Lumber Weight Calculator

Start with species, actual dimensions, and piece count. Open advanced options for board-foot input, custom density, moisture, treatment, or output units.

Moisture 12% dry reference Treatment Untreated Units lb / lb-ft3
Choose the closest species. Select custom density if you have a supplier or lab density value.
Actual thickness, not nominal. A nominal 2× board is usually 1.5 inches thick.
Actual milled width. For example, a nominal 2×10 is about 9.25 inches wide.
Length of one piece in feet.
How many identical pieces are included in the total.
Advanced options
Volume Board-foot mode available Moisture Editable Units lb or kg
Use dimensions for identical boards, or board feet when your invoice already lists total BF.
Used only when Custom density is selected. Enter density in pounds per cubic foot.
Board-feet mode only. Enter the total board feet for the lot, not per-piece BF.
12% is a common dry reference; green lumber can be far higher.
Pressure-treated adds a broad retained-water/chemical allowance; other choices document condition without changing the entered moisture.
Choose pounds or kilograms for weight outputs.
Choose the density display unit.
