Building a fence? Get accurate material estimates for posts, rails, pickets, panels, concrete, and hardware. This calculator covers wood, vinyl, chain link, and aluminum fencing with cost estimates to help you budget your project.
A fence consists of posts (set in concrete), horizontal rails connecting posts, and vertical pickets or panels. Post spacing varies by fence type—typically 6-10 feet apart. Wood fences use individual pickets; vinyl and aluminum use pre-made panels; chain link uses mesh rolls. Each type has different material requirements and costs.
Post Calculation
Posts = ⌈Fence Length ÷ Post Spacing⌉ + 1 + (Gates × 2)6-foot wood or vinyl fence with close-set pickets for backyard privacy.
4-foot fence—chain link is economical; wood provides privacy and containment.
Standard fencing to mark property lines—consider local regulations and HOA rules.
Posts should be set 1/3 of their above-ground height deep, with a minimum of 2 feet. A 6-foot fence needs posts set 2-3 feet deep. Use 2 bags of concrete per post for secure installation.
Wood fences: 6-8 feet. Vinyl/aluminum: 6 feet. Chain link: 10 feet. Closer spacing means more posts but a sturdier fence. Windy areas benefit from closer spacing.
Order 10-15% extra for pickets and panels to account for cuts, defects, and future repairs. Posts and rails can be ordered closer to exact amounts since they're less likely to be damaged.
Chain link is cheapest initially. Wood is moderate cost with higher maintenance. Vinyl costs more upfront but lasts 20+ years with minimal maintenance. Consider total lifetime cost, not just installation.
