Fence Post Count

Determine how many fence posts you need for a straight run by combining the total fence length with your desired post spacing.

Measure the straight-line run excluding gate openings or corners. Use meters if you prefer—just stay consistent.
Typical wood fences use 6–8 ft spacing; chain-link and wire fences can stretch to 10 ft.

Check local building codes, homeowner association rules, and soil conditions before purchasing materials. Extra posts may be required for structural bracing, corners, or challenging terrain.

Examples

  • 180 ft fence with 8 ft spacing ⇒ 24 posts
  • 120 ft fence with 6 ft spacing ⇒ 21 posts
  • 75 ft fence with 7.5 ft spacing ⇒ 11 posts
  • 60 m fence with 2.4 m spacing ⇒ 26 posts

FAQ

Do I include corner or gate posts in this total?

No. The calculation covers a straight span. Add posts for corners, braces, and gate frames separately based on your layout.

How precise should my spacing measurement be?

Use the on-center distance between posts. Marking tape measures or layout strings beforehand helps maintain uniform spacing when you build.

Can I enter metric measurements?

Absolutely. Enter both length and spacing in meters (or any matching unit) and the math will stay consistent.

What if I am building on a slope?

Measure along the slope for each section or break the fence into segments. Steep grades may require closer spacing or stepped panels.

Additional Information

  • Formula: Posts = ceil(Fence length ÷ Spacing) + 1 to include both end posts.
  • Always round up—ordering an extra post or two covers measurement drift, terrain, or damaged pieces.
  • Add separate posts for each gate, corner, or brace assembly; this calculator models only a single straight run.
