Wood Beam Weight Calculator

Summary

Enter beam dimensions and select a wood species to instantly calculate the total weight of a rectangular lumber beam.

How it works

1. Enter the beam width (in inches or millimeters) using the unit toggle.
2. Enter the beam height (depth of the cross-section).
3. Enter the beam length.
4. Select a wood species from the dropdown to apply its standard green or dry density.
5. The calculator multiplies cross-section area by length to get volume, then multiplies by density to return the weight in lb and kg.

Use cases

• Estimate structural lumber weight for load calculations in construction projects.
• Determine shipping weight of custom-milled timber orders.
• Plan crane or lift capacity for heavy timber framing.
• Compare beam weight across species to optimize material selection.
• Calculate dead load contribution of wood members for engineering analysis.
• Verify material takeoffs for cost and logistics estimates.
