Lumber Weight Calculator
Weight of any board by species and size — dry or fresh. Free.
Enter species, thickness, width, length and quantity. The calculator uses average density values per species to estimate board and total weight — useful for shipping, loading and structure checks.

FAQ
How accurate are the weights?
Densities are species averages; individual boards vary with grain, moisture and origin. Expect ±10–15% — good for handling and transport planning, not for precise structural loads.
Why does fresh wood weigh more?
Freshly cut (green) timber can hold 50–100% additional water weight versus kiln-dried lumber. The calculator applies a +50% factor as a practical middle value.
Can I add MDF and plywood?
Yes, engineered boards are in the species list with typical densities. For mixed panels, calculate each type separately.
