Log Weight Calculator
Calculate log weight using Huber's formula with wood species density and dimensions
Calculate Log Weight
Green weight density: 62 lbs/ft³
Wood Weight Results
Formula: Weight = Density × Volume
Huber's Volume: V = L × π × dm² / 4 = 0.00 × π × 0.00² / 4
Density: 62 lbs/ft³ (oak white green weight)
Load Analysis
Example Calculation
English Oak Log Example
Species: English Oak (52 lbs/ft³ green weight)
Smaller diameter: 15 inches
Larger diameter: 20 inches
Length: 3.3 feet (100 cm)
Quantity: 3 logs for pickup truck
Calculation Steps
Mid-section diameter = (15 + 20) / 2 = 17.5 inches = 1.458 ft
Volume = 3.3 × π × 1.458² / 4 = 5.51 ft³
Weight per log = 5.51 × 52 = 287 lbs
Total weight (3 logs) = 860 lbs ✅ Fits in pickup truck
Common Wood Densities
Measurement Tips
Measure diameter at both ends and calculate average for mid-section
Use measuring tape across the widest part of each end
Measure length along the centerline of the log
Account for any defects or hollow sections
Safety & Transport
Check vehicle weight capacity before loading
Green wood is significantly heavier than dried wood
Use proper rigging and tie-down equipment
Consider road weight limits for commercial transport
Use mechanical lifting equipment for heavy logs
Understanding Log Weight Calculations
What Affects Wood Weight?
Log weight depends on three main factors: wood species (density), volume, and moisture content. This calculator uses "green weight" densities, which represent freshly cut wood with high moisture content.
Why Calculate Log Weight?
- •Transportation planning and vehicle selection
- •Equipment capacity and safety considerations
- •Construction load calculations
- •Lumber purchasing and cost estimation
Huber's Formula
Volume = L × π × dm² / 4
dm = (ds + dl) / 2
Weight = Volume × Density
- L: Length of the log
- dm: Diameter at mid-section
- ds: Diameter at smaller end
- dl: Diameter at larger end
- Density: Green weight per cubic foot
Note: Green wood contains 50-150% moisture content, making it much heavier than kiln-dried lumber.
Wood Species Categories
Heavy Hardwoods
Oak (62-76 lbs/ft³), Hickory (64 lbs/ft³), and Maple (45-56 lbs/ft³) are dense hardwoods requiring heavy-duty transport.
Medium Density
Pine species (36-58 lbs/ft³) and Fir (29-47 lbs/ft³) offer good strength-to-weight ratios for construction.
Light Softwoods
Cedar (28-45 lbs/ft³) and Spruce (32-34 lbs/ft³) are lightweight options ideal for projects requiring easy handling.
