Should Curtains Touch the Floor? Float, Kiss or Puddle | Ona
Share
Updated October 2026 · By the Ona team · 7 min read
The short answer: usually, yes. Most curtains look best when the hem just touches the floor or floats about ½″ above it. Let them break or puddle on the floor in rooms where you rarely open them. Stop above the floor only when something is in the way, such as a radiator, heater, counter or window seat.
Key numbers: Ona's hem rule
- Float: ½″ above the floor. Panel length = drop − ½″.
- Kiss: the hem just touches the floor. Panel length = drop.
- Soft break: about 2″ rests on the floor. Panel length = drop + 2″.
- Puddle: about 4″ pools on the floor. Panel length = drop + 4″.
- Too short: 2″ or more above the floor.
Your drop is the distance from the top of the fabric to the floor. For the full method, read how long should curtains be. To skip the math, use the curtain calculator.
Float, kiss, break or puddle?
Four hem finishes cover almost every room. They differ by only a few inches, but each changes how a curtain looks, moves and meets the floor.
| Finish | Where the hem sits | Panel length | Gap under the hem | Upkeep | Best for |
|---|---|---|---|---|---|
| Float | ½″ (about 1 cm) above the floor | Drop − ½″ | ½″ | Easiest. Clears vacuums, pets and rugs. | Curtains you open daily, sliding doors, curtains behind furniture |
| Kiss | Just touches the floor | Drop | None | Easy | The default: a tailored, finished line |
| Soft break | About 2″ (5 cm) rests on the floor | Drop + 2″ | None | Straighten now and then | Bedrooms, relaxed rooms, floors that aren't level |
| Puddle | About 4″ (10 cm) pools on the floor | Drop + 4″ | None | Most. Collects dust; re-dress after each pull. | Formal rooms and curtains that mostly stay put |
Ona's size helper on each product page uses float (−½″), floor kiss (0″) and puddle (+4″). Our measuring guide adds a soft break (+2″).
Which one is right for you?
- You open and close them every day: float.
- You want the cleanest, most tailored line: kiss.
- You want a darker bedroom, or your floor isn't level: soft break.
- The room is formal and the curtains mostly stay closed or tied back: puddle.
How far should curtains be from the floor?
No more than ½″ above it for a floor-length look. Up to about 1″ still reads as intentional. At 2″ or more, curtains look as if they were bought too short.
| Hem position | How it reads |
|---|---|
| 4″ or more on the floor | Puddle: soft and formal, with the most upkeep |
| 1–2″ on the floor | Break: relaxed and forgiving |
| Touching the floor | Kiss: tailored |
| ¼–½″ above the floor | Float: clean and practical |
| About 1″ above the floor | Borderline. Acceptable on a sliding door or a sloping floor. |
| 2″ or more above the floor | Too short. Lower the rod or size up. |
| At the sill, or about 4″ below it | Sill or apron length: intentional, for windows with something below |
Measure to the finished floor: the top of the carpet, or the top of a rug that runs under the curtains. On deep carpet, a kiss sinks into the pile and looks like a break. A ½″ float above the pile often looks cleaner.
Should bedroom curtains touch the floor?
Yes. In most bedrooms, choose a kiss or a soft break. A hem that meets the floor leaves no gap at the bottom, which matters when you want the room dark.
A float leaves a ½″ strip open at the floor. That's fine in a guest room or a living space. In a bedroom you want dark, morning light can show along it.
For the darkest bedroom:
- Kiss the floor, or let about 2″ break.
- Hang the rod above and beyond both sides of the window, so the curtains cover more than the frame.
- Close the panels fully in the center.
Ona's grommet pair, wide panel and back-tab pair are lined, with supplier-listed 100% blackout fabric. Ona hasn't tested it, and light can still enter at the top, sides and center. The velvet pair is unlined and room-darkening, not blackout. Compare them in blackout curtains or bedroom curtains.
When a bedroom curtain shouldn't reach the floor: a radiator, dresser or bed sits right under the window. Use a float if the furniture stands clear of the hem, or sill length if it doesn't. In a nursery or kids' room, a float keeps the hem cleaner and out of the way of small feet.
Should living room curtains touch the floor?
Yes. Floor-length curtains hung high and wide make windows read taller and the ceiling feel higher. Float or kiss curtains you open every day. Puddle only those that are mostly for show.
- Windows you open every morning: float ½″, so the hem glides instead of dragging.
- Picture windows and formal rooms: kiss, or puddle about 4″.
- Behind a sofa: float. The sofa hides the hem, and the float keeps fabric from bunching behind the cushions.
- Sliding or patio doors: float. The panels slide and stack every day.
- Open-plan rooms: set every rod at one height and every hem on one line.
Dining rooms follow the same logic. They see little traffic, so a kiss or a puddle both work. Shop living room curtains.
When curtains shouldn't touch the floor
Floor length is the default, not a rule. Stop short when the floor is blocked or the fabric would get in the way.
| Room or window | Better length | Why |
|---|---|---|
| Over a radiator or heater | Sill or apron, stopping above the heater | Keeps fabric clear of the heat. See the next section. |
| Kitchen | Sill or apron | Clear of the stove, sink and counter |
| Bathroom | Sill or apron | Clear of water and damp floors |
| Window seat or built-in | Sill | Longer fabric would sit on the cushion |
| Window above a desk or counter | Sill | The surface would catch the hem |
| Floor vent under the window | Float, or sill length | A hem on the vent blocks the airflow |
Ona's shortest panels are 63″ and 72″. They can work as sill or apron length when your fabric-top-to-sill drop is close to one of them. Ona doesn't make café or tier curtains.
Should curtains touch the floor if there's a radiator?
Usually not. Choose a length that stops above the radiator, or floor-length curtains that stay open while the heat is on. Your heater's own instructions come first.
- Hot-water and steam radiators. Closed floor-length curtains sit in front of the radiator and hold its warmth between the fabric and the window. A sill- or apron-length curtain that ends above the radiator lets the heat into the room.
- Electric baseboard heaters. Check the label or manual for its curtain clearances. One baseboard heater maker's instructions we checked ask for at least 1″ between full-length drapes and the floor covering, and at least 2″ between the front of the heater and the nearest fold. For short drapes, they ask for at least 6″ above the top of the heater. A ½″ float or a puddle would not meet those numbers.
- Space heaters. US fire-safety guidance is to keep anything that can burn, curtains included, at least 3 feet from a space heater.
- Floor vents. Don't let a break or a puddle cover them.
Ona's curtains carry no flame-retardant claim. Keep all curtain fabric clear of heat sources.
Puddle curtains: how much, and when
Puddle curtains are panels long enough to pool on the floor. Ona's puddle is +4″: choose a panel about 4″ longer than your drop.
| Puddle | Extra length on the floor | Panel length | Look |
|---|---|---|---|
| Slight (a soft break) | About 2″ | Drop + 2″ | Relaxed and easy to live with |
| Classic (Ona's puddle) | About 4″ | Drop + 4″ | Soft and traditional |
| Generous | 6″ or more | Drop + 6″ or more | Dramatic and formal; the most upkeep |
How to measure for puddle curtains. Measure your drop, add 4″, then pick the nearest listed length. A fabric top at 92″ gives a 96″ panel a 4″ puddle. A fabric top at 104″ does the same for a 108″ panel.
How to dress a puddle.
- Hang the panels and let them settle for a day or two.
- Gather the extra fabric at the hem and tuck the hem edge slightly under.
- Fan the fabric into an even pool, the same size on every panel.
- Re-dress it after you open or close the curtains.
Skip the puddle if you open the curtains every day, you have pets or a robot vacuum, the curtains cover a door, or there's a heater or floor vent below. Soft, heavier fabrics pool more gracefully than stiff ones.
Should curtains touch the floor or the baseboard?
The floor. Floor-length curtains run past the baseboard and end at the floor, or within ½″ of it. A hem that stops at the top of the baseboard sits several inches above the floor and looks too short. The one exception is an electric baseboard heater, where the heater's clearances decide the length.
How to measure for curtains that touch the floor
You need a tape measure, a pencil and about ten minutes.
- Set the rod height. Put the rod up, or mark exactly where it will go. For a classic line, Ona's guide puts the rod about 4–6″ above the window frame.
- Mark the fabric top. The length starts here, not always at the rod. Grommets sit below the fabric top, so a little fabric rises above the rod. Back tabs hold the rod behind the panel, and a rod pocket encloses it.
- Measure to the finished floor in three places. Measure at the left, the center and the right. Floors are rarely level. Use the shortest reading. That is your drop.
- Apply the hem rule. Subtract ½″ to float. Keep the drop to kiss. Add about 2″ for a soft break or 4″ to puddle.
- Pick the nearest listed length. If you land between two lengths, move the rod slightly, or choose the longer length and let it break. The curtain calculator does steps 4 and 5 for you, along with the width.
Worked example. With the fabric top at 96½″, a 96″ panel floats ½″ above the floor. Lower the fabric top to 94″ and the same panel breaks 2″. At 92″, it puddles 4″.
Which curtain length reaches the floor?
Find the height of your fabric top in the table. The row tells you which length gives which finish.
| Ona length | Float: fabric top at | Kiss: fabric top at | Soft break: fabric top at | Puddle: fabric top at | Ona styles at this length |
|---|---|---|---|---|---|
| 84″ | 84½″ | 84″ | 82″ | 80″ | Grommet pair (42″ or 52″ wide), back-tab pair, velvet pair |
| 90″ | 90½″ | 90″ | 88″ | 86″ | All four styles, including the 70″ wide panel |
| 96″ | 96½″ | 96″ | 94″ | 92″ | All four styles |
| 108″ | 108½″ | 108″ | 106″ | 104″ | Grommet pair (52″ wide), wide panel, back-tab pair, velvet pair |
| 120″ | 120½″ | 120″ | 118″ | 116″ | Back-tab pair only |
Heights are measured from the floor. Lengths are per flat panel. Velvet colors vary by length: Dark Green, Dark Gray and Sage Green at 84″; Dark Gray and Sage Green at 90″ and 96″; Burgundy and Dark Gray at 108″.
Will 84-inch curtains touch the floor? Yes, when the fabric top sits 84″ above the floor. On a window frame that tops out at about 80″, common in US homes, that puts the fabric top about 4″ above the frame. Raise the fabric top above about 85″ and they start to look short. Choose 90″ or 96″ instead.
Will 96-inch curtains float under an 8 ft ceiling? No. A float needs the fabric top at 96½″, which is above a 96″ ceiling. With the fabric top just below the ceiling, a 96″ panel rests on the floor as a break.

Curtains too short or too long?
Most length problems can be fixed without new curtains.
Too short
- Lower the rod. An inch or two rarely shows. Keep it above the window frame.
- Size up. If the hem sits 2″ or more above the floor, the next listed length usually solves it.
Too long
- Raise the rod. Lift it until the hem floats or kisses. Brackets are easiest to move before the curtains go up.
- Let it rest. Up to about 2″ on the floor reads as a soft break. About 4″ reads as a puddle.
- Hem the panels. Lined and blackout panels are best hemmed by a tailor. Measure carefully before hemming. Returns are limited to damaged, defective or incorrect items; alteration-related damage is not covered.
To keep long curtains off the floor, raise the rod or hem them to a ½″ float. Tiebacks help at a door or window you open every day.
How Ona's curtains fit
- Sizes are flat, per panel. A pair is 2 panels; the wide panel is 1. Folds reduce the width a panel covers once it hangs.
- Lengths run from 63″ to 120″, depending on style. See the table above.
- Every product page has a size helper. Enter your drop and choose float (−½″), floor kiss (0″) or puddle (+4″).
- Lined: the grommet pair, wide panel and back-tab pair. The supplier lists their fabric as 100% blackout. Ona hasn't tested it, and light can still enter at the top, sides and center.
- Unlined: the velvet pair, which is room-darkening, not blackout.
- Headings: metal grommets on the grommet pair, wide panel and velvet pair. Hidden back tabs and a rod pocket on the back-tab pair.
- Not included: rods, hooks and rings. No custom sizes.
- Shipping and returns: ships to the US only, with free standard shipping shown at checkout. Returns are accepted for damaged, defective or incorrect items only.

Curtains and the floor: questions, answered
Do curtains have to touch the floor?
No. Floor length is the classic choice, not a rule. Sill or apron length is right over radiators, counters and window seats. If curtains do go long, they should reach the floor or float within ½″ of it.
Is it okay if curtains don't touch the floor?
Yes, if the gap is small. A ½″ float still reads as floor length and is easier to live with. A gap of 2″ or more looks like a sizing mistake, unless the curtains clearly stop at the sill.
Can curtains be 2 inches off the floor?
They can, but they will look short. Lower the rod about 1½″ for a ½″ float, or choose the next length up.
Should blackout curtains touch the floor?
Yes, for the darkest room. A kiss or a 2″ break leaves no gap under the hem. Light can still enter at the top, sides and center, so hang the rod high and wide as well.
Is it better to have curtains too long or too short?
Slightly too long. An extra inch or two rests on the floor as a soft break and looks intentional. Curtains that stop short look as if they shrank.
Are drapes supposed to touch the floor?
Usually, yes. The same rules apply to drapes and curtains: float, kiss, break or puddle. Formal drapes in dining rooms and living rooms often break or puddle.
Should sliding glass door curtains touch the floor?
Float them about ½″ above the floor. Door curtains slide and stack every day, and a clear hem won't drag across the threshold.
Should all curtains in a room be the same length?
Yes. Hang every rod in the room at the same height and choose one hem finish, so the hems form one line.
How we made this guide
Ona's hem rule comes from its measuring guide and the size helper on each product page: measure from the fabric top, then float (−½″), kiss (0″), soft break (+2″) or puddle (+4″). The gap guidance reflects common designer practice, which puts a float at 1″ or less. Fabric-top heights are our own arithmetic from those rules. Heater clearances come from a baseboard heater maker's installation instructions and US fire-safety guidance. Checked October 2026.
