Quick answer

Two curtain-and-track sets (100 by 84 inches in black, 100 by 96 inches in cream) and one 9 foot aluminum track rated to 50 pounds. The cream set’s page says the bendable track can be shaped straight, curved, L-shaped or U-shaped. The aluminum track’s page says each 3 foot section links to the next, so you can build a longer run. If you want to go around a twin bed (38 by 74 inches), you need about 112 inches of track for an L, and the 108 inch section alone is short of that.

Room Divider Curtains Ceiling Mounted Track Sets, Black

The title lists one black blackout drape on a white bendable rail, W8.3 by H7 feet. The bullets say the three-layer polyester fabric gives sound insulation, heat insulation and 85 to 98 percent blackout, and that no other accessories are needed. The table gives 84 by 100 inches and a 2.29 kilogram package weight.

Room Divider Curtain Sets with Flexible Ceiling Track, Cream White

This set is 100 inches wide and 96 inches long. The bullets claim 100 percent blackout and describe an accordion-style curtain with wider pleats and smooth-rolling pulleys on a bendable track that can be straight, curved, L-shaped or U-shaped, with all hardware included.

FELIDESIGN Ceiling Curtain Track, 6 ft to 9 ft, White

A track without a curtain: aluminum, 108 inches long on the table, 2.4 pounds, with a stated 50 pound capacity, pre-drilled holes for ceiling mounting, wall brackets, roller hooks and a saw to cut it. Each 3 foot section connects to the next with built-in connectors.

Worked example: a track around a twin bed

This is our own arithmetic. A twin bed is 38 by 74 inches. A curtain that closes off the bed on two sides (one long side and the foot) runs 74 + 38 = 112 inches. A U that closes three sides runs 74 + 38 + 38 = 150 inches.

L around two sides112 in4 in shortOne more 3 ft section
U around three sides150 in42 in shortTwo more 3 ft sections

For fabric, a 100 inch curtain on a 112 inch run has to be pulled flat with no gathering, which looks tight. A fuller look would call for a curtain about 1.5 times the track (about 168 inches), so two panels. That ratio is a common styling rule, not something the pages state. For height, a ceiling of 96 inches matches the cream set’s 96 inch drop, while the black set’s 84 inch drop leaves 12 inches of gap above the floor on an 8 foot ceiling, which is a design choice for airflow and a loss of privacy at the bottom.

Choosing

If you want a kit, take a set and check the shape of your run. If you already have a curtain, take the track. For a rental with no ceiling screws, see bed separator ideas for the tension-rod option and room sliding door divider for door-width curtains.

Questions to ask the seller before you order

  1. How much curtain weight does each track hold, and is the 50 pound figure for the whole run?
  2. How many runners come in the set, and how many do I need for a 112 inch run?
  3. Can the track be cut to length and rejoined?
  4. Does it mount to a ceiling that is plaster, drywall or concrete, and what screws are included?
  5. Is the blackout claim a measured figure?

After it arrives

Find the ceiling joists before you mount. A 50 pound capacity on a track screwed into drywall alone is at the mercy of the anchors, so use screws into joists or the anchors the maker supplies. Bend the track gently on a flat floor before lifting, since a kink is hard to remove once it is on the ceiling. Run the curtain back and forth to test the glide before you hang it on a bed.

A second worked scenario: a curtain across a 10 foot room

This is our own arithmetic. A room is 10 feet (120 inches) wide and 8 feet (96 inches) high, and you want a curtain that crosses the whole room to hide a sleeping area.

ItemCalculationResult
Track lengthRoom width120 in
108 in trackOne 9 ft section12 in short
Section count120 / 363.3, so four 3 ft sections
Curtain width for 1.5 times fullness120 x 1.5180 in
100 in curtains needed180 / 1001.8, so two panels
Curtain dropCeiling 96 in96 in cream set fits; 84 in black set leaves 12 in

Two panels of the cream set (100 by 96 inches) would give 200 inches of fabric on a 120 inch track, a ratio of 1.67, which is fuller than the 1.5 target. The 108 inch aluminum track alone cannot span 120 inches, so you would need to add a section or order a longer length. The bendable track sets say nothing in the part we read about their length, so ask.

Reading the listings critically

The black set’s page calls itself a “sound-insulating” fabric and gives a blackout range of 85 to 98 percent, while the cream set claims 100 percent, so the claims are not on the same basis. The black set’s title mentions W8.3 by H7 feet, which is 100 by 84 inches, matching the table. The FELIDESIGN page gives a weight capacity (50 pounds), while the curtain-and-track sets do not. A curtain of heavy blackout fabric can weigh several pounds per panel, so a track rated at 50 pounds has margin for a long curtain; for a set without a rating, ask what the track holds.

Mounting and the ceiling

A track on the ceiling needs screws into something solid. If your ceiling is drywall, find the joists with a stud finder and fix the track into them. If the ceiling is concrete, you need masonry anchors and a drill. If it is a suspended tile ceiling, do not mount a loaded track on the tiles. A wall mount is an alternative: the FELIDESIGN page says the track comes with thickened wall brackets, so the same rail can run on a wall at the head of a bed.

A curtain against a screen

A curtain on a track takes no floor space and can be pulled open in seconds, which makes it a better fit for a studio where the bed needs to disappear. A screen can be moved to a different room and needs no tools. If you rent, check the lease about drilling. Our bed separator ideas guide shows the tension-rod alternative that needs no drilling.

Care

Blackout fabrics are often polyester with a coating, and some are labelled for machine washing at a low temperature while others are spot-clean only. The pages do not give care instructions in the parts we read, so check the label when it arrives. Hang the curtain for a day before use to let creases fall out.

Mistakes to avoid

Ordering curtain width equal to track length. The curtain will hang flat.

Forgetting the end stops. A curtain without them can slide off.

Using drywall anchors for a long run. Joists carry weight better.

Buying a curtain 84 inches long for a 96 inch ceiling and expecting privacy. There will be a gap.
