How To Choose The Best 120-Inch Blackout Curtains
Buying extra-long curtains requires checking fabric weight, hanging style, and width coverage. You are covering a tall space — a sliding door, a floor-to-ceiling window, a patio entrance — so every spec matters more. Here is what separates a curtain that merely hangs from one that delivers true blackout.
Light Blocking: The Real Numbers Behind “Blackout”
Before you buy, know that “blackout” labels vary widely. Some panels block 100% of light with a heavy double-layer build, while others only cut 80% to 85% — that’s really “room darkening,” not full blackout. Check the fabric weight: a 230GSM (grams per square meter) layer per side with a built-in black lining performs far better than a single thin sheet. If you’re a shift worker or setting up a baby’s nursery, you need that 100% claim backed by thick, multi-layer fabric, not just a label.
Fabric, Feel, and Your Room’s Vibe
The material dictates both the look and the light-blocking performance. Polyester gives you durability and easy care, velvet adds luxury and a heavier drape, and linen offers a textured, natural aesthetic. Consider what your room needs: velvet blocks light and muffles sound but can feel heavy, while linen is breathable but may need a separate blackout lining to truly deliver darkness. Your choice here shapes both darkness and the room’s overall aesthetic.
Hanging Style and Installation Reality
Before you fall in love with a fabric, check how it hangs. Grommet tops slide easily on standard rods and are the most common, but the ring size matters — a 1.6-inch inner diameter fits most rods, while a smaller ring can limit your coverage. Rod pockets give a soft, gathered look but can be trickier to slide. Back tabs offer a clean, tailored appearance and work well on tracks. Match the hanging style to your rod’s diameter and track type.

In‑Depth Reviews
1. NICETOWN Extra Long Truly Blackout Drapes
Our pick — over 4.5★ from 79,000+ verified ratings; the strongest balance of quality and price.
The shift-worker’s savior that turns noon into midnight.
This is the panel that delivers on the hardest promise in this category: total darkness. The 100% physical blackout comes from a heavy double-layer build — two layers of high-density 230GSM woven polyester with a built-in black lining that shuts out all incoming light. That is not marketing math; that is 460GSM total weight hanging on your rod, which is why buyers in desert climates report it keeps rooms cooler when the heat is breaking records.
The quality is the thing everyone raves about, and the numbers back it up — quality is the most-discussed aspect by far, with thousands of owners singling it out. The fabric has a smooth, luxurious texture that drapes elegantly, and the bright white color (with a black lining on the back) is a favorite. It hangs on silver-colored grommets with a 1.6-inch inner diameter, which slide easily across most standard rods, so setup takes minutes rather than an afternoon.
One honest caveat: a few owners found the grommet rings too small for their specific pole, which can limit how wide you can draw the panels. This is a fit consideration, not a flaw. — the 52-inch width per panel (104 inches total for the set) covers most standard windows, and you can size up for wider spaces. Hand wash or dry clean only; skip the machine to protect the double-layer weave.
What Wins You Over
- 100% physical blackout that genuinely blocks all light
- Heavy 230GSM double-layer fabric feels premium and insulates
- Easy slide on standard rods with 1.6-inch grommets
What to Check First
- Hand wash or dry clean only — no machine washing
- Some poles may need larger rings for full draw
Grab it for: night-shift workers, nurseries, or anyone who needs true cave-dark sleep.
Think twice if: you prefer machine-wash convenience over maximum light blocking.
2. Simplebrand Silver Grey Extra Long 10ft Curtains
A budget-friendly panel that punches well above its weight.
Need extra-long panels without the premium price? This set delivers. Its three-layer weave uses a middle layer of black yarn to block 85% to 60% of light — darker colors hit the 85% mark, while white still cuts 60% — so it’s a solid “room darkening” performer, though not total blackout. The identical silver grey on both sides keeps it looking sharp from every angle.
What wins buyers over here is color accuracy and value. Buyers report the silver grey matches the product pictures exactly, and the smooth, easy-to-handle fabric earns steady praise. At 3.6 pounds for the package, it’s light enough for one person to install solo — as one buyer put it, “they were not too heavy for me to handle installation by myself. Yet, blocked the glare from the morning sun.” That mix of easy handling and real glare reduction suits patio doors and tall living room windows.
The honest trade-off is thickness — some owners find the fabric a bit thin, and because it is not a 100% blackout panel, you may see daylight around the edges on bright afternoons. This is a fit question, not a defect: if you want total darkness, step up to a 100% panel; if you want effective dimming with an easy budget entry, this is your pick.
Smart budget move: the room-darkening results are the most-praised feature here, and the anti-rust silver grommets slide smoothly for easy hanging.
Reality check: for a true 100% blackout effect, you will want to size up to a heavier double-layer panel — this one dims beautifully but does not fully block.
3. Hiasan Velvet Blackout Curtains 120 inch
Velvet luxury that does not demand a designer budget.
This lavender set proves you can get high-end looks without the high-end price. The thick velvet fabric blocks 80% of light — solid room darkening for bedrooms and living spaces — while adding a plush, elegant texture that owners describe as luxurious to the touch. The 5-pound weight per set gives it a pendulous, heavyweight drape that hangs beautifully, and the built-in tiebacks of the same color and material are a thoughtful addition.
Quality is the most-mentioned aspect here, and it shows in the details. The velvet is silky smooth and soft while still feeling substantial, and the color options hold up well — owners note the color does not fade even in direct sunlight. The dual rod pockets (3 inches and 1.5 inches) let you hang it two different ways, and it also works with clip rings, so you have flexibility in how you style it.
A fair warning: at 80% light blocking, this is room darkening rather than total blackout, and the velvet is medium-weight rather than heavy-duty. Owners say it darkens a room “well enough” for sleeping in on weekends but is not the choice for shift workers needing cave-dark conditions. It also keeps rooms cozy in winter, even without a typical insulation layer.
Style-first pick: the soft velvet texture and color stability in sunlight make this a decor upgrade as much as a light blocker.
Not for purists: 80% blocking means it dims beautifully but cannot deliver total darkness.
4. KEQIAOSUOCAI Cocoa Brown 100% Blackout Linen Curtains
Linen texture with a 100-percent blackout secret inside.
Here is the pick that gives you the organic, textured linen look without sacrificing total darkness. The rich linen fabric is layered with a completely blackout interlayer that blocks 100% of sunlight and UV rays, so you get the aesthetic of a shabby-chic farmhouse with the function of a serious blackout panel. The cocoa brown color runs the same front and back, so it looks finished from every angle.
The 8 silver rings per panel (1.11-inch inner diameter) make it easy to install and slide, and the 50-inch width per panel (100 inches total) covers sliding glass doors and wide windows well. Owners consistently praise the quality and the true color — owners mention it arrives without a greyish tone and looks “very expensive” on the rod. The fabric is thick and sturdy without being heavy or bulky, and the waterproof coating on both sides means it can handle indoor and outdoor use.
The recurring complaint is wrinkles: panels can arrive creased and rough-looking straight from the package, needing a good steam or press before they hang beautifully. This is a care step rather than a flaw, and the machine-washable, vinyl-free fabric makes it easy to refresh. For a door that needs both style and serious light blocking, this is a strong, balanced choice.
Why It Stands Out
- 100% blackout interlayer with a natural linen face
- Machine washable and vinyl-free for easy upkeep
- Waterproof coating suits both indoor and patio use
Plan For This
- Expect to steam out packaging wrinkles before hanging
- Wider windows may need extra panels for full coverage
5. RYB HOME Black Velvet Blackout Curtains 120 inches
The plush velvet drape that makes a room feel five-star.
This velvet feels plush, heavy, and silky, with a drape owners call luxurious and gorgeous. Its 75% to 85% blackout rating makes it a strong room darkener, not a total blackout panel, but the dense fabric blocks most sunlight and UV rays, creating a cozy, dark space for a daytime rest. At 52 inches per panel (104 inches total), it generously covers standard windows.
Quality and appearance are the twin stars here — both are among the most-praised aspects, and it shows in the 8 rustproof grommets (1.6-inch inner) that slide smoothly on standard rods. The color options are a highlight, with owners loving the true-to-photo shades and noting the fabric’s weight keeps it hanging in place. It is thick enough to also muffle noise and block drafts, adding an energy-saving layer to its beauty.
One note for velvet lovers: because it is not a 100% blackout panel, some light edges in around the sides on the brightest days. A few owners also mention light wrinkles from packaging, but these release once the curtains hang. Machine wash on gentle or dry clean, and steam the backside to refresh the fold.
Luxury with function: the plush, silky velvet and true colors deliver a high-end look that owners say is “well above what they cost.”
Dim, not black: 75% to 85% blocking means it excels at darkening but is not the pick for total light elimination.
6. Guken Olive Green 100% Blackout Linen Curtains
Cave-dark linen that keeps summer heat on the other side of the glass.
If your room turns into a greenhouse by mid-afternoon, this is the curtain engineered to fight back. The gray backing on this linen blend delivers a 100% blackout effect — owners describe the result as “cave-like darkness” — while the fabric’s thermal insulation keeps rooms cooler in summer and cozier in winter. It is a functional powerhouse dressed in an elegant olive green that looks rich and true to the photos.
The back tab hanging style gives a clean, tailored look, and the set includes 30 pleat hooks, so you can switch to a sleek, luxurious drape with easy sliding if you prefer. The linen texture earns praise for its elegance, though a few owners find it a bit stiff — a texture preference rather than a defect. The fabric is substantial and soft, with no plastic coating, which is a relief for anyone sensitive to chemical smells in window treatments.
At 52 inches wide per panel (104 inches total), it covers wide windows and sliding doors well, and the machine-washable care makes it easy to maintain. Owners note it hangs cleanly with minimal wrinkles and supports rods well. For a combination of total darkness and real thermal performance, this is a standout.
Functional Star
- 100% blackout with a gray backing that fully blocks sun and UV
- Thermal insulation keeps rooms cooler in summer and warmer in winter
- Versatile back tab and hook hanging options included
Feel It First
- Linen texture is beautiful but a few owners find it stiff
- No rings or clips included — only pleat hooks
7. Topfinel Extra Long Dark Brown Velvet Curtains
The boho statement piece that feels like a hotel suite.
Here is the curtain that does double duty as a decor centerpiece. The 300 GSM high-density velvet is pure indulgence — plush, soft, and heavy enough to hang with a luxurious, opulent drape that owners say looks like it belongs in a five-star hotel. The dense pile blocks 85% of sunlight and UV rays, cutting glare and helping maintain comfortable room temperatures while adding a sophisticated focal point to any space.
Quality and appearance dominate the praise here — owners describe the velvet as lush with beautiful stitching, and the color options are true to the photos (the olive green is a favorite, even if slightly darker than pictured). The multiple hanging options are a standout: rod pockets, back tabs, or track systems, so you can adapt it to whatever hardware you already own. The 120-inch length covers floor-to-ceiling windows grandly.
The honest catch is the light blocking: at 85%, it is room darkening rather than total blackout. Owners note it blocks moonlight and streetlights fully at night, but on sunny days some light filters through the lighter shades in a gold or orange glow. If you need absolute darkness, this is not the panel; if you want a dramatic, luxurious look with strong dimming, it delivers beautifully.
Decor-first pick: the hotel-quality velvet and true colors make this a room transformation, not just a window covering.
Darkening, not blackout: expect strong dimming and night-time privacy, with some sunlight through lighter shades by day.
8. MIULEE Natural Pinch Pleated 100% Blackout Linen Curtains
The custom-tailored look without the custom-tailor price.
This is the pick for anyone who wants that high-end, professionally draped appearance. The dual-layer construction pairs a soft high-density linen outer with a thick white blackout lining that blocks 100% of sunlight and UV rays, giving you total darkness with an organic, natural warmth. Seven permanent pinch pleats per panel create a refined, three-dimensional look, and the 1.6 times fabric width adds a generous, elegant fullness that feels custom-made.
Appearance is the standout aspect here, and it shows in the details. Each panel is meticulously shaped with 248°F (120°C) steam for 60 minutes to maintain its form and resist wrinkles, and two 12g weighted corners ensure a gallery-straight hang. The set comes complete with 20 hooks, 20 clips, and 20 metal rings — everything you need for four different hanging methods (hook pleat, ring clip, track, or hidden rod pocket), so there are no compatibility surprises.
Owners consistently describe these as beautiful and expensive-looking, with excellent light blocking and a heavy, durable feel. The natural linen-blend (30% linen, 70% polyester) balances linen’s breathability with polyester’s wrinkle resistance. The trade-offs: the fabric can feel a bit rough or scratchy to some, and the panels may need light steaming to remove packaging creases. At 40 inches wide, you will likely need two sets for wider windows.
The Tailored Advantage
- Seven permanent pinch pleats create a luxurious, custom drape
- 100% blackout lining with a natural linen face
- All hooks, clips, and rings included — four hanging methods
Before You Buy
- 40-inch width is narrow — budget for two sets on wide windows
- Some owners find the linen texture on the rougher side
Understanding the Specs
GSM and Fabric Weight
GSM stands for grams per square meter — the higher the number, the denser and heavier the fabric. A 230GSM layer per side with a total of 460GSM is the difference between a flimsy sheet and a curtain with real presence. Heavier fabric blocks more light, insulates better, and hangs with a more luxurious drape, but it also weighs more on your rod and takes more effort to install.
Blackout vs. Room Darkening
These are not the same thing. A 100% blackout panel uses a dense multi-layer build or a blackout lining to block all light. Room darkening curtains typically block 75% to 85% of light — enough for privacy and dimming, but with light leaking around the edges on bright days. Check the claim before you buy: if you work nights or have a nursery, you want the 100% figure, not the 80% one.
Thermal Insulation
Thermal insulation means the fabric creates a physical barrier that slows heat transfer through the window. In practical terms, this keeps rooms cooler in summer and warmer in winter, which can cut energy costs. Heavy, multi-layer fabrics do this best — a single thin panel will not give you the same temperature-regulating effect as a 460GSM double-layer construction.
Hanging Styles Explained
Your rod dictates which hanging style works. Grommet tops have metal rings built in — they slide easily and are the most simple to use. Rod pockets are fabric sleeves that create a soft, gathered look but can drag. Back tabs give a clean, tailored appearance and work on tracks or rods. Pinch pleats offer the most formal, custom look with multiple hooks and rings. Match the style to your existing hardware.
