Wave curtains are admired for their soft, uniform folds and contemporary look. However, if they’re too long, the elegant waves can collapse or drag on the floor, losing their signature rhythm. Shortening them helps maintain those smooth, symmetrical folds and gives your room a crisp, balanced finish.
Before you start
Unlike traditional curtains, wave curtains rely on specialist heading tape and gliders that create evenly spaced folds. Adjusting their length requires careful measuring to preserve that perfect wave effect. Begin by hanging the curtains on the track to determine the correct drop, marking where you’d like them to end — ideally 1–2 cm above the floor or windowsill.
Because wave systems need precise spacing and alignment, it’s often safest to have alterations handled by experts such as Wave curtains with fitting service who can ensure both the fold depth and hemline stay perfectly even.

Step-by-step guide to shortening wave curtains
- Hang and measure accurately: With the curtains on their track, mark the desired new length using tailor’s chalk or fabric pins.
- Remove the curtains and lay them flat: Detach them carefully from the gliders, laying each panel on a large, clean surface.
- Measure and cut: From your markings, measure evenly across the width of the fabric, allowing an extra 8–10 cm for a double-folded hem. Cut neatly along your marked line.
- Fold and press the hem: Create a clean double fold to hide the raw edge, pressing with an iron to flatten it.
- Secure the new hem: Sew along the folded edge or use professional hemming tape if you prefer a no-stitch option.
- Rehang and check alignment: Once reattached to the gliders, ensure each panel sits at the same height and that the waves fall naturally without tension.
Common issues and troubleshooting
If the waves look uneven after rehanging, it could be that one panel was shortened slightly more than the other — recheck your measurements from the top of the heading tape, not just the fabric. For lined curtains, remember to adjust both layers together to prevent puckering.
If you notice the folds pulling too tightly or hanging unevenly, experts offering Wave curtains with fitting service can realign and adjust the heading tape spacing to restore a perfectly fluid look.

Wave curtains depend heavily on symmetry and precise measurements. If your fabric is patterned, lined, or made from a delicate material like voile, even a small error can disrupt the wave spacing.
