Determining the square footage of your fencing requires accurate measurements and a simple algebraic equation. It is easier to calculate your square footage if your fence line is consistently high along its entire length. However, if your fencing has sections of different heights you can still calculate the total square footage by measuring each section individually and adding the results.


Step 1

Use your measuring tape to determine the linear length of your fence line in feet. This measurement is your fence width and the first variable in your equation.

Step 2

Measure the height of your fence in feet. This measurement is the second variable in your equation.

Step 3

Multiply the width by the height. The result is the square footage of your fence. For example, if your width is 500 feet and your height is six feet, your equation would be as follows: 500 x 6 = 3,000. The square footage of your fence is 3,000.
