Log Weight Calculator
This log weight calculator will help you estimate the weight of a freshly cut tree using its "green" density and volume.

What Log Weight Calculator does
This log weight calculator estimates the weight of freshly cut timber by combining user-entered dimensions with species-specific green density values. The output provides both the weight for a single log and a total weight if multiple pieces are needed, supporting material procurement and logistics planning for construction and woodworking projects. The tool covers a broad range of common North American species, from pine and oak to more specialized hardwoods, and allows users to input a custom wood density if their species is not listed. Results are displayed clearly, showing volume, weight per piece, and total weight based on quantity entered.
How to use the Omni Calculator Log Weight Calculator
- 1
Select the wood species from the dropdown list or enter a custom density value
- 2
Input the diameter at the smaller end, diameter at the larger end, and diameter at mid-section of the log
- 3
Enter the length of the log and the quantity of pieces needed
- 4
View the calculated volume, weight per piece, and total weight in the output fields
Best for
Contractors, builders, and DIY enthusiasts who need quick, accurate estimates for log weight to plan material procurement and logistics for construction or woodworking projects.
Limitations
- Estimates are based on green density and may vary with actual moisture content
- Requires manual entry of custom density if species is not in the list
- No unit switching available; dimensions must be entered in the specified units
Log Weight Calculator FAQ
- Can I calculate the weight of a log if I only know its diameter and length?
- The tool uses green density values specific to each wood species; for the most accurate result, select the species that matches your wood or enter a custom density if the species is not listed.
- How does the calculator handle multiple logs?
- Users can enter a quantity value, and the calculator will display both the weight per piece and the total weight for all specified pieces.
- Is the weight calculation adjusted for dry or seasoned wood?
- No, the calculator estimates weight using green (freshly cut) density; for seasoned or dry wood, the actual weight will be lower than the calculated result.
