Curtain Length Guide: Where Should Curtains End?
Share
A panel that stops two inches above the floor looks like a mistake, even when nobody can say why. Hems matter. The gap between a room that feels finished and one that feels rented often comes down to where the fabric lands. So if you're asking how long should curtains be, the honest answer is that there are four lengths worth using, and one of them is right for your window.
At ARCADA we lean toward panels that reach the floor. Short curtains have their place, but they're the exception, not the default.
How long should curtains be? The four drop points
Start with the floor as your reference. Float is the shortest of the grown-up lengths: the hem sits about half an inch off the floor. It's practical. Nothing drags, nothing collects dust, and the panels slide cleanly when you open them each morning. Good for kids' rooms and anywhere you pull the curtains twice a day.
Kiss is where the fabric just grazes the floor, zero gap, no pooling. This is the tailored look most people want, and the hardest to nail, because your floor is probably not level. A half inch of variance across a wide window will show. Measure at several points.
Break lets the panel land and bend slightly, the way a well-hemmed trouser breaks over a shoe. Add one to two inches beyond the floor. It's forgiving. Uneven floors disappear and the look stays crisp without going fussy.
Puddle is the dramatic one: six to sixteen inches of extra fabric pooling on the floor. It reads romantic, a little old-world, and it's a commitment. Puddled curtains need straightening, they trap pet hair, and you won't want to open and close them often. Save them for a bedroom or a formal sitting room you don't walk through in muddy boots.
Measure from the rod, not the window
Here is where most people go wrong. They measure the window and forget the rod sits above it. Your finished length runs from the bottom of the curtain ring, or the top of the rod pocket, down to your chosen drop point. Not from the window frame.
Hang the rod first. We usually set it four to six inches above the window casing and wide, extending the rod six to ten inches past the frame on each side so the panels stack off the glass and the window looks larger. Then measure down. If you want the exact ring-to-floor method with worked numbers, our guide to measuring for curtains walks through it step by step.
One more thing on height. For that ceiling-tall effect, mount the rod close to the ceiling or crown molding rather than just above the frame. A room with an eight-foot ceiling suddenly feels taller. The panels have to be long enough to reach, though, so buy the length to match. Don't hang a rod at nine feet and expect a standard 84-inch panel to cover it.
Standard panel lengths, and when to size up
Ready-made panels come in a handful of drops: 63, 84, 96, 108, and 120 inches. Measure your ring-to-floor distance, then round up to the next size and hem the excess. An 84-inch panel suits a standard window with the rod hung a few inches above the frame. Go to 96 or 108 if you're mounting near the ceiling.
Fabric changes things too. Linen relaxes and drops a little after it hangs, so a panel that kisses the floor in week one may float by week three. If you're set on linen, and it's our favorite for the way it moves, read the linen curtains guide before you commit to a length. Heavier velvet holds its hem better but shows a poor measurement more plainly.
Cafe curtains are the one true exception. In a kitchen or bathroom where privacy matters more than drama, a panel covering the lower half of the window is the right call. Everywhere else, go long.
Frequently asked questions
How long should curtains be if my floor is uneven?
Choose the break length. One to two inches of extra fabric lets each panel settle onto the floor and hides the variance. The kiss look is unforgiving on out-of-level floors.
Should curtains touch the floor or hang above it?
For living rooms and bedrooms, touch the floor or break slightly. It looks intentional and tailored. Float them half an inch off the floor only in high-traffic spots or kids' rooms where you're opening them constantly.
Can I hem curtains that are too long?
Yes, and it's the smart way to buy. Order the next length up, then hem to your exact ring-to-floor measurement. Taking length off is easy. Adding it is not.
