The Best Blackout Curtains for Bedrooms

A dark bedroom is one of the simplest sleep upgrades you can make. Research published in the Journal of Clinical Sleep Medicine found that even dim light during sleep suppresses melatonin and cuts into REM quality, and Sleep Foundation analysis links true blackout conditions to falling asleep about 20 minutes sooner. The National Sleep Foundation's polling says roughly three-quarters of Americans think a dark room matters for good sleep, but only about 40% actually hang anything to get one. A pair of panels closes that gap in an afternoon.

Here's the part the packaging won't tell you. Almost no curtain blocks all the light, because the fabric isn't usually the problem — the gap around it is. Good Housekeeping Institute testing found panels labeled blackout ranged anywhere from 85% to 99.9%, and Bob Vila's light-meter work showed panels reading near zero at the center while still leaking at the top and sides. You can buy the densest fabric made and still wake up to a glowing halo around your window frame if the rod sits flush to the trim.

So think of these as one half of a system: the fabric does its job, and your mounting does the rest. We looked at construction, panel width, hanging style, care requirements and certifications, and we leaned on published testing and the patterns in owner feedback rather than marketing claims. We think that the NICETOWN Full Blackout Curtains are the best blackout curtains for most bedrooms, and that the Vision Home Pinch Pleat Blackout Curtains are the ones to buy if you want the room to look finished, not just dark.

Buy blackout curtains if light wakes you up, if you sleep during the day, or if you're trying to keep a toddler asleep past 5:30 a.m. They're also worth it in hot climates for reasons that have nothing to do with sleep — the Department of Energy estimates medium-colored drapes with white plastic backings cut summer heat gain by 33%, and that properly installed insulating curtains can reduce annual heating and cooling costs by as much as 25%. Windows account for a quarter to a third of home heating and cooling energy use, so this is one of the higher-return passive upgrades you can make in an afternoon.

Skip them if your bedroom already has good shades and you just want a decorative layer, or if you're renting somewhere you can't mount hardware wide enough to matter. This guide covers ready-made fabric panels sold in standard bedroom sizes. It doesn't cover cellular shades, roller blinds, custom drapery or portable travel blackout kits, all of which solve overlapping problems differently. And if total darkness is the goal, know going in that no ready-made panel gets you there alone — you'll be pairing it with a track, a wraparound rod or a valance.

We weighed five things. Construction: triple-weave and sewn-in linings over foam backing, since Good Housekeeping's testing showed blackout labels spanning 85% to 99.9% and foam is the layer that fails first. Coverage: total pair width relative to your window, because panels need to run 2 to 2.5 times the opening to seal the sides. Durability: Wirecutter's long-term look put foam backing at two to three years and quality triple-weave past five, so washability and woven fabric mattered. Safety: OEKO-TEX Standard 100 certification, which fewer than 30% of budget panels carry and which we treat as near-mandatory for nurseries. Hanging: grommets, back tabs, rod pockets and pleats each behave differently, and the ones that pull fabric close to the wall block more light.

If you want a solid, dark-both-sides panel for a kid's room: The BGment Navy Blue Blackout Curtains for Bedroom ($13.99) — BGment's triple-layer polyester is the same color on both sides, which keeps the view from the street looking intentional. The listing is honest in a way we appreciate — it says up to 85% light blocking, not 100%, and owners generally describe it as plenty dark rather than pitch black. Six grommets per panel hang easily, the fabric is soft, and it's machine washable. The catch is size: the 42-by-63-inch pair is short and narrow, so it fits small or standard windows and nothing bigger. For a nursery with a modest window, that's fine. For a wide bedroom window, look at the top pick instead.

This is what our research surfaced, not a survey of everything sold. Blackout curtains are a crowded category with hundreds of near-identical listings, and the panels below all have real buyers who like them — they just lost to a pick on light blocking, coverage or construction.

The Eclipse Kendall Thermaback Blackout Curtain Set ($22.29) — The Eclipse Kendall Thermaback is the one you can grab off a shelf at Walmart or Target without waiting for shipping, and its Thermaback foam backing does block a lot of sun and heat. Owners in Florida report it holding up against summer light, and one kept a set going six years. But foam is the construction that Wirecutter's long-term look found cracks or peels within two to three years, the panels are only 42 inches wide each, and a meaningful share of owners say it darkens the room without fully blacking it out. The care instructions call for line drying, which is a real chore. Buy it if you need curtains today and a drive to the store beats a delivery window.

The Sun Zero Barrow Energy Efficient Rod Pocket ($17.99) — Sun Zero's Barrow panel is a rod-pocket curtain in nice colors at 54 inches wide each, which is generously wide for the category. Owners like the vintage blue and sage colorways and the price, and several use it in bathrooms and entryways where a little filtered light is welcome. That's the tell: owners describe this as room-darkening, not blackout, and note that light-colored versions can glow when the sun hits. The Amazon listing gives almost no construction detail — no fabric weight, no lining description. If you want good-looking drapes that take the edge off bright sun, this works. If you're trying to sleep at noon, it isn't the one.

The RYB HOME Grey Blackout Curtains for Kitchen ($12.56) — RYB HOME's grey panel is a triple-weave fabric with a 3-inch rod pocket, and it's genuinely useful for the windows most curtain guides ignore — bathrooms, kitchens, basements, RVs. At 42 by 45 inches it's a short panel by design. Owners praise the thickness and the privacy, and it does cut heat well. But the light blocking lands in the 85% to 99% range depending on color, and several owners specifically say it isn't blackout even though the listing says so. It also supports clip rings, which aren't included. For a small utility window, it's a smart buy. For a bedroom where you need dark, our picks do more.

Mounting matters more than fabric, and it's where most people lose. Hang your rod 6 to 12 inches above the window and extend it 4 to 6 inches past the frame on each side — Apartment Therapy's reader trials found that this alone measurably cut perceived morning light for day sleepers, versus mounting flush to the trim. Buy enough width that the closed panels total 2 to 2.5 times your window opening, so the fabric hangs in folds instead of stretching flat. For the last stubborn slivers of light, a wraparound rod that returns to the wall, a ceiling-mounted track, or a simple valance across the top will seal the gaps fabric can't. Wash on cold, gentle, and tumble dry low, then hang the panels immediately — creases set fast, and a hot dryer is what kills a lining.

For this guide:

• We compared manufacturer specifications for every panel here, including fabric construction, total pair width, hanging style and care instructions.
• We read published testing and reporting from the Good Housekeeping Institute, Bob Vila, Forbes Home, Wirecutter and Apartment Therapy, along with Department of Energy and sleep-research findings on light and insulation.
• We reviewed recurring themes in owner feedback, particularly the common gap between blackout claims and how dark rooms actually get.
• We read owner reviews on every listing, weighted toward the critical ones, because that is where the recurring failures show up.
• We have a systematic way of automatically fetching the latest prices, so the numbers on this page stay current.
• This is a research-focused guide, so the team may not own every product listed — though we often do own the top winners, which gives us extra context for the recommendations.
• We don't accept free products, and the retailer commission never changes which product we recommend.
