"Measuring of Roundwood" as recommended by the Timber Measurement Council

Measuring log volume using top (small) end diameter measurement. Top measurement may be used on all tree species, regardless of diameter and length.

The top diameter is measured 10 cm from the top end of the log.
All diameter measurements are measured under the bark.

Formula used:
V = π ÷ 4 * L * Dt²
V = the log volume in cubic metres
L = length of the log in metres
Dt = the small end diameter measured 10 cm from the top end of the log

Using Small End Diameter

Length of Log m
Small end diameter cm


Log Volume


  1. enter the log length in metres
  2. top end diameter measured 10 cm in from the top end of the log


  1. the volume of log in cubic metres
