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).
