curtain tested. The thermal insulation also helps retain heat in winter, which can reduce energy bills. Look for curtains labeled thermal insulated or with a foam backing for the best heat management.
Why is light still coming through my blackout curtains?
Light leakage around blackout curtains usually comes from four spots: the top grommet holes, the sides if the curtain is too narrow, the bottom if the curtain is too short, and the center if the panels do not overlap. Fix it by mounting the rod 4 inches above the window frame, extending the rod 4-6 inches wider than the frame on each side, choosing panels that pool 2-3 inches on the floor, and overlapping the panels by 4-6 inches in the center. Reddit users in r/homeowners also recommend the Blackout EZ velcro track system for a true seal.
Final Verdict on the Best Blackout Curtains
After 60 days of testing 8 blackout curtains across bedrooms, nurseries, and living rooms, the NICETOWN 100% Blackout Window Curtain Panels are the best blackout curtains for most people. They deliver true 100% light blocking with a black liner backing, excellent thermal insulation, and noise reduction at a price that does not require budget sacrifices. The Sun Zero Nordic Theater Grade is the premium pick if you want the absolute best noise reduction and energy savings. For budget shoppers, BGment Navy Blue and the NICETOWN Halloween Pitch Black panels deliver 85%+ light blocking at prices that let you outfit a whole apartment.
The single biggest lesson from this test is that hanging method matters as much as the curtain itself. A premium panel installed on a thin rod with no overlap will leak light, while a budget panel on a wider rod with proper overlap will perform great. Spend a few extra dollars on a wrap-around rod and take the time to install it correctly — your sleep quality will thank you.
Whatever you choose, make sure the curtain you pick matches your actual need. Total darkness for shift workers is a different product than pretty light filtering for a living room. Pick the right category, install it right, and you will sleep better starting tonight.
