How Curtain Fabric Is Calculated

Understanding the logic builds trust—and helps you make smarter buying decisions.

Step 1: Calculate Number of Panels

Panels = (Window Width + 12 inches) ÷ 20

Then we round the result:

• 3.2 → 3 panels
• 3.6 → 4 panels

Why +12 inches?
This ensures proper curtain coverage and stacking space.

---

Step 2: Calculate Fabric per Panel

This depends on curtain type:

• Window curtains → Height + 24 inches
• French door curtains → 2.5 meters (standard)
• Ceiling curtains → 3 meters (full-length styling)

This includes allowances for:

• Stitching
• Folds
• Proper drape

---

Step 3: Calculate Total Fabric

Total Fabric = Panels × Fabric per Panel

For wide fabric:

Total Fabric = Panels × 1.2 meters

Final output is shown in meters, making it easy to purchase fabric directly.

Fabric Width Options Explained (Choose Smartly)

Choosing the right fabric width changes everything—cost, finish, and effort.

---

48 / 54 Inch Fabric (Standard Width)

• Most commonly used fabric
• Requires panel-based stitching
• More joins and tailoring work

Best for:

• Budget-friendly setups
• Custom curtain designs

---

108 / 120 Inch Fabric (Wide Width)

• Covers more width with fewer panels
• Requires less stitching
• Cleaner, seamless look

Calculation logic:

Panels × 1.2 meters

Note:
There may be some fabric wastage—always collect leftover fabric from your tailor.
