Details, formula, and sources

Section, post, rail, and picket counts for a straight fence run from the run length, post spacing, rails per section, and picket width. Corner/end/gate posts are field-judgment extras.

Sections = ceil(run / spacing); posts = sections + 1; rails = sections x rails/section; pickets = ceil(run x 12 / (picket width + gap)).

Standard fence-layout identities.
