Fence Calculator
Posts, panels, and concrete for a fence project.
Materials estimate
Add ~10% to your post and panel count for waste, corner adjustments, and the section that always ends up shorter than the panel width. Buy gate posts in 4×4 or 6×6 even if line posts are 4×4. Concrete estimate assumes two 60 lb bags per post in a standard 8-inch hole. Check your local frost depth.
