Circle Skirt Yardage Calculator

Formula

The formula to calculate the yardage needed for a circle skirt (Y) is:

\[ Y = \left(\frac{W}{2 \pi} + L + H\right) \times 2 \div 36 \]

Where:

Y – The yardage needed.
W – The waist circumference in inches.
L – The desired length of the skirt in inches.
H – The hem allowance in inches.
\(\pi\) – The mathematical constant Pi (approximately 3.14159).

Definition

Circle Skirt: A type of skirt that is cut in the shape of a circle with a hole in the center for the waist. This design creates a full, flowing skirt that drapes beautifully and moves gracefully.
Waist Circumference (W): The measurement around the waist.
Desired Length of Skirt (L): The length from the waist to the hem.
Hem Allowance (H): The additional fabric needed for hemming.

Example

Let's say the waist circumference (W) is 30 inches, the desired length of the skirt (L) is 25 inches, and the hem allowance (H) is 1 inch. Using the formula:

\[ Y = \left(\frac{30}{2 \times 3.14159} + 25 + 1\right) \times 2 \div 36 \approx 1.71 \text{ yards} \]

So, the yardage needed for the circle skirt is approximately 1.71 yards.
