How it’s calculated
- 1
Sections are the fence length ÷ post spacing, rounded up; posts are one more than sections.
- 2
Pickets are about 5½ inches wide with a small gap, so roughly 2 per foot of fence.
- 3
Each post is usually set in about two 50 lb bags of concrete.
Before you buy
Add one post for each corner and two for each gate.
Check your property line and local fence rules (height, setbacks, permits) before you dig.

Questions
How far apart should fence posts be?
Most wood fences use posts 6 to 8 feet apart. Closer spacing makes a sturdier fence, especially in high wind.
How deep should fence posts be?
A common rule is a third to half of the post's above-ground height, and below the frost line in cold climates.
