Pattern details

Pattern Repeat

Your pattern repeats every 12.25 inches. Ensure your wall length is divisible by this or plan for partial boards at the ends.

Batten Overlap

With a 1" gap and 2.5" batten, you have0.75" overlap on each side of the board. Aim for at least 0.5" overlap.

Design Tip

Wider boards (e.g., 1x12) with narrow battens create a more rustic look. Narrower boards (e.g., 1x6) create a busier, more textured appearance.

How to Use

Step-by-step instructions
  1. 1Enter the total length of the wall (in inches).
  2. 2Enter the width of the boards (in inches).
  3. 3Enter the width of the battens (in inches).
  4. 4Enter the gap spacing between boards (in inches).
  5. 5The calculator will estimate the number of boards and battens.

Material Estimation

Estimates the number of boards based on the repeating pattern of board plus gap. Battens cover the gaps.
Count = Length / (Board Width + Gap)

Variables:

LengthTotal wall length
WidthWidth of one board
GapSpace between boards

Example

10ft Wall

Inputs:

Wall Length:120 inches
Board Width:11.25 inches (1x12)
Batten Width:2.5 inches
Gap:1 inch

Steps:

  1. 1.Unit Width = 11.25 + 1 = 12.25 inches
  2. 2.Count = 120 / 12.25 = 9.8
  3. 3.Round up to 10 boards.
Result:
10 Boards, 9 Battens
