Schritt-für-Schritt Beispielrechnung

Beispiel: Building a 100 ft long, 6 ft high wood privacy fence with 8 ft post spacing and 1 gate.

01

Calculate Sections: 100 ft ÷ 8 ft = 12.5 -> 13 bays.

02

Calculate Posts: 13 + 1 + 1 (gate post) = 15 posts.

03

Calculate Rails (3 per bay): 13 bays × 3 rails = 39 rails (2x4x8).

04

Calculate Pickets: (100 ft × 12 in) = 1200 in - 36 in (gate) = 1164 in ÷ 5.5 in/picket = 211.6 + 5% buffer = 223 pickets.

05

Calculate Concrete: 15 posts × 2 bags = 30 bags.

Result: Order 15 posts (4x4x8 or 4x4x9), 39 rails (2x4x8), 223 dog-ear pickets, 30 bags of fast-setting concrete, and 1,300 exterior screws.

Fence Materials Formula

Posts = ⌈ Length ÷ Spacing ⌉ + 1 + Gates; Pickets = ⌈ (Length × 12) ÷ Board Width ⌉ × 1.05

Dividing total length by post spacing gives the number of fence bays. Adding 1 yields line posts. Horizontal rails are computed as rails per bay (3 rails for 6ft fences). Picket counts divide net fence length by picket width plus 5% scrap buffer.

Formelvariablen

Post Count — Total 4x4 pressure-treated timber posts
Rails — Horizontal 2x4 framing rails (3 for 6ft fence, 2 for 4ft fence)
Concrete — 2 fifty-pound bags of fast-setting concrete per post hole

Berechnungsgrundlagen

  • Fence posts are buried at least 1/3 of total height in ground with 2 bags of concrete per post hole.
  • 6ft privacy fences require 3 horizontal rails (top, middle, bottom) to prevent board warping.
Trade FAQ

Häufig Gestellte Fragen

Typische Fragen von Heimwerkern und RenovierernZaunrechner

How deep should fence post holes be?

Post holes should be dug to at least 1/3 to 1/2 of the above-ground post height. For a 6-foot fence, dig 24 to 30 inches deep (or below your local winter frost line).

How many bags of concrete do I need per fence post?

Plan for two (2) 50 lb bags of fast-setting concrete per standard 4x4 post hole. For gate posts and corner posts carrying extra tension, use 3 bags.
