Panels for 100 ft at 8 ft width?
14 panels with 10% waste buffer.
Fence materials are **panels = ceil(linear ft with waste ÷ panel width)** and **posts = ceil(linear ft ÷ post spacing) + 1**.
**Formula:**
Linear ft = Fence length × (1 + waste% / 100)
Panels = ceil(Linear ft ÷ Panel width)
Posts = ceil(Linear ft ÷ Post spacing) + 1
**Example — 100 ft run, 8 ft panels, 10% waste:**
110 linear ft → **14 panels**, **15 posts**

Posts = sections + 1 — always add a post at the run end.
Corners and gate posts need **10% minimum** extra linear ft.
Check local code for fence height and setback before digging.
