Board & batten wainscoting is a classic interior design technique that enhances walls with vertical wooden strips (battens) over panels. While aesthetically appealing, calculating the exact number of battens, spacing, and top/bottom boards for a wall can be challenging. The Board & Batten Wainscoting Calculator is a specialized tool designed to make this process simple, accurate, and fast.

Whether you are a professional contractor or a DIY enthusiast, this tool helps plan materials efficiently, reduce waste, and ensure a flawless installation.


How the Tool Works

This calculator helps you determine:

  • Number of battens needed for your wall
  • Total batten length required
  • Exact spacing between battens
  • Length of top and bottom horizontal boards (optional)

It does this by considering your wall dimensions, batten width, desired spacing, and whether you want horizontal boards at the top and bottom. The results give precise measurements for a professional-looking finish.


Step-by-Step Instructions to Use the Wainscoting Calculator

Follow these steps for an accurate calculation:

1. Enter Wall Length

Input the total wall length in feet. This is the horizontal measurement of the wall you want to cover with wainscoting.

2. Enter Wainscoting Height

Provide the height of your wainscoting in feet. Typical heights range from 3 to 4 feet but can be customized based on your design preference.

3. Specify Batten Width

Set the width of the vertical battens in inches. Common widths are 2–3 inches, but you can adjust according to style.

4. Set Spacing Between Battens

Enter the spacing between each batten in inches. Consistent spacing ensures symmetry and a professional look.

5. Include Top & Bottom Boards (Optional)

Choose Yes or No to add horizontal boards at the top and bottom of the wainscoting for added stability and design polish.

6. Calculate Results

Click the “Calculate” button. The tool displays a progress bar while processing and then shows:

  • Number of battens
  • Total batten length
  • Actual spacing between battens
  • Top & bottom board lengths (if selected)

Practical Example

Imagine you have a wall that is 12 ft long and you want a wainscoting height of 4 ft. You plan to use 2-inch-wide battens with 6-inch spacing and want top & bottom boards.

By entering these values:

  • Wall Length: 12 ft
  • Wainscoting Height: 4 ft
  • Batten Width: 2 in
  • Spacing: 6 in
  • Include Top & Bottom Boards: Yes

The calculator provides:

  • Number of Battens: 21
  • Total Batten Length: 84 ft
  • Spacing Between Battens: 6 in
  • Top & Bottom Boards: 12 ft each

This precise measurement ensures minimal waste and a perfect visual layout.
