Cheap Blackout Curtains

Cheap blackout curtains fail in one specific way: they say “blackout” on the package, then let in a glowing rectangle of morning light around every edge. The products below actually block light. They’ve been picked from thousands of verified reviews, tested by shift workers who literally can’t afford bad blackout performance, and priced under $30 for a standard window.

The Difference Between “Room Darkening” and True Blackout

This distinction matters more than any other spec. Room darkening curtains block roughly 70–85% of light. That sounds like a lot until 7 AM sunlight wakes you up through what you thought were blackout curtains.

True blackout panels use triple-weave or foam-backed fabric that blocks 95–99% of incoming light. You can tell the difference by holding the panel up to a light source — if you can see light through the fabric at all, it’s room darkening, not blackout.

For shift workers, nurseries, or anyone sensitive to light while sleeping, triple-weave construction is non-negotiable. For everyone else, room darkening is often good enough and usually cheaper.

Our Top Picks — Cheap Blackout Curtains

NICETOWN Thermal Blackout Curtains — $24.99 for two panels. This is the standard recommendation for a reason. Triple-weave construction, 95%+ light blocking, available in 20+ colors including blackout black, charcoal, and navy. Machine washable. They’ve been a top seller for years because they deliver on the core promise. If you need genuine blackout performance and want to pick one product, this is it.

BGment Blackout Curtains — $22.95 for a two-panel set. BGment’s double-layer construction blocks light reliably without the stiffness of foam-backed panels. Available in over a dozen colors — the neutral options (taupe, beige, gray) are the most popular. At nearly $2 less than NICETOWN, they’re a solid pick for bedrooms where you want good blackout without maximum price. The slightly lighter fabric weight makes them easier to open and close daily.

Deconovo Room Darkening Curtains — $19.99 per two-panel set. Technically room darkening at ~85%, but worth including here because the price makes them the right choice for rooms where you don’t need total darkness — just significantly less. Living rooms, home offices, and media rooms are ideal. For nurseries or night shift workers, step up to NICETOWN. For everyone else, Deconovo delivers reliable dimming at the lowest price in this category.

H.VERSAILTEX Linen Blackout Curtains — $27.99 for two panels. For bedrooms where aesthetics matter as much as performance. These have the look of woven linen while still achieving genuine blackout performance through a back layer — the front fabric is all texture and warmth, not the flat polyester most blackout curtains use. Available in natural, beige, and warm neutrals. Best pick if you’re designing around a specific room aesthetic.

NICETOWN Blackout Curtains with Tiebacks — $27.99 for a complete set including magnetic tiebacks. The tiebacks are the differentiator here — they hold panels cleanly to the side when open so they don’t flop around or sag. If you open and close your blackout curtains twice a day, the quality-of-life improvement from tiebacks is worth the slight price bump. Same blackout performance as the base NICETOWN.

Eclipse Kendall Blackout Curtains — $17.99 per single panel. The most affordable true blackout option here. Sold as single panels, so you’ll need two for a standard window ($35.98 total — slightly over budget but worth noting). Eclipse’s blackout performance is among the best in this price range, and the energy-saving properties — insulation against heat and cold — are measurably effective. Good pick for larger windows where you need multiple panels and are watching total cost.

Sizing: The Mistake That Wrecks Cheap Blackout Curtains

Most light leakage in cheap blackout curtains isn’t from the fabric — it’s from panels that are too narrow, too short, or hung too close to the window frame.

Width: One 52-inch panel does not cover a standard window. You need two panels for any window wider than 30 inches. They should overlap by 2–3 inches in the center when closed, creating a continuous light block across the full window.

Length: Go floor-length. A 1-inch gap at the bottom lets in a significant light strip in the morning. Standard 84-inch length works for 8-foot ceilings. For 9-foot ceilings, use 96-inch panels.

Hang the rod near the ceiling, not above the window frame. The gap between the window frame and the ceiling is where light bleeds in on cheap installs. Mount the rod 4–6 inches from the ceiling to eliminate it. This also makes the room feel taller, so it’s an aesthetic improvement too.

What Actually Matters for Blackout Performance

Fabric construction: Triple-weave or foam-back > double-layer > single-layer. That hierarchy holds across all price points.

Grommet vs. rod pocket: Grommets are easier to open and close and look more modern. Rod pockets block slightly more light at the top edge because the fabric folds over the rod. If maximum blackout is the priority, go rod pocket. If easy daily operation matters, go grommet.

Color: Blackout performance is in the construction, not the color. A white triple-weave panel will block as much light as a black one. Dark colors show less dust and lint, which is a practical advantage for low-maintenance bedrooms.

The wall gap: Light sneaks in around the sides of any curtain rod. The solution is returning panels to the wall — specifically, using L-shaped “return” brackets that bring the rod against the wall at each end, creating a light-sealed edge. Most budget rods include standard brackets that leave a gap. If total darkness is essential (nursery, shift worker), look for rods with return brackets or add blackout tape to seal the gap.

Best Rooms for Blackout Curtains

Bedrooms are the obvious use case — blocking sunrise light can meaningfully improve sleep quality, especially in summer when sunrise is at 5:30 AM. Triple-weave or higher.

Nurseries are the highest-stakes application. A well-rested baby means a functioning parent. Don’t compromise on performance here. NICETOWN or BGment, with a rod mounted near the ceiling.

Home theater and media rooms benefit from room darkening or true blackout to improve screen contrast. Deconovo’s 85% blocking is usually sufficient since you can control when you use the room.

Shift workers’ bedrooms have the same requirement as nurseries: actual blackout. This is not a use case for room-darkening curtains. Triple-weave + ceiling-mounted rod + overlap in the center.

Home offices where video calls on Zoom happen — even room-darkening curtains dramatically improve how you look on camera by eliminating the blown-out window background problem.

Care Instructions

Machine wash cold on a gentle cycle. Skip the dryer or use low heat — high heat damages blackout coating over time and can cause foam-backed panels to separate or crack. Hang-dry is ideal.

For wrinkles out of the package (common with all budget curtains), hang in a steamy bathroom for 20 minutes or use a handheld steamer. Ironing blackout panels directly can melt the backing — always iron with a cloth between the iron and the fabric if needed.

With proper care, budget blackout curtains last 5–7 years. The blackout performance typically holds for 3–4 years before the coating starts to degrade with heavy washing.
