About This Calculator
Estimate all the materials you need for a wood privacy fence: posts, pickets, rails, and concrete. Adjust spacing and dimensions to match your specific fence design.
Standard Post Spacing
- 8 ft — Most common for wood privacy fences
- 6 ft — Stronger, better for high-wind areas
- 10 ft — Only for light-duty or decorative fences
Frequently Asked Questions
How many posts do I need for a 100 ft fence?
At 8 ft spacing, you need 14 posts for a 100-foot fence. This includes one post at each end and one every 8 feet between them.
How deep should fence posts be?
Fence posts should be buried at least 1/3 of their height. For a 6 ft fence, dig holes 2 ft deep. In cold climates, go below the frost line (typically 3-4 ft).
