The Fence Length Needed for Circular Area calculator computes the fencing materials needed to enclose a roughly circular area based on the diameter, length of fence segments and the number of rows of rails.
INSTRUCTIONS: Choose units and enter the following:
(D) Diameter of Circular Enclosure
(LS) Length of Segments
(nR) Number of Rails
Circular Fence Materials: The calculator provides the following:
(nS) Number of Sides or Side Panels
(nRB) Number of Rail Boards
(nP) Number of Posts
(P) Perimeter of Circular Area in feet.
(A) Size of Area in square feet.
The Math / Science
First, a circular fenced in area (paddock) isn't really a circle. It's a roughly circular polygon with a number of equal sides for each section. A common application of circular paddock is for a ring enclosure for horses. These are also known as horse round yards or round pens. A circulars shape lets the rider exercise the horse in a circle and achieve more than a walk.
The Post and Rail (split-rail) Pricing table contains recent fence prices for a variety of fence components with prices from Lowes, Home Depot, Menards and potentially other stores based on their web sites. The prices are in U.S. dollars.
CAUTION: The pricing information provided is for calculating convenience with NO implied guarantees to the accuracy of the values listed. Authoritative sources should be sought to confirm any value before risking health or wealth on the veracity of the data. Furthermore, Calc gives no guarantee that you will be able to buy products at listed prices or even if they will be available. The data provided is purely a convenience for making estimates, so we repeat, ALWAYS use local pricing and authoritative specifications.
Perimeter of a Rectangular Shaped Area computes the length of a fence perimeter in a rectangular shaped area base on the length (l) and width (w) of the area.
Diagonal of Rectangle Areacomputes the diagonal measurement of a rectangular area. This is useful in ensuring that your area has square corners.
Three Sided Land Fencing: Computes the number of fencing segments or posts needed to go around a three sided fence area.
Circular Fence Calc computes the diameter, number of posts, rails, perimeter and area of a circular shaped fenced area (paddock).
Fencing Needed for Polygon Area: Computes the area and side length enclosed within a polygon (e.g. octagon) shaped area (paddock).
Area Fenced in Polygon: Computes the area enclosed in polygon (e.g., 12 sided) fence area based on the length and number of individual sides.
Fencing Needed for Circular Area computes the number of posts, number of sections, sides or panels, number of rail boards, perimeter and area of a ROUGHLY CIRCULAR shaped area (paddock) based on a diameter and length of sides.
