How Our Board and Batten Calculator Works
Our board and batten calculator uses industry-standard measurements and professional installation techniques to calculate accurate material requirements and cost estimates. The calculation accounts for board width, batten width, spacing requirements, and waste factors to ensure you have enough materials for your project.
Board and Batten Calculation Formula
Number of Boards = Wall Width ÷ (Board Width + Spacing)Number of Battens = Number of Boards - 1Total Linear Feet = (Boards + Battens) × Wall HeightTotal Cost = Material Cost + Labor CostThis formula calculates the optimal number of boards based on your wall dimensions and desired spacing. Battens typically cover the seams between boards, so the number of battens is one less than the number of boards. Total linear feet determines material quantity, and costs include both materials and professional installation.

Material and Installation Standards
Board and batten siding follows specific installation standards for proper function and appearance. Boards are typically 6-12 inches wide, with battens 2-4 inches wide covering the seams. Spacing between boards should allow for wood expansion (1/8" to 1/4") while being fully covered by battens. Installation requires proper backing, moisture barriers, and correct fastening techniques.
- Standard board widths: 6", 8", 10", or 12"
- Standard batten widths: 2", 2.5", or 3"
- Expansion gap: 1/8" to 1/4" between boards
- Material waste factor: 10-15% additional
- Installation rate: 3-4 hours per 100 sq ft
- Fastener spacing: 16-24 inches on center

Project Specifications:
- Wall dimensions: 10ft × 20ft (200 sq ft)
- Board width: 8 inches
- Batten width: 2 inches
- Board spacing: 0.5 inches
- Material cost: $3.50 per linear foot
Calculation Steps:
- Calculate board spacing: 8" + 0.5" = 8.5"
- Number of boards: 240" ÷ 8.5" ≈ 29 boards
- Number of battens: 29 - 1 = 28 battens
- Board length: 29 × 10ft = 290 linear feet
- Batten length: 28 × 10ft = 280 linear feet
- Calculate material and labor costs
Result: 3 boards + 2 battens = $530 total cost
Estimated installation time: 6 hours for professional installation.
Small Accent Wall Example
8ft × 10ft wall with 6" boards
~15 boards, 14 battens ≈ $350-600
Full Exterior Wall Example
12ft × 40ft wall with 10" boards
~58 boards, 57 battens ≈ $1,800-3,200
