About this calculator
Wood Density and Water
The weight of a log is determined by two main factors: the density of the wood fibers itself and the amount of water (sap) it contains. 'Green' wood can be nearly twice as heavy as seasoned wood because it is saturated with water. This calculator is essential for safe hauling and preventing equipment damage.

Pro Tips
Safety First: Never exceed the weight limit of your trailer or winch. A single large oak log can weigh over 2,000 lbs.
Center Diameter: Since logs are tapered, measure the diameter at the midpoint (the average of the two ends) for the most accurate volume.
Fuel Efficiency: Seasoning wood (letting it dry) not only makes it lighter to transport but also significantly increases its BTU value when used as firewood.
Species Variation: Even within the same species, density can vary based on the tree's growth rate and the region's climate.

Fun Facts
"Freshly cut oak is so dense and water-saturated that it can actually sink in water."
"Heartwood (the center of the log) is usually denser and more decay-resistant than the outer sapwood."
"Lignin is the organic 'glue' that gives wood its strength and allows trees to grow so tall."
