Decking, Fencing & Timber calculator
Board & Batten Calculator
Calculate batten count, balanced clear spacing and total batten length from wall width/height, batten width and target gap.
Calculate batten count, balanced clear spacing and total batten length from wall width/height, batten width and target gap. Enter the project measurements first, then replace any default material or performance value with data for the product you intend to use. Check board width and visual set-out carefully. A board-and-batten layout is visual as well as numerical. Set out the facade so end spaces and openings look intentional before ordering.
What you need to enter
The Board & Batten Calculator uses the following project information to calculate the result.
- Wall width
- Wall height
- Batten width
- Target clear gap
- Extra length allowance (%)
Calculator result
Batten count, equal spacing and total linear length
How the Board & Batten Calculator works
The Board & Batten Calculator estimates batten count, equal spacing and total linear length from this relationship: choose whole batten count around target gap, recalculate equal clear gaps, multiply count × wall height × allowance. Because the page is designed for board and batten linear material for a wall or facade, the calculation depends especially on board width and visual set-out. Metric and imperial entries are normalised before the arithmetic so equivalent measurements produce equivalent results.
Board & Batten Calculator worked example
Board & Batten Calculator example: on a 4.8 m wall using 45 mm battens and a target gap near 400 mm, the tool chooses a whole batten count, recalculates balanced equal gaps and multiplies the batten count by wall height for total linear length. The important sense-check is board width and visual set-out, because that can move the real requirement away from the neat theoretical result.
Important calculation assumptions
For board and batten linear material for a wall or facade, a board-and-batten layout is visual as well as numerical. Set out the facade so end spaces and openings look intentional before ordering.
Frequently asked questions
What should I write down before calculating with the Board & Batten Calculator?
The quality of the result starts with the inputs. Measure wall width and height, enter batten width and a target clear gap, then use the calculated equal spacing as a set-out starting point. They are used here to estimate board and batten linear material for a wall or facade.
What should I verify about board width and visual set-out before trusting the Board & Batten Calculator?
A board-and-batten layout is visual as well as numerical. Set out the facade so end spaces and openings look intentional before ordering. Treat the assumptions behind board width and visual set-out as project-specific in the Board & Batten Calculator.
How should I use the Board & Batten Calculator result to set out the wall?
For the Board & Batten Calculator, the numerical answer still needs a real-world check. Use the count and equal spacing to test the visual layout before cutting. Adjust the set-out around corners, windows and doors so end bays remain balanced.
