Wood Species Weight Calculator

How It Works

Wood density varies enormously by species. Balsa weighs about 9 lbs/ft³ while lignum vitae is 80+ lbs/ft³. Moisture content dramatically affects weight — freshly cut "green" wood at 80% MC weighs nearly twice as much as kiln-dried wood at 8% MC. Standard kiln-dried lumber is 6-8% MC, while air-dried is typically 12-15%. A board foot is 144 cubic inches (1" × 12" × 12") and is the standard lumber measurement. Knowing wood weight matters for shipping costs, shelf load calculations, and furniture portability.
