Fabric Yardage for Curtains Estimator: Calculate Your Perfect Curtain Fabric
When it comes to creating custom curtains, one of the most common challenges is figuring out exactly how much fabric you need. Too little fabric, and your curtains may look skimpy or uneven. Too much, and you risk wasting money and materials. That’s where our Fabric Yardage for Curtains Estimator comes in — a practical, easy-to-use tool designed to give you precise fabric requirements based on your window size, panel count, fullness preference, and curtain style.
Whether you’re sewing a cozy living room drapery, luxurious bedroom panels, or sheer café curtains, this tool ensures you get just the right amount of material, saving time, effort, and money.
How the Fabric Yardage for Curtains Estimator Works
Our curtain fabric calculator is built on practical sewing experience, translating complex measurements into simple, actionable numbers. Here’s how it works:
1. Key Inputs
The tool asks for a few essential parameters:
-
Window Width – Enter the width of your window in inches or centimeters.
-
Curtain Length / Drop – Decide how long your curtains should hang.
-
Number of Panels – Commonly 2 panels, but 1–4 options are supported.
-
Fullness / Gathering Factor – Standard fullness is 2×, luxurious fullness ranges 2.5–3×.
-
Curtain Style – Rod pocket, grommet, tab top, pinch pleat, or sheer, which affects extra fabric allowances.
-
Units – Imperial (inches/yards) or Metric (cm/meters).
2. Calculation Logic
The calculator uses simple but accurate formulas:
Step 1: Determine total fabric width per panel
For example, a 60-inch window with 2 panels at 2× fullness:
(60 ÷ 2) × 2 = 60 inches per panel
Step 2: Add extra length for hems and headers
-
Rod pocket: +12 inches
-
Grommet: +8 inches
-
Pinch pleat: +10 inches
-
Sheer: +10 inches
Step 3: Compute total fabric area
Step 4: Convert to yards/meters
Finally, we add a 10% buffer for pattern alignment, shrinkage, and mistakes.
The result shows the exact fabric yardage and a recommended purchase amount rounded to the nearest yard or meter.

Step-by-Step Examples
Example 1: Standard Living Room Curtains
-
Window Width: 60 inches
-
Curtain Length: 84 inches
-
Panels: 2
-
Fullness: 2×
-
Style: Rod pocket
Calculation:
-
Width per panel =
(60 ÷ 2) × 2 = 60 inches -
Total length per panel =
84 + 12 = 96 inches -
Fabric needed =
(60 × 96 × 2) ÷ (36 × 36) ≈ 8.9 yards -
With 10% buffer → 10 yards recommended
Example 2: Bedroom Pinch Pleat Curtains
-
Window Width: 72 inches
-
Curtain Length: 90 inches
-
Panels: 2
-
Fullness: 2.5×
-
Style: Pinch pleat
Calculation:
-
Width per panel =
(72 ÷ 2) × 2.5 = 90 inches -
Total length per panel =
90 + 10 = 100 inches -
Fabric needed =
(90 × 100 × 2) ÷ (36 × 36) ≈ 13.9 yards -
With 10% buffer → 16 yards recommended
Example 3: Sheer Café Curtains
-
Window Width: 48 inches
-
Curtain Length: 60 inches
-
Panels: 1
-
Fullness: 1.5×
-
Style: Sheer
Calculation:
-
Width per panel =
48 × 1.5 = 72 inches -
Total length per panel =
60 + 10 = 70 inches -
Fabric needed =
(72 × 70 × 1) ÷ (36 × 36) ≈ 3.9 yards -
With buffer → 5 yards recommended
