How to measure
- 01
Measure the actual working rod or track width; if hardware is not installed, record the window-frame width and your planned side extensions separately.
- 02
Measure the drop from the reference point stated for the selected heading—not from an unrelated edge of the window.
- 03
Check whether a package contains one panel or a pair, then compare total flat fabric width rather than the label width alone.
- 04
Recheck the selected product, tape, hooks, carriers, and fabric before ordering or cutting.
How to measure wave curtains
Finished coverage is tied to track, carrier, tape, and pocket-factor specifications Start with the actual rod or track and the heading reference named by the manufacturer.
How to use the fullness range
Multiply working coverage by an editable value between 1.6 and 2.5. Use the lower end for a lighter effect and the higher end only when the fabric and system support it.
Important limitation
Do not substitute a generic multiplier for the selected carrier and tape system; use the manufacturer chart.

Before you order or cut
Measure the actual window and selected product. Finished sizes, fullness, header take-up, hardware geometry, and manufacturer tolerances vary. Fabric can shrink, stretch, or behave differently by composition. Measurements do not guarantee fit, privacy, water containment, installation, load capacity, or structural safety. Use the selected product instructions, and have a professional workroom verify expensive custom-fabric orders.
