Calculate the Number of Panels for Your Round Pen
1. To find the number of panels required to build a round pen the size you want, multiply the desired diameter (distance of a straight line passing through the center of the pen) by 3.14. This will determine the circumference (the distance around the outside of the round pen).
2. Divide the circumference by the length of panels being used. This will equal the number of panels needed.
3. The chart below will give you a general idea of the number of panels you need along with an entrance gate or arch the same length of the panels in the row you will be using.
