Floor to Ceiling Curtains: Why the Drop Is Everything

Of all the decisions you make when ordering curtains, the drop is the one that has the most visible impact. It determines how tall your windows feel, how high your ceilings appear, and whether your curtains look considered or accidental. It's also the measurement most people get wrong.

Here's everything you need to know about curtain drop — and why floor to ceiling is almost always the right answer.

What Is Curtain Drop?

Curtain drop is the measurement from the top of your track or rod to wherever the curtain finishes. It's one of two key measurements you provide when ordering custom curtains (the other is track width).

The drop determines whether your curtains feel luxurious or lacking — and it's more forgiving to measure than most people expect.

Why Floor-to-Ceiling Is the Designer Default

Interior designers almost universally specify floor-to-ceiling curtains — and it's not because they're extravagant. It's because curtains that run the full height of a room do several things simultaneously:

• They make the ceiling feel higher than it is
• They make the windows feel larger than they are
• They give the room a sense of scale and proportion
• They create a strong vertical line that anchors the wall

A curtain that stops at the window sill, or even one that stops at the bottom of the window frame, does none of these things. It makes the window look like an opening in a wall rather than a feature of the room.

Your Drop Options

When ordering floor-length curtains, you have three choices for how the fabric meets the floor:

Floating (1cm above the floor)

The curtain hem sits just clear of the floor — close enough to look intentional, high enough to make cleaning underneath easy. This is the most practical option and suits contemporary, minimal interiors well.

Touching (at floor level)

The hem sits exactly at floor level. This is the most common specification and looks clean and tailored in most settings. It requires accurate measuring but isn't difficult to achieve.

Puddling (5–20cm extra)

Extra fabric is allowed to pool on the floor, creating a relaxed, luxurious effect. This works best in formal spaces — a bedroom or dining room — with heavier fabrics. It's a strong aesthetic choice that's very much back in fashion in considered interiors.

The Rule About Track Height

The other half of the floor-to-ceiling equation is where you mount your track. For curtains to run from ceiling to floor, the track needs to sit close to the ceiling — ideally within 10–15cm of the cornice or ceiling line.

Many people mount their tracks just above the window frame out of habit. Moving the track up, even by 20 or 30cm, changes the character of the room dramatically. It's one of the highest-impact, lowest-cost changes you can make to a space.

What About Windows That Don't Reach the Floor?

This is the question we get most often, and the answer is straightforward: hang floor-to-ceiling curtains anyway.

A curtain that starts at the ceiling and runs to the floor makes the window look taller and the room feel larger, regardless of where the window itself finishes. The curtain and the window are separate things. Let the curtain do what curtains do best — define the space, not just cover the glass.

The Bottom Line

Measure from the top of your track (or where your track will be, if it's not installed yet) to the floor. That's your drop. Add the appropriate amount for your chosen finish — minus 1cm for floating, at floor level for touching, plus 5–20cm for puddling — and you have everything you need.

It's the measurement that makes the most difference. It's also the one that's easiest to get right when you know what you're aiming for.
