Calculate Fence Posts, Rails and Pickets
A free fence calculator that works out the materials for a straight fence run. Enter the total length, the post spacing and the rails per section, and it returns the number of posts, sections, rails and — if you add a picket width — the pickets.

The post count includes one post at each end. Gates, corners and sloping ground change the layout, so treat the result as a starting estimate.
