Count fence pickets spaced along a fence line.
Each picket plus its gap forms a repeating unit, so the number of pickets is the fence span divided by that unit, rounded up. Total board feet scales that count by picket size. Picket spacing sets the look and privacy of a fence, and counting by the repeating unit keeps the material order right.
Picket Count
Pickets = (fence length x 12 + gap) / (picket width + gap)
Pickets = (fence length x 12 + gap) / (picket width + gap) Each picket plus its gap forms a repeating unit, so the number of pickets is the fence span divided by that unit, rounded up. Total board feet scales that count by picket size.
