How is Log Weight Calculated?
The Log Weight Calculator uses the formula for the volume of a cylinder (V = πr²h) combined with the density of the selected wood species. The total weight is simply the Volume multiplied by the Density.
This tool is essential for anyone needing to transport, lift, or process logs, as underestimating the weight can be a significant safety hazard. It provides two key figures: Green Weight (for freshly felled trees with high moisture content) and Dry Weight (for seasoned wood), which is considerably lighter.
Common Wood Species & Their Properties
| Wood Species | Avg. Dry Density (lb/ft³) | Common Uses | Hardness |
|---|---|---|---|
| Pine (Eastern White) | 25 | Construction lumber, furniture, carving | Soft |
| Oak (Red) | 44 | Flooring, furniture, cabinetry, barrels | Hard |
| Maple (Sugar) | 44 | Furniture, flooring, butcher blocks | Very Hard |
| Walnut (Black) | 38 | High-end furniture, gunstocks, veneer | Hard |
How to Use the Log Weight Calculator
- Log Diameter: Enter the average diameter of the log (measure at the center).
- Log Length: Input the total length of the log.
- Wood Species: Select the type of wood. Density varies greatly between species and determines the final weight.
- Unit System: Choose between Imperial (inches, feet) and Metric (cm, meters) units.
- Calculate: Get an instant estimate for both the green (wet) and seasoned (dry) weight of the log.

Frequently Asked Questions (FAQ)
Does this calculation account for the log tapering?
No, this calculator assumes the log is a perfect cylinder. For the most accurate result, measure the diameter at the middle of the log to get an average.
What if my wood species is not on the list?
The list contains common woods, but thousands of species exist. If yours is not listed, you can use an online resource to find the green and dry density of your wood and select the species with the most similar density from our list for a rough estimate.
