Estimate timber value from board feet (Doyle rule).

Diameter (DBH)

Merchantable 16-ft logs

Price per board foot ($)

Board feet (Doyle) (BF) 24.5

Estimated value ($) 12.25

Formula: BF = ((DBH − 4) ÷ 4)² × number of 16-ft logs

Step-by-step with your numbers:

1. Values used:

2. Diameter (DBH) = 18

3. Merchantable 16-ft logs = 2

4. Price per board foot = 0.5 $

6. Board feet (Doyle) = 24.5BF

7. Estimated value = 12.25$

Estimate a standing tree's timber volume and value using the Doyle log rule.

The math behind it

Doyle board feet = ((DBH − 4) ÷ 4)² × number of merchantable 16-ft logs; value = board feet × price per BF.

18 in DBH, two 16-ft logs at $0.50 → 24.5 BF (~$12.25).
