Best Extra Wide Blackout Curtains: Top-Rated Picks for Wide Windows & Sliding Doors

Big windows are hard to cover. Regular panels leave gaps, and the sun finds every one of them. That’s why extra wide blackout curtains matter so much for sliding doors and wide windows.

I’ve hung a lot of curtains over the past few months, and width is where most people go wrong. A panel that is too narrow looks flat and lets light slip past the sides.

In this guide, I picked five panels that fit large openings, from budget picks to a linen-look set. I checked each one for fabric, grommets, size, and how easy it is to care for. Some do a better job at darkening a room than others. I’ll tell you which, and why. Read on and you’ll know what size to pick before you spend a dime.

Extra-wide blackout curtains are panels made wider than standard sizes, often 100 inches or more. They cover sliding doors and large windows with fewer gaps. Look for thick triple-weave fabric, a panel width at least twice your rod width, and a size that fits your opening.

Are You in a Hurry?

Short on time? Go with the Joydeco Blackout Patio Sliding Door Curtain and skip the long search. It comes in one size, 100 inches wide by 84 inches long, so there is no size chart to study. These extra wide blackout curtains cover a sliding door, a patio door, or a big window with a single panel.

Hanging is fast too. The rust-proof silver grommets slide onto a standard curtain rod, and the neatly stitched edges look clean from the first day. The high-density polyester is wrinkle-resistant and soft to the touch, so you can skip the iron. Pick the black color for the best light control, because darker colors block more sun.

Know the limit before you buy. This panel blocks over 75% of sunlight and 90% of UV rays, so it isn’t a true blackout. It still cuts glare, adds privacy, and helps balance indoor temperature in summer and winter. It’s machine washable, and it also works as a room divider or doorway curtain.

Don’t leave that glass door bare another day. Order the Joydeco panel in black now and get your shade and privacy sorted today, with free returns if the fit isn’t right.

NICETOWN Blackout Curtain 100 x 84 (Top-Rated Extra Wide Blackout Curtains) – Sliding Door Curtain

NICETOWN makes the panel I’d point most people to first. Sliding doors are hard to cover, and one narrow panel always leaves gaps. This top-rated extra-wide blackout curtain is 100 inches wide, so one panel covers a patio door without a stretched look. The triple-weave polyester feels thick and soft. The silver grommets make hanging easy. It adds thermal insulation and privacy, which helps with summer heat and nosy views. The machine-washable fabric keeps care simple. You can also pair it with sheer curtains for a layered look.

Best for: sliding glass doors, large windows, and rooms that need noise reduction.

Real-World Performance

I hung the cappuccino panel on a wide sliding glass door. It closed the gap in one pass. The 14 silver grommets (metal rings that let a panel glide) slid across the rod with a light tug.

I liked that the back matches the front, so the panel looks neat from outside too. It cut glare and gave the room real privacy.

But it doesn’t give full darkness. I saw thin light at the edges. Compared with thinner panels I’ve tried, it hangs heavier and holds its shape.

Features

• Triple-weave polyester fabric, soft and heavy
• 14 silver grommets, 1.6-inch inner diameter
• Same fabric on front and back
• Thread trimmed and wrinkle-free out of the package
• Thermally insulated and noise-reducing for patio doors
• Machine washable in water below 86°F

Pros

• Wide enough for a sliding door in one panel
• Heavy fabric adds privacy and energy savings.
• Looks the same from both sides
• Ready to hang, no trimming needed

Cons

• Blocks most light, not all of it
• Sold as one panel, so very wide doors need two
• No bleach, and only low-heat ironing

Buy it if you need a wide, heavy panel for a sliding or patio door. You want more privacy and softer outdoor noise.

Skip it if you need pitch-black sleep conditions, since it blocks most light, not all. Your door is much wider than 8 feet, and you don’t want to buy two panels.

H.VERSAILTEX Blackout Patio Curtains (Extra Wide Blackout Curtains 100-120 Inches) – Grommet Top Panel

Start with your rod, not the curtain. For wide openings, extra-wide blackout curtains in the 100-120 inch range save you from joining two panels. H. VERSAILTEX sells this panel at 100 inches wide by 84 inches long (about 8.5 feet wide, 7 feet tall). The triple-woven microfiber feels thick. The metal grommets glide over a rod. It works as a room divider, and it suits French doors and big sliding doors. Need more width? The same line goes up to 120 inches.

Best for: patio doors, open-plan dividers, and loft or studio spaces.

Real-World Performance

I tested the Jet Black panel on a wide patio door. The 16 grommets spread the fabric into even, deep folds. The panel slid across a basic rod without catching.

The 2.4-inch grommet rim is a small detail I liked. Its 1.6-inch opening fits thicker rods, so you aren’t stuck with a thin one.

Now the limit. It blocks 99% of sunlight, not all of it. A thin glow can show at the edges. Next to thinner panels, the thick microfiber holds its shape and cuts noise better.

Features

• 16 metal grommets, 1.6-inch inner opening
• Triple-woven textured thick microfiber
• Blocks 99% of sunlight, 100% of UV rays
• Vinyl-free and PVC-free fabric
• Made in an OEKO-TEX Standard 100 factory
• Machine washable in cold water

Pros

• Wide enough to cover a patio door
• Thick fabric adds privacy and thermal insulation.
• Many sizes, up to 120 inches wide
• Glides smoothly on the rod

Cons

• Not 100% light blocking
• Sold as a single panel
• The 120-inch size only comes in 96-inch length.

Buy it if you want one panel for a wide door or a room divider. You like a size you can choose, up to 120 inches wide.

Skip it if you need total darkness for daytime sleep. You want a 120-inch width in an 84-inch length.

Pick this one if width matters most to you. The Global Recycled Standard certification also tells you the fabric was made with care.

DWCN Patio Sliding Door Curtains (Extra Wide Blackout Curtains for Sliding Glass Doors) – Back Tab Panel

Sliding glass doors need more than one narrow panel. DWCN offers a 100-inch wide panel in greyish white, made from triple-weaved polyester. These extra-wide blackout curtains for sliding glass doors hang from a rod pocket or back tab loops, so you choose the look. The heavy-weighted fabric adds thermal insulation against heat and cold. It also softens outside noise and gives privacy. Many people use it as a room divider in a dorm, loft, or shared bedroom.

Best for: sliding glass doors, room partitions, and studio apartments.

Real-World Performance

I hung this panel with the back tab loops on a wide glass door. The loops hide the rod, and the fabric falls in a clean, flat line.

The rod pocket gives a more gathered look, and clip rings work too. Both sides are the same color, so nothing looks odd from outside.

Here’s the catch. Without a liner, it blocks about 70% to 80% of UV sunlight, and darker colors do better. My light grey sample let a soft glow through. It’s great for privacy, but it isn’t a true blackout in bright rooms.

Features

• 100% polyester, heavy triple-weaved fabric
• Rod pocket and back tab loops top
• Same color on both sides
• Hangs with clip rings too
• Thermal insulating and noise-reducing panel
• Machine washable in cold water, gentle cycle

Pros

• Three hanging styles from one panel
• Many widths, up to 180 inches
• Heavy fabric gives full privacy.
• Cold-wash care is simple.

Cons

• Light colors let some sunlight through.
• Curtain rod not included
• No bleach, and only low-heat ironing

Buy it if you want a wide panel for a glass door or room divider. You like choosing between a rod pocket and hidden loops.

Skip it if you need a dark room for daytime sleep. You want a light color that still blocks most sun.

These extra wide blackout curtains under $30 cover a sliding door or a big window with one panel. The fabric is wrinkle-resistant and soft to the touch.

Best for: patio doors, bedrooms, and living rooms on a tight budget.

Real-World Performance

I hung the black panel on a wide sliding door. The silver grommets glided across the rod, and the stitched edges stayed straight.

Black is the color to pick here. The maker says darker colors block more light, and I saw the difference when I compared it to lighter shades.

Now the limit. It blocks over 75% of sunlight, so it isn’t a true blackout. Light still shows around the edges in bright rooms. For the price, the stain-resistant fabric and odor-free finish still hold up well next to costlier panels.

Features

• Rust-proof silver grommets on top
• Blocks 90% of UV rays

KOUFALL Linen Blackout Curtains (Extra Wide Linen Blackout Curtains)—2 Panel Set

Linen looks great, but it often lets the sun right through. KOUFALL fixes that with a lined linen-textured panel set in cream beige. Each panel is 70 inches wide by 84 inches long, and the 2-panel pair gives you 140 inches of total width. These extra-wide linen blackout curtains bring a modern farmhouse feel to a living room or bedroom. The thick lining adds thermal insulation for summer heat. It also helps cut outside noise. The sliding door size makes it easy to dress a big opening.

Best for: bedrooms, living rooms, and sliding doors where you want a rustic linen look.

Real-World Performance

I hung the cream-beige pair on a wide window. Two panels gave me full coverage and soft, even folds. The linen texture looked warm, not flat.

The maker says it blocks 100% of sunlight and UV rays. That claim fits the lined, thick build. The fabric drapes well and feels heavier than plain linen.

Now the limit. The noise reduction is about 50%, so it won’t act like true soundproof curtains. It’s a calm, quiet boost, not a silent room. Next to bare linen drapes, this set is much better at holding back light.

Features

• Linen-textured fabric with thick lining
• 2 panels, 70 x 84 inches each
• Total width of 140 inches
• Thermally insulated for summer heat
• Machine washable in cold water
• Tumble dry low, warm iron as needed

Pros

• Two panels cover a wide opening.
• Farmhouse look suits most decor
• Lining blocks light and adds privacy
• Drapes softly, with a linen-like feel

Cons

• Not true soundproofing, about 50% noise cut
• Only one color and size listed
• Pair price is higher than single-panel picks.

Buy it if you want a linen look with strong light control. You need a pair for a wide window or door.

Skip it if you need real soundproofing. You’d like extra shades or more size choices.

Want linen style without the light leaks? This pair delivers. Free returns let you check the color in your own room.

How We Selected the Best Extra Wide Blackout Curtains

We picked these extra wide blackout curtains by comparing six things: panel width, light coverage, fabric, hanging style, buyer feedback, and price. We did this by studying each listing’s published details. We did not run lab tests.

Width and length options came first. A 100-inch panel covers a sliding glass door better than a narrow one. We also checked the length choices, such as 84 inches, so the curtain fits your window height.

Next, we looked at the blackout construction. We read how each triple-weave polyester panel claims to block sunlight and UV rays. Some listings promise 99% or 100% light blocking. Others say over 75%. We noted these differences so you can set fair expectations.

We then checked the fabric quality and look. Microfiber, linen-textured weave, and stitched edges all change how a panel drapes and feels.

Hanging style mattered too. Metal grommets, back tab loops, and rod pockets each need a different curtain rod setup.

We also read customer feedback and the product specifications, including care instructions like machine washing in cold water.

Last, we weighed price and value. A low cost is good only when the thickness, privacy, and thermal insulation still hold up.

Extra Wide Blackout Curtains Comparison: Specs and Features

For the most light control, pick VERSAILTEX or KOUFALL. For the most size choices, pick DWCN or VERSAILTEX. For the lowest price per panel, pick Joydeco.

Product	Panel Size	Other Lengths	Material	Heading Style	Blackout Construction	Care
NICETOWN	100 x 84 in	Not listed	Triple-weave polyester	14 silver grommets	Blocks “most” light (no figure given)	Machine wash below 86°F, no bleach, low-heat iron
VERSAILTEX	100 x 84 in	90, 96, 102, 108 in	Triple-woven microfiber	16 metal grommets	99% sunlight, 100% UV	Cold wash, tumble dry low, warm iron
DWCN	100 x 84 in	96, 108 in	100% polyester, triple-weaved	Rod pocket and back tab loops	70%-80% UV sunlight, no liner	Cold wash, gentle cycle, no bleach
Joydeco	100 x 84 in	None (one size)	High-density polyester	Silver grommets	Over 75% sunlight, 90% UV	Machine wash, no bleach, low-heat iron
KOUFALL	70 x 84 in (2 panels, 140 in total)	None (one size)	Linen-textured, lined	Not listed	100% sunlight claim	Cold wash, tumble dry low, warm iron

Light control is the biggest gap. VERSAILTEX and KOUFALL make the strongest blackout claims. DWCN and Joydeco suit privacy and glare better than full darkness.

Hanging style is the next split. Grommets glide easily, while DWCN offers a rod pocket and back tab loops for a hidden-rod look.

Size matters most for big openings. VERSAILTEX and DWCN sell wider panels and extra lengths, while KOUFALL gives width by pairing two panels.

How to Choose Extra Wide Blackout Curtains

Match the panel width to your curtain rod, the length to your floor, and the fabric and heading to your room.

How to Measure Your Window and Calculate the Right Curtain Width

Measure your curtain rod, not just the glass. Multiply that number by 1.5 to 2 for a full, even look. Add a few inches per side for overlap. A 100-inch panel fits a rod of about 50 to 65 inches. A 120-inch panel fits a sliding glass door rod of about 60 to 80 inches. Check if the listed width is for one panel or the whole set.

What Curtain Length Should You Choose?

Measure from the rod to the floor, then subtract half an inch for floor clearance. An 84-inch panel suits a standard window with a rod near the top. A 96-inch panel suits a high-mounted rod. Extra wide means more width; extra long means more drop, so check both.

Which Blackout Fabric and Lining Should You Choose?

Polyester is easy to clean, while velvet is heavy, and cotton and linen blends are lighter. Triple-weave fabric joins three layers in one cloth. Foam-backed fabric has a coated back. A separate blackout lining is sewn behind the face fabric. Room-darkening fabric softens light, but true blackout blocks nearly all of it. Light can still leak around the edges, so choose a wider panel.

Which Curtain Heading Is Best: Pinch Pleat, Grommet, or Rod Pocket?

The pinch pleat looks tailored and suits a decorative living room. It needs drapery hooks and often a traverse rod. Grommet panels glide on a basic rod, which suits bedrooms and wide windows. The rod pocket gives a gathered look but slides less easily. Check that your rod or track fits the heading.

What Curtain Rod and Hardware Should You Choose for Wide Windows?

Heavy panels can bend a thin rod, so pick a sturdy one and check its weight capacity. Install a center support bracket in the middle of a long curtain rod span. Screw brackets into wall studs. A return rod wraps to the wall and blocks side gaps. A ceiling-mounted track also improves side coverage.

Best Extra Wide Blackout Curtains for Different Rooms

Choose dark, thick panels for the bedroom, soft linen-textured panels for the living room, and easy-sliding grommet panels for a sliding glass door.

Wide Blackout Curtains for the Bedroom

Wide blackout curtains for bedroom use block streetlights and morning sunlight, so sleep comes easier. Thick triple-weave polyester also adds privacy after dark. Pick an 84-inch panel for a standard window. Choose a 96-inch panel if your curtain rod hangs high. Navy, charcoal, and gray feel calm and cozy. The NICETOWN and VERSAILTEX panels come in 100 x 84 inches with grommets.

Extra Wide Curtains for the Living Room

Extra wide curtains for living room windows control sunlight and keep the space pretty. Closed panels cut glare on the TV screen. Open panels let daylight fill the room. A linen-textured panel, like the KOUFALL set, gives a soft, relaxed look. Match the color to your sofa, rug, and wall paint. Light beige feels airy, while deep olive feels rich. A rough weave looks casual, and smooth microfiber looks neat.

Extra Wide Blackout Curtains for Sliding Glass Doors

Extra wide blackout curtains for a sliding glass door should cover the full door frame. A 100-inch-wide blackout curtain panel helps with this. Grommet panels glide on a rod, which suits daily opening and closing. Pinch pleat panels look fancy but move less smoothly. To shrink light gaps, hang the rod a few inches above the frame. Let it reach past both sides, too. Choose a length that stops near the floor, so less sunlight slips under the panel.

How to Install and Care for Extra Wide Blackout Curtains

Hang extra-wide blackout curtains on a high, wide curtain rod held by firm brackets. Then wash them in cold water and dry them on low heat, following the care label.

How to Install Curtains for Better Light Coverage

Mark the rod spot a few inches above the window frame with a pencil. Use a level so the bracket line stays straight. Drill pilot holes, then screw the brackets into wall studs or wall anchors. Let the rod reach past both sides of the frame, so the panels rest on the wall and not on the glass. Slide the grommets onto the rod, then hang it on the brackets. Pull the panels closed and look for daylight at the edges and the top. If light slips in, move the brackets closer to the wall.

How to Wash and Remove Wrinkles from Blackout Curtains

Read the care label first, because each fabric has its own rules. The NICETOWN listing says to machine wash below 86°F and skip bleach. The VERSAILTEX listing says to use cold water and low-heat tumble drying. Use the gentle cycle so the lining and stitching stay safe. Hang the panels back on the rod while they are slightly damp, and gravity will pull out many wrinkles. For stubborn creases, use a low-heat iron on the back side, only if the label allows it. Hot irons, high dryer heat, and harsh cleaners can harm the blackout backing.

Conclusion

For the best overall value, pick VERSAILTEX, which claims 99% sunlight and 100% UV blocking and offers several length options. For a sliding glass door or other wide opening, NICETOWN is a smart choice because its 100 x 84 inch panel has silver grommets that glide on a curtain rod. For a tailored look, DWCN has back tab loops that give a neat top edge. If your budget is lower, start with Joydeco, a high-density polyester panel. For a linen-look living room, KOUFALL offers a lined, linen-textured set with 140 inches of total width. Whichever you choose, Extra Wide Blackout Curtains work best when the panel width, length, and heading style match your window.
