About this calculator
Post spacing drives everything. Eight feet on centre is the norm for wood privacy fence; shorter spans cost more in posts but hold up better in wind and clay soil.

FAQ
How does the fence calculator work?
Post spacing drives everything. Eight feet on centre is the norm for wood privacy fence; shorter spans cost more in posts but hold up better in wind and clay soil. The underlying maths is: Posts = (Length ÷ Spacing) + 1. Pickets = Length ÷ Picket width, plus gap.
What do I need to enter?
7 values: fence length, post spacing, fence height, picket width, price per post, price per picket, and labour. Each field starts with a sensible default, so you can change one number at a time and watch the result move.
What does the total fence cost result mean?
It is returned as a money amount in US dollars and updates live as you edit the inputs, so you can compare two or three versions of a scenario in a few seconds.
Is this calculator free, and do I need an account?
Yes, it's free, and no account is required. Nothing you type is stored on our servers — the maths runs entirely in your browser.
How accurate is the result?
It applies the standard formula exactly, so the arithmetic is precise. Estimates assume standard, average conditions — local rules, pricing, and materials vary.
Who is this tool for?
It's built for anyone doing everyday planning maths — a quick estimate that would otherwise need four browser tabs and a calculator app.
Accuracy and limitations
- Estimates assume standard, average conditions — local rules, pricing, and materials vary.
- Results are rounded for readability; add a buffer before ordering, booking, or committing.
- Double-check anything with a real cost attached against a local quote.
