Log Diameter and Length Variations
Understanding how different log diameters and lengths affect the overall log count is essential. The following table illustrates the relationship:
| Diameter (inches) | Length (feet) | Approximate Volume (cubic feet) |
|---|---|---|
| 12 | 10 | 10.5 |
| 14 | 12 | 15.9 |
| 16 | 14 | 21.4 |
| 18 | 16 | 28.3 |
This table demonstrates how larger diameter and longer logs contribute to a greater volume, reducing the total number of logs needed for the project. It’s important to note these are estimations and the actual volume will depend on the specific log shape.
Log Volume Estimation Method
Accurate log volume estimation accounts for variations in shape and potential defects. A practical method involves using a formula that considers the average diameter and length of the log. A common approach is the following formula, where the volume is approximated as a cylinder:
Volume ≈ π
- (Diameter/2)^2
- Length
Where:
- Diameter is in inches.
- Length is in feet.
- Volume is in cubic feet.
This method offers a quick estimate. However, for high precision, professional log volume measurement tools are recommended.
Estimating the number of logs needed for a 20×20 cabin hinges on log size and the desired wall thickness.

Number of Logs Needed = (Total Area of Cabin / Log Area)
(1 + Waste Factor)
Where:
- Total Area of Cabin = 20 feet
– 20 feet = 400 square feet - Log Area = Area of a single log (calculated from log dimensions)
- Waste Factor = A percentage (typically 10-15%) to account for waste and potential errors.
Example: If the log area is 1 square foot and the waste factor is 15%, the calculation would be:
Number of Logs Needed = (400 sq ft / 1 sq ft)
– 1.15 = 460 logs
