The best inside mount blackout shade depends on your window’s exact measurements, preferred appearance, and need for cordless adjustment. The AOSKY 23-inch shade is best for narrower openings, while the 34-inch AOSKY and SUNOFF options suit wider measured openings. Persilux is a compact option with a decorative valance, and TWODRAPES offers a linen-style look. Before buying any of these shades, confirm that the product’s mounting instructions and dimensions work for your window’s inside frame.
| Shade | Listed size | Best for |
|---|---|---|
| AOSKY Cordless Blackout | 34″W x 72″H | Free-stop adjustment and thermal coating |
| SUNOFF Cordless Blackout | 34″W x 72″H | Valance and stated 100% blackout fabric |
| AOSKY Indoor Roller Shade | 23″W x 72″H | Narrower windows |
| Persilux Blackout Roller Shade | 15″W x 64″H | Small openings and a finished valance |
| TWODRAPES Linen Blackout Shade | 34″W x 72″H | Linen-style appearance |
AOSKY Cordless Blackout Roller Shade
This 34-by-72-inch shade is best for buyers seeking cordless, adjustable light control in a wider window opening. Its free-stop system is designed to hold the shade at a chosen height without a chain or cord. The listed features also describe low-noise operation and fabric with a heat-insulation coating for light blocking, UV protection, and thermal insulation.
Choose this model if cordless operation and a simple roller-shade design are priorities. The product information does not specify the fabric width or confirm inside-mount clearance requirements, so measure the window and check the seller’s mounting guidance before ordering. Its black color may not suit buyers seeking a light, neutral finish.
SUNOFF Blackout Shade With Valance
The SUNOFF shade is best for buyers who want a 34-by-72-inch cordless roller blind with a top valance. Its stated features include 100% blackout fabric, a thermal insulation coating, and a free-stop system for setting the shade at different heights. The aluminum lower rod and valance are described as matching the fabric, while hidden mounting accessories conceal the mechanism.
Choose this option if a covered-looking roller mechanism is more important than a minimal, exposed roller. The product’s blackout claims describe the fabric; actual light at the edges can depend on the window and installation. Confirm that the shade and hardware fit your inside frame before purchase.
AOSKY 23-Inch Blackout Roller Shade
This AOSKY model is best for narrower windows because its listed blind size is 23 by 72 inches. The product specifies a 22-inch fabric width, an important distinction when comparing shade coverage with the overall blind size. Its polyester fabric has a reinforced thermal coating, and the listing describes a cordless spring-loaded mechanism that can stop at a selected height.
Choose it if the stated fabric width suits your opening and you want a compact black shade. The product listing claims that the fabric blocks sunlight and UV rays and helps reduce heat loss. The 22-inch fabric width is narrower than the listed 23-inch blind size, so account for that difference when planning an inside mount.
Persilux Cordless Shade With Valance
Persilux is best for buyers fitting a smaller opening: the listed size is 15 inches wide by 64 inches high. Its features include blackout fabric, a built-in thermal coating, UV protection, and a cordless free-stop system. A frosted aluminum valance and fabric-wrapped bottom rail give the shade a coordinated, finished appearance.
Choose this model when its compact dimensions match your measured window and you prefer a valance. Avoid selecting it for a wider opening based on appearance alone; the listed width is 15 inches. The product information does not state a separate fabric width, so verify the measurement and installation details with the seller.
TWODRAPES Linen-Style Blackout Shade
This 34-by-72-inch shade is best for buyers who want a softer, linen-style look rather than a plain black finish. The listing describes blackout linen fabric, cordless free-stop adjustment, UV protection, and thermal insulation. A matching fabric valance wraps the top shell, and the bottom rod is also fabric-wrapped for a coordinated appearance.
Choose TWODRAPES if its beige oatmeal color and textured style fit your room. Its integrated valance is designed to cover the top shell, but an inside mount still requires checking frame depth and hardware clearance. The listing does not provide a separate fabric-width measurement, so confirm the coverage dimensions before ordering.
Buying Guide: How to Choose Inside Mount Blackout Shades
How should you measure an inside mount?
Measure the inside width of the window frame at the top, middle, and bottom, then use the narrowest measurement when comparing it with the product’s sizing instructions. Measure the height at more than one point as well. Check the listing for whether the stated width refers to the complete shade or the fabric; the AOSKY 23-inch model, for example, lists a 23-inch blind and 22-inch fabric.
Do not assume every shade labeled for windows will fit inside every frame. Confirm that the product includes suitable mounting hardware and that your frame has enough depth and clearance for the brackets and roller mechanism. The provided product details do not establish a universal inside-mount fit.
What matters most for blackout performance?
Look for a clear fabric light-blocking claim and compare how each design handles the top and bottom of the shade. SUNOFF and TWODRAPES describe valances, while Persilux lists a valance and wrapped bottom rail. Even blackout fabric may not prevent all light around the perimeter of an inside-mounted shade because the fit leaves room for installation.
Should you choose a cordless shade?
All five products describe cordless adjustment. Their free-stop systems are intended to let users set a preferred height without a hanging cord. Compare the listed control mechanism and finish, and follow the product’s installation and use instructions, particularly in homes with children or pets.
Which shade is right for a narrow window?
Compare the measured opening with the listed shade and fabric widths. The AOSKY model with a 22-inch fabric width and the 15-inch Persilux model are the narrower options in this selection. The 34-inch shades are intended for wider openings, subject to the manufacturer’s measurement and mounting directions.
Frequently Asked Questions
Can blackout shades be installed inside a window frame?
They can be used for an inside mount only if the shade dimensions, mounting hardware, and frame depth are suitable. Check the specific product instructions rather than assuming compatibility.
Do blackout shades block every bit of light?
Blackout fabric is designed to block light through the material, but gaps around the edges can still let light into a room. Fit and installation affect the result.
What is the difference between shade width and fabric width?
Shade width can refer to the full assembly, while fabric width refers to the material covering the window. AOSKY lists 23 inches for the blind and 22 inches for the fabric on its narrower model.
Are these shades cordless?
Yes. Each product listing describes cordless operation, including free-stop adjustment on the models that specify that feature.
Which option includes a valance?
SUNOFF and Persilux describe valances, and TWODRAPES describes an integrated fabric valance. Check the individual listing for the exact design and mounting details.
