Fence Calculator with Cost
Add your unit price to see the full material cost, not just the count, for your fence project.
Runs locally in your browser — your measurements never leave this pageTry: Perimeter=100, Panel width=6, Post spacing=8, Waste=10, Price per panel/post=8, Units=ft → 100.00 ft, 6 ft, 8 ft, 19, 14, $264.00
How to use
Enter the total perimeter, the panel width (often 6 ft) and the post spacing (often 8 ft). The calculator returns panels and posts, with one extra post for the start of the run and a 10% waste margin.
FAQ
Why one extra post?
A run of panels needs a post at both ends, so posts = panels + 1 (plus corner posts at direction changes).
What if my fence is not a rectangle?
Measure the full walking distance around the fence line and enter that as the perimeter.
How much waste for a slope?
Stepped or racked panels on a slope waste more — budget 15%.
