This guide supports a material takeoff. It does not choose post spacing, footing depth, gate structure, or a code-compliant fence design.
Measurement steps
- Draw each straight run and give it a simple label.
- Mark endpoints that are physically shared at corners so the same post is not counted twice.
- Measure each run along the intended post centreline.
- Mark the beginning and width of every gate as a clear face-to-face opening. Do not enter a nominal gate-leaf size.
- Record the actual face width of the posts you intend to use.
- Record actual board, panel, rail-stock, kerf, fastener-package, and cap information from the selected products.
For a connected corner, reuse one endpoint in both runs. For independent runs, keep their endpoints separate. Panel residuals are calculated per bay because an offcut cannot be assumed to fit another bay.
Field checklist
- Run labels and centreline lengths
- Shared corners and independent endpoints
- Clear gate start positions and widths
- Actual post face width
- Maximum post spacing supplied by the user’s plan
- Board or panel dimensions
- Rail-stock lengths, saw kerf, and reusable-offcut threshold
- Product fastening rates and package quantities
- Separate contingency choices
Call 811 Before You Dig and follow the applicable utility-marking process before digging. Procedures and waiting periods vary by state.
Common mistakes
- Mixing clear gate width with post-centre spacing
- Aggregating panel length before rounding each bay
- Treating package surplus as installation waste
- Assuming a valid material count proves structural adequacy
- Letting the calculator invent a rail count, fastening rate, or post-spacing rule
