Log Weight Calculator
Calculate log weight and board feet for timber handling
Our log weight calculator helps you determine the weight and board feet of logs. Follow these steps:
- Enter the log length in feet
- Input the log diameter in inches
- Select the wood density (or use default)
- Specify the moisture content percentage
The calculator will provide log volume, board feet, green weight, dry weight, and current weight based on moisture content.
Common wood types and their green densities (lbs per cubic foot):
- Pine (Southern Yellow): 50-55 lbs/cu ft
- Oak (Red/White): 60-65 lbs/cu ft
- Maple (Hard): 55-60 lbs/cu ft
- Cedar: 35-40 lbs/cu ft
- Douglas Fir: 45-50 lbs/cu ft
- Poplar: 40-45 lbs/cu ft
Note: These densities are approximate and can vary based on growing conditions and specific species.
Typical moisture content levels in wood:
- Green Wood: 50-200% moisture content
- Air-Dried Wood: 15-19% moisture content
- Kiln-Dried Wood: 6-8% moisture content
- Furniture-Grade Wood: 6-8% moisture content
- Construction Lumber: 12-15% moisture content
Moisture content significantly affects wood weight and should be considered when planning transport or structural applications.
- Use appropriate lifting equipment for heavy logs
- Consider mechanical advantages when moving logs
- Wear proper safety gear (gloves, steel-toed boots)
- Check for stability before cutting or moving
- Be aware of potential rolling hazards
- Use proper chainsaw safety techniques
- Consider weather conditions when handling
- Have a clear plan for log movement
What is a board foot?
A board foot is a unit of volume equal to 144 cubic inches (12"x12"x1"). The Doyle Log Rule is commonly used to estimate board feet in logs, though actual yield may vary.
Why does moisture content matter?
Moisture content significantly affects wood weight and properties. Green wood can weigh more than twice as much as dried wood, impacting handling requirements and structural calculations.
How accurate are the weight calculations?
Calculations are estimates based on average densities and perfect cylindrical logs. Actual weights may vary due to log shape, defects, and specific growing conditions.
