Log Weight Calculator

Estimate the weight of a log.

Diameter

Length

Wood density (lb/ft³)

Weight 0.2727

Volume 0.0055

Formula: weight = π (d/2/12)² × length × density

Step-by-step with your numbers:

1. Values used:

2. Diameter = 1

3. Length = 1

4. Wood density = 50 lb/ft³

6. Weight = 0.2727

7. Volume = 0.0055

Did we solve your problem today?

Estimate a log's weight from its size (a cylinder).

The math behind it

volume = π × radius² × length; weight = volume × density. Green wood ≈ 45–60 lb/ft³.

12 in × 8 ft green log → ~314 lb.

Green vs dry?

Fresh-cut logs are far heavier due to water content.
