Try: Perimeter=100, Panel width=6, Post spacing=8, Waste=10, Price per panel/post=0, Units=m → 328.10 ft, 6 ft, 8 ft, 61, 43

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%.
