Fifteen centimetres. That’s all it took. I’d only meant to lift the pole a touch to cover up the dust marks and the faded patch where the old bracket had sat for donkeys’ years, but when I stepped back into the doorway, the whole wall looked different, taller, calmer, somehow more finished, as if the room had been holding its breath and could finally exhale.
It turns out I’d stumbled onto something interior designers have known for ages and call the “high and wide” method. A trick for making a window look bigger is to hang your blind or curtains a little higher and wider than the edges of the window to give the illusion of it being larger. I hadn’t set out to make my window look bigger. I just wanted to hide a manky old fitting. But the effect was the same, and rather lovely.
Key takeaways
- A dusty curtain pole hiding attempt revealed a professional design trick most people overlook
- Your brain uses curtain placement as a visual cue—and moving it higher literally changes how tall your room feels
- The math is surprisingly simple, but most people get it wrong and lose up to 20% of their natural light
Why shifting the pole tricks the eye
Our brains are lazy in the nicest possible way. They take shortcuts, and one of those shortcuts is assuming that where the curtains start is where the wall “ends” and the window “begins”. Push that starting point up towards the ceiling and your eye follows, dragging the perceived height of the whole room with it. The placement of curtain rods can significantly influence how a room feels. When you install rods closer to the ceiling, it naturally draws the eye upward, making the room appear more open and your ceilings higher.
There’s a flip side, and it’s the mistake most of us make without realising. Rods hung just above the window frame can visually “shrink” a room, making it feel cramped. I’d lived with my curtains sitting practically on top of the window frame for six years and never once questioned it. That’s the thing about small domestic habits, isn’t it? We stop seeing them.
Getting the numbers right without a spirit level meltdown
You don’t need to guess, thankfully. For a standard living room or bedroom, for living and dining rooms, curtain rods should be installed about 10 to 15 centimeters (4-6″) above window frames, which happens to be almost exactly where mine ended up, purely by accident of trying to hide that grubby track. If you’re after something a bit grander, a good rule of thumb is to position the curtain rod about 30 centimeters (12″) above the window frame or halfway between the top of the window and the ceiling.
Width matters just as much as height, and it’s the bit people forget. Bring the pole out beyond the frame on each side rather than clamping it tight to the window, because the space between your window frame and the edge of the rod is called stack width, and it allows more light to fill the room, it makes the window look bigger, and it allows your curtains to hang neatly without being squished to the side. Skimp on this and you pay for it in daylight. Genuinely, a pole that’s too narrow can be a real problem: using a rod that’s too short can reduce your window’s openness by up to 20%, blocking both light and your view. That’s not a trifling amount, that’s a fifth of your natural light gone, just because the pole was an inch or two shy of where it should have been.
If you’re blessed with a properly tall gap between window and ceiling, don’t feel obliged to fill every inch of it. In most spaces, curtains can be hung six to 12 inches above the window for an expansive effect, and if there is more than 18 inches of space above the window, you can still hang curtains floor-to-ceiling by adding a valance at the top. Handy to know if you’re in one of those Victorian terraces with generous ceiling heights and a window that seems to have been fitted almost as an afterthought.
The length matters as much as the height
Here’s where I’ll be honest with you: lifting the pole is only half the job. If your curtains stayed the same length, you’ve now got a gap flapping about at the bottom, or worse, they’re hovering above the skirting board like they’re too posh to touch the floor. Hang panels long enough to either hover about an inch off the floor or puddle a few inches onto it. I ended up letting down a hem myself with a needle and thread on a Sunday afternoon, which cost me nothing but a cup of tea and a bit of patience, rather than buying a whole new set.
Colour and weight play their part too, particularly in older homes with lower ceilings to begin with. Many older homes were built with low ceilings, ostensibly because the lower the ceiling, the easier it was to keep a room warm, though today, with modern heating systems and effective insulation, low ceilings are seen much less often in new construction. If that’s your house, lean into lighter fabrics rather than heavy dark ones, because heavy, dark curtains absorb light and visually shrink a room, so if your goal is to make a room feel bigger, go lighter. Linen, cotton voile, soft neutral tones, they all do more heavy lifting than you’d expect for very little outlay.
A small job, a proper transformation
I want to be clear that I didn’t buy a single new thing to get this result. Same curtains, same pole, just repositioned brackets and two extra plugs filled in with a bit of filler where the old holes had been. That’s the whole beauty of it: a project you can finish with a drill, a tape measure, and perhaps a friend to hold the level steady while you mark the wall, rather than a trip to the shops.
One thing worth remembering before you reach for the drill: mark your new bracket positions with masking tape first and stand back to check them from across the room, ideally from the doorway, before committing to actual holes. The eye judges proportion far better from a distance than up close against the wall, which is exactly how I nearly missed just how much fifteen centimetres could do.
