How to Calculate Fence Materials
Calculating fence materials requires knowing your total linear footage, the fence style, and standard component dimensions. Our calculator uses industry-standard post spacing and material counts for accurate estimates.
Fence Post Formula
Posts = (Total Linear Feet ÷ Post Spacing) + 1
+ Corner Posts + Gate Posts
Posts = (Total Linear Feet ÷ Post Spacing) + 1
+ Corner Posts + Gate Posts
Fence Material Comparison
| Material | Cost/Linear Ft | Lifespan | Maintenance |
|---|---|---|---|
| Wood Privacy | $15–30 | 15–20 yrs | High |
| Chain Link | $10–20 | 20–30 yrs | Low |
| Vinyl | $20–40 | 25–30 yrs | Very Low |
| Aluminum | $25–40 | 30+ yrs | Very Low |
| Split Rail | $10–18 | 15–25 yrs | Low |
Installation Tips
- Call 811 (USA) before digging to locate underground utilities
- Check local ordinances — many areas limit fence height to 4 ft in front yards, 6 ft in back
- Set posts in concrete for maximum stability, especially in sandy soils
- Allow concrete to cure 24–48 hours before attaching rails and panels
- Slope boards at the bottom if the ground is uneven rather than cutting posts
? Frequently Asked Questions
How many fence posts do I need?
Posts are typically spaced 8 feet apart. Divide your total linear footage by 8 and add 1 for the end post. Corner and gate posts require additional posts. Our calculator handles all of this automatically.
How much does a fence cost per linear foot?
Wood privacy fence runs $15–$30/linear ft installed. Chain-link is $10–$20/ft. Vinyl fence costs $20–$40/ft. Aluminum fence runs $25–$40/ft. These are installed prices including materials and labor.
How deep should fence posts be set?
Posts should be set 1/3 to 1/2 of their total length underground. For a 6-ft fence, use 9-ft posts set 3 ft deep. In areas with frost, posts must go below the frost line (typically 36"–48" deep).
What is the standard fence panel width?
Standard fence panels are 8 feet wide. Posts are typically spaced at 8-foot intervals to accommodate standard panels. Some styles use 6-foot spacing for added strength.
How long does a wood fence last?
Pressure-treated pine lasts 15–20 years. Cedar and redwood last 15–30 years with proper maintenance. Annual staining or sealing significantly extends the life of wood fences.
