Board and batten siding creates a strong vertical pattern using evenly spaced battens across a wall. Getting the spacing right is critical for both appearance and material planning.

This Board and Batten Spacing Calculator allows users to calculate batten layout in two flexible ways:

  • By Space Between Battens
  • By Desired Number of Battens

The calculator automatically returns:

  • Number of battens
  • Spacing between battens
  • Total batten length

Calculator Modes Explained

1) Space Between Battens Mode

Use this option when you already know how much space you want between each batten.

Inputs used:

  • Wall Width
  • Batten Width
  • Space Between Battens

2) Desired Number of Battens Mode

Use this option when you want a specific number of battens across the wall.

Inputs used:

  • Wall Width
  • Batten Width
  • Desired Number of Battens

Output Values

  • Number of Battens
  • Spacing Between Battens
  • Total Batten Length

Formulas Used in the Calculator

Case 1: When Space Between Battens Is Selected

Number of Battens Formula

N=⌊W+SB+S⌋N = \left\lfloor \frac{W + S}{B + S} \right\rfloorN=⌊B+SW+S​⌋

Where:

  • WWW = wall width
  • BBB = batten width
  • SSS = space between battens

Total Batten Length Formula

L=N×HL = N \times HL=N×H

Where:

  • HHH = wall height

Case 2: When Desired Number of Battens Is Selected

Spacing Between Battens Formula

S=W−(N×B)N−1S = \frac{W - (N \times B)}{N - 1}S=N−1W−(N×B)​

Where:

  • NNN = desired number of battens

Total Batten Length Formula

L=N×HL = N \times HL=N×H

Example Calculation

Given:

  • Wall Width: 20 ft
  • Batten Width: 0.25 ft

Example A: Using Space Between Battens

Space Between Battens = 1.5 ft

Step 1: Calculate Number of Battens

N=⌊W+SB+S⌋N = \left\lfloor \frac{W + S}{B + S} \right\rfloorN=⌊B+SW+S​⌋

Substitute values:

N=⌊20+1.50.25+1.5⌋N = \left\lfloor \frac{20 + 1.5}{0.25 + 1.5} \right\rfloorN=⌊0.25+1.520+1.5​⌋

N=12N = 12N=12

Results:

  • Number of Battens: 12
  • Spacing Between Battens: 1.5 ft

Example B: Using Desired Number of Battens

Desired Number of Battens = 12

Step 1: Calculate Spacing Between Battens

S=W−(N×B)N−1S = \frac{W - (N \times B)}{N - 1}S=N−1W−(N×B)​

Substitute values:

S=20−(12×0.25)11S = \frac{20 - (12 \times 0.25)}{11}S=1120−(12×0.25)​

S≈1.55S \approx 1.55S≈1.55

Results:

  • Number of Battens: 12
  • Spacing Between Battens: 1.55 ft
