Drapery Yardage Calculator
The Drapery Yardage Calculator helps determine the amount of fabric required for making curtains or drapes. This ensures you purchase the right amount of fabric, reducing waste and ensuring a perfect fit.
Formula
The formula for calculating drapery yardage is:
Yardage (Y) = (Width (W) × Height (H) × Number of Panels (N)) / 36
How to Use
- Enter the width (W) of your drapery panel in inches.
- Input the height (H) of the drapery in inches.
- Enter the number of panels (N) required.
- Click “Calculate” to get the total fabric yardage needed.
Example
If you are making 2 panels, each with a width of 50 inches and a height of 90 inches:
- Y = (50 × 90 × 2) / 36
- Y = 250 yards
