How Much Does It Cost to Blackout a Room? (2026 Prices)
Blacking out a typical two-window bedroom costs roughly $80 to $170 if you use window film or sealed blackout curtains — the two methods that reach genuine darkness rather than a polite dimness. As of August 2026, adhesive blackout film starts at $39.99 a roll, static-cling film at $43.99, and velcro-sealed blackout curtains at $42.99 per window. At the extremes, a DIY foil job costs under $20, and custom motorized shades are commonly quoted in the hundreds per window. Here is the whole market, method by method.
One disclosure before the numbers: the film and sealed-curtain prices in this guide are our own products. We only stock what we would use ourselves, and we name who should not buy each option further down.
Blackout costs by method (2026)
| Method | Price per window | Two-window bedroom | How dark? | Renter-safe? |
|---|---|---|---|---|
| Aluminum foil + painter's tape | About $5–$15 total | Under $15 | Near-total, looks terrible | Mostly — tape can pull paint |
| Adhesive blackout film (Tinta) | $39.99–$68.99 per roll | From $79.98 | Total, on the glass | No — the adhesive is permanent |
| Static-cling blackout film (Buio) | $43.99–$98.99 per roll | From $87.98 | Total, on the glass | Yes — no glue, no residue |
| Velcro-sealed blackout curtain (Notte) | $42.99–$82.99 per window | $85.98–$165.98 | Total, including the edge leaks | Yes — no drilling |
| Rod-hung blackout curtains | Commonly tens of dollars per panel, plus the rod | Varies | Dim — light halos at every edge | The rod usually needs drilling |
| Off-the-shelf blackout roller shades | Commonly listed from tens of dollars per window | Varies | Dark-ish — side gaps leak | Usually drilled into the frame |
| Custom or motorized blackout shades | Commonly quoted in the hundreds per window | Varies — budget accordingly | Very dark, with side channels | No — professional installation |
How much do blackout curtains cost?
Mass-market rod-hung "blackout" curtains are commonly listed at tens of dollars a pair, which sounds like the obvious answer until you hang a set. Two problems show up. First, plenty of curtains sold under the blackout label are actually dim-out fabric — hold one up to a sunny window and you will see the difference immediately. Second, and this is the one that matters: a rod holds fabric an inch or two off the wall, so daylight pours over the top and down both sides. You end up with a glowing picture frame around a dark rectangle, which is precisely the light that wakes you at 6am.
A sealed blackout curtain solves the frame problem instead of ignoring it. Notte mounts on velcro strips around the window perimeter — $42.99 to $82.99 per window depending on size — so the fabric seals edge-to-edge where rod-hung curtains leak. No drill, no rod, nothing a landlord will notice, and it folds flat for hotel rooms that believe in sunrise. Two windows run $85.98 to $165.98 depending on the sizes you need.
What does blackout window film cost per window?
Film is the cheapest route to total darkness on the glass itself. Our adhesive film Tinta runs $39.99–$68.99 per roll across ten sizes; our static-cling film Buio runs $43.99–$98.99. One roll typically covers one window — measure the glass, not the frame, before ordering. For a two-window bedroom that means from $79.98 with Tinta or from $87.98 with Buio, and either order clears the $75 mark for free US shipping.
Choosing between them is simple. Tinta bonds with adhesive and is meant to stay — media rooms, garage glazing, glass door panels, owned homes. Buio is static cling: no glue, lifts off clean, repositions and reuses, which is why it is the one we point renters toward. One honest caveat for both: film blacks out light coming through the glass. If your window also leaks around the frame, film alone leaves a thin bright outline — sealing the perimeter is a job for a velcro-mounted curtain, not another layer of film.
Are blackout curtains or blackout shades cheaper?
At the entry level they are commonly close — off-the-shelf roller shades and curtain pairs both start in the tens of dollars. Neither gets you to actual darkness out of the box: shades leave a light gap down each side where the roller sits inside the frame, and curtains leak around all four edges. The price jumps when you fix that with hardware. Custom and motorized blackout shades with side channels are commonly quoted in the hundreds per window before installation — the most polished road to a dark room and comfortably the most expensive. If cost per unit of darkness is your metric, film wins, a sealed curtain comes second, and custom shades are for people buying convenience and a remote control, not extra darkness.
What's the cheapest way to blackout a room?
Aluminum foil and painter's tape. About $5–$15 covers both windows, it blocks essentially all light, and it is the standard advice in every night-shift forum for a reason. The costs are non-monetary: it looks exactly like foil taped to a window, it crackles, and stronger tapes can pull paint or leave residue when you take it down.
Its real value is as a trial run. Research suggests a genuinely dark room supports your body's own melatonin production, and darkness is one of the few sleep variables you can test for pocket change. Foil the windows for a week. If you sleep noticeably better, you have your answer — upgrade to something you can live with. If nothing changes, you have saved yourself $80 to $170 chasing the wrong problem. Cardboard cut to the glass works the same way, minus the crinkle.
The two-window bedroom: budget, mid and premium
- Test run — under $20. Foil and tape. Ugly, effective, and the cheapest possible way to find out whether darkness is actually what your sleep is missing.
- Budget — about $80–$90. Two rolls of film: from $79.98 with Tinta if you own the place, from $87.98 with Buio if you rent. Total darkness on the glass, at the cost of daylight while it is up.
- Mid — about $90–$130. Mix and match: film on the window you never need daylight from, a mid-size Notte panel on the one with the leaky frame. This is the setup most day sleepers land on.
- Premium — about $170. Large-size Notte on both windows tops out at $165.98, sealed edge-to-edge, removable on inspection day. Beyond this you are in custom-shade territory — commonly hundreds per window — which buys motors and neat side channels rather than more darkness.
Who should not buy each of these
- Skip film if you use the room in daylight. Film is all-or-nothing while it is on the glass. Buio peels off and can be reused, but it is not a twice-a-day routine. If you want darkness at night and a view at breakfast, you want a curtain you can open.
- Skip Tinta if you rent. The adhesive is permanent by design. Buio does the same job on the glass and leaves without a trace.
- Skip Notte if ordinary dim is enough. If streetlight glow does not wake you, standard curtains are cheaper, softer-looking, and easier to throw open.
- Check before putting dark film on double-pane windows. Dark coverings can add heat stress on some sealed glass units — confirm your window type first.
Everything here except the foil ships tracked in the US (typically 7–14 days, after 1–2 business days of processing) and carries a 60-day money-back guarantee, so a method that does not survive contact with your bedroom can go back. The full range lives in our Blackout & Privacy collection.
