Field notes
Set your corner and end posts first, string a line between them, and space the rest to that line — eyeballing post spacing leaves a fence that waves. Dig post holes about a third of the post height deep and below your frost line, or a winter heave will lift them. Budget one to two bags of fast-setting concrete per post; the calculator counts sections, but the hole depth is what holds the fence up.
