Fence Post & Panel Calculator

Planning Your Fence Project

Fencing projects in Grayson County range from simple split-rail boundary markers to full privacy fence installations around residential properties. The post count is the most critical calculation — each post requires a hole dug below the frost line (typically 30–36 inches in Grayson County), concrete, and a set time before the fence boards go on.

Post Spacing and Structural Considerations

Standard privacy fence posts are set 6 feet on center — this matches the width of standard pre-made fence panels and is the most economical spacing. For farm fence or split-rail, 8-foot spacing reduces post count. Post diameter and length depend on fence height: a 6-foot privacy fence needs 8-foot posts set 24–30 inches deep, leaving approximately 5.5–5.75 feet above grade after concrete cures.

All fence posts must be set in concrete. Use the post hole concrete calculator to estimate 80 lb bag count per hole. For a standard 6-foot fence with 8-inch diameter holes at 30-inch depth, plan on 1–2 bags per hole.

Wood vs. Vinyl Fence

Wood (typically pressure-treated pine or cedar) costs less upfront but requires annual or biennial maintenance. Vinyl fence costs 30–50% more initially but requires almost no maintenance. In western Kentucky's climate — hot humid summers and wet springs — vinyl's moisture resistance makes it a compelling choice for long-term value. UIR installs both.
