Calculation Method & Assumptions
Our wood fence estimating model accurately mirrors stick-built contractor framing practices based on structural spans, post hole excavation depths, and verified regional lumber rates:
1. Post & Section Spacing Formula
Wooden fences are engineered around 8-foot (2.44 m) post-to-post spans to prevent horizontal 2x4 rails from sagging under picket weight and wind load:
Posts = Sections + 1 End Post (+ Gates)
2. Horizontal 2x4 Rails Formula
Rail counts scale with fence height to support vertical pickets: 4-foot fences require 2 horizontal rails; 6-foot standard privacy fences require 3 rails; 8-foot tall fences require 4 rails per 8-foot section:
3. Picket Takeoff by Style
Pickets use nominal 1x6 boards (actual face width of 5.5 inches or 0.4583 ft). Solid privacy installs pickets edge-to-edge (1.0x); shadowbox alternates pickets on both sides (1.15x); spaced picket leaves 2-inch gaps (0.65x).
4. Concrete Footing Depth
Each 4x4 post requires 1 to 2 bags of concrete mix poured into a 9-inch-diameter hole excavated 24 to 36 inches deep (below regional frost lines) to prevent seasonal tilting.
Factors Affecting Wood Fence Costs
1 Lumber Species & Grade
Pressure-treated pine is the most economical choice ($12 to $22 per linear foot), offering chemical protection against termites and rot. Western Red Cedar and Redwood cost 30% to 50% more ($18 to $35/ft) but offer tight natural grain, less warping, and pleasant aroma.
2 Fence Height & Wind Shear
Standard residential fences are 6 feet tall. Moving to an 8-foot fence requires 10-foot or 12-foot 4x4 or 5x5 posts, four 2x4 rails instead of three, 33% more picket surface area, and deeper concrete footings to handle high wind resistance.
3 Construction Style & Board Density
Solid privacy fences require ~22 pickets per 10 linear feet. Shadowbox styles overlap boards on opposite sides of the rail to create a neighbor-friendly look while allowing breeze passage, requiring 15% more lumber and fasteners.
4 Ground Slope & Stepping
Properties with significant slope require either custom stair-stepped panels (which require longer downhill posts) or racked contoured fences. Rocky subsoil, clay, or tree roots can increase digging labor significantly.
5 Gate Framing & Hardware
Gates are the most common failure point on wood fences. Heavy wood gate leaves require anti-sag diagonal truss brackets, reinforced hinge posts, and heavy-duty galvanized powder-coated steel hardware.
6 Staining, Sealing & Maintenance
Unfinished wood greys within 6 to 12 months. Applying professional penetrating oil stain or semi-transparent water-seal adds $1.50 to $3.50 per square foot, protecting lumber fibers from solar ultraviolet degradation and water absorption.

Frequently Asked Questions
How much does it cost to install a wood fence in 2026?
In 2026, building a new wood fence typically costs between $15 and $38 per linear foot installed ($12 to $26/ft for pressure-treated pine, and $18 to $35+/ft for cedar or redwood). For a standard 150-linear-foot suburban backyard, total installation usually ranges from $2,500 to $5,800 including posts, 2x4 rails, pickets, concrete footings, and contractor labor.
Which wood is best for fencing: Pine, Cedar, or Redwood?
Pressure-treated pine is the most economical and resists insect burrowing and subterranean fungal rot, but can warp or shrink under harsh sunlight if not sealed. Western Red Cedar and California Redwood contain natural oils that prevent rot and shrinkage with superior dimensional stability, making them the gold standard for premium residential privacy fences.
How many posts, rails, and pickets do I need for a wood fence?
Wood fences are built in 8-foot (2.44 m) spans between 4x4 posts. Divide total linear footage by 8 and add 1 for the end post. Each 8-ft section requires 2 horizontal 2x4 rails for a 4-ft fence, 3 rails for a 6-ft fence, and 4 rails for an 8-ft fence. Standard 5.5-inch dog-ear pickets require approximately 2.18 pickets per linear foot for solid edge-to-edge privacy.
How deep should wood fence posts be set in concrete?
For a standard 6-foot wood fence, 4x4 posts should be set 24 to 36 inches deep (typically one-third of the total post height or below your municipal winter frost line). Anchoring each post in 1 to 2 bags of concrete prevents seasonal frost heave and prevents wind shear from tilting the fence.
How much does it cost to tear down and remove an old wood fence?
Demolishing and disposing of an existing wooden fence generally costs $3.00 to $8.00 per linear foot ($450 to $1,200 for a 150-ft fence run). Costs cover manual dismantling, cutting posts, jackhammering old concrete footings, and waste disposal haul-away.
How long does a wood fence last?
A properly installed pressure-treated wood fence lasts 15 to 20 years, while western red cedar and redwood last 20 to 25+ years. Applying UV-resistant oil-based water-seal stain every 2 to 3 years prevents greying, splitting, and premature weathering.
Do I need building permits to build a wooden fence?
Most cities allow backyard wood fences up to 6 feet tall without special architectural variances, but require a permit and inspections. Front-yard fences are frequently restricted to 3.5 or 4 feet to preserve road visibility. Always contact your local building department and dial 811 before digging.
