Board and Batten Calculator
The board and batten calculator is a one-of-a-kind tool that helps you determine not only the material needed but also the number of boards, battens, and rows you need for your perfect-looking wall siding.
Boards needed2320.48 to cover it, plus 10% waste
Linear length230 ft70.104 m of board in total
Each board covers9.375 sq ft11.25 in effective width × 10 ft
Area to cover192 sq ft
Rows of board13across 12 ft
Board feet215.63figured at 1 in nominal thickness
The method
boards = covered width ÷ board coverage, plus waste
Face width, not nominal width
A “6-inch” deck board is 5½ inches across, and if you leave a ¼-inch drainage gap each board accounts for 5¾ inches of deck. Working from the nominal 6 inches would leave you several boards short over a large deck.
For cladding the same logic applies to the exposure: lapped siding covers less than its width because each course overlaps the one below.
