Log Weight Calculator

What Is a Log Weight Calculator?

A log weight calculator estimates the weight of logs and lumber using green wood density and dimensions. Select a tree species, enter tapered log diameters or board size, and get per-piece and total weight for hauling, milling, and firewood planning.

How Log Weight Is Calculated

Weight equals green density times volume:

$$\text{weight} = \rho_{\text{green}} \times v$$

For tapered logs, Huber's formula uses mid-section diameter:

$$v = L \times \frac{\pi \times d_m^2}{4}$$

where $d_m = (d_s + d_l) / 2$, $d_s$ is the small-end diameter, and $d_l$ is the large-end diameter.

For similar material weight estimates, see the Concrete Weight Calculator and Weight Converter.

Frequently Asked Questions

What is green wood weight?

Green weight is the weight of freshly cut wood that still holds most of its moisture. It is heavier than kiln-dried or seasoned wood of the same volume.

What is Huber's formula for logs?

Huber's formula estimates log volume using the diameter at the midpoint of the log length. Mid diameter equals the average of the small-end and large-end diameters.

How do I measure log diameter?

Measure the smallest diameter near the top end and the largest diameter near the base. The calculator averages them for the mid-section diameter used in volume estimation.

How much does an oak log weigh?

Weight depends on species, dimensions, and moisture. English oak green density is about 52 lb/ft³. An 8-foot log 12 to 16 inches in diameter can weigh several hundred pounds.

Can a pickup truck carry a full oak log?

A typical pickup handles about 1,000 lb payload. Dense hardwood logs exceed that quickly. Use this calculator to check total weight before loading.
