Quick Answer: How to Measure Wavefold Curtains
Wavefold curtains, also known as S-Fold curtains, are measured using a structured track-based system, not window width alone.
Core formula:
Number of carriers × hook spacing = flat curtain width
System foundation:
Most Wavefold track systems use approximately 5–6 cm carrier spacing.
Hook spacing guide:
10 cm → Light Wave
12 cm → Standard Wave
14 cm → Deep Wave
Curtain drop is measured from the bottom of the track to the floor or desired finish point.

Key Measurement Rules
- Wavefold curtains are not measured by window width alone
- Track length is the starting measurement
- Carrier count affects wave rhythm and curtain structure
- Carrier spacing is the foundation of the Wavefold system
- Hook spacing determines the wave style
- Flat curtain width is calculated from carrier count and hook spacing
- Curtain drop is measured from the bottom of the track to the floor or desired finish point
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: Measure 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: Count the 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: Confirm Carrier Spacing
Most Wavefold track systems use:
Approximately 5–6 cm 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: Choose Wave Style and Hook Spacing
Hook spacing is typically selected between 10 cm and 14 cm for correct Wavefold formation.
- 10 cm → Light Wave — soft, minimal folds
- 12 cm → Standard Wave — balanced natural drape
- 14 cm → Deep Wave — full luxury finish
Hook spacing must always align with the carrier spacing system to ensure correct wave formation.
Step 5: Calculate Flat Curtain Width
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: Measure Curtain Drop
Curtain drop is measured from:
Bottom of the track → floor or desired finish point
To ensure proper installation, always allow a 5–10 mm 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, usually 5–6 cm
- 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.
Common Measurement Mistake
Many people measure window width and assume this determines the curtain size.
Correct method:
Use the track length, carrier count, carrier spacing, and hook spacing to calculate the flat curtain width.
