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

  1. 1Enter the total linear feet of fencing needed (measure perimeter or single run accurately).
  2. 2Specify the number of walk gates (3-4 feet wide) and drive gates (10-16 feet) required.
  3. 3Select your fence type: wood privacy, vinyl, chain link, aluminum, or split rail.
  4. 4Choose fence height: 4', 6', or 8' (check local codes for height restrictions).
  5. 5Select post spacing: 6 feet (stronger) or 8 feet (standard) between posts.
  6. 6Review the materials list: posts, rails, pickets/panels, concrete, and hardware.
  7. 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 Hardware Costs:

ComponentCostNotes
Heavy-duty hinges (pair)$30-$60Self-closing available
Gate latch$15-$50Keyed locks $40-$100
Drop rod (double gates)$25-$50Prevents sagging
Spring closure$20-$40Auto-close for pools
Gate wheel$30-$60Prevents drag

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:

  1. Posts too small—gates sag within months
  2. Posts not deep enough—lean inward over time
  3. No diagonal brace—gates rack and won't latch
  4. Wrong hinge type—hinges fail under weight

Permits, Codes, and Property Lines

Legal requirements vary by jurisdiction—always verify locally:

Typical Permit Requirements:

SituationPermit Usually Required?
Fence under 6 feet, interior lotOften no
Fence 6+ feet tallUsually yes
Front yard fenceUsually yes
Corner lot (any fence)Usually yes

Permit Costs:

  • Residential fence permit: $50-$200
  • Plan review: $25-$75 (if required)
  • Inspection fee: Often included
  • Expedited processing: +$50-$100

Common Height Restrictions:

HOA communitiesVaries (check CC&Rs)

Before Building:

  1. Survey: Get property survey or locate pins ($300-$800)
  2. Call 811: Locate underground utilities (free, required)
  3. Check codes: Height, setback, material restrictions
  4. Notify neighbors: Required in some states for line fences
  5. HOA approval: Get written approval if applicable
  6. Permit: Apply if required (2-4 week approval typical)

Pool Fence Requirements (IRC):

  • Minimum 48" height
  • No openings >4" (can't pass 4" sphere)
  • Self-closing, self-latching gates
  • Latch 54" above grade (or key/combination)
  • No climbable features

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

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.
