Step 1: Measure Your Windows

Accurate measurements are crucial for custom curtains. Please note:

• Measure twice, order once: Double-check all measurements before ordering
• Use a metal tape measure: Fabric tape measures can stretch and give inaccurate readings
• Measure in inches or centimeters: Be consistent with your units
• Round down: If between measurements, always round down to the nearest 1/4 inch
• Custom orders are final sale: Custom-made curtains cannot be returned unless defective

What You'll Need:

• Metal tape measure (at least 25 feet/8 meters)
• Step ladder or stool (for high windows)
• Pencil and paper to record measurements
• Helper (recommended for large windows)

How to Measure Width:

For Inside Mount (curtains inside window frame):

1. Measure the width of the window opening at the top, middle, and bottom
2. Use the narrowest measurement
3. Do NOT add extra width — we'll account for proper fit
4. Record this as your "finished width"

For Outside Mount (curtains outside window frame):

1. Measure the width of the area you want to cover
2. Add 4–8 inches (10–20 cm) on each side for better light blocking and privacy
3. Typical overhang: 8–16 inches (20–40 cm) total width beyond window frame
4. Record this as your "finished width"

How to Measure Length:

• Sill Length: Measure from rod to window sill, subtract 1/2 inch (1 cm)
• Apron Length: Measure from rod to bottom of window apron (trim), add 2–3 inches (5–8 cm)
• Floor Length: Measure from rod to floor, subtract 1/2 inch (1 cm) for clearance
• Puddle Length: Measure from rod to floor, add 2–6 inches (5–15 cm) for fabric pooling

Measuring Tips by Window Type:

Window Type	Measurement Tips
Standard Window	Measure width and length as described above
Bay Window	Measure each section separately, order individual panels
French Doors	Measure door glass area, add 2–4 inches on each side
Sliding Doors	Measure entire door width, add 6–12 inches each side
Arched Window	Measure rectangular portion only, contact us for arch solutions

Customization Tips & Best Practices

DO:

• Measure multiple times for accuracy
• Order fabric samples if unsure about color
• Consider fullness — order 1.5–2x window width for gathered look
• Account for rod placement above window
• Check ceiling height for floor-length curtains
• Order all panels for a room at once for color consistency

DON'T:

• Guess measurements — always measure
• Order without considering rod type and placement
• Forget to account for pattern repeats (if applicable)
• Order curtains too short — they can't be lengthened
• Mix different dye lots — order all panels together

Fullness Guide

Fullness refers to how much fabric is used relative to the window width. More fullness creates a more luxurious, gathered appearance.

Fullness Ratio	Description	Best For
1:1	Flat, minimal gathering	Modern, minimalist spaces
1.5:1	Light gathering, some folds	Casual, everyday look
2:1	Full, luxurious gathering	Traditional, elegant spaces (recommended)
2.5:1 or more	Very full, dramatic folds	Formal, luxury interiors

Example: For a 60" wide window with 2:1 fullness, order curtains with a total width of 120" (two 60" panels or four 30" panels).
