Planning an Acreage Fence? Get the Fencing Footage Formula to Enclose 1-2 Acres
Installing fencing around acreage allows homeowners, farmers, and ranchers to enclose and protect their property. But determining the required linear footage of fencing for 1-2 acres can be tricky.
With some basic measurements and calculations, you'll get an accurate estimate to buy the right amount of fencing material.
Determine the Exact Shape and Size of the Property
The first step is to carefully map out the boundaries of the acreage using measurements and stakes. Note any irregular shapes or corners that may impact the total perimeter. This process provides the precise dimensions you'll need for subsequent calculations.
For a 1-2 acre rectangular plot, you can simply measure the length and width. But many properties have more complex boundaries based on geography, roads, easements etc. Meticulously mapping the site provides critical information.
Calculate the Total Perimeter Length
Once you've delineated the property boundaries, add up the length of all sides to determine the total perimeter. This provides the complete distance around the outer edge of the land parcel.
For a simple square or rectangular site, you can just take the length and width measurements and multiply as needed to calculate perimeter. But allow extra perimeter length if the acreage has an irregular shape.
Perimeter Formulas
Here are some common perimeter formulas:
- Rectangle: Perimeter = 2(length) + 2(width)
- Square: Perimeter = 4(side length)
- Irregular shape: Add up all side lengths
Divide Perimeter Length by 500 Feet
With the total perimeter footage, divide that number by 500. Most standard fencing materials come in rolls of 500 linear feet. Dividing the perimeter by 500 determines the total number of fencing rolls required.
For example, if your 1 acre perimeter is 840 feet, 840/500 = 1.68 rolls. Round up and you would need 2 rolls of 500-foot fencing.
Purchase the Required Amount of Fencing
Using your calculations, purchase enough 500-foot rolls of fencing to enclose the acreage perimeter. Available fencing materials include wood, chain link, aluminum, welded wire, vinyl, and other styles.
Be sure to buy a little extra to account for any interior fencing needs or wastage during installation. And have a professional confirm you've purchased adequate fencing for the job.
Fencing Material Types
- Wood: Attractive, durable, provides privacy. Requires regular maintenance.
- Chain link: Secure, cost-effective option. Not the most aesthetically pleasing.
- Vinyl: Low maintenance, customize look, higher upfront cost.
Consult a Fencing Professional
For acreages larger than 2 acres, it's wise to have a professional fencing contractor calculate your specific needs. Complex perimeters with multiple corners and borders make DIY estimates challenging.
An expert can precisely determine the required linear feet of fencing based on the property survey. This ensures you don't purchase too little materials for the job.
Factor in Regulations and Permits
When installing acreage fencing, be sure to check local zoning laws, neighborhood HOA guidelines, and other relevant regulations. Most areas require permits for new fence construction, which involves submitting plans for approval.
Having a contractor handle permitting can streamline the process. But you'll want to be aware of any restrictions or requirements before starting your fencing project.
Estimating Fencing for a 1 Acre Parcel
For a square acre plot:
- 1 acre = 43,560 square feet
- Length of each side = square root of 43,560 = 209 feet
- Perimeter = 4 sides x 209 feet = 836 linear feet
So for a square 1 acre property, you will need approximately 835 linear feet of fencing material.
Estimating Fencing for 2 Acres
For a square 2 acre parcel:
- 2 acres = 87,120 square feet
- Length of each side = square root of 87,120 = 309 feet
- Perimeter = 4 sides x 309 feet = 1,236 linear feet
Therefore, for a square 2 acre property, you'd need around 1,235 linear feet of fencing.
Fence Height Considerations
While the perimeter length calculations don't change based on height, do factor in your desired fence height when selecting materials and installing.
For security, privacy or containing large animals, a 6, 7, or 8 foot tall fence may be preferable. Just know that taller fences often require more robust post holes and materials to withstand wind.
Accounting for Interior Fencing
The perimeter fencing footage estimates don't account for interior fencing you may want for gardens, pools, animal pens, or other uses.
Be sure to measure and calculate any interior fencing separately, and add it to your overall material requirements.
Determining the linear feet of fencing for acreage is easy with some simple calculations based on the property boundaries. Start by carefully mapping the site, calculating total perimeter, and dividing by 500 feet to estimate fencing rolls needed. Use this guide to take the guesswork out of planning an acreage fencing project.
