About This Calculator
Calculate all the materials needed for your fence project including posts, rails, pickets, gates, concrete, and hardware. This fence calculator covers wood privacy fences, vinyl panels, chain link, and metal fencing with accurate cost estimates for DIY or contractor quotes.
2026 fence costs: Wood privacy fencing runs $25-$45 per linear foot installed, with cedar at the higher end ($35-$45/LF) and pressure-treated pine at the lower end. Vinyl fencing costs $36-$65 per linear foot installed—more expensive upfront but virtually maintenance-free for 20-30 years. Chain link remains the budget option at $12-$25 per linear foot installed for 4-6 foot heights.
For a typical 150-foot backyard fence, expect to pay:
- Wood privacy (6'): $3,750-$6,750 installed, $1,800-$3,000 DIY materials
- Vinyl privacy (6'): $5,400-$9,750 installed, $3,000-$5,000 DIY materials
- Chain link (4'): $1,800-$3,750 installed, $750-$1,500 DIY materials
Labor costs have increased 8-12% since 2024 due to skilled labor shortages. DIY installation can save 40-50% but requires proper planning—always call 811 before digging to locate underground utilities, check local setback requirements, and verify you don't need a permit. Many jurisdictions require permits for fences over 6 feet or near property lines.
How to Use the Fence Calculator
- 1Enter the total linear feet of fencing needed (measure perimeter or single run accurately).
- 2Specify the number of walk gates (3-4 feet wide) and drive gates (10-16 feet) required.
- 3Select your fence type: wood privacy, vinyl, chain link, aluminum, or split rail.
- 4Choose fence height: 4', 6', or 8' (check local codes for height restrictions).
- 5Select post spacing: 6 feet (stronger) or 8 feet (standard) between posts.
- 6Review the materials list: posts, rails, pickets/panels, concrete, and hardware.
- 7Toggle pricing mode to compare DIY materials cost vs. professional installation.
Formula
Posts = (Linear Feet ÷ Post Spacing) + 1 + (Gates × 2)Divide total fence length by post spacing (6 or 8 feet), add 1 for the end post. Each gate requires 2 additional posts (one on each side). Corner posts are already counted in the linear calculation. Add 1 extra post per inside corner for proper bracing.

Gate Post Requirements:
- Use posts one size larger than line posts
- 6×6 posts for wood gates over 4 feet wide
- 4" steel posts for chain link drive gates
- Set gate posts extra deep (6-12" more than line posts)
- Concrete gate posts in cold climates
Common Gate Mistakes:
- Posts too small—gates sag within months
- Posts not deep enough—lean inward over time
- No diagonal brace—gates rack and won't latch
- Wrong hinge type—hinges fail under weight

|---|---|---|
| Layout and string lines | — | 2-3 hours |
| Digging post holes | 15-30 min/hole | 6-12 hours |
| Setting posts | 20-30 min/post | 6-10 hours |
| Concrete curing | — | 24-48 hours wait |

When to Hire a Pro:
- Rocky or clay soil (post hole nightmare)
- Significant slope (requires stepping/racking)
- Property line uncertainty
- Pool fence (code compliance critical)
- Timeline under 1 week
- You don't own or want to rent equipment
When DIY Makes Sense:
- Flat, workable soil
- Simple rectangular layout
- No permit required
- Flexible timeline (weekend project)
- You enjoy physical work
- Budget is primary concern
Essential DIY Tools:
| Tool | Own/Rent | Cost |
|---|---|---|
| Post hole digger (manual) | Own | $40-$80 |
| Auger (power) | Rent | $50-$100/day |
| Level (4 ft) | Own | $25-$50 |
| String line | Own | $10-$20 |
| Circular saw | Own | $80-$200 |
| Drill/driver | Own | $80-$200 |
| Safety gear | Own | $30-$60 |
Pro Tips
- 💡Call 811 at least 3 days before digging—it's free, required by law, and locates all underground utilities.
- 💡Set corner and end posts first, then string a line between them for perfectly straight intermediate posts.
- 💡Use pressure-treated or naturally rot-resistant posts (cedar, redwood) for ground contact—regular lumber rots within 3-5 years.
- 💡Apply post preservative to cut ends before setting—the cut exposes untreated wood to moisture.
- 💡Check local codes for height restrictions, setbacks, and permit requirements before purchasing materials.
- 💡Add 10% extra pickets for cutting waste, defects, and future repairs—matching wood later is difficult.
- 💡Install pickets with a gap (1/4"-1/2") to allow for wood expansion—tight-fit pickets buckle in humidity.
- 💡Consider "good neighbor" (shadowbox) style if neighbors will share costs—alternating pickets look finished on both sides.
- 💡Set gate posts deeper (6-12" extra) and in oversized concrete footings—gates create leverage that loosens shallow posts.
- 💡Pre-stain or seal all wood components before installation—once assembled, end grain is inaccessible.
- 💡For sloped yards, decide between stepped panels (level sections) or racked panels (follow slope)—both are acceptable.
- 💡Get at least 3 quotes from contractors and verify they're licensed and insured—fence quality varies dramatically.
Frequently Asked Questions
With standard 8-foot post spacing: 100 ÷ 8 = 12.5 sections, requiring 14 posts (13 + 1 end post). For 6-foot spacing: 100 ÷ 6 = 16.7 sections = 18 posts. Add 2 extra posts per gate (walk gates need 2 posts, drive gates need 2). Add 1 extra post per inside corner for proper bracing. For a typical 100 LF fence with one walk gate: 14 + 2 = 16 posts at 8' spacing.
