Measurement Guide for Hook-Style Curtains on Installed Rod or Track
1.Hook Curtain Measurement for Installed Rod or Track
- Width (W)
Measure the net length of the installed Roman rod or track (excluding decorative ends).
This size is the basic reference value for calculating the finished curtain width.
Tip: Round to the nearest centimeter (or ½ inch) when measuring width. - Height (L1 / L2)
Measure from the hook connection point (i.e. the bottom of the Roman rod ring or the bottom of the track slider) to the desired drop position. -
L1 — Sill Height:
Measure to just below the window sill
▸ Suitable for installations that only cover the window without reaching the floor -
L2 — Floor Height:
Measure to the floor
▸ It is recommended to subtract 1–2 cm (≈ ⅜ to ¾ inch) from the measured height to avoid dragging and to ensure the curtain drapes naturally and neatly
2. Grommet (Eyelet) Curtain Measurement Guide
- Width (W)
Measure the net length of the installed curtain rod (excluding decorative finials).
This measurement is used as the base width to calculate the finished curtain size.
Tip: Round to the nearest centimeter (or approximately ½ inch) for accuracy. - Height (L1 / L2)
Measure from the top of the curtain rod to your desired drop point.
Since grommet (eyelet) curtains hang through rings over the rod, the curtain body naturally drops 3–4 cm (≈ 1¼–1½ inches) lower than the top of the rod.
So, always start your measurement from the top of the rod. -
L1 – Sill Length
Measure from the top of the rod to just below the window sill
▸ Suitable for non-floor-length curtains - L2 – Full Length
Measure from the top of the rod to the floor
▸ Recommended finished height = rod-to-floor measurement minus 1–2 cm (≈ ⅜–¾ inch) to avoid dragging and ensure a neat look

FAQS
Do I need to round my measurements?
Yes. Please round the width to the nearest whole centimeter (or ½ inch) for accurate fullness calculation. Height should be measured as precisely as possible.
Should I measure each window separately?
Absolutely. Even similar-sized windows can vary slightly. Always measure each window or door individually for the best fit.
What fullness ratio should I choose?
It depends on your desired look:
-
1.8x – 2.0x for a soft, relaxed drape
-
2.2x – 2.5x for a balanced, full appearance
-
3x for a rich and luxurious effect
📌 Note: For heat-setting pleat finishing, we only support 2.2x and above to ensure long-lasting shape and structure.
Where should I start measuring the curtain height?
It depends on the curtain heading style:
-
For hook styles: measure from the bottom of the track or hook ring
-
For grommet or rod-pocket styles: measure from the top of the rod
If using rings, include ring height in the measurement.
Should I install the curtain rod before measuring?
We recommend installing the rod or track first. This ensures accurate height measurement based on actual mounting position, especially for ceiling or wall mounts.
Measurement Guide & Helpful Reminders
Your curtains will be custom-made based on the width and height you provide. Please ensure your measurements are accurate.
All hook-style headers (including single pleat, triple pleat, tailor pleat, hidden pleat, etc.) will come with adjustable pin hooks.
Curtain rings or clip rings are not included and must be purchased separately if needed.
We recommend using a steel measuring tape and rounding measurements to the nearest centimeter, especially for width.
Each window or doorway should be measured individually to avoid size discrepancies.
Preferences for curtain fullness may vary—some prefer a light and relaxed drape, while others may want a richer, more gathered look.
Please select your desired fullness ratio based on your interior style and aesthetic preference.
