Joydeco Blackout Cellular Shades, 46" x 64

For a bedroom where early daylight makes it harder to sleep, or a home office where glare gets in the way, blackout cellular shades offer a way to adjust light without adding cords or drilling into the window frame. Joydeco’s black shade uses a tension-mounted design and a cordless lift, so it may suit renters or anyone who wants a cleaner-looking window. The listed size is 46 inches wide by 64 inches high, getting the fit right matters because gaps around the shade can let light through.

Key points

The honeycomb shade is designed to block 99% of light while filtering UV rays. That makes it worth considering for a light-sensitive sleeper or a room that gets strong daylight, though the claimed blackout performance depends in part on how closely the shade fits the opening. The cellular construction is also described as noise-reducing and insulating, but the product details don’t quantify either effect, so treat those as supporting benefits rather than a substitute for dedicated soundproofing or insulation.

The cordless design keeps dangling cords out of the way, and the free-stop system lets you pause the shade at different positions. For example, raise it partway during the day to admit light, then pull it down for more privacy in the evening. The top and bottom tracks are aluminum, while the fabric is described as sturdy and lightweight. Installation is tension-mounted and drill-free, the listed setup time is 30 seconds, though the window still needs to suit this mounting approach.

Fit and sizing

This shade measures 46 inches wide by 64 inches high. For an inside mount, measure the window frame’s interior width before choosing it: the shade should be no wider than that opening. The product guidance says to allow no more than a half-inch reduction from the window size. A close fit is especially relevant here because even a blackout shade can leave light at the edges if it doesn’t cover the opening well.

Keep in mind that an inside mount with an unsuitable or uneven opening may not deliver the intended light blocking, and no outside-mount dimensions are provided. It suits you if your frame can accommodate the listed width and height and you want a no-drill, cordless setup. It might not be a great match if your window opening is smaller or you need exact fit guidance beyond the dimensions supplied.

Tips for day-to-day use

Use the free-stop design to set the shade at the height that fits the moment rather than choosing only between fully open and fully closed. In a home office, a partial lift can bring in daylight while keeping the lower part of the window covered, at bedtime, lowering it fully is the straightforward way to reduce incoming light. The shade can be repositioned as needed, without managing a pull cord.

For installation, measure the inside of the frame carefully before mounting and compare it with the shade’s dimensions. The product describes a quick tension-mounted setup, but an accurate measurement is still the part that determines whether it fits. The 99% light-blocking figure is a product claim, not a promise that every window will become completely dark, edge gaps and the window itself can affect the result.

Before you decide

Does it need screws or a drill? The listed installation method is tension-mounted and drill-free. The window opening must still be suitable for that setup.

Can you stop it partway up? Yes. The free-stop system is described as allowing the shade to stay at different positions.

Is it completely cordless? The product is described as cordless, with no lift cord to manage. Its black color and cellular construction are the details provided for this size.

When it makes sense

Choose this Joydeco shade if you want a cordless blackout option, prefer not to drill, and have a window opening that matches 46 by 64 inches. Its adjustable stopping positions add flexibility for rooms used throughout the day, while the cellular design brings insulation and noise reduction into the product’s stated benefits. On the spec sheet, the key tradeoff is fit: if the measurements don’t work for your frame, or you need documented performance beyond the stated light-blocking claim, another shade with a better-matched size or more detailed specifications would be a more sensible purchase.
