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=⌊B+SW+S⌋
Where:
- W = wall width
- B = batten width
- S = space between battens
Total Batten Length Formula
L=N×H
Where:
Case 2: When Desired Number of Battens Is Selected
Spacing Between Battens Formula
S=N−1W−(N×B)
Where:
- N = desired number of battens
Total Batten Length Formula
L=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=⌊B+SW+S⌋
Substitute values:
N=⌊0.25+1.520+1.5⌋
N=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=N−1W−(N×B)
Substitute values:
S=1120−(12×0.25)
S≈1.55
Results:
- Number of Battens: 12
- Spacing Between Battens: 1.55 ft
