How to Calculate Your Round Pen
- To find the number of panels needed, multiply the desired diameter (straight line passing through the center of the circle) by 3.14. This will determine the circumference (the distance around the circle).
- Divide the circumference by the length of panels being used. This will equal the number of panels needed.
