About this calculator
Overview
Building a fence involves three main layers: the vertical posts that provide structure, the horizontal rails that span the posts, and the pickets that provide coverage. This calculator helps you determine the exact quantity of each component, assuming a standard 3-rail design for maximum picket stability.
💡
Pro Tips
Always round your post count up to the next whole number; you can't install half a post.
If you're using pre-made panels, your spacing is fixed by the panel width (usually 8ft).
Include a 10% waste factor for pickets to account for warped, split, or damaged boards in the bundle.

Fun Facts
"Standard post spacing is usually 6 or 8 feet (1.8m or 2.4m) to match standard dimensional lumber lengths."
"Post holes should be at least 1/3 the total length of the post for structural integrity."
"Most privacy fences use 3 rails (top, middle, bottom) to prevent picket bowing or warping over time."
