🚧 Fencing Calculator

Calculate materials needed for chain link, wood, vinyl, and other fence types.


Quick Formula​

Linear Feet​

Linear Feet = Perimeter of Area to Fence

Number of Sections​

Sections = Linear Feet Γ· Section Length

Posts Needed​

Posts = Sections + 1 (for end post) + Gates

Common Calculations​

Example: 100' Γ— 100' Yard​

Perimeter:

  • Perimeter = (100 + 100) Γ— 2 = 400 linear feet

Chain Link (6'):

  • Fabric: 400 LF
  • Posts: 400 Γ· 8 + 1 = 51 posts
  • Top rail: 400 LF
  • Tension wire: 400 LF

Wood Privacy (6'):

  • Posts: 400 Γ· 8 + 1 = 51 posts
  • Rails: 400 Γ— 3 = 1,200 LF
  • Pickets: 400 Γ— 20 = 8,000 pickets (1/2" spacing)
  • Concrete: 51 Γ— 0.5 CF = 25.5 CF = ~1 CY

Gate Considerations​

Standard Gate Sizes​

TypeWidthUse
Pedestrian3-4'Walk-through
Single vehicle10-12'Car, truck
Double vehicle16-20'Large vehicles

Gate Materials​

  • Gate frame - Match fence material
  • Hinges - 2-3 hinges per gate
  • Latch - Gate latch
  • Post reinforcement - Heavier posts for gates

Post Footings​

Concrete Volume​

Volume = Ο€ Γ— radiusΒ² Γ— depth

Example: 8" diameter Γ— 3' deep

  • Radius = 4" = 0.33 feet
  • Volume = 3.14 Γ— 0.33Β² Γ— 3 = 1.03 cubic feet
  • Per post: ~0.5-1.0 cubic feet

Waste Factor​

Add 5-10% for:

  • Cutting
  • Waste
  • Mistakes


Plan for Gates

Don't forget to account for gates in your material calculations. Gates require heavier posts and additional hardware.
