FAQ

How do I calculate fence picket spacing?

Estimate the number of pickets from span, picket width, and target gap, then recalculate the gap so the layout fills the span evenly.

Should gaps go at both ends?

This simple calculator assumes equal gaps across the span, including the outside edges.

Why is my exact gap different from the target gap?

The exact gap adjusts so the chosen picket count fits the total span without a partial board.
