For a bedroom that needs to be dark during the day, start with NICETOWN’s Thermal 100% Blackout curtains. They have a sewn-in black liner, two ways to hang, and the most size options in this list. If you want a linen look or have a thick rod, H.VERSAILTEX’s Faux Linen 100% Blackout panels fit rods up to 3 inches. For a sliding door or a wide window, Best Home Fashion’s Wide Width panel comes 80 or 100 inches wide, and if you’d rather keep your current curtains, Best Home Fashion’s blackout liners hang behind them.

The fabric is only half the job. Light leaks around the top, sides and middle of any curtain, so the measuring section below matters as much as the pick. Nobody at Sound Sleep Gear has hung these curtains or measured their light blocking; this list compares what each maker publishes.

Why darkness matters for sleep

The National Heart, Lung, and Blood Institute advises keeping the bedroom “quiet, cool, and dark,” and for people who sleep during the day it suggests removing light distractions, with light-blocking curtains as its example. If you’re not sure you need full blackout, our blackout vs room-darkening comparison covers the difference.

The picks

NICETOWN Thermal 100% Blackout: best for a fully dark bedroom

NICETOWN builds these panels with a thick blackout construction and a sewn-in black liner backing that it says blocks 100% of sunlight and UV rays. Each panel has both back tabs and a 2.7-inch rod pocket, and NICETOWN recommends rods no larger than 1.7 inches in diameter.

NICETOWN describes 52-inch-wide panels in 63, 84, 95 or 108 inch lengths, sold as a pair, and its size menu lists 17 sizes in all, from 37 to 70 inches wide and 45 to 108 inches long. For care, NICETOWN says to machine wash cold on a gentle cycle, tumble dry low or hang dry, and avoid high heat to protect the liner. The link below is the 52 x 63 inch pair in black; pick your own size on the listing.

H.VERSAILTEX Faux Linen 100% Blackout: best linen look and thick rods

H.VERSAILTEX pairs a linen-like polyester blend face with a 100% blackout white lining, which it says blocks all sunlight and UV rays. Each 52-inch-wide panel can hang three ways: back tab, rod pocket, or pleated with a hook belt. The 4-inch rod pockets take rods up to 3 inches thick, larger than the other picks here, and the hems are weighted.

Lengths are 63, 84 or 96 inches. The link below is the 52 x 84 inch pair in ivory.

Best Home Fashion Wide Width: best for sliding doors and wide windows

Standard-width panels, such as the 52-inch picks above, take several panels to cover a patio door. Best Home Fashion sells this single-layer, triple-weave panel 80 or 100 inches wide, in lengths from 84 to 108 inches, with antique bronze grommets that have a 1.6-inch opening. Its product page badges it “100% Light Blocked.” It is machine washable in cold water.

Best Home Fashion Blackout Liner: best for curtains you already own

If your current curtains suit the room but let light through, a liner hangs behind them. Best Home Fashion’s liners come as a pair of 35-inch-wide panels in lengths of 60, 80, 92, 104 or 120 inches. Best Home Fashion says they pair with existing curtains. Each has a rod pocket that fits rods up to 1 inch, the set includes hooks for installation, and the liners are removable and machine washable.

The maker doesn’t publish a light-blocking percentage for the liner, so treat it as an upgrade to your curtains rather than a full blackout guarantee.

How to measure for blackout curtains

NICETOWN publishes a step-by-step measuring guide. Its main numbers:

Step NICETOWN’s recommendation
Rod height 6 to 10 inches above the window frame
Rod width 6 to 15 inches beyond each side of the frame
Panel width About 1.5 times the rod width for blackout panels
Length Add 2 to 3 inches to your desired length for blackout
Header allowance Back tab or single rod pocket: add 1 inch; grommet: add 2 inches
Stack-back Open curtains take up about 15% to 25% of their width

So for a 100-inch rod, NICETOWN’s 1.5x guidance works out to two 75-inch panels or one 150-inch panel. Other makers’ numbers differ a little: Best Home Fashion suggests mounting 4 to 6 inches above the frame and 4 to 6 inches wider on each side for one of its blackout panels. Either way, the rod goes higher and wider than the glass.

Stopping light leaks

At the top. NICETOWN notes that a rod pocket helps reduce light leaks at the top of the window compared with ring-style curtains. Mounting the rod above the frame helps too.

At the sides. Extending the rod past the frame lets the panel cover the edge. Wraparound rods go further: Best Home Fashion says its wraparound rod lets blackout curtains be pulled all the way around to the wall (Search Amazon for Best Home Fashion uMIXm wraparound curtain rod ).

In the middle. Enough fullness lets the two panels overlap where they meet. A single wide panel avoids a center seam altogether.

At the bottom. NICETOWN’s extra 2 to 3 inches of length for blackout keeps the hem from leaving a gap above the sill or floor.

FAQ

How wide should blackout curtains be?

NICETOWN recommends about 1.5 times the rod width for blackout panels with grommet, back tab or rod pocket tops. For a 100-inch rod, that is one 150-inch panel or two 75-inch panels.

Do 100% blackout curtains make a room completely dark?

The fabric claim is the maker’s. Light still gets in around the top, the sides and the center seam, which is why makers recommend mounting the rod above and beyond the window frame and adding overlap.

Can I add blackout to curtains I already have?

Yes. Best Home Fashion says its blackout liners pair with existing curtains. They have a rod pocket, include hooks for installation, and come in lengths from 60 to 120 inches.
