The 5 Curtain Mistakes That Make a Room Look Unfinished

You've done the hard work. The furniture is good. The colours work. The art is up. And yet the room still feels like it's missing something — like it's almost finished but not quite. In our experience, the windows are usually where that feeling lives.

Here are the five curtain mistakes we see most often in Australian homes, and what to do instead.

1. Hanging Curtains Too Low

This is the single most common mistake, and the one with the most dramatic fix. When curtains are hung just above the window frame, they make the window feel like a hole in the wall rather than an architectural feature. The ceiling feels lower. The room feels smaller.

The fix: mount your track or rod as close to the ceiling or cornice as possible — ideally within 10–15cm. Suddenly, the ceiling feels higher, the window feels larger, and the whole room feels more considered. It costs nothing extra and changes everything.

2. Curtains That Don't Reach the Floor

Curtains that hover above the floor — not intentionally, just because they're slightly too short — look like a mistake. Because they are one. The gap between the curtain hem and the floor draws the eye in the wrong way.

The fix: always measure for floor-length curtains, and be precise. Your options are floating (1cm above the floor), touching (at floor level), or puddling (5–20cm of extra fabric). All three are intentional. Anything else isn't.

3. Curtains That Don't Cover the Window When Open

If your curtains, when open, still partially cover the glass, you're losing light and making your windows look smaller than they are. The curtain stack — the fabric when it's drawn back — needs to sit entirely off the glass.

The fix: extend your track or rod 15–25cm beyond the window frame on each side. This lets the curtains clear the glass completely when open, maximising light and view.

4. The Wrong Fullness Ratio

Fullness refers to how much fabric is used relative to the track width. Too little fabric and the curtains look thin and flat; they don't have the weight and volume that makes a window treatment feel luxurious. Too much and the folds become crowded and heavy.

The right ratio depends on the heading style. S-fold curtains typically use a 2:1 ratio (twice the fabric to track width). Pinch pleat curtains use 2.5:1 or higher. At Curtain Co. Studio, we calculate fullness for you — you just provide your measurements.

5. Choosing the Wrong Heading Style for the Room

Eyelet curtains have their place, but that place is rarely in a room that's meant to feel designed. The large metal rings can look heavy and domestic in a way that works against more refined interiors.

S-fold curtains give you clean, continuous waves that work in almost any contemporary or transitional interior. Gathered and pinch pleat styles bring structure and formality that suits classic spaces. The heading style sets the tone for the whole window — it's worth choosing carefully.

The Common Thread

Every mistake on this list comes down to the same thing: treating curtains as an afterthought. The rooms that feel most designed are the ones where the windows were considered with the same intention as everything else.

That's the standard we hold ourselves to at Curtain Co. Studio. And it's the standard your room deserves.
