You want a room that actually goes dark when you close the curtains — not one that just dims the worst of the glare. A true blackout curtain blocks up to 100% of sunlight, letting you sleep past sunrise and keeping west-facing rooms cooler in the afternoon.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Finding the best curtains for blackout means reading beyond the bold claims and focusing on panel width, grommet size, and just how much light actually gets blocked.
Our Picks at a Glance



How To Choose The Best Curtains For Blackout
A true blackout curtain uses a dense, lined weave that physically blocks light rather than merely filtering it. The backing and weave are what matter: a densely woven lining stops photons, while a light-filtering fabric only scatters them.
Panel Width vs. Window Width
Measure your window width and double it to ensure full folds and no edge gaps. A single pair of 50-inch panels covers about 100 inches of width, which is ideal for a standard 48-inch window because the extra fabric creates those nice, full folds. If you pick panels exactly the width of your window, light will slip in around the edges and you’ll see the gaps.
Grommet and Rod Compatibility
Check the grommet inner diameter (usually 1.6 inches) against your rod’s thickness before buying. Most curtains you’ll find use a 1.6-inch inner diameter, which fits standard rods up to 1.5 inches. If your rod is thicker, the curtain might catch or bunch instead of sliding smoothly.

In‑Depth Reviews
1. FMFUNCTEX Blue Blackout Floral Curtains
Our pick — over 4.5★ from 750+ verified ratings; the strongest balance of quality and price.
A floral panel that delivers complete darkness without asking you to give up style.
What wins people over here is the light blocking — it sits at the top of the discussion with nearly 100 owners calling it out. The dense weave plus a lined backing knocks out up to 100% of sunlight, which is exactly what you want when a west-facing window turns your living room into a sauna every afternoon.
Buyers report that the material feels heavy and thick, almost like satin, which is why the same panel that kills the glare also keeps the room cooler and softens outside noise. Each panel measures 50 inches wide by 84 inches long, and the combined 100 inches of coverage means you get proper folds instead of a stretched, flat sheet.
The 8 silver grommets per panel have a 1.6-inch inner diameter, so they fit most standard curtain rods and slide smoothly when you open and close them. Quality is the second most-praised trait, and owners mention the fabric holds up to washing — just use cold water, no bleach, and tumble dry low to keep the plum blossom print looking fresh.
What Wins Owners Over
- True 100% blackout with a lined, woven backing
- Heavy, soft material that feels more expensive than it is
- Prints like plum blossom suit farmhouse and cottage decor
What to Weigh
- Each panel is 50 inches, so super-wide windows need extra sets
- The floral print won’t fit every minimalist room
Reach for this if: you want a pretty curtain that actually performs — this one is the crowd favorite at 4.8 stars across 700+ owners.
Look elsewhere if: your room calls for a plain, solid panel with zero pattern.
2. NICETOWN Thermal Insulated Curtains
The budget icon that blocks light and cool air with a triple-weave trick.
This is the one with a massive following — it holds a 4.6-star rating across more than 130,000 owners, which makes it the safest bet in this entire list if you just want something that works. Its triple-weave, three-layer fabric blocks 85%-99% of light and UV rays without a separate liner.
The biscotti beige color is popular because it looks expensive, but dark colors do the heavy lifting; the darker the shade you pick, the closer you get to that 99% figure. Owners mention it keeps a room pitch black, and the 1.6-inch grommet rings slide easily onto standard rods.
At 42 inches wide by 63 inches long, these are on the shorter and narrower side, so they suit smaller windows. One owner mentioned trying a few curtains for an east-facing master bedroom before this one finally worked — the flow and fullness are what do the job.
The Strengths
- Proven track record with a massive owner base
- Triple weave blocks 85%-99% of light and UV rays
- Soft, heavy fabric that looks premium
The Limitations
- 63-inch length leaves large windows exposed
- Lighter colors block less light than darker ones
Best for: buyers who want a proven performer and don’t need the tallest panels.
Think twice if: your window is extra wide or you want true 100% darkness — this one lands at 85%-99%.
3. MIULEE 100% Blackout Linen Curtains
Linen texture that hides a 100% blackout core and offers three hanging styles.
This panel tricks the eye: it looks like a soft, natural linen drape, but it’s actually 100% polyester woven tight enough to plunge a room into total darkness. Light blocking is the most-praised aspect, with over 100 owners confirming it works against street light and direct sun alike.
What makes it different from the grommet-heavy competition is the versatility — you get Back Tab, Rod Pocket, and Pinch Pleat hanging methods, plus 24 metal hooks for the pleated look. That means you can change the style without buying new curtains.
Each panel is 42 inches wide by 84 inches long, while the 52-inch BGment panels are wider. A few customers note tiny pinholes near the stitching that let in minuscule dots of light, but the general consensus is the look and insulation make it worth it.
Why It Stands Out
- True 100% blackout with a linen-textured face
- Three hanging styles and 24 metal pleat hooks included
- Thick fabric that helps keep rooms cool
The Trade-Off
- Narrower 42-inch panels need more sets for wide windows
- Occasional needle holes near the seams let in tiny light dots
Ideal for: decor-conscious buyers who want an elegant, non-plastic look with real blackout performance.
Skip if: you need the widest possible panels for a large picture window.
4. BGment Black Blackout Curtains
A wide 52-inch panel that covers big windows and blocks 85%-99% of sunlight.
If your window is wider than standard, measure this one first. Each of the two panels is 52 inches wide by 84 inches long, giving you 104 inches of total coverage; the MIULEE panels are 42 inches wide, so you get fewer gaps and fuller folds on a large frame.
As a black curtain, it sits at the top of the light-blocking range, hitting that 85%-99% mark because darker colors simply work better. Buyers are upfront that it’s not a perfect “proper blackout” curtain, but it gets a room plenty dark for the money, and it helps insulate against summer heat.
The 8 silver grommets per panel have a 1.6-inch inner diameter and slide smoothly, and the machine-washable polyester holds its shape and color after multiple washes. It’s a straightforward, no-nonsense pick for late sleepers and shift workers.
What You Get
- 104 inches of total width from two 52-inch panels
- Black color boost the 85%-99% light blocking
- Soft after washing, resists wrinkles, easy for kids to open
Keep in Mind
- Not quite total blackout — a sliver of light can sneak through
- White backside shows from certain angles
Choose this if: you need wide coverage on a budget and can live with 99% darkness rather than 100%.
Pass if: your room must be absolutely pitch black, like for photo work or severe light sensitivity.
5. KOUFALL Linen Blackout Curtains
A rustic cream linen look that turns day into night for night-shift workers.
This is the pick for the boho-farmhouse aesthetic, with a cream-beige linen texture that reads cozy rather than clinical. The two panels measure a generous 52 inches wide by 84 inches long, so the pair spans 104 inches and fits wide windows without awkward stretching.
The lined backing is where the blackout happens — it blocks 100% of sunlight and UV rays, and buyers confirm it turns the room pitch black when fully closed. Night-shift workers specifically call it out as a lifesaver for sleeping during the day, and the fabric helpfully cancels around 50% of outside noise.
The honest catch is the break-in period: a few owners mention a chemical smell for the first days and creases that fade over about a week. The wrinkles steam out easily, and the durable non-plastic backing is the reason the light stays out.
What Shines
- 100% blackout with a durable lined backing
- Wide 52-inch panels give 104 inches of coverage
- Rustic faux-linen look with a cozy farmhouse feel
What to Expect
- New-curtain smell for the first few days
- Packaging creases take about a week to relax
Reach for it if: you want a textured, warm look that still delivers true darkness for daytime sleep.
Consider the alternative if: you’re sensitive to odors — the initial smell is the main complaint.
6. FMFUNCTEX 100% Blackout Beige Curtains
The rare beige that delivers true blackout — and feels heavy and premium doing it.
Beige is usually the color that fails the blackout test, so this one impresses because it holds its own at 100%. The triple-weave double-layer fabric is thick enough to block light yet silky soft, with quality being the first thing buyers notice.
Quality is actually the most-discussed aspect here, with over 70 owners praising the construction, and the blackout itself right behind it. The 52-inch by 84-inch panels give solid coverage, and the material has no chemical smell, making it a safe choice for a kid’s room or nursery.
The 1.6-inch grommets slide on standard rods, and the 0.25-inch thickness is what gives it that heavy, expensive drape that also blocks heat. Buyers explicitly mention it makes a room look more expensive and helps with energy bills, with wrinkles dropping out quickly thanks to the weight.
The High Points
- True 100% blackout even in a light beige shade
- Heavy 0.25-inch triple-weave fabric with a soft touch
- No chemical smell, safe for nurseries
The Fine Print
- Heavier fabric needs a sturdy rod
- Warm iron or steam needed to remove packaging creases
Pick this if: you want a light neutral color without sacrificing any darkness — a rare combination.
Look elsewhere if: you’re mounting on a flimsy tension rod that can’t take the weight.
7. Joydeco Velvet Blackout Curtains
Velvet opulence that smothers light and keeps the cold air out.
If you want your window to look like it belongs in a formal dining room, this velvet panel is the dramatic choice. The three-layer construction includes a solid shading layer that keeps the room dark even in strong sunlight, and reviewers point out it’s the answer they’d been looking for.
The blackout aspect leads the praise here, with close to 100 owners confirming it, followed by the luxurious appearance of the velvet. The heavyweight material blocks outside noise and helps hold heat in during winter, which is why it works so well for bedrooms and even as a room divider.
It comes with two hanging options — rod pocket and back tab — so you can choose the look that fits your rod. The honest note is sizing: most find it true to size, but some report it runs shorter than expected, so measure your drop carefully. The dark colors show a subtle silver plush reflection at certain angles, which most find gorgeous and some find unexpected.
Why It’s A Showstopper
- True 100% blackout from a three-layer velvet build
- Heavyweight fabric blocks noise and insulates
- Elegant look with two hanging methods
Before You Buy
- Check the length carefully — some run shorter than expected
- Velvet shows a silver reflection at certain light angles
Perfect for: anyone who wants blackout function wrapped in a truly luxurious, heavy fabric.
Be cautious if: your window needs an exact drop length — the sizing is the main mixed note.
8. jinchan Black Boho Floral Curtains
Interlocking vintage florals that turn your window into a piece of wall art.
This one is for the buyer who treats curtains as the centerpiece of the room. The two 50-inch by 84-inch panels feature a vintage floral print designed to connect smoothly when hung side by side, forming one continuous artwork — a trick no other panel in this list pulls off.
Appearance is the runaway top aspect here, with over 140 owners raving about how it livens up a room, and the light blocking is the strong second act. The densely woven backing cuts bright sunlight and softens noise, while the mid-century bohemian print brings color and warmth.
Buyers describe the fabric as soft, airy, and not stiff, with a drape that falls nicely thanks to the weight. The 1.6-inch grommets fit rods ranging from 0.63 to 1.5 inches, so it adapts to most existing hardware. Just note the panels are unlined, so the blackout here is “substantial” rather than the certified 100% of some competitors.
The Magic
- Interlocking vintage print makes one continuous artwork
- Dense weave blocks bright sunlight and softens noise
- Fits rods from 0.63 to 1.5 inches
The Reality
- Unlined construction is room-darkening, not 100% certified
- Pattern won’t suit minimal or modern-strict decor
Grab this if: you want a statement piece that doubles as functional window art.
Choose a solid panel instead if: your priority is absolute certified darkness over a vibrant print.
9. Beauoop Floral 100% Blackout Curtains
A grey leaf print over a triple-weave core that blocks 100% of exterior light.
This panel nails the “airy and subtle” look while hiding serious blackout power underneath. The graceful floral leaf pattern on a white background is the most-praised aspect — over 100 owners love how it adds a luxury, vintage feel that never dates — and the light blocking runs a close second.
The triple-weave double-layer fabric blocks 100% of exterior light while adding thermal insulation and noise reduction. Buyers confirm the black lining does heavy insulation work and keeps the heat out during summer, even in extreme heat.
At a substantial 4.8 pounds, the pair of 52-inch by 84-inch panels feels heavy and luxurious, not cheap. They wash wonderfully with no ironing needed, and one owner used them for an XL sliding glass door with great results. It’s a little heavier than the airy jinchan, so make sure your rod is solid.
The Highlights
- True 100% blackout with a heavy triple-weave build
- Subtle leaf print that adds vintage luxury
- Washes clean without needing an iron
The Trade-Off
- At 4.8 pounds, it needs a sturdy curtain rod
- Heavy drape is less “floaty” than lighter linen looks
Best for: large windows and sliding doors where you want full darkness with an elegant, subtle pattern.
Weigh this if: you’re mounting on a light decorative rod — the weight is real.
Understanding the Specs
Blackout Percentage
Manufacturers often state a range like 85%-99% or claim a flat 100%. Darker colors always block more light than light ones, so a black curtain will out-perform a cream one from the same line. If your room must be pitch black, look for the 100% claim or a lined backing — and be ready to accept small light leaks around the edges and seams.
Weave and Lining
The fabric construction is what does the work. Triple weave and dense backing are the two technologies you’ll see here, and both physically stop photons rather than just softening them. A lined curtain (like the KOUFALL) adds a separate light-blocking layer, while a triple weave builds the darkness directly into the fabric.
