How to Measure Wave Curtains?

Why precise measuring matters

Wave curtains are all about creating beautifully even folds that glide smoothly along a specialist track. To achieve that crisp, uniform wave effect, your measurements need to be accurate. Curtains that are too short can look unfinished, while ones that are too long or narrow may spoil the wave pattern. Careful measuring ensures your curtains hang perfectly and flow effortlessly.

Tools you’ll need before you begin

Have these essentials to hand:

  • A reliable metal tape measure (for accuracy)
  • A pencil to write down your figures
  • A notepad or sheet of paper for each window’s measurements
  • A step stool if your track is set high

Positioning the track

Wave curtains hang from a specially designed track, not a standard pole. You’ll be measuring from the track itself to your chosen finishing point, as this determines the drop. Always make sure the track is fitted or its position marked before you measure.

Step-by-step guide to measuring

Measuring the width

Measure the full width of the track from end to end. Don’t add extra for fullness – wave curtains are made to fit the track width exactly, with the fabric specially designed to create the wave effect.

Measuring the drop

Measure from the underside of the track (the glider channel) down to where you’d like the curtains to finish:

  • Above a sill: Stop 1–2cm above the sill.
  • Below a sill: Extend around 15cm below the sill.
  • To the floor: Finish 1–2cm above the floor for a clean look, or allow a few extra centimetres if you prefer the fabric to “pool” slightly.

Because wave curtains rely on precise folds, it’s important to measure carefully and consistently.

Double-check your numbers

With large drops and exact track fittings, even small errors can affect the finished look. Always follow the golden rule: measure twice, cut once.

Mistakes to avoid

Some common pitfalls include:

  • Measuring the window rather than the track width
  • Forgetting that the measurement should start from the underside of the track, not the ceiling
  • Estimating the drop instead of measuring precisely
  • Assuming fullness is needed – wave curtains are made to fit the track exactly
