Vinyl Fence Calculator
Plan your home & garden project with our free vinyl fence calculator. Get precise measurements, material lists, and budgets.
Formula
Panels = ceil((Total Length - Gate Openings) / Panel Width); Posts = Panels + 1 + (Gates x 2)
Subtract all gate openings from the total fence length, then divide by panel width and round up to get panel count. Posts are one more than panels for line runs, plus two additional posts for each gate opening. Estimate one bag of concrete per post for proper setting.
Worked Examples
Example 1: Backyard Privacy Fence
Problem: 200 linear feet of 6-foot tall vinyl privacy fence with 8-ft panels and one 4-ft gate.
Solution: Fence length = 200 - 4 = 196 ft\nPanels = ceil(196 / 8) = 25\nLine posts = 25 + 1 = 26\nGate posts = 2\nTotal posts = 28\nConcrete bags = 28
Result: 25 panels, 28 posts, 28 bags concrete
Example 2: Front Yard Picket Fence
Problem: 100 linear feet of 4-foot vinyl picket fence with 6-ft panels and two 3-ft gates.
Solution: Fence length = 100 - 6 = 94 ft\nPanels = ceil(94 / 6) = 16\nLine posts = 17\nGate posts = 4\nTotal posts = 21
Result: 16 panels, 21 posts, 21 bags concrete
Frequently Asked Questions
How much does a vinyl fence cost per foot?
Vinyl fence costs range from $15 to $40 per linear foot for materials, depending on height and style. A 4-foot picket fence costs about $15 to $20 per foot, a 6-foot privacy fence runs $25 to $35 per foot, and decorative styles with lattice tops can exceed $40 per foot. Installation labor adds another $15 to $30 per foot. Total installed cost for a standard 6-foot privacy vinyl fence typically falls between $40 and $65 per linear foot.
How deep should vinyl fence posts be set?
Vinyl fence posts should be set to a depth equal to one-third of the above-ground height plus 6 inches. For a 6-foot fence, set posts approximately 30 inches deep (24 inches for one-third of 72 inches, plus 6 inches). Use a post hole diameter of 10 to 12 inches and fill with concrete or compacted gravel. In areas with freeze-thaw cycles, posts should extend below the frost line to prevent heaving.
How long does vinyl fencing last?
Quality vinyl fencing typically lasts 20 to 30 years with minimal maintenance. Unlike wood, vinyl does not rot, warp, or require painting or staining. UV-inhibited vinyl resists fading and discoloration from sun exposure. The main maintenance requirement is occasional cleaning with soap and water or a pressure washer on low setting. Vinyl can become brittle in extreme cold, so avoid impacts during winter months.
How many panels and posts do I need for my vinyl fence?
Divide your total fence length (minus gate openings) by the panel width, which is typically 6 or 8 feet for vinyl. You need one more post than the number of panels for straight runs, plus two additional posts for each gate. For example, 200 feet of fencing with 8-foot panels requires 25 panels and 26 line posts. Each corner also needs a post, and end posts may need to be reinforced with concrete.
