About this calculator

Overview

The perimeter is the foundation of your entire fence project estimate. In many residential cases, you may not need to fence all four sides of a lot due to existing structures, neighboring fences, or natural boundaries. This calculator allows you to customize which sides are included in the total linear measurement.

Pro Tips

Confirm property lines with a professional surveyor to avoid the costly mistake of installing a fence on city or neighbor's land.
Subtract the width of any existing gates or buildings that will act as part of the perimeter barrier.
Identify utility lines (dial 811 in the USA) before finalizing the placement of any corner or end posts.

Fun Facts

"Fenced sides for a backyard typically include two lengths and one width (U-shape), assuming the house closes the fourth side."
"Property setbacks often require fences to be placed 2-6 inches (5-15cm) inside the actual property line to avoid disputes."
"A standard 1/4 acre rectangular lot usually requires between 300-400 linear feet of fencing for a full enclosure."

Formula: Perimeter = (Quantity of Length Sides × L) + (Quantity of Width Sides × W)
