How do you hang curtains the right way? Hang the curtain rod high and wide: about 4 to 6 in above the window frame (or two-thirds of the way up to the ceiling, or just below the ceiling or crown molding for a taller look), and extend it 8 to 12 in past the frame on each side. Choose curtain panels whose combined width is 1.5 to 2 times the rod width so they look full when closed, and a length that just touches the floor or floats about 1/2 in above it. Measure from the rod to the floor before you buy, and fix the brackets into studs or wall anchors.
This guide covers how high to hang curtains, how wide the rod and curtains should be, standard curtain lengths, how to measure, curtain header styles, step-by-step installation, and how to hang curtains on tricky windows.
Curtain Hanging Rules at a Glance
| Measurement | Rule of thumb |
|---|---|
| Curtain rod height | At least 4 to 6 in above the window frame; higher (up to just below the ceiling or crown molding) makes the window and ceiling look taller |
| Rod width | 8 to 12 in beyond the frame on each side, so open curtains don't block the glass |
| Curtain width (fullness) | Total panel width 1.5 to 2× the rod width; 2.5 to 3× for sheers |
| Curtain length | Touching the floor, or floating 1/2 in above it |
| Brackets | Into studs or rated wall anchors; add a center bracket on rods longer than about 5 ft |
How High to Hang Curtains
The most common mistake is hanging the rod right at the top of the window frame. Hanging it higher draws the eye up and makes the window, and the whole room, look taller.
- Minimum: 4 to 6 in above the top of the window frame.
- Designer rule: about two-thirds of the way between the top of the frame and the ceiling.
- High and dramatic: just below the ceiling or crown molding, about 1 to 2 in down. This works especially well with 8 ft ceilings and small windows.
Keep all curtain rods in a room at the same height, even if the windows are different sizes, so the room looks consistent. Make sure your curtain length matches the rod height you choose: the higher the rod, the longer the curtains need to be.
How Wide Should Curtains Be?
Rod width
Extend the curtain rod 8 to 12 in beyond the window frame on each side. When the curtains are open, the panels stack on the wall instead of covering the glass, so you get more natural light and the window looks wider. For heavy, lined curtains that stack thickly, go to 12 in or more.
Curtain fullness
Curtains look best with soft folds when closed, which takes more fabric than the width of the window. Multiply the rod width (not including finials) by 1.5 to 2 for standard curtains, and by 2.5 to 3 for sheers. Example: a 72 in rod needs 108 to 144 in of total panel width, so two 54 in panels give a tailored look, or two 72 in panels a fuller look.
Standard Curtain Lengths and How Long Curtains Should Be
| Standard curtain length | Typical use |
|---|---|
| 63 in | Windows above furniture, short windows, sill or apron length |
| 84 in | Standard length for 8 ft ceilings with the rod a few inches above the frame |
| 95 to 96 in | 8 ft ceilings with the rod hung high; the most versatile length |
| 108 in | 9 ft ceilings or rods mounted close to the ceiling |
| 120 in and longer | 10 ft ceilings, tall windows and two-story rooms |
Curtain length styles
- Float: 1/2 in above the floor. Clean, modern, easy to vacuum, and good for curtains you open and close daily.
- Kiss: just touching the floor. Tailored and polished, but requires precise measuring.
- Break: 1 to 3 in extra so the fabric bends slightly on the floor. Relaxed and forgiving.
- Puddle: 6 to 8 in extra pooling on the floor. Romantic and formal, but collects dust; best for curtains you rarely move.
- Sill or apron length: to the windowsill or just below the frame. Use only where long curtains won't work, such as above a radiator, a kitchen counter or a built-in bench.
Avoid curtains that stop a few inches above the floor ("high-water" curtains); they make ceilings look lower.
How to Measure for Curtains
- Decide the rod height and mark it on the wall in pencil.
- Measure the rod width: the window frame width plus 8 to 12 in on each side.
- Measure the length from the rod down to the floor. If you use rings or clips, measure from the bottom of the ring, where the curtain will hang. For grommet curtains, measure from the top of the rod.
- Choose a standard length closest to your measurement, then hem or adjust the rod height slightly to fine-tune.
- Calculate panel width using the fullness rule above.
Curtain Header Styles
| Header | Look | Best for |
|---|---|---|
| Rod pocket | Gathered, casual | Curtains you rarely open; sheers |
| Grommet | Modern, deep even folds | Curtains you open and close daily |
| Back tab or tab top | Tailored pleats or relaxed loops | Living rooms, bedrooms |
| Pinch pleat | Formal, structured | Traditional rooms; hung with rings or hooks |
| Ripplefold | Soft, even S-shaped waves | Modern rooms and track systems |
| Ring clips | Turns any flat panel into a pleated look | Adjusting length; easy opening |
How to Hang Curtains: Step by Step
You'll need: a tape measure, pencil, level, drill, stud finder, wall anchors (if not drilling into studs), a curtain rod with brackets, and curtains.
- Mark the bracket positions. Measure up from the frame to your rod height, and out from the frame 8 to 12 in on each side. Use a level to make sure both marks are at the same height.
- Find studs or use anchors. Use a stud finder; above most windows there's a solid header you can screw into. Otherwise, use drywall anchors rated for the weight of the rod and curtains.
- Install the brackets. Drill pilot holes, insert anchors if needed, and screw the brackets in. For rods longer than about 5 ft, add a center bracket so the rod doesn't sag.
- Hang the curtains on the rod, then set the rod in the brackets and tighten the set screws.
- Check the length and adjust the rod height or hem if needed.
- Train the folds. Steam out the packing creases, arrange the pleats evenly, and tie the curtains loosely in place for a day or two so the folds set.
Layering Curtains: Sheers and Drapes
For privacy by day and darkness at night, use a double curtain rod: sheers on the inner rod, close to the window, and heavier drapes or blackout curtains on the outer rod. The sheers soften natural light without blocking it; the drapes add warmth, insulation and privacy. Hang both at the same height and length for a clean look.
How to Hang Curtains on Tricky Windows
- Sliding glass doors: extend the rod at least 12 in on each side so the curtains stack clear of the door, and use a single panel that draws to one side if the door slides one way.
- Bay windows: use a bendable bay window rod or separate rods on each section, with matching heights.
- Corner windows: use corner connectors or two rods meeting at the corner.
- Short or small windows: hang the rod high and wide and use floor-length curtains to make the window look larger.
- Windows close to the ceiling: use ceiling-mounted brackets or a ceiling track.
- Behind a sofa or bed: floor-length curtains can still work; float them just above the floor so the furniture doesn't crush the fabric. Keep at least a few inches between the curtains and a radiator or heat vent.
- Renters: tension rods, adhesive hooks or no-drill brackets that fit over the window frame avoid holes in the wall.
How to Hang Curtains: FAQ
How high should curtains be hung?
At least 4 to 6 in above the window frame; ideally two-thirds of the way up to the ceiling or just below the ceiling or crown molding.
How wide should a curtain rod be?
About 16 to 24 in wider than the window frame: 8 to 12 in on each side.
Should curtains touch the floor?
Ideally yes, or float about 1/2 in above it. Curtains that stop well short of the floor make a room look smaller.
What length curtains for an 8 ft ceiling?
Usually 84 in if the rod is just above the window, or 95 to 96 in if the rod is mounted high, near the ceiling.
How many curtain panels do I need?
Enough that their combined width is 1.5 to 2 times the rod width. Most windows need two panels; wide windows may need four.
How far should curtains extend past the window?
8 to 12 in on each side, so the open curtains don't cover the glass.
Do curtains need a center support?
Yes, on rods longer than about 5 ft or with heavy curtains, add a center bracket to stop the rod from sagging.
Hanging curtains well comes down to three numbers: rod height (high), rod width (8 to 12 in past the frame) and curtain length (to the floor). Measure carefully, buy panels with enough fullness, and the window will look larger and the room taller.
