Blackout pull down window shades can make a bedroom, nursery, or home office darker and more private, but the fit matters as much as the fabric. The shades below offer cordless operation and light-blocking or thermal features, with differences in valance style, sizing guidance, and coverage. Before choosing, check whether you plan to mount the shade inside or outside the window frame: fabric is often narrower than the listed shade size, which can leave light gaps.

Our Picks: Best Blackout Pull Down Window Shades reviews
1. Persilux Cordless Blackout Roller Shade with Valance
The Persilux combines blackout fabric with a thermal coating and a square aluminum valance. The valance covers the roller mechanism for a more finished appearance, while the fabric-wrapped bottom rail keeps the lower edge coordinated with the shade.
Its free-stop system lets you pull the shade to a chosen height without a cord or chain. The listing says the shade can be mounted inside or outside the frame and offers a custom-size option. Note that the fabric is 0.8 inches narrower than the valance, so use the fabric width—not just the overall shade width—when planning coverage.
This is a strong option if you want a tailored look and flexibility in sizing. As with other roller shades, an inside mount may leave light along the edges; a wider outside mount can provide more coverage if your wall and trim allow it. The product listing describes the fabric as offering 100% blackout, but the fit around the window also affects how dark the room becomes.
Pros:
- Blackout fabric with thermal coating for insulation and UV protection
- Free-stop cordless adjustment
- Square aluminum valance and fabric-wrapped bottom rail
- Inside- or outside-mount setup and custom sizing option
Cons:
- Fabric is narrower than the valance, so measure carefully for light coverage
- Custom sizing requires selecting the customization option
Verdict: Choose the Persilux if you want blackout fabric, a finished valance, and the option to customize the shade size.
2. SUNOFF Cordless Blackout Shade with Aluminum Valance
This SUNOFF model is listed at 34 inches wide by 72 inches high and pairs blackout fabric with a thermal insulation coating. Its aluminum valance and lower rod match the fabric, and the hidden mounting accessories help conceal the shade mechanism.
The free-stop design adjusts with a gentle pull and does not use a traditional cord or chain. SUNOFF says the shade works for inside or outside mounting and has a waterproof coating that can be wiped clean. These details make it a practical pick for rooms where you want simple operation and a neat, low-profile appearance.
The listing does not specify how much narrower the fabric is than the overall shade size, so confirm the product’s dimensions before ordering. If you need the darkest possible result, consider an outside mount that extends beyond the frame, provided the window area has enough flat mounting space.
Pros:
- Blackout fabric with thermal insulation coating
- Cordless free-stop operation
- Matching aluminum valance and lower rod
- Listing states the coating is waterproof and easy to clean
Cons:
- Check the exact fabric coverage before choosing a size
- The listed dimensions may not suit narrower windows without a different size option
Verdict: The SUNOFF is worth considering if its listed size fits your window and you prefer a concealed mechanism with a coordinated aluminum valance.
3. AOSKY Blackout Cordless Roller Shade for Standard Windows
The AOSKY is a 23-by-72-inch cordless roller shade made with polyester fabric and a thermal-insulated coating. Its spring-loaded mechanism is designed to hold the shade at different heights, and the listing describes a pull-to-lower, gentle-pull-to-close operation.
Pay close attention to the sizing notes: the fabric is 22 inches wide, one inch narrower than the listed shade size. For an outside mount, AOSKY recommends ordering a shade wider than the window; for an inside mount, the product size should be the same as or slightly narrower than the window width. The listing also calls for at least two inches of frame depth for installation.
This model may suit a standard window if its dimensions match your measurements. The main trade-off is that its set size and narrower fabric leave less room for error than a custom-width option. The supplied description says the thermal backing helps limit heat loss and blocks sunlight and UV rays, but edge gaps can still let light into the room.
Pros:
- Thermal-coated polyester fabric
- Cordless spring mechanism with adjustable stopping positions
- Installation hardware and instructions are included
- Clear guidance for inside- and outside-mount sizing
Cons:
- Fabric is one inch narrower than the listed shade width
- Requires at least two inches of frame depth for installation
Verdict: Pick the AOSKY if its fixed 23-by-72-inch size fits your window and you want a straightforward cordless shade with thermal backing.
4. ChrisDowa White Blackout Roller Shade with Cordless Spring
This ChrisDowa shade has a simple white design, blackout fabric, and a white backing. Its spring-loaded cordless mechanism is intended to let you pull the shade down to the height you want, then gently pull the buckle to close it.
The product is listed at 22 by 72 inches, but the fabric is 0.6 inch narrower than the selected shade size. For an inside mount, the frame needs at least two inches of depth, and the listing warns that small side light gaps are possible. For more coverage, ChrisDowa recommends an outside mount that is wider and longer than the window.
The white backing and clean appearance may fit well where you want a neutral shade. Its listed uses include bedrooms, living areas, kitchens, bathrooms, French doors, and offices. The supplied product details also describe thermal backing for limiting heat transfer, but the amount of light blocked in a finished room depends on how closely the shade covers the window.
Pros:
- Blackout fabric with white backing
- Cordless spring-loaded operation
- Installation hardware and instructions are included
- Can be mounted inside or outside the frame
Cons:
- Fabric is 0.6 inch narrower than the selected shade size
- Inside mounting may leave light gaps at the sides
Verdict: The white ChrisDowa is a practical choice for a window that matches its dimensions, especially if you can use an outside mount for broader coverage.
5. ChrisDowa Striped Textured Blackout Roller Shade
This ChrisDowa version adds a striped texture to its blackout-style fabric and includes an aluminum bottom rod. The cordless spring mechanism is designed to hold the shade at a chosen position, with a gentle pull on the buckle to close it.
The listed size is 30 by 72 inches, while the fabric is 0.6 inch narrower. The listing says the fabric blocks most sunlight and UV rays, so it is better to think of this model as a light-reducing option rather than assume it will create complete darkness. An outside mount can help reduce side gaps, but the shade needs a flat, level mounting surface.
The product data currently lists this shade as unavailable. Its textured design may appeal if you want more visual detail than a plain roller shade, but check the listing before planning around it. The shade’s listed dimensions and mounting requirements should also be compared with your window before purchase.
Pros:
- Striped textured fabric for a more decorative look
- Cordless spring mechanism
- Aluminum bottom rod
- Can be mounted inside or outside the window frame
Cons:
- Listed as unavailable in the supplied product information
- Product description says it blocks most sunlight, not all sunlight
Verdict: Consider this ChrisDowa model only if its textured style suits your room and the listing becomes available; choose another option if you need a shade now or want the clearest stated blackout claim.
How to Choose Blackout Pull Down Window Shades
Measure the window and shade separately
Measure the window opening in more than one place, since frames may not be perfectly even. Then compare those measurements with the product’s overall shade size and its fabric width. The fabric may be narrower than the listed shade width because the overall measurement can include the roller or mounting hardware. For example, the AOSKY fabric is one inch narrower than its shade size, while the two ChrisDowa models list fabric that is 0.6 inch narrower.
Decide between inside and outside mounting
An inside mount sits within the frame and gives the window a built-in look, but it can leave small gaps along the edges. Check the frame depth needed for the brackets; AOSKY and the white ChrisDowa specify at least two inches. An outside mount attaches beyond the frame and can cover more of the window area. It needs enough flat space around the window, so measure that area before ordering.
Set expectations for room darkness
Blackout fabric can reduce light through the material, but light may still come around the sides, top, or bottom. If darkness is a priority for sleep or shift work, plan for broad coverage and consider an outside mount where practical. Also compare the product’s own light-blocking description: the striped ChrisDowa listing says it blocks most sunlight, while the other product descriptions make stronger blackout claims.
Choose the control style and safety features
Each shade in this comparison is cordless. The Persilux and SUNOFF use a free-stop design, while AOSKY and the ChrisDowa shades describe spring-loaded operation. Cordless controls avoid dangling cords and allow the shade to be adjusted by hand. Look at the product instructions for its specific opening and closing method before installation.
Consider insulation, cleaning, and room placement
Several options describe thermal coatings or insulated backing intended to help limit heat transfer through the window. These features may matter in a bedroom or office where temperature and light control are priorities. For easier care, the SUNOFF listing says its coating is waterproof and easy to clean, while the white ChrisDowa listing recommends wiping the shade with a damp cloth. Follow the care instructions for the model you choose.
Check the finish and mounting surface
A valance can hide the roller mechanism and give the window a more finished appearance; both the Persilux and SUNOFF include one. The striped ChrisDowa adds a patterned fabric, while the white ChrisDowa has a plain neutral look. For outside mounting, confirm that the brackets can attach to a flat, level surface. The striped ChrisDowa listing specifically cautions against curved trim, angled surfaces, and textured walls.
Frequently Asked Questions
Do blackout roller shades make a room completely dark?
Not always. Blackout fabric can block light through the shade, but light can still enter around the edges or through uncovered parts of the window. Careful measuring and a wider outside mount can help reduce gaps.
Is inside or outside mounting better for blackout coverage?
An inside mount offers a neat fit within the frame but may leave narrow gaps on the sides. An outside mount can cover more of the window, if you have enough flat space around the frame and choose a shade wide enough for the opening.
Why is the fabric narrower than the shade size?
The overall shade measurement can include the roller and mounting hardware, not just the fabric. Check the listed fabric width as well as the full shade width so you know how much of the window the material will cover.
Are cordless pull down shades suitable for homes with children or pets?
These products use cordless controls rather than traditional hanging cords or chains. That removes dangling cords from the design, but you should still follow the manufacturer’s installation and use instructions.
Can these shades help with heat and cold near a window?
Several listings describe thermal coatings or insulated backing intended to reduce heat transfer. The product information does not quantify the amount of energy savings, so results will depend on factors such as window construction, fit, and room conditions.
How should I clean a blackout roller shade?
Follow the care instructions for the model you buy. The SUNOFF listing describes its coating as easy to clean, and the white ChrisDowa listing recommends wiping with a damp cloth. Avoid assuming every fabric has the same cleaning requirements.
Final Recommendation
The Persilux is the most flexible pick here if you want a valance, cordless free-stop control, and a custom-size option. The SUNOFF is a good alternative for a coordinated aluminum finish, while the AOSKY and white ChrisDowa suit shoppers whose windows match their listed dimensions. Whichever you choose, compare the fabric width—not only the overall shade size—and decide whether an inside or outside mount will give you the coverage you need.
