What Size Curtains for 9 Foot Ceilings?
For a 9 foot ceiling, buy 96 inch curtains. Hang the rod with its top about 98 1/2 inches off the floor if the panels hang from rings, or about 95 1/4 inches if they have grommets, and the hem floats half an inch above the floor. 108 inch panels only fit with the rod tucked under the ceiling, and then they touch the floor or puddle.

The wall is the reason. Framers build a 9 foot wall with 104 5/8 inch precut studs, which the Journal of Light Construction puts at about 109 1/4 inches of framing. After the ceiling drywall and the flooring go in, the room is close to 108 inches tall, and a 108 inch curtain plus its rings is taller than that.
Is 96 or 108 the right length for a 9 foot ceiling?
96 inches, for most 9 foot rooms. A 96 inch panel floats half an inch off the floor with the rod 11 to 15 inches above standard window trim, so you get the tall look with no fabric on the floor. Pick 108 only if you want the rod at the ceiling line and a hem that touches or puddles.
Two things decide it: how high the rod can go, and how far the curtain hangs below the top of the rod. Our guide on how to measure curtain rods puts the tall-look mount 2 to 3 inches below the ceiling or the crown molding, so on a 108 inch wall the rod tops out around 105 or 106 inches.
Then the heading changes the math. Parachute says rings and clips add 1 1/2 to 2 inches between the rod and the fabric. Grommets go the other way. Vermont Country Store sets its grommets about an inch below the top edge, so the fabric rises above the rod and the panel hangs about 1 1/4 inches shorter than its label.
Where to hang the rod for each curtain length
Work it backward from the panel. With rings, the top of the rod goes at the panel length plus 2 1/2 inches: 2 for the rings and half an inch of float. With grommets, it goes at the panel length minus 3/4 inch, since the grommet takes off 1 1/4 and the float adds back a half.
| Panel length | Rod top, rings or clips | Rod top, grommets | On a 9 ft ceiling |
|---|---|---|---|
| 84 in (213 cm) | 86 1/2 in | 83 1/4 in | Too short. The rod ends up at the trim |
| 95 in (241 cm) | 97 1/2 in | 94 1/4 in | Fits |
| 96 in (244 cm) | 98 1/2 in | 95 1/4 in | Fits. The standard pick |
| 98 in (249 cm) | 100 1/2 in | 97 1/4 in | Fits. IKEA's length |
| 108 in (274 cm) | 110 1/2 in | 107 1/4 in | The rod would sit at or above the ceiling |
| 120 in (305 cm) | 122 1/2 in | 119 1/4 in | No. More than a foot on the floor |
Now add a window. In most builder homes the tops of the windows and doors are set at 6 ft 8 in or 7 ft (80 or 84 inches), according to architect Jeff Pelletier of Board & Vellum, with the trim above that. Call the top of the trim 84 inches. Continental Window Fashions wants the rod at least 4 inches above the trim, so your rod can go anywhere from 88 inches up to about 105.
The 95, 96, and 98 inch panels all land inside that band, on rings or grommets. 108 doesn't. On rings it wants a rod above the ceiling, and with grommets it leaves no room for a bracket. Higher trim shrinks the band from the bottom and doesn't change the answer. The 98 inch row is IKEA's size: its MOALISA panels, for one, are 57 by 98 inches with an iron-on hemming strip in the pack.
Pick the panel first, then set the rod
Ready-made curtains come in a handful of lengths, and your wall comes in one. So choose the panel, then put the rod where that panel needs it. A 96 inch panel on rings puts the rod top at 98 1/2 inches, 14 1/2 above 84 inch trim. That's 60% of the way to the ceiling, close enough to The Shade Store's two-thirds rule that nobody will notice.
Before you drill, hang one ring on the rod and measure from the top of the rod to the bottom of the clip. Two inches is the top of Parachute's range, so if yours measure 1 1/2, drop the rod half an inch. Then measure floor to ceiling in three places. Our curtain length guide explains why: floors are rarely level, so you work to the shortest number.
Can you use 108 inch curtains with 9 foot ceilings?
Yes, if you want them long. Mount the rod 2 to 3 inches under the ceiling or the crown molding. 108 inch grommet panels then puddle about 1 to 2 inches onto the floor. Ring-top panels land 4 to 5 inches on the floor, past the 4 inch limit in our length guide, so hem those.
If the fabric you love only comes in 108, buy it and hem it. Taking a foot off a 108 inch panel is easy. Adding a foot to a 96 isn't. With crown molding, measure to the bottom edge of the crown, not the ceiling. A deep crown cuts into the rod's height, and then even 108 inch grommet panels need a hem.
Why some charts say 108 or 120 for a 9 foot room
Bob Vila's curtain length chart lists 108 inches to fall above the floor in a 9 foot room and 120 inches to rest on it. The math doesn't back that up. A 108 inch room can't float a 108 inch curtain, and a 120 inch panel leaves more than a foot of fabric on the floor even with the rod at the ceiling. The same article's rod advice for taller rooms, about a foot above the window, puts the rod near 96 inches over 84 inch trim. A 96 inch grommet panel hung there floats about an inch.
What size curtains for 8 foot and 10 foot ceilings?
For an 8 foot ceiling, buy 84 inch curtains with the rod a few inches above the trim, or 95 inch grommet panels with the rod near the ceiling. For a 10 foot ceiling, buy 108 inch curtains with the rod about two thirds of the way up, or 120 inch panels at the ceiling for a puddle.
Same assumptions as above: 84 inch trim, 2 inch rings, and half an inch of float.
| Ceiling | Rod partway up the wall | Rod right under the ceiling |
|---|---|---|
| 8 ft (96 in, 244 cm) | 84 in on rings, rod at 86 1/2 in | 95 in grommets float, 96 in touch the floor |
| 9 ft (108 in, 274 cm) | 96 in, rod at 95 1/4 to 98 1/2 in | 108 in grommets puddle 1 to 2 in |
| 10 ft (120 in, 305 cm) | 108 in, rod at 107 1/4 to 110 1/2 in | 120 in grommets puddle 1 to 2 in |
The 8 foot ceiling is the awkward one, with 12 inches of wall over 84 inch trim. An 84 inch panel on rings puts the rod 2 1/2 inches over the trim, short of Continental's 4 inch minimum, unless your trim tops out at 82 inches or lower. An 84 inch grommet panel would need its rod below the trim. Bob Vila's advice for 8 foot rooms is a rod nearly at the ceiling, which its chart pairs with a 96 inch panel. Our guide to what length curtains for 8 foot ceilings has the full rod math and three fixes for ring-top panels.
The 10 foot ceiling is the easy one. With 36 inches of wall above the trim, 108 inch panels fit on either heading. If your windows are taller, rerun the two formulas from your own trim height.
Sewing your own: what a 9 foot ceiling adds to the fabric
Made-to-measure curtains skip the size chart. The finished drop is the rod height minus the ring drop minus the float. With the rod two thirds of the way up a 9 foot wall (100 inches) on 2 inch rings, that's 97 1/2 inches.
On a 72 inch rod, the curtain fabric calculator turns that into 4 widths of 54 inch fabric (triple pinch pleat at 2.5x, 2 inch side hems, a 4 inch double hem), each cut 113 1/2 inches long, for 12.61 yards. The same window takes 11.72 yards under an 8 foot ceiling and 13.5 under a 10 foot one. That's about 0.9 of a yard per foot of ceiling.
A patterned fabric jumps instead. With a 27 inch repeat, each cut rounds up to 4 repeats (108 inches) at 8 feet but 5 repeats (135 inches) at both 9 and 10 feet. So it's 12 yards, then 15, then 15 again: 3 more yards to go from 8 to 9 feet, and nothing to go from 9 to 10. Pattern repeat explained shows how the rounding works.
