How to Weight a Curtain So It Hangs Straight? Guide

Why a curtain does not hang straight

A curtain that curls, ripples or pulls away from the wall at the bottom lacks weight. Light fabrics, sheers and freshly hung curtains tend to float: the top is held by the rod, but the bottom has nothing to pull it taut. Weighting solves this by adding weight in the bottom hem, which pulls the fabric towards the floor and makes it hang straight.

3 methods to weight a curtain

Sewn-in flat weights. Small flat weights, disc or square shaped, are sewn inside the hem, in each corner and at each vertical seam. They tension the fabric at the key points. It is the most discreet and durable method.

Weighted chain. A weighted chain, sold by the metre, slips into the whole bottom hem. It spreads the weight across the full width, ideal for sheers and very light fabrics that ripple.

Hem weighted at making. The most effective: a hem designed from manufacture with the right weight built in. No sewing to add, no visible weight, a straight drape from the moment you hang it. It is the custom solution.

Match the weighting to the fabric

The lighter the fabric, the more useful the weighting: a sheer or fine cotton needs a chain across the full width, where a heavy fabric already hangs straight under its own weight and needs at most weights in the corners. A thick, dense curtain generally needs no weighting: its weight is enough to keep it taut. Save the effort for fabrics that float.

Mistakes to avoid

Do not sew weights directly onto the visible fabric: always place them inside the hem, or they leave marks. Do not overload a light fabric with weights that are too heavy, which distort the hem instead of tensioning it. And before weighting, hang the curtain for 24 to 48 hours: some of the creases relax on their own under the fabric's weight, which may be enough without any weighting.

A straight drape from the start

The simplest weighting is the one you do not have to do. Kurtens makes custom curtains in a range of colors and fabrics, with a careful hem and the drape suited to the fabric, delivered ready to hang. To aim for the right length, essential for a crisp drape, see the measuring guide, then the Kurtens custom curtains.

Frequently asked questions

How do you make a curtain hang straight?

Weight the bottom of the hem with flat weights sewn into the corners and seams, or a weighted chain across the full width. The weight pulls the fabric towards the floor and removes the folds that curl up.

What is a weighted curtain chain?

It is a small weighted chain, sold by the metre, that slips into the bottom hem. It spreads the weight across the full width and suits sheers and light fabrics that ripple in particular.

Should you weight a thick curtain?

Generally no: a heavy, dense fabric already hangs straight under its own weight. Weighting is mainly useful on sheers and light fabrics that float. At most, a few weights in the corners are enough.

Where do you place the weights in a curtain?

Inside the bottom hem, in each corner and at each vertical seam. Never sew them onto the visible fabric, they would mark it. Hidden in the hem, they tension the curtain without showing.

Will a new curtain that curls relax on its own?

Partly: hang it for 24 to 48 hours, the fabric's weight relaxes some of the creases. If the bottom keeps floating after that, weighting the hem solves the problem for good.

A straight drape comes down to the length and the weight of the hem. Have your curtain made with a careful hem as a Kurtens custom curtain, delivered ready to hang.
