Wavefold curtains (also known as S-Fold curtains) use a structured track-based system that requires precise measurement. Unlike traditional curtains, Wavefold curtains are not based on window width alone. Instead, they rely on track design, carrier spacing, and hook spacing to create consistent, even waves across the entire curtain.
This guide explains the full step-by-step measurement process in a simple and practical way.
What Is a Wavefold Curtain System?
Wavefold curtains are designed to create smooth, continuous S-shaped waves using a specialised track system.
The system works through three key components:
- O-shaped carriers linked by a cord inside the track system
- Hooks that attach the curtain fabric to each carrier point
- Fabric that flows evenly between each wave position
This structure ensures a consistent wave pattern across the entire track.
Step 1 — Track Length
Start with your track length.
This is calculated as:
window width + returns on both sides
Returns are important because they:
- reduce light gaps
- allow curtains to stack neatly when open
Step 2 — Carriers
Next, count the number of carriers on your track.
Carriers are the fixed points where each hook attaches and define how the wave pattern is formed.
Carrier count affects wave rhythm, spacing consistency, and overall curtain structure.
In most Wavefold systems, even numbers of carriers are generally used to support balanced wave alignment across the track.
Step 3 — Carrier Spacing (System Foundation)
Most Wavefold track systems use:
approximately 5–6cm carrier spacing
This is the foundation of the Wavefold calculation system because it ensures consistent wave formation and even fabric distribution.
If carrier spacing differs from the standard system, hook spacing and fabric calculations must be adjusted accordingly.
Step 4 — Wave Style & Hook Spacing
Hook spacing is typically selected between 10cm and 14cm for correct Wavefold formation.
- 10cm → Light Wave (soft, minimal folds)
- 12cm → Standard Wave (balanced natural drape)
- 14cm → Deep Wave (full luxury finish)
Hook spacing must always align with the carrier spacing system to ensure correct wave formation.
Step 5 — Flat Curtain Width Calculation
The key formula is:
Flat curtain width = Number of carriers × Hook spacing
This gives the total fabric width before the curtain is formed into waves on the track.
Step 6 — Curtain Drop Measurement
Curtain drop is measured from:
Bottom of the track → floor or desired finish point
To ensure proper installation, always allow a 5–10mm gap between the track and curtain header.
This ensures:
- smooth operation
- correct hanging position
- clean visual finish
Key System Summary
Wavefold curtains are not measured by window width alone. They are a structured system built on:
- track length
- carrier spacing (5–6cm standard)
- carrier count
- hook spacing
- drop measurement
Each element works together to create a controlled and consistent wave pattern.

Why Wavefold Curtains Are Different
Wavefold systems offer more precision than traditional curtains because:
- fabric is calculated, not estimated
- wave spacing is system-controlled
- fullness is consistent
- installation is engineered for accuracy
This results in a more professional, architectural finish.
