How to Use the Log Weight Calculator

Using the log weight calculator is simple. Follow these steps to find out the total weight of a log:

Select the Wood Species
From the dropdown menu, choose the type of wood the log is made of. For example, if you’re calculating the weight of an oak log, select “Oak, Red” or the specific species from the list. This ensures the calculator uses the correct weight values.
Enter the Diameter of the Log
Measure the diameter of the log in inches at its widest point. Enter the number in the diameter field. The calculator supports diameters ranging from 10 to 36 inches, which is common for most logs.
Input the Length of the Log
Measure the length of the log in feet and enter it into the length field. You can input any value greater than 1 foot, whether it’s a single log section or the entire log length.
Click Calculate Log Weight
Once you’ve entered all the information, click the “Calculate Log Weight” button. The calculator will instantly provide the total weight of the log in pounds based on your inputs.
Review the Results
The results will show:
- The species of the wood.The diameter and length of the log.The total weight of the log in pounds.
Use this information to plan your hauling, woodworking, or project requirements that you might have.

Why Use the Log Weight Calculator

Using the log weight calculator can help you determine how many logs you will need for something as simple as a backyard bonfire or something as complex as building a log home, helping you decide on costs and maybe giving you an idea of how much money it will take to build.

Another great reason to find the weight of a log is for truckers hauling logs. In Canada and the United States, truck per axle weight is highly regulated, and drivers have maximum weight laws to follow per province or state. Knowing the weight of a log will determine if the driver is going to receive a fine or not. Being only 1,000 kgs overweight on their axles can sometimes result in fines of $2,000 or more. I’ve even heard of drivers receiving overweight fines in the tone of $20,000 in some rare cases.

Many logging companies use helicopters to move logs out of the bush because there’s no road access, and truckers can’t get into that area. Helicopters have a strict weight limit and need to make sure their weights are correct before moving logs. While our log weight calculator gives average weight numbers, it’s best to get the actual weight on-site as well because there are many variables when it comes to the weight of wood, including weather and the dampness of a log.

If you plan a woodworking project, knowing the weight of a log can help you decide what equipment you might need to move it around. A small tractor won’t be able to move a 10,000-pound log, so you’ll need bigger machines and heavier spec rigging for this type of project.

Final Thoughts

The biggest reason you need to know the weight of a log is to save money, whether you’re hauling the logs to the nearest mill or starting a woodworking project. The log weight calculator can help you determine what kind of machines you need, what kind of rigging you need, and several other factors. Using the log calculator will help you save time and money.
