Posts & panels for a fence run
Building a fence? Enter the total run length to estimate the posts and panels you need at standard 8-foot spacing.
Posts and panels
With 8-foot sections you need one post per section plus one to close the run, and one panel per section. For each section, plan 2–3 rails. Set posts in concrete — about one 50 lb bag of fast-setting mix per hole.
