Fence Post Formula

Posts = (Fence Length ÷ Post Spacing) + 1 + Corner Posts + Gate Posts + Extra %

The number of fence posts is calculated based on the fence length and desired spacing. Always add one extra post for the end, plus additional posts for corners, gates, and a percentage for replacements and errors.
