Details, formula, and sources
ScopeSection, post, rail, and picket counts for a straight fence run from the run length, post spacing, rails per section, and picket width. Corner and gate posts are field-judgment extras; the two end posts are already counted.
Formula or tableSections = ceil(run / spacing); posts = sections + 1; rails = sections x rails/section; pickets = ceil(run x 12 / (picket width + gap)).
