People sometimes ask the question: How many panels do I need to build a round yard or pen for horses?

Often we need to calculate how many panels we would need to build a horse round yard or round pen (also known as a round corral). This free calculator allows you to enter the number of panels and the length of the panels to work out the area or diameter or radius.

Enter the number of panels and the length of them and click on the "Calculate" button. This will tell you the area and the radius of the round yard. If you wish to enter some different quantities of panels or different length panels, click on the "Clear All" button and enter your new quantities and lengths.

If you enter the panel length as metres, the area will be shown as square metres and the radius as metres. If you enter the panel length as feet, the area shown will be square feet and the radius as feet.

To work out the diameter of the round yard, multiply the radius by two.
