What is Board and Batten?

Board and batten is a classic wall treatment that creates visual interest and architectural depth. It consists of wide vertical boards installed with narrow horizontal battens that cover the seams between boards.

This style is popular for:

  • Exterior walls - Adding curb appeal and protection
  • Interior accent walls - Creating focal points in rooms
  • Porches and entryways - Traditional architectural style
  • Barn conversions - Rustic aesthetic enhancement

How Board and Batten Calculator Works

The calculator uses precise mathematical formulas to determine material requirements:

Board Quantity = (Wall Length × 12) ÷ (Board Width + Spacing) + 1

Where:

  • Wall Length = Total horizontal measurement in feet
  • Board Width = Width of individual boards in inches
  • Spacing = Gap between boards in inches

Key Concepts Explained

Board Width

Typically 5-8 inches wide. Wider boards create a more modern look, narrower boards are more traditional.

Board Spacing

Gap between boards, usually 6-12 inches. Affects the overall pattern and material requirements.

Batten Width

Narrow strips (1-3 inches) that cover seams. Provides structural integrity and aesthetic appeal.

Batten Spacing

Vertical distance between battens, typically 16-24 inches. Creates the horizontal rhythm of the design.
