Curtain Measurement Guide

Easy to follow! Measure your curtains step by step, avoid common pitfalls, and ensure a precise fit — beautiful and practical.

Step 1: Choose Your Curtain Header Style

First, decide which curtain header style you want. Different styles have slightly different measuring methods. Here are 3 popular options:

Soft Header

No fixed pleats at the top — simple, versatile, and suits most home decor styles. Compatible with 6 hanging methods: 4-in-1, hook tape, flat hook, tie-top, rod pocket, and back tab.

Important: When measuring width, always account for fabric fullness — otherwise, the curtains will look flat and unattractive.

Pleated Header

Neat, structured pleats at the top for an elegant, high-end look. Ideal for living rooms and bedrooms where you want to elevate the space.

Suitable styles: Pinch pleat, tailor's pleat, goblet pleat, box pleat, cartridge pleat, triple pleat, wave pleat, cylindrical goblet pleat.

Note: Only fits straight curtain rods; for curved/track rods, contact customer service for size recommendations.

Grommet / Eyelet Header

Circular grommets at the top for quick and easy installation. Slides smoothly on the rod with a clean, modern look suitable for most homes.

Features: Hangs beautifully with natural drape, holds its shape well, and is easy to maintain.

Pleated Header Curtain — Measuring Guide (Detailed Steps)

The key advantage of pleated curtains is their built-in fullness. The manufacturer pre-pleats the fabric, so you only need to measure the rod and drop length accurately — no need to calculate fullness yourself.

Step 1: Measure Curtain Rod Width & Mounting Position

Two scenarios: "rod already installed" and "rod not yet installed". Follow accordingly:

• Rod already installed: Use a steel tape measure to measure the distance between the inside edges of the rod finials, excluding the finials themselves (finials are decorative and not part of the usable width).
• Rod not yet installed: Plan the mounting position first. Determine "height" and "width extension" following these standards:
  • Height above window frame: Mount the rod 15–25 cm above the window frame (20 cm recommended for beginners). This visually raises the window and makes the room feel more spacious. Mark the position carefully to avoid installation errors.
  • Width extension beyond frame: Extend the rod 15–38 cm beyond each side of the window frame (15–25 cm for narrow windows, 25–38 cm for wide windows). This ensures curtains don't block the window when open and prevent light leaks.

Step 2: Understand Standard Fabric Fullness (No Calculation Needed)

The manufacturer already accounts for pleat fullness during production, so you don't need to worry about flat-looking curtains. Here are our standard fullness specifications:

• Pinch pleat, tailor's pleat, box pleat, goblet pleat: 1.6× fullness (for a 100 cm rod, the manufacturer uses 160 cm of fabric);
• Triple pleat, triple tailor's pleat: 2× fullness (for a 100 cm rod, the manufacturer uses 200 cm of fabric).

Key point: Just provide the curtain rod length — the manufacturer will automatically account for fullness. No need to add extra width!

Step 3: Determine Curtain Width & Length (Core Step)

The width you provide to the manufacturer is the fully extended width of one panel (including pleats). Key points:

• Width: The measurement from the first pleat on the left to the last pleat on the right when the curtain is fully extended — not the gathered width;
• Length: The vertical distance from the top of the curtain (top of pleats) to the bottom hem, measured at your desired drop;
• Gathered effect: When gathered, the width is approximately 15%–20% of the ordered width (e.g., a 127 cm panel gathers to about 20–25 cm), saving space;
• Note: Pleats are sewn in by the manufacturer and cannot be adjusted later — measure carefully.

Soft Header & Grommet Curtain — Measuring Guide (Detailed Steps)

The measuring logic for soft header and grommet curtains is essentially the same. The key difference is that you need to calculate fabric fullness yourself — default fullness is 100% (no pleats). For home use, 160%–200% is recommended for a better drape.

Simple guide: 160% (moderate gather, neat look), 200% (standard gather, full and elegant). Beginners, go with 200% — you can't go wrong!

• 1.6× rod length: Moderate gather, suitable for small windows and minimalist decor;
• 2× rod length: Standard gather, ideal for most homes with the best drape.

Soft Header — Measuring Details

Core concept: "Calculate total width based on fullness, then divide into panels." Beginners can follow the example directly. Key points:

• Length: Vertical distance from the top edge of the soft header to the bottom hem. Measure at your desired drop;
• Rod compatibility: Soft header with back tab only fits rods up to 4 cm in diameter — check before purchasing;
• Fullness: 200% recommended for natural-looking folds;
• Gathered effect: When gathered, width is approx 15%–20% of ordered width — space-saving and doesn't block the window.

Grommet / Eyelet — Measuring Details

The measuring method is the same as soft header. Pay special attention to "grommet inner diameter" and "length measurement". Key points:

• Length: Vertical distance from the top edge of the grommet to the bottom hem. Make sure the tape measure is perfectly vertical;
• Grommet size: Default inner diameter 4 cm, compatible with most standard curtain rods — no special instructions needed;
• Fullness: 200% recommended for best drape and smooth sliding;
• Gathered effect: When gathered, width is approx 15%–20% of ordered width — elegant and space-saving.

Quick Formula: Calculate Curtain Width Instantly

Can't remember all the steps? Just use these 3 formulas to instantly calculate your single-panel width — beginner-friendly!

Example: Single-width curtain (1 panel), rod length 200 cm → Pleated: 200÷1 = 200 cm; Soft header: (200×2)÷1 = 400 cm.

Step 2: Determine Curtain Drop Length for Perfect Drape

Different drop lengths create different visual effects. Measure from the top mounting point (pleat top for pleated; top edge for soft header/grommet) to the desired hem position.

Diagram: Left to right — "Floating (2-3 cm above floor)", "Kissing floor", "Pooling (5-10 cm on floor)"

3 recommended drop lengths — beginners can pick directly:

• Floating 2–3 cm above floor (Recommended): Most practical — doesn't drag on the floor, collects less dust, easy to clean. Works for 90%+ of homes.
• Kissing the floor: Just touches the floor for a clean, tailored look. Ideal for modern decor. Measure precisely to avoid uneven floor issues.
• Pooling 5–10 cm on floor: Ideal for luxurious/classic decor. Best drape. Suitable for rooms with infrequent window opening and no pets.

Beginner Tips — Measurement Pitfalls to Avoid

• Measuring tool: Always use a steel tape measure (cloth tape stretches and causes errors). Measure to the nearest cm — custom curtains are made exactly to your provided dimensions.
• Adjustment benefit: French pleat, triple French pleat, tailor's pleat and similar styles come with adjustable hooks and rings, allowing fine height adjustment during installation. Minor measurement errors are not a problem.
• Measuring technique: Measure each window's width and height at 3 points each (width: top, middle, bottom; height: left, center, right). Use the largest value to avoid light gaps caused by uneven windows.
• Measure individually: Even if windows or doors appear identical in size, measure each one separately to avoid subtle discrepancies causing incorrect orders.
• Fullness flexibility: Prefer a looser, more luxurious drape? Go with 2.2×. Prefer a neater, more tailored look? 1.6× works well. Adjust based on your decor style and window size.
• Special shapes: For bay windows, corner windows, arched windows, and other irregular shapes, take photos + measurements and send them to customer service. We'll recommend the best dimensions to avoid measuring errors.
