Worked example

Board and Batten Spacing for a 12 Foot Wall

This layout example uses a 12 ft wall, 2.5 in battens, and 18 in desired spacing to estimate count and adjusted spacing.

Inputs used in this example

  • Wall width: 12 feet.
  • Batten width: 2.5 inches.
  • Desired spacing: 18 inches.

Expected output

The calculator estimates 8 vertical battens with about 17.71 inches of adjusted clear spacing between battens.

When to adjust this example

  • Check the layout around outlets, windows, baseboards, corners, and existing trim.
  • This is a spacing layout only, not a complete board and batten material list.
  • Rails, panels, adhesive, nails, caulk, paint, and trim should be planned separately.

Formula explanation

  1. Convert 12 feet to 144 inches.
  2. Estimate batten count from desired spacing plus batten width.
  3. Reserve width for the battens.
  4. Divide the remaining open width evenly across the gaps.

FAQ

Does this include horizontal rails?

No. It estimates vertical batten count and spacing only.

Can I change the desired spacing?

Yes. Adjust desired spacing in the embedded calculator and the result will rebalance the layout.
