How to Calculate How Many Fence Posts to Use

Warning

Spray paint is a chemical compound that is under pressure and poses threats to people, pets and the environment. Read and follow all of the manufacturer's recommendations before and during use of spray paint. Always wear appropriate safety equipment, such as leather work gloves, a dust mask and safety glasses when using spray paint.

Building a fence is a complicated procedure that begins with accurately calculating the materials needed. Nails, cross boards, concrete and posts are only some of the materials required to build a fence. To determine the number of fence posts needed for a project you will need some time, a few tools and a bit of know-how.

Determine the exact placement of the fence. Walk around the property and examine the layout. Keep in mind that sudden dips or rises will disturb the structure. Mark the entire fence line with a dotted line using the spray paint.

Determine the placement of any gates or corners. Mark those spots with an "X" using the spray paint.

Lay out the 100-foot tape measure along the fence line using a gate post or corner as a starting point. Spray an "X" across the dotted line every 8 feet. Any "X" marks already in place for gates or corners that are within 8 feet of the previous mark can take the place of any new "X."

Count the number of spray-painted "X" marks. This is the total number of fence posts you will need for the project. The layout is complete and ready for construction of the fence to begin.
