Planning sequence
Measure fence runs by straight section
Corners, gates, slope changes, and property turns should break the fence into separate runs. This keeps panel counts, rail spans, and post positions easier to check.
Place ends, corners, and gates first
End posts, corner posts, and gate posts set the structure. After those are placed, line posts can be spaced between them using the chosen panel width or rail span.
Estimate concrete from hole size and count
Concrete needs depend on post count, hole diameter, hole depth, soil, frost depth, gate load, and fence height. Gate posts and corner posts may need larger holes than line posts.
Count finish materials separately
Panels, pickets, rails, posts, caps, fasteners, hinges, latches, stain, and concrete are different material groups. A complete shopping list should keep them separated.
Planning assumptions
| Post spacing | Many wood fences use spacing near 6-8 ft, but systems vary. |
|---|---|
| Gate posts | Gate posts often need stronger posts and more concrete. |
| Picket count | Use picket width plus gap to estimate count across a run. |
| Waste | Add extra pickets, rails, and fasteners for cuts, defects, and repairs. |
Common mistakes
Counting only panels
Posts, gates, rails, caps, hardware, and concrete can be a large part of the job.
Ignoring slopes
Stepped panels and racked panels need different planning.
Using one hole size for every post
Corner and gate posts may need more support than line posts.

How do I estimate fence posts?
Place end, corner, and gate posts first, then divide each run by the planned spacing and round up.
How do I estimate pickets?
Subtract gate openings, divide the remaining run by picket width plus gap, then round up and add extras.
How much concrete does a fence need?
Estimate one post hole from diameter and depth, multiply by post count, divide by bag yield, then round up.
