Calculation assumptions
- The fence is one continuous straight run; each gate adds one post beyond the continuous run count.
- Post spacing is treated as a maximum, so every partial bay creates a full additional bay.
- Pickets cover only total fence length minus entered gate width.
- Post depth, footing volume, bracing, wind load, terrain changes, corners, and gate hardware require project-specific verification.
Fence layout
How fence materials are estimated
Bays and posts
Divide by maximum post spacing and add gate post boundaries.
Rails and pickets
Apply rails per bay, picket face width and gap, then add waste.
Site boundary
Corners, slopes, and loads need a layout
The regular straight-run model excludes corners, elevation changes, braces, gate hardware, wind loading, post depth, footing volume, utilities, easements, and local height or setback rules.
