Posts Needed vs Total Fence Length
Fence Calculation
Posts = (Total Length / Post Spacing) + 1
Rails = Sections × Rails per Section (2 for fences ≤6ft, 3 for taller)
Pickets = Total Length (in) / Picket Width
Add 10% for waste.
Example Calculation
100 ft fence, 6 ft tall, 8 ft spacing, 3.5 in pickets.
- 01Sections = ceil(100/8) = 13
- 02Posts = 13 + 1 = 14
- 03Rails = 13 × 2 = 26
- 04Pickets = ceil(1200 / 3.5) = 343
