Fence Cost Calculator

A fence is a repetitive structure — count one section accurately and you've priced the whole line. Enter your fence length, post spacing and local prices: you get post count, section count, rail count, picket count and a total material cost you can take to the hardware store.

How the takeoff is counted

Posts = length ÷ spacing + 1; Rails = sections × rails per section; Pickets = (length × 12) ÷ (picket width + gap)

Posts sit 6–8 feet apart (8 ft is standard for wood privacy fence). Every post for a privacy fence needs concrete — see our concrete bag calculator for that part of the order.

Pickets are counted with their gap: a 5.5-inch picket on a privacy fence (no gap) gives about 2.2 pickets per foot. Adjust the gap for shadowbox or spaced-picket styles.

Prices vary hugely by region and lumber market — the defaults here are US big-box 2026 ballparks. Enter your real local prices; the math updates instantly.

Frequently asked questions

How far apart should fence posts be?

8 feet is standard for wood privacy fences; 6 feet for windy areas or heavier gates. Never exceed the rail's rated span.

How many bags of concrete per post?

Two 50-lb bags (or one 80-lb) per standard 4×4 post in normal soil — use the concrete bag calculator for the full count.

Does this include gates or labor?

No. Add gate hardware separately, and labor typically equals materials — pros often quote $30–60 per linear foot installed.
