What this means
A simple fence is made of pickets, posts and horizontal rails. Pickets are spaced by their own width plus the gap, so the count is the fence length divided by one picket-plus-gap unit, rounded up. Posts sit at fixed intervals along the run, plus one for the end. The rail count is a choice — typically two rails for a picket fence, three for a taller or sturdier one. Everything is measured along the horizontal run, not the diagonal, so the math stays straightforward.
Recommendations
- Set posts in concrete (about a 20 kg bag per hole) — a solid post is what keeps the whole fence straight.
- Space posts at 2–2.4 m; wider spacing looks cheaper but lets the rails sag over time.
- For privacy you'll want no gap — that changes the picket count significantly, so adjust the gap field to 0.
Watch out
- This estimate assumes a straight run — corners and changes in height need extra posts and cuts.
- Check local height restrictions and boundary rules before building a boundary fence.
