If you like doing math yourself, here’s a simple way to calculate fabric yardage:
-
Measure your window’s width and height.
-
Multiply width by your chosen fullness (1.5x–3x).
-
Add hem allowance (about 10 inches).
-
Divide by fabric width to find fabric panels needed.
-
Multiply panel height by panels count to get total yards of fabric.
Example:
Window width = 80 in, height = 84 in, fabric width = 54 in, fullness = 2x
