Formula and method
Bays = ceil(run length/maximum spacing). A straight open run requires bays + 1 posts.
Worked example
A 30 m run with maximum spacing 2.4 m needs 13 bays and 14 posts. Evenly spaced bays are about 2.3077 m long.

One straight run without gates or corners. Rail price assumes one piece per bay. Closed loops, gates, shared corner posts, foundations, pickets and site rules require separate planning.
How this was calculated
Bays = ceil(run length ÷ maximum post spacing).
An open straight run has one more post than bays.
Frequently asked questions
Does this include gates or a closed loop?
No. Those layouts change post and hardware counts. The model covers one straight open run, excluding foundations and pickets.
