Hang curtains so the ceiling looks higher, not the window
SaveThe ceiling looks higher the moment the rail moves up. Hang curtains close to the ceiling line and let the fabric fall to the floor, and the eye reads one tall column where it used to see a window sitting low in the wall. Fleur and Grey has gathered the placement decisions behind that change, the details that undo it, and the order to work in so the drill comes out once.
Starting with the rail height, not the fabric
The eye is lazy and easily fooled. It takes the highest horizontal line on a wall as the point where the room stops, then reads everything below that line as one shape. Fix the rail level with the window head and the line sits low, leaving a bare strip of wall above the window that reads as a separate, shorter space.
Move the rail up and the line travels with it. The same window now runs from the floor to just under the ceiling, and the strip of wall is absorbed into the column instead of cutting across it. Nothing in the room has changed except the position of one fixing, which is why the effect works in a rented flat as readily as in a house.
Fabric and colour come after. Position first, then tone, then the finish at the top.
Hanging curtains high enough to lift the ceiling
How high is high enough? As near the ceiling as the fixings allow, with the rail sitting above the window recess rather than level with the top of the frame. Keep the margin between rail and ceiling even at both ends, so it looks like a decision rather than a miscalculation.
Fixing to the ceiling rather than the wall
A ceiling-mounted rail gives the tallest reading available, because the fabric starts where the wall stops. It needs a fixing that reaches a joist or a sound ceiling anchor, and it earns its place in a room where the wall above the window is narrow or damaged. Allow for the drop of the mount itself when the curtain length is planned.
Leaving room for the bracket and the pleats
Every bracket takes a little height and every heading needs a little room to sit properly. Measure to the underside of the rail, then check that the top of the curtain clears the window frame once the fabric is gathered open. A rail pushed tight against the ceiling with the pleats crushed beneath it will look cramped, which is the opposite of the effect wanted.
The choice of position comes down to what the eye is allowed to read.
| Where the rail goes | What the eye reads | What to watch |
|---|---|---|
| Level with the window head | A window that stops where the frame stops | The wall above becomes a separate, shorter space |
| Above the window recess | A taller opening with a deliberate margin | Keep the margin even, since an uneven gap looks like an error |
| Just below the ceiling or cornice | A column running almost the full wall | Bracket drop and uneven ceilings |
| Fixed to the ceiling | The tallest reading the room can give | The fixing must reach something solid |
Running the fabric down to the floor
Height is decided at both ends of the curtain. A drop that finishes at the sill cuts the column short; a drop that reaches the floor completes it. Aim to finish just clear of the floor so the fabric hangs free, or let it touch where the room can take a little dust and the material is forgiving.
Long curtains also need generous widths. Skimped fabric pulls into a flat sheet when closed and loses the vertical fall that does the work.
- Finishing just clear of the floor, which keeps the fabric clean and the line crisp.
- Touching the floor, for a softer finish in a room with space to spare.
- Breaking slightly at the floor, where the fabric is light and the look is meant to be relaxed.
Once the drop is right, the seating below it has something to answer to, and our guide to arranging cushions on a sofa takes that layer from there.
Widening the run past the window frame
Width does as much as height. A rail that stops at the frame squeezes the window into a slot; carry it beyond the recess and the open curtains stacking over solid wall leaves the glass clear and the opening reading wider than the frame.
The overrun earns its keep in daylight as well. Fabric parked over the wall rather than over the glass is the difference between a bright room and a dim one, and it costs nothing beyond a longer rail.
Measure the drop and the overrun before ordering, because both are expensive to correct later. The method is set out in our guide to measuring for curtains.
Working through the curtain rail placement in order
Rail height, overrun and drop are settled together, so mark everything before anything is drilled. The sequence keeps each decision reversible until the last step.
- Hold the rail at the intended height and look at it from the doorway, not from underneath.
- Mark each bracket position in pencil, checking that the margin above the recess matches at both ends.
- Look at what sits behind the plaster, since a lintel, a pipe or a hollow patch changes the fixing.
- Offer the bracket up and confirm the rail clears any cornice, radiator or window furniture.
- Hang a single curtain, check the drop and the stacking, then fit the rest.
Choosing a colour and heading that make the room taller
Curtains close in tone to the wall blur the edges of the window and let the column run unbroken. Strong contrast does the reverse: it draws a frame around the fabric and stops the eye at the rail.
A heading is the way the top of a curtain is finished, and the options use different amounts of space. A gathered pleat hangs free beneath the rail, while a tab or eyelet top makes the rail part of the design.
Walls and curtains are read as one surface, so a colour chosen for the window tends to pull the rest of the room with it. Our piece on paint colours for small rooms covers the wall side of that pairing.
Checking the ceiling-height illusion before the drill comes out
Test the height with paper first. Tape a strip of lining paper at the proposed rail line and view it from the doorway, from a chair and from the hall. What looks generous at arm's length can look mean from across the room, and the reverse happens just as easily.
Light changes the reading. Check the strip in daylight and again with a lamp on, because a line that disappears in the evening may sit awkwardly by day. Follow the ceiling line where the ceiling is uneven rather than the window head, so the eye has one straight edge to trust.
Avoiding the details that flatten a room
A handful of habits undo the work, and each of them is easy to spot once the principle is clear.
- A rail level with the window head, which puts the hard line back where it started.
- Curtains that stop at the sill, cutting the column in half.
- A short rail that leaves the open fabric covering the glass.
- Heavy tiebacks pulling the fabric into a narrow waist.
- A pelmet crossing the wall at the window head rather than near the ceiling.
- Fabric so narrow that the closed curtain looks stretched.
None of this needs a bigger room or a bigger budget. It needs one fixing in the right place, a drop that reaches the floor and a run wide enough to hang properly. Get those right and the ceiling takes care of itself.

Frequently asked questions
If my ceiling is low but the window is tall, where should the rail go?
Start above the window recess, so the fabric keeps travelling towards the ceiling instead of stopping at the frame. Check the bracket clearance first, so the pleats are not crushed against the ceiling.
Does a higher rail really make a room feel taller, or does it only work with floor-length curtains?
The trick depends on the rail and the drop working together, because a high rail with short curtains gives the join away. Move both and the wall reads as one column.
Can I raise a curtain rail in a rented flat where drilling is not allowed?
A ceiling-fixed tension pole or a rail that uses existing fixings will lift the line without new holes. Read the tenancy agreement before fitting anything that grips the wall or ceiling.
