Use this guide to determine how much wire you need to enclose your yard. These figures are estimates, based on typical layouts. You may need more wire if you're doing interior loops to boundary off gardens, swimming pools or other protected areas.

To Cover This Size Area You Need This Amount of Wire

1/4 Acre 500 Feet

1/2 Acre 600 Feet

1 Acre 1000 Feet

2 Acres 1300 Feet

3 Acres 1500 Feet

4 Acres 1800 Feet

5 Acres 2000 Feet

For larger areas, use the following formula:

Multiply the total acreage by 43,000- i.e.: 10 acres x 43,000 = 430,000

Find the square root of the above number - square root of 430,000 = 656 (this is the length of each side of a 10 acre area that is square in shape. Even if your area is not square, if you multiply this number by four, this is the approximate length of the four sides of a 10 acre area.)

Therefore, one would need approximately 2,625 feet of wire to enclose the perimeter of a 10 acre area. You will need additional wire to run from the transmitter to the perimeter and/or for any interior loops, etc.
