TIMBER FENCING CALCULATOR
Calculate the materials needed for your project with our easy-to-use fence calculator. Enter the height and length of your fence to receive instant estimates, including area coverage and posts and rails. Perfect for accurate planning and budgeting!
Fence Cost Calculator
Our fence cost calculator helps estimate the cost of a fence based on standard post spacing, fence type and material quantities.
Fence costs can vary depending on:
Fence height and length
Type of fencing (panels, slatted fencing, etc.)
Post spacing and post size
Ground conditions and fixing methods
Accurate spacing is important — incorrect post centres or missing materials can quickly increase costs. This calculator is designed to reduce guesswork and help you plan fencing projects more confidently.
Please note: Results are estimates only and are intended as a guide, not a fixed quotation.
