The Privacy Fence Estimator calculates complete material takeoffs for residential wood boundary fences, including structural 4×4 posts, horizontal 2×4 rails, vertical pickets, and post-setting concrete bags.

### Structural Dimensions & Material Formulas Fencing takeoff formulas calculate components from perimeter length, post spacing, and picket dimensions: - **Fence Bay Sections**: $$\text{Sections} = \left\lceil \frac{\text{Total Fence Length (ft)}}{\text{Post Spacing (ft)}} \right\rceil$$ - **4×4 Structural Posts**: $$\text{Posts Count} = \text{Sections} + 1$$ - **Horizontal 2×4 Rails**: $$\text{Rails Count} = \text{Sections} \times \text{Rails per Section (2 or 3)}$$ - **Vertical Dog-Ear Pickets**: $$\text{Pickets Count} = \left\lceil \frac{\text{Total Length (ft)} \times 12}{\text{Picket Width (in)}} \right\rceil$$ - **Post-Setting Concrete**: $$\text{Concrete Bags (50 lb)} = \text{Posts Count} \times 2$$

### Worked Takeoff Example Estimating lumber for a 120-foot residential perimeter fence with 8-foot post spacing, 3 horizontal rails per section, and 5.5-inch dog-ear pickets: - **Fence Sections**: $120 / 8 = 15\text{ bays}$ - **4×4 Posts Needed**: $15 + 1 = 16\text{ posts}$ - **2×4 Rails**: $15 \times 3 = 45\text{ rails}$ - **Vertical Pickets**: $(120 \times 12) / 5.5 = 1{,}440 / 5.5 \approx 262\text{ pickets}$ - **Fast-Setting Concrete**: $16 \times 2 = 32\text{ bags (50-lb)}$
