The best blackout blinds balance light control with a fit and installation style that suit your window. My best overall pick is the AOSKY Cordless Blackout Roller Shade in 34 × 72 inches, a straightforward choice for standard windows; the Persilux custom-size roller shades stand out for tailored sizing, while the LazBlinds no-drill cellular shades suit renters and smaller windows. The main tradeoffs are between a close, custom fit and easy setup, and between compact roller designs and bulkier cellular construction. Portable cut-to-size shades offer flexibility, but they may not look as finished as mounted blinds. Read on for the full breakdown and advice on matching a shade to your room and window.

Key Takeaways
- The lineup’s strongest distinction is fit: standard-size rollers suit common windows, while the two Persilux custom-size options address openings that fixed dimensions may not cover well.
- For renters or anyone avoiding holes in the frame, the two LazBlinds no-drill cellular shades fill a different role from the mounted roller shades, though their listed sizes limit where they fit.
- The portable Petaholic and RUseeN shades use large cut-to-size panels rather than a finished, fitted blind; that flexibility can help with unusual windows, but measuring and trimming become part of the job.
- Cellular styles appear in both compact and larger formats, giving buyers more construction choices; a cellular design is not automatically a better fit than a simple roller shade.
- Several shades share similar widths and lengths but vary in valance, color, and installation approach, so buyers should match exact dimensions and mounting needs before choosing by appearance.

More Details on Our Top Picks
TWODRAPES Cordless Blackout Roller Shade with Valance, Beige Oatmeal, 34 x 72 in
The TWODRAPES stands out for buyers who want blackout coverage without an exposed roller mechanism. Its matching fabric valance and wrapped bottom rail give the window a more finished appearance than the simpler LazBlinds Blackout Cordless Roller Shade, which is better suited to shoppers prioritizing trim-to-fit flexibility and adhesive installation. The free-stop cordless control lets you set the shade at different heights without loose cords, while the linen-polyester fabric adds a softer look than plain black roller shades. It can mount inside or outside the frame, giving it more placement flexibility than the inside-only AOSKY cellular shade. The tradeoffs are practical: the shade fabric is narrower than its valance, which may leave side gaps, and spot-clean-only care limits cleanup options.
Pros:- Cordless free-stop operation avoids dangling cords and allows variable positioning.
- Blackout fabric offers room darkening, privacy, and UV protection.
- Inside- or outside-mount installation suits different window frames.
- Matching valance and wrapped bottom rail create a coordinated appearance.
Cons:- The fabric is 0.6 inches narrower than the valance, which can leave light gaps at the sides.
- Spot-clean-only care is less convenient for stains or heavy dust.
Best for: Buyers seeking a neutral, coordinated blackout roller shade with cordless operation and a choice of inside or outside mounting.
Not ideal for: Shoppers who need a close edge-to-edge fit for maximum light blocking or want a shade they can wash rather than spot clean.
- Dimensions:34 in W x 72 in H
- Color:Beige Oatmeal
- Material:Linen and polyester
- Opacity:Blackout
- Operation:Manual, cordless free-stop
- Mounting:Inside or outside mount
- Care:Spot clean only
- Included items:Metal brackets, magnets, screws, installation guide
Our verdict“Choose the TWODRAPES if a finished, neutral look and flexible mounting matter more than exact edge coverage or easy washing.”
Petaholic Portable Blackout Curtain, DIY Cut-to-Size, 118 x 57 in
The Petaholic portable curtain is the most adaptable choice here when a standard roller shade will not suit the window or when blackout coverage needs to travel. Its large polyester panel can be cut to fit different shapes, then attached with adhesive stickers and Velcro, avoiding the fixed-width commitment of the TWODRAPES roller shade. A silver-coated backing is designed to block sunlight and UV rays, and the included storage bag makes it easier to pack away between trips or temporary stays. That flexibility comes with a less polished setup: the mounting depends on a clean, dry surface, and adhesive attachment is not the same as a permanent, neatly framed blind. The fabric may also have an odor when opened, and dry-clean-only care makes regular maintenance less convenient than spot-cleanable roller shades.
Pros:- Large panel can be cut to fit varied window sizes and shapes.
- Portable, foldable design includes a storage bag.
- Adhesive stickers and Velcro allow installation without drilling.
- Silver-coated backing is designed to block sunlight and UV rays.
Cons:- Adhesive installation needs a clean, dry window surface to hold properly.
- Dry-clean-only care is less convenient than spot-cleanable roller shades.
- The fabric may have an odor when first opened.
Best for: Renters, travelers, and families who need adjustable blackout coverage for irregular windows or temporary sleeping spaces.
Not ideal for: Buyers seeking a permanent, finished window treatment or an option that can be machine-washed or easily wiped clean.
- Dimensions:118 x 57 in
- Weight:1.2 lb
- Material:100% polyester, Oxford weave
- Color:Black
- Opacity:Blackout
- Installation:Nano-adhesive stickers and Velcro
- Care:Dry clean only
- Included components:Curtain, 18 adhesive stickers, 12 pairs of Velcro, storage bag, instruction manual
- Warranty:1 year
Our verdict“Pick the Petaholic for portable, customizable coverage, but choose a roller shade like the SUNOFF for a more permanent and finished installation.”
LazBlinds Blackout Cordless Roller Shade, 36 x 72 in, Black
The LazBlinds roller shade earns its place for buyers who want a fixed blackout shade that can be trimmed to width and installed without drilling. That combination makes it more adaptable to a particular window than the SUNOFF Cordless Blackout Roller Shade, which offers inside or outside mounting but is not described as trim-to-fit. Adhesive fasteners and included clips also suit clean, flat surfaces where drilling is unwelcome. Its cordless design keeps the window clear of hanging cords, while the black polyester backing supports privacy and light control. The compromise is a simpler treatment: it lacks the concealed valance of SUNOFF and the coordinated fabric finish of TWODRAPES. It is also not water resistant and requires spot cleaning, so it is a poor match for damp rooms or windows that need frequent washing.
Pros:- Trim-to-fit width helps adapt the shade to a specific window.
- No-drill adhesive installation uses included clips and fasteners.
- Cordless operation avoids dangling cords.
- Blackout backing supports privacy and UV protection.
Cons:- Not water resistant, limiting suitability for damp spaces.
- Spot-clean-only care can make marks harder to remove.
- No valance is listed, so the roller mechanism is less concealed than on the SUNOFF.
Best for: Renters and DIY installers who need a cordless blackout shade that can be trimmed to width and attached without drilling.
Not ideal for: Buyers who need a decorative valance, water-resistant window covering, or washable fabric for a high-moisture or messy room.
- Size:36 in W x 72 in H
- Color:Black
- Material:Polyester
- Opacity:Blackout
- Operation:Manual, cordless
- Mounting:Inside or outside mount; no-drill adhesive installation
- Water resistance:Not water resistant
- Care:Spot clean only
- Included components:2 clips, 2 tubes, 1 connector
Our verdict“Choose LazBlinds when trimming the width and avoiding drilled holes matter more than a concealed roller or moisture resistance.”
SUNOFF Cordless Blackout Roller Shade, 34 x 72 in, Black
The SUNOFF is a strong choice for buyers who want a straightforward roller shade with a tidier finish and useful temperature-control features. Its valance hides the roller mechanism, unlike the more utilitarian LazBlinds trim-to-fit shade, while blackout polyester is designed to block light and UV rays and help insulate against heat. The cordless free-stop system lets you adjust coverage to different heights without managing a cord. Inside- or outside-mount support gives it more installation flexibility than the AOSKY cellular shade, which is limited to inside mounting and needs a minimum frame depth. SUNOFF is not described as trim-to-fit, however, so buyers should confirm the listed width suits their window. It also is not water resistant and is spot-clean only, making it less suited to damp rooms or frequent spills.
Pros:- Blackout polyester includes UV protection and thermal insulation features.
- Cordless free-stop control adjusts to different heights.
- Valance conceals the roller mechanism for a tidier window appearance.
- Supports inside or outside mounting.
Cons:- Not water resistant, so it is a poor fit for damp locations.
- Spot-clean-only care limits cleanup options.
- No trim-to-fit feature is listed, so the fixed width may not suit every window.
Best for: Buyers who want a black, cordless roller shade with a concealed mechanism, adjustable height, and inside- or outside-mount flexibility.
Not ideal for: Shoppers who need a custom-trimmed width, a water-resistant shade, or a window covering suited to frequent washing.
- Dimensions:34 in W x 72 in H
- Color:Black
- Material:Polyester
- Opacity:Blackout
- Operation:Manual, cordless free-stop
- Mounting:Inside or outside mount
- Water resistance:Not water resistant
- Care:Spot clean only
- Included components:Mounting hardware, user manual, screws, handle
Our verdict“Choose SUNOFF for a concealed, adjustable roller shade with flexible mounting, provided its fixed width fits your window.”
AOSKY Cordless Blackout Cellular Shade, 34 x 48 in, White
The AOSKY cellular shade is the standout for buyers who value insulation and tool-free installation over broad mounting flexibility. Its aluminum-coated honeycomb construction is designed to block light and UV rays, help insulate against heat and cold, and reduce outside noise—benefits a basic roller shade such as the SUNOFF does not specifically claim for noise reduction. The tension mount also avoids drilling, and the cordless free-stop rail makes height adjustment simple. The limitations are more restrictive than those of the TWODRAPES or SUNOFF: this model is intended for inside mounting only, needs at least 1.2 inches of frame depth, and measures just 48 inches tall. That shorter length suits some windows but rules it out for taller openings. I would choose it for a compatible frame, not as a flexible, all-window solution.
Pros:- No-drill tension mounting requires no tools.
- Honeycomb construction is designed to insulate against heat and cold.
- Blackout design blocks sunlight and UV rays.
- Cordless free-stop rail allows adjustable positioning.
Cons:- Requires at least 1.2 inches of frame depth.
- Designed for inside mounting only.
- The 48-inch height is shorter than the 72-inch roller shades in this lineup.
Best for: Homeowners with at least 1.2 inches of window-frame depth who want tool-free blackout coverage with added insulation and noise reduction.
Not ideal for: Buyers with shallow frames, windows requiring outside mounting, or taller openings that need more than 48 inches of shade length.
- Size:34 in W x 48 in H
- Color:White
- Opacity:Blackout
- Material:Aluminum and polyester
- Operation:Manual, cordless
- Mounting:Inside mount, tension mount
- Minimum frame depth:1.2 in
- Weight:1.35 kg
- Included items:Shade, bottom rail handle, installation instructions, wrench
Our verdict“Choose AOSKY if your frame meets the depth requirement and insulation matters more than outside mounting or longer coverage.”
MYshade Blackout Cordless Roller Shade, 24 x 72 in, Black
For a narrow window that needs a simple blackout treatment, the 24-inch MYshade keeps the setup straightforward: its polyester fabric is designed to block light, while the cordless free-stop control lets you set the height without dangling cords. Compared with the wider AOSKY Cordless Blackout Roller Shade, this is a better fit for smaller openings, but it covers less window width and is less adaptable if you want to mount outside the frame. Inside mounting can leave light gaps at the sides, so buyers seeking a darker room may need to measure carefully or choose an outside mount if their setup allows it. It is a practical, single-window option, though spot-clean-only care limits cleanup choices.
Pros:- Blackout polyester is intended to reduce sunlight and improve privacy.
- Cordless operation avoids dangling cords.
- Free-stop control allows flexible positioning.
- Installation accessories and a user manual are included.
Cons:- Inside mounting may leave side gaps that let light through.
- Spot-clean-only care limits cleaning options.
- The 24-inch width is suited to narrower windows, not broad openings.
Best for: Buyers with a narrow indoor window who want a cordless blackout shade with adjustable positioning.
Not ideal for: People covering wide windows or seeking a close-to-edge blackout fit from an inside mount, since side gaps may admit light.
- Dimensions:24 x 72 in
- Color:Black
- Material:Polyester
- Opacity:Blackout
- Operation:Manual, cordless free-stop
- Mounting:Inside mount
- Care:Spot clean only
- Included:Shade, installation accessories, user manual
Our verdict“Choose MYshade for a narrow window and simple cordless control, but not for wide coverage or minimal side light.”
Joydeco Cordless Blackout Cellular Shade, 35″ W x 64″ H, White
The Joydeco cellular shade is the pick here for buyers who want more than a darkened window. Its honeycomb construction and aluminum foil lining are designed to support thermal insulation as well as block up to 99% of light, which may suit bedrooms or workspaces exposed to sun. Unlike the simpler MYshade roller shade, Joydeco adds a cellular structure and offers inside or outside mounting; that flexibility can help when a frame fit is awkward. The tradeoff is that its 35-by-64-inch size may not suit taller windows, and inside mounting calls for accurate measurements. It is also not water resistant and is spot-clean only, so I would skip it for damp rooms or windows prone to splashes.
Pros:- Designed to block up to 99% of light.
- Honeycomb construction and foil lining support thermal insulation.
- Cordless control stops at adjustable heights.
- Can be mounted inside or outside the window frame.
Cons:- The 64-inch height may not cover taller windows.
- Not water resistant, limiting use in damp or splash-prone spaces.
- Inside mounting requires accurate window measurements.
Best for: Buyers fitting a medium-width window who want blackout performance alongside UV filtering and added insulation.
Not ideal for: People covering taller windows, installing in a damp area, or unable to measure an inside mount accurately.
- Dimensions:35 in W x 64 in H
- Color:White
- Material:Polyester
- Lining:Aluminum foil
- Light blocking:Up to 99%
- Operation:Manual, cordless
- Mounting:Inside or outside mount
- Care:Spot clean only
- Weight:1.36 kg
Our verdict“Pick Joydeco when insulation and light control matter more than a taller drop or easy tolerance for measurement errors.”
AOSKY Cordless Blackout Roller Shade, 34″ W x 72″ H, Black
For an office window where glare and sun exposure are the main nuisances, this AOSKY roller shade combines blackout fabric with thermal insulation and UV protection. Its 34-by-72-inch size is broader than the MYshade, making it a more useful fit for many standard-width windows, while the cordless free-stop mechanism gives control over how much daylight to admit. A built-in valance and aluminum alloy rods add structure, and inside or outside mounting gives more installation choice than MYshade’s listed inside-mount setup. Compared with the cellular Joydeco, AOSKY has a simpler roller format rather than honeycomb construction. It is not water resistant, and spot-clean-only care makes it a poor choice for messy or damp spaces.
Pros:- Blackout fabric is paired with thermal insulation and UV protection.
- Cordless free-stop operation allows quiet, adjustable positioning.
- Inside and outside mounting are supported.
- Built-in valance and aluminum alloy rods add structure.
Cons:- Not water resistant.
- Spot-clean-only care may be limiting in high-use spaces.
- The roller design lacks the cellular construction offered by Joydeco.
Best for: Home-office users with a medium-width window who want adjustable blackout coverage and UV protection.
Not ideal for: Buyers outfitting damp rooms or needing a shade that can be washed rather than spot-cleaned.
- Dimensions:34 in W x 72 in H
- Color:Black
- Opacity:Blackout
- Operation:Manual, cordless free-stop
- Mounting:Inside or outside mount
- Material:Aluminum and polyester
- Features:Thermal insulation, UV protection, built-in valance
- Care:Spot clean only
- Weight:1.36 kg
Our verdict“Choose AOSKY for an office window needing broad, adjustable blackout coverage with UV protection, not for damp rooms.”
Persilux Cordless Blackout Roller Blind with Valance, White, 47 × 72 in
With its 47-inch width, this Persilux is the lineup’s clearest choice for a wide window that needs a single shade rather than a narrower panel. Its blackout fabric and thermal coating are designed to limit light and help with UV protection and insulation, while the frosted aluminum valance gives the top edge a finished appearance. Compared with the 34-inch AOSKY roller, Persilux covers a wider opening; unlike Joydeco, it uses a roller format rather than a cellular structure. The listed 100% blackout claim describes the fabric’s coverage, but the fabric is 0.8 inches narrower than the valance, so buyers should check how that affects their intended fit. It also relies on manual operation and requires spot cleaning.
Pros:- Wide 47-inch size can cover more window than the 34-inch AOSKY.
- Blackout fabric and thermal coating support light, UV, and insulation control.
- Cordless free-stop control adjusts to the desired height.
- Inside or outside mounting hardware is included.
Cons:- Fabric is 0.8 inches narrower than the valance.
- Manual operation may not suit hard-to-reach windows.
- Care details are not specified beyond the included mounting information.
Best for: Buyers with a wide window who want a cordless blackout roller blind with a valance and flexible mounting.
Not ideal for: People who need motorized operation or want the fabric to match the valance width exactly.
- Size:47 in W x 72 in H
- Color:White
- Opacity:Blackout
- Operation:Manual, cordless free-stop
- Mounting:Inside or outside mount
- Material:Aluminum
- Additional features:Thermal insulation, UV protection
- Included components:Mounting hardware, user manual
Our verdict“Choose Persilux for a wide window and valance-finished roller style, after checking the narrower fabric coverage against your opening.”
RUseeN Portable Blackout Window Shade, 118 × 57 in
RUseeN takes a different route from the fitted roller shades in this roundup: this is a cut-to-size, removable blackout panel, not a mechanism mounted to the window frame. The large 118-by-57-inch sheet can be trimmed for different openings, and the included adhesive tapes make installation possible without the brackets used by the AOSKY roller. A storage bag also makes it more practical for travel, temporary bedrooms, or rentals where a fixed shade is unwanted. That flexibility comes with extra work: buyers must measure and cut carefully, then attach the panel with tape. Compared with the cordless roller options, RUseeN offers easier portability but no free-stop adjustment or polished valance. It is not water resistant and requires spot cleaning.
Pros:- Large sheet can be cut to fit a range of window sizes.
- Adhesive tapes allow installation without a roller-shade mounting system.
- Storage bag supports portable and temporary use.
- Silver-gray backing is designed to block sunlight and UV rays while reducing heat.
Cons:- Requires careful measuring and cutting for a custom fit.
- Adhesive installation does not offer the adjustable positioning of cordless rollers.
- Not water resistant and spot-clean only.
Best for: Renters, travelers, and families needing temporary blackout coverage that can be trimmed to fit different windows.
Not ideal for: Buyers seeking a reusable, adjustable roller shade with a neat fixed installation and no cutting.
- Dimensions:118 x 57 in (300 x 145 cm)
- Material:100% polyester
- Lining:Integrated blackout polyester lining
- Color:Black
- Installation:Adhesive tapes; cut to size
- Included:Shade, ruler, 30 adhesive tapes, storage bag
- Care:Spot clean
- Package weight:0.55 kg
Our verdict“Choose RUseeN for portable, custom-fit blackout coverage; choose a fitted roller such as AOSKY for a more adjustable everyday window treatment.”
AOSKY Blackout Cordless Roller Shade, 23 × 72 in, Black
For a narrow window that needs a straightforward darkening solution, this 23-inch cordless roller shade is a more compact choice than the wider LazBlinds 34 × 64 in cellular shade. Its blackout polyester fabric blocks sunlight and UV rays, while the thermal backing may help limit heat loss. The spring-loaded lift can be stopped at different heights, so you can admit some daylight without leaving the shade fully raised. The main fit tradeoff is that the fabric is one inch narrower than the listed shade width, which can leave light gaps at the sides; an outside mount may help cover more of the window. It also needs at least two inches of frame depth for installation and is not water resistant, making it a poor choice for damp locations.
Pros:- Blackout fabric blocks sunlight and UV rays
- Thermal backing may help reduce heat loss
- Cordless spring mechanism adjusts to different heights
- Inside- or outside-mount installation offers some flexibility
Cons:- Fabric is one inch narrower than the listed shade width, which can allow side light
- Requires at least two inches of frame depth
- Not water resistant and limited to spot cleaning
Best for: Buyers with a narrow bedroom or office window who want a cordless, adjustable roller shade and have enough frame depth to mount it.
Not ideal for: People seeking near-total edge-to-edge darkness, or anyone fitting a shallow frame or a window exposed to moisture.
- Shade size:23 × 72 in
- Fabric size:22 × 72 in
- Material:100% polyester
- Opacity:Blackout
- Operation:Manual, cordless
- Mounting:Inside or outside mount
- Features:Thermal insulation and UV protection
- Care:Spot clean only
Our verdict“Choose it for a narrow, dry window where cordless height adjustment matters more than fully covering the window edges.”
Persilux Cordless Blackout Roller Shade, Linen Fabric, Custom Size, Cream
The custom sizing makes this Persilux a useful option when a standard-width shade is unlikely to fit your window. Its cream linen fabric gives it a softer look than the black Persilux shade with valance, while the cordless lift stops at any height for flexible light control. A magnetic bottom rail is designed to keep the shade steady, which can help reduce movement once it is lowered. Like the AOSKY 23 × 72 in roller shade, though, the fabric does not span the full listed shade width: here the difference is 0.8 inches, so a narrow strip of side light may remain. There is no listed valance or thermal coating, making this a more understated custom roller shade than the valanced Persilux, rather than the stronger pick for covering hardware or adding insulation features.
Pros:- Custom sizing can suit windows outside common standard dimensions
- Cordless lift can stop at any height
- Magnetic bottom rail helps keep the shade stable
- Inside- or outside-mount options suit different window setups
Cons:- Fabric is 0.8 inches narrower than the listed shade width, leaving potential side gaps
- Custom sizing requires selecting the customization option
- No valance or thermal coating is listed
Best for: Buyers with a nonstandard window who want a custom-sized blackout roller shade in a light, linen-style cream finish.
Not ideal for: Shoppers who want a ready-to-order standard size, a valance to conceal the roller, or the Persilux model’s stated thermal coating.
- Size:Custom size
- Material:Linen fabric
- Color:Cream
- Opacity:Blackout
- Fabric width:0.8 in shorter than shade width
- Operation:Manual, cordless
- Mounting:Inside or outside mount
- Included components:Shade, brackets, screws, handle, instructions, magnets
Our verdict“Pick this Persilux when a custom width and cream linen appearance matter more than a valance or extra thermal features.”
Persilux Cordless Blackout Roller Shade with Valance, Custom Size, Black
This Persilux pairs custom sizing with a valance, making it the better fit than the cream linen Persilux for buyers who want the roller hardware covered. Its black polyester lining has a thermal coating for UV protection and insulation, adding a practical layer beyond light blocking. The cordless free-stop control also lets you set the shade at different heights without a chain. The tradeoff is that the fabric is 0.8 inches narrower than the valance, so the valance does not mean the fabric itself covers the full listed width; side light may still get through. Unlike the no-drill LazBlinds cellular shades, this model needs mounting hardware and configuration for a custom size. It is also not water resistant, so I would keep it away from moisture-prone windows.
Pros:- Custom sizing accommodates nonstandard windows
- Valance conceals the roller hardware
- Thermal coating provides UV protection and insulation
- Cordless free-stop adjustment avoids cords and chains
Cons:- Fabric is 0.8 inches narrower than the valance, so side light may remain
- Custom sizing requires configuration before ordering
- Not water resistant
Best for: Buyers ordering a custom-width bedroom or living-room shade who want a black finish, covered roller hardware, and thermal coating.
Not ideal for: Renters who cannot use mounting hardware, shoppers wanting a quick standard-size purchase, or anyone needing a shade for a damp room.
- Size:Custom size
- Color:Black
- Materials:Aluminum and polyester lining
- Opacity:Blackout
- Control:Cordless free-stop
- Mounting:Inside or outside mount
- Included:Mounting hardware, user manual, valance
- Water resistance:Not water resistant
Our verdict“Choose this model for a custom-fit roller shade with a valance and thermal coating, provided you can mount it and accept possible side gaps.”
LazBlinds No-Drill Cordless Blackout Cellular Shade, 22 x 36 in, White
For renters or anyone avoiding holes in a window frame, this no-drill, no-tools installation is the main reason to choose this compact LazBlinds cellular shade. Its blackout fabric and honeycomb cells are designed to block sunlight while helping reduce heat transfer and noise—advantages the AOSKY 23 × 72 in roller shade does not specifically list. The fit is more restricted, however: this version is made for an inside-mounted window measuring 21.7–22.6 inches wide and 36 inches high. Unlike the Persilux custom roller shades, it does not offer outside mounting or custom sizing to work around an unusual opening. The white finish also suits buyers who want the shade to blend into a light interior, but the supplied details specify spot cleaning only. Check the window dimensions carefully before choosing it.
Pros:- Installs without drilling, tools, screws, or brackets
- Cordless operation avoids hanging cords
- Blackout fabric supports privacy and blocks sunlight
- Cellular construction helps insulate against heat, cold, and noise
Cons:- Inside mounting only
- Fits a narrow, specific window-size range
- Spot cleaning only
Best for: Renters and tool-averse buyers with an inside-mount window measuring 21.7–22.6 inches wide by 36 inches high.
Not ideal for: People with an outside-mount setup, a window outside the stated fit range, or a preference for washable window coverings.
- Window size fit:21.7–22.6 in W × 36 in H
- Actual shade size:21 5/8 in W × 36 in H
- Color:White
- Material:Polyester
- Opacity:Blackout
- Mounting:Inside mount
- Installation:No-drill, no-tools
- Care:Spot clean only
Our verdict“Choose it for a correctly sized window when avoiding installation holes and gaining cellular insulation are higher priorities than mounting flexibility.”
LazBlinds No-Drill Cordless Blackout Cellular Shades, 34 × 64 in, White
This larger LazBlinds brings the same no-drill cellular design as the 22 × 36 in version to a wider window, making it the more suitable of the pair for bedrooms or living spaces with a broader opening. Its honeycomb structure helps limit heat and cold transfer and reduce noise, while the blackout lining blocks sunlight and UV rays. That makes it a stronger fit for insulation-minded buyers than the AOSKY 34 × 72 in roller shade, which is a roller style rather than a cellular blind. The fit remains exacting: the intended window width is 33.7–34.6 inches, and installation is inside-mount only. Its 64-inch height also differs from the shorter LazBlinds model’s 36-inch height, so check the full opening rather than relying on width alone.
Pros:- Installs without tools or drilling
- Blackout lining blocks sunlight and UV rays
- Honeycomb cells help insulate against heat and cold and reduce noise
- Cordless manual operation avoids hanging cords
Cons:- Inside mounting only
- Fits a limited window-width range
- The 64-inch height may not suit taller openings
Best for: Renters or homeowners with a 33.7–34.6-inch-wide inside-mount window who want blackout coverage and cellular insulation without drilling.
Not ideal for: Buyers needing outside mounting, a custom width, or a window outside the specified fit range.
- Shade size:34 × 64 in
- Actual blind size:33 5/8 in W × 64 in H
- Window fit:33.7–34.6 in W × 64 in H
- Color:Blackout white
- Material:Polyester
- Opacity:Blackout
- Mounting:Inside mount only
- Installation:No tools or drilling required
Our verdict“Pick this larger cellular shade for a correctly sized wider window when tool-free installation and insulation matter more than mounting flexibility.”
How We Picked
I ranked these options by how well their stated formats address common blackout-blind decisions: window fit, light-blocking coverage, installation constraints, and day-to-day ease of use. I gave preference to options that offer a clear use case, such as a cordless roller for a standard window, a custom-size shade for a less typical opening, or a no-drill model for a rental. A valance, fabric style, or cellular construction matters only when it solves a practical need; none guarantees a light-tight result around the edges.
The order reflects how broadly useful each type is, rather than a claim that every blind will perform identically in every room. Standard fixed-size shades rank well for shoppers with matching windows, while custom sizing and portable panels serve narrower but meaningful needs. I also weighed the tradeoffs: portable panels require cutting, no-drill choices are available in specific dimensions, and a mounted shade can leave light gaps if the fit and mounting position are wrong. The product details provided do not establish comparative lab performance, so I avoid treating any option as proven to block every trace of light.

Factors to Consider When Choosing Best Blackout Blinds
Before choosing from these blackout blinds, start with the window rather than the product label. A shade can use blackout fabric and still leave bright strips at the sides or top if its dimensions and mounting position do not suit the opening. These factors can help you avoid buying a style that looks right but does not meet your room’s needs.
Measure the Window and Choose a Mount
Measure the window where the blind will sit, then check the manufacturer’s instructions for whether the listed width refers to the fabric or the full assembly. That distinction affects how much of the opening the shade covers. An inside mount can look neat, but a shallow frame or handles may interfere with the shade or leave more light around the edges. An outside mount can cover beyond the frame, though it needs suitable wall space and may look larger. Do not assume a shade labeled for a given width will fit every opening of that width. When dimensions are unusual, custom sizing may be a better route than trying to adapt a close standard size. For portable cut-to-size panels, plan the trim carefully before cutting because that choice is less easily reversed.
Think About Light Gaps, Not Just Fabric
“Blackout” describes the shade material or intended use, not necessarily a fully dark room. Light can still enter around the headrail, sides, or bottom, especially when a shade is mounted inside the frame. If you sleep during the day or need a darker nursery, compare how the product is meant to cover the window and consider whether an outside mount is practical. A valance can cover the top mechanism, but it does not by itself seal the sides. Also check for nearby trim, vents, and window hardware that could prevent the shade from sitting close to the opening. Where small light leaks matter, a separate side-channel or curtain solution may be needed. Prioritize coverage and fit over a dark fabric color.
Match the Install Method to Your Home
Mounted cordless shades generally provide a more finished look than a temporary panel, but they require a suitable mounting surface and some installation work. No-drill models can be appealing in rentals or homes where you want to avoid making holes, though they are limited to their available sizes and mounting conditions. Check the product instructions for frame depth, surface compatibility, and any restrictions before ordering. Portable panels avoid a fixed blind installation and can suit temporary stays, but they involve positioning and trimming rather than a simple raise-and-lower routine. If you expect to move the shade between windows, a portable option may be easier to repurpose than a fitted blind. Choose the approach that matches how long you will use it and how much setup you are willing to do.
Choose a Style You Can Use Every Day
Cordless operation removes dangling lift cords and gives the window a cleaner appearance, but the shade still needs to be easy to reach and operate from its bottom rail. Consider who will use it, how often it will be raised, and whether a window is above a bed or furniture. Roller shades have a simple profile and take up less visual space than many layered window treatments. Cellular shades have a different construction and may appeal to buyers who prefer that look, but fit and installation still come first. A valance can conceal the roller mechanism and create a more finished appearance, while adding a more prominent top profile. Let the room’s use and window layout guide the style instead of assuming one construction suits every room.
Decide Between Fixed Sizes and Custom Sizing
Fixed-size blinds make sense when your window closely matches a listed dimension and you want a direct, uncomplicated choice. Before ordering, verify the full height as well as the width; a shade that is wide enough may still fall short of the area you need covered. Custom sizing gives you more control over fit, especially for windows that fall between common dimensions, but it adds a measurement step and can make choosing less forgiving. Compare the ordering instructions carefully, including whether measurements should be taken to the nearest fraction or rounded. A portable cut-to-size shade offers another path, but it trades a made-to-fit finish for hands-on trimming. If you are uncertain about measuring, check the seller’s guidance before committing to a custom or cut-to-size option.
Set Expectations for Room Darkening
Room darkness depends on more than the blind: window orientation, outdoor lighting, frame gaps, and the time of day all affect the result. A blackout shade can reduce incoming light without making a room completely dark, particularly when mounted inside the frame. For a bedroom, decide whether your goal is fewer early-morning rays or the darkest possible sleep environment; the latter may call for added coverage at the sides. In a nursery, a cordless design may be appealing, but installation and a secure fit still deserve careful attention. In a rental, an easy-to-remove solution may matter more than a tailored built-in look. Paying more for customization makes most sense when a poor fit would undermine the shade’s main purpose.
Frequently Asked Questions
Will blackout blinds make my bedroom completely dark?
Not necessarily. Blackout fabric can block light through the material, while light may still enter around the edges, headrail, or bottom. An inside-mounted blind often leaves more perimeter exposure than an outside-mounted one, depending on the window and product. If you need a very dark room for daytime sleep, check the coverage dimensions and mounting instructions before ordering. You may need extra side coverage or curtains to reduce remaining gaps.
Should I choose a standard-size blind or a custom-size one?
Choose a standard size when your window matches the product’s stated measurements and the mounting instructions support that fit. Custom sizing is useful when a window falls between common dimensions or when edge coverage matters more than a quick, fixed-size choice. Measure carefully and confirm whether the listed width includes the brackets or headrail. If measuring feels uncertain, review the seller’s measurement guide before placing a custom order. A close but incorrect size can leave gaps that fabric choice alone cannot fix.
Are no-drill blackout blinds a good choice for renters?
They can be a practical choice when you want to avoid making holes, but compatibility depends on the window frame and the product’s mounting method. Check the required frame depth, surface type, and supported dimensions before buying. No-drill options in this roundup are offered in specific sizes, so they may not cover every rental window. Also consider whether the shade can be removed without damage under your lease or building rules. If the frame does not suit the mounting system, a portable panel may be a more flexible alternative.
Do portable cut-to-size shades work better than fitted blinds for unusual windows?
A portable panel can suit an unusual opening because it is designed to be trimmed rather than ordered in a fixed blind size. That flexibility comes with a less tailored finish and the need to measure and cut accurately. Fitted blinds are generally neater for windows that match a standard or custom dimension, but they involve choosing a mounting style and installing hardware. Think about whether you need a temporary solution or a blind you will raise and lower every day. For a permanent, frequently used window, a properly sized fitted shade is often the more convenient format.
What should I do if my blackout blind still lets in light?
First identify where the light is entering: through the fabric, around the sides, above the headrail, or below the shade. If it comes around the edges, the blind may be too narrow for your mounting position or the window may need additional coverage. Check that the shade is installed as directed and that nearby handles or trim are not pushing it out of place. A valance can address some light at the top, but it will not close side gaps. For a bedroom that needs stronger darkness, consider adding curtains or another form of perimeter coverage rather than replacing a functioning shade solely because of its fabric label.
Conclusion
For a broadly useful choice among these options, I’d start with the AOSKY 34 × 72-inch cordless roller shade if that size suits the window. Shoppers seeking a more tailored fit should look at the Persilux custom-size shades; they are my premium pick for buyers prepared to measure carefully. The Petaholic portable shade is the value-minded option for temporary use or a window that does not suit a standard blind, while the LazBlinds no-drill cellular shades are the most approachable starting point for renters who want to avoid drilling and have a compatible window. For a compact opening, compare the smaller AOSKY and LazBlinds sizes against your exact measurements before ordering. Whichever style you choose, match the mounting method and coverage to the window first—blackout fabric alone cannot close gaps around a poor fit.
