How this tool works

Board feet equal thickness in inches × width in inches × length in feet ÷ 12, multiplied by board quantity.

Limits to know

Board feet measure nominal lumber volume: thickness in inches × width in inches × length in feet ÷ 12 × quantity. They do not predict dressed dimensions, usable yield, moisture, grading, kerf, waste, or price.
