How to Use This Calculator
Enter Fence Dimensions
Input fence length and height in feet. These define the overall fence size for picket calculations.
Enter Picket Specifications
Input picket width and spacing in inches. Common picket widths: 3.5" (1×4), 5.5" (1×6). Typical spacing: 1-2 inches for traditional picket fence appearance.
Enter Post and Rail Information
Input post spacing (typically 6-8 feet) and number of rails (typically 2-3 rails). These affect post and rail quantities.
Calculate and Review
Click "Calculate Picket Fence" to see number of pickets, picket linear feet, posts, rails, concrete, and cost estimates. Use this for material planning and cost estimation.
Formula
Coverage per Picket = Picket Width + Spacing
Pickets Per Foot = 1 / (Coverage per Picket / 12)
Number of Pickets = ⌈Fence Length × Pickets Per Foot⌉
Picket Linear Feet = Number of Pickets × Picket Height
Example 1: 100 ft fence, 4 ft height, 3.5" pickets, 1.5" spacing
Step 1: Coverage = 3.5 + 1.5 = 5.0" = 0.417 ft
Step 2: Pickets Per Foot = 1 / 0.417 = 2.4 pickets per foot
Step 3: Number of Pickets = ⌈100 × 2.4⌉ = 240 pickets
Step 4: Picket Linear Feet = 240 × 4 = 960 linear feet
Step 5: Number of Posts (8 ft spacing) = ⌈100 / 8⌉ + 1 = 14 posts

Understanding Picket Fences
Basic Principle: Picket fences consist of vertical pickets (boards) with gaps between them. Coverage per picket = Picket Width + Spacing. Pickets per foot = 1 / (Coverage / 12). Number of pickets = ⌈Fence Length × Pickets Per Foot⌉. Traditional picket spacing: 1-2 inches for classic appearance.
Picket Spacing: Picket spacing (gap between pickets) affects appearance and privacy. Traditional spacing: 1-2 inches for classic picket fence. Smaller spacing (0.5-1") provides more privacy. Larger spacing (2-3") provides more open appearance. The calculator shows coverage percentage.
Material Requirements: Typical materials: Pickets (1×4 or 1×6 boards, 3.5" or 5.5" wide), Posts (4×4, every 6-8 feet), Rails (2×4, 2-3 rails per section), Concrete (for post holes), Screws/Nails (for fastening).
Tips for Best Results
- Accurate Dimensions: Measure fence length and height accurately
- Correct Picket Width: Use actual picket width (not nominal) for accurate calculations
- Consider Spacing: Traditional spacing is 1-2 inches for classic appearance
- 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 pickets for a fence?
Coverage per Picket = Picket Width + Spacing. Pickets Per Foot = 1 / (Coverage / 12). Number of Pickets = ⌈Fence Length × Pickets Per Foot⌉. For example, 100 ft fence, 3.5" pickets, 1.5" spacing: Coverage = 5.0" = 0.417 ft, Pickets Per Foot = 2.4, Number of Pickets = ⌈100 × 2.4⌉ = 240 pickets. The calculator does this automatically.
What is typical picket spacing?
Typical picket spacing: 1-2 inches for traditional picket fence appearance. Smaller spacing (0.5-1") provides more privacy but uses more pickets. Larger spacing (2-3") provides more open appearance but uses fewer pickets. Traditional spacing (1-2") balances appearance and material cost.
What picket width should I use?
Common picket widths: 3.5" (1×4 nominal, actual 3.5"), 5.5" (1×6 nominal, actual 5.5"). Narrower pickets (3.5") are traditional and use more pickets. Wider pickets (5.5") use fewer pickets but are less traditional. Choose based on desired appearance and budget.
How many posts do I need for a picket 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 pickets for waste?
Yes, add 5-10% extra pickets for waste, cutting, and variations. For example, if calculator shows 240 pickets, order 252-264 pickets. This accounts for damaged pickets, cutting waste, and measurement errors. Always round up to nearest full quantity when ordering.
