How to Calculate Fence Materials
Measure your yard perimeter or the total linear feet you need to fence. The calculator determines posts, rails, pickets, and concrete based on your fence style and dimensions.
Fence Styles & Cost
- Privacy (6ft wood): Solid boards with no gaps. $20-35/linear foot installed. Most popular for backyards
- Picket (3-4ft): Classic style with spacing between boards. $15-25/ft. Good for front yards and decorative borders
- Ranch/split rail: Open horizontal rails. $10-18/ft. Best for large properties and rural settings
- Vinyl privacy: No painting or staining ever. $30-45/ft. Higher upfront cost but near-zero maintenance
- Chain link: Most affordable. $8-15/ft. Functional but limited aesthetics
Material Quantities per 8-Foot Section
- Posts: 1 per section (4×4 for most fences, 6×6 for gates and heavy panels)
- Rails: 2 for fences under 5 feet, 3 for 6-foot and taller
- Pickets: 16 for privacy (no gap), 10-12 for picket style (with gaps)
- Concrete: 2 bags of 60-lb quick-set per post hole
Post Depth & Spacing
- Bury 1/3 of the total post length: a 6-foot fence needs posts 9 feet long, buried 3 feet deep
- Standard post spacing: 8 feet on center
- Use 6-foot spacing in high-wind areas or for added rigidity
- Gate posts should be 6×6 and set deeper (3.5-4 feet) to handle the extra stress
Before You Build
- Call 811 at least 3 days before digging — it's free and locates underground utilities
- Check local regulations: Most areas limit fence height to 6 feet in backyards and 4 feet in front yards. Some HOAs have additional rules
- Get a survey: Build on your property line, not your neighbor's. Disputes are expensive
- Talk to neighbors: Fence placement and style can affect their property value and sunlight
Installation Tips
- Set corner, end, and gate posts first, then string a line between them for the rest
- Let concrete cure 24-48 hours before attaching rails and pickets
- Leave a 2-inch gap between the bottom of the fence and ground to prevent rot
- Apply wood stain or sealant within 6 months of installation — untreated wood warps and grays
- For wood fences, use pressure-treated lumber rated for ground contact (UC4A or UC4B) for posts
