🔒 Privacy Fence Calculator
Calculate privacy fence materials and costs
Common: 5.5" (1×6)
Common: 0.75" (1×6)
How to Use This Calculator
Enter Fence Dimensions
Input fence length and height in feet. These define the overall fence size for material calculations.
Enter Board Specifications
Input board width and thickness in inches. Common board widths: 5.5" (1×6), 7.25" (1×8). Privacy fences typically use boards with minimal or no spacing.
Enter Post, Rail, and Gate Information
Input post spacing (typically 6-8 feet), number of rails (typically 2-3 rails), number of gates, and gate width. These affect post, rail, and gate quantities.
Calculate and Review
Click "Calculate Privacy Fence" to see number of boards, posts, rails, concrete, gates, and cost estimates. Use this for material planning and cost estimation.
Formula
Boards Per Foot = 1 / (Board Width / 12)
Number of Boards = ⌈Fence Length × Boards Per Foot⌉
Board Linear Feet = Number of Boards × Fence Height
Number of Posts = ⌈Fence Length / Post Spacing⌉ + 1
Example 1: 100 ft privacy fence, 6 ft height, 5.5" boards
Step 1: Board Width = 5.5 / 12 = 0.458 ft
Step 2: Boards Per Foot = 1 / 0.458 = 2.18 boards per foot
Step 3: Number of Boards = ⌈100 × 2.18⌉ = 218 boards
Step 4: Board Linear Feet = 218 × 6 = 1,308 linear feet
Step 5: Number of Posts (8 ft spacing) = ⌈100 / 8⌉ + 1 = 14 posts

Understanding Privacy Fences
Basic Principle: Privacy fences consist of closely spaced or overlapping boards to provide maximum privacy. Boards per foot = 1 / (Board Width / 12). Number of boards = ⌈Fence Length × Boards Per Foot⌉. Privacy fences typically have minimal or no spacing between boards for maximum privacy.
Board Spacing: Privacy fences typically have minimal or no spacing between boards for maximum privacy. Boards may overlap slightly or be butted together. This differs from picket fences which have visible gaps between pickets.
Material Requirements: Typical materials: Boards (1×6 or 1×8 boards, 5.5" or 7.25" wide), Posts (4×4, every 6-8 feet), Rails (2×4, 2-3 rails per section), Concrete (for post holes), Screws/Nails (for fastening), Gates (if needed).
Tips for Best Results
- Accurate Dimensions: Measure fence length and height accurately
- Correct Board Width: Use actual board width (not nominal) for accurate calculations
- Account for Overlap: Privacy fences may have slight board overlap
- Add Safety Margin: Add 5-10% extra for waste and cutting
- Verify Local Prices: Check local material prices for accurate cost estimates
Frequently Asked Questions
How do I calculate boards for a privacy fence?
Boards Per Foot = 1 / (Board Width / 12). Number of Boards = ⌈Fence Length × Boards Per Foot⌉. For example, 100 ft fence, 5.5" boards: Board Width = 5.5/12 = 0.458 ft, Boards Per Foot = 2.18, Number of Boards = ⌈100 × 2.18⌉ = 218 boards. The calculator does this automatically.
What is the difference between privacy fence and picket fence?
Privacy fences have closely spaced or overlapping boards for maximum privacy, while picket fences have visible gaps between pickets. Privacy fences typically use 1×6 or 1×8 boards with minimal spacing, while picket fences use narrower pickets (1×4) with visible gaps (1-2 inches). Privacy fences provide more privacy but less air flow.
What board width should I use for a privacy fence?
Common board widths: 5.5" (1×6 nominal, actual 5.5"), 7.25" (1×8 nominal, actual 7.25"). Wider boards (7.25") use fewer boards but may have gaps. Narrower boards (5.5") use more boards but provide better coverage. Choose based on desired appearance, budget, and availability.
How many posts do I need for a privacy fence?
Number of Posts = ⌈Fence Length / Post Spacing⌉ + 1. For example, 100 ft fence, 8 ft post spacing: Posts = ⌈100 / 8⌉ + 1 = 13 + 1 = 14 posts. The +1 accounts for the end post. Typical post spacing: 6-8 feet. The calculator does this automatically.
Do I need to add extra boards for waste?
Yes, add 5-10% extra boards for waste, cutting, and variations. For example, if calculator shows 218 boards, order 229-240 boards. This accounts for damaged boards, cutting waste, and measurement errors. Always round up to nearest full quantity when ordering.
