Calculate how many posts and sections a fence needs for a given total length.

How It Works

How Fence Calculator Works

The total fence length is divided by your chosen post spacing to get the number of sections, and one extra post is added since a fence with n sections always needs n+1 posts (one at each end plus every point in between).

FAQ

Frequently Asked Questions

What post spacing is typical?
Most residential fence panels are designed for posts spaced 6 to 8 feet apart, matching standard pre-built panel widths — check your specific fence panel or picket system's spec before finalizing.
