Fence materials
Plan a straight run of posts, rails and pickets.
How this works
Bays = ceiling(length ÷ maximum spacing); posts = bays + 1. Rails and pickets are estimated separately.
Example
Using the example inputs, posts for one straight run is 14 posts.
- Straight fence length
- 100 ft
- Maximum post spacing
- 8 ft
- Rails per bay
- 2
- Picket width
- 5.5 in
- Gap between pickets
- 0 in
- Waste allowance
- 10 %
- Posts for one straight run
- 14 posts
No gates or corners. Picket estimate uses full run length without subtracting post widths.
Scope and assumptions
Material planning only. Check local permissions, footing requirements, actual lumber sizes and manufacturer details.
