Plan your perfect privacy fence with our Board-on-Board Fence Calculator. Easily estimate the number of pickets, rails, posts, and concrete needed for your project. This calculator helps DIYers and contractors accurately budget and purchase materials, ensuring a beautiful and durable fence with overlapping boards for complete privacy.
Formula:
This calculator determines material quantities based on your fence dimensions and design choices.
- Number of Pickets:
(Total Fence Length (in) / (Picket Width (in) - Picket Overlap (in))) - Number of Posts:
(Total Fence Length (ft) / Post Spacing (ft)) + 1 - Number of Rails:
(Total Fence Length (ft) / Post Spacing (ft)) * Number of Rails per Section - Bags of Concrete:
Number of Posts * Concrete Bags per Post
Where:
- Total Fence Length (L): The total linear footage of your fence.
- Picket Width (PW): The width of an individual picket board (e.g., 6 inches).
- Picket Overlap (PO): How much one picket overlaps the next (e.g., 1 inch).
- Post Spacing (PS): The distance between each fence post (e.g., 8 feet).
- Number of Rails (NR): Typically 2 for a standard fence or 3 for taller fences.
- Concrete Bags per Post (CP): The number of concrete bags required for each post hole.
