Fence post spacing formula
Sections = round up(fence length ÷ target spacing). Posts for a straight run = sections + 1.
Planning notes
This is a quick straight-run estimate. Gates, corners, changes in direction, end posts and structural requirements can add posts beyond the basic spacing calculation.
- Corners, gates and changes of direction often need additional posts.
- Local wind loads and fence type can affect suitable post spacing.
