是什么 Fence Calculator?

▾

A fence calculator estimates the materials needed for a fencing project: posts, panels, concrete, rails, and fixings. It ensures you order the right quantity without expensive surplus.

PrimeCalcPro provides professional-grade tools trusted by businesses and academics.

如何 Fence Calculator

▾
  1. 1Measure total fence length in metres or feet
  2. 2For panel fencing: Number of panels = total length / panel width (typically 1.8m/6ft)
  3. 3Number of posts = number of panels + 1 (posts go between and at each end)
  4. 4Concrete per post: typically 10–15 kg of dry mix for a 600mm deep, 300mm diameter footing

例题解析

▾
示例 1
已知:20m fence · 1.8m panels
结果:12 panels · 13 posts · 13 bags concrete

20÷1.8=11.1 → 12 panels

💡

专业提示

Set fence posts at least 600mm deep (one-third of total post length) in concrete for stability. In frost-prone areas, go 750mm to get below the frost line.
