Timber Scaling (Wood Measurement)

Timber Scaling is defined as the act of measuring timber to determine its volume or mass. The procedures follow clearly defined methodologies as outlined in the Provincial Timber Scaling Manual PDF Icon (5.31 MB).

Information and data collected from timber scaling may be used to:

  • determine wage payments in commercial timber transactions;
  • determine wood volumes for Royalty payments;
  • verify annual harvest as calculated by the allowable annual cut (AAC) growth models;
  • monitor inventory control, or
  • perform statistical analysis.

Timber Scaling Certificate

In Newfoundland and Labrador, a person must first obtain a Timber Scaling Certificate in order to legally measure timber. To become a certified scaler, you must successfully complete a Provincial Timber Scaling Training Course and be certified by the Timber Scaler’s Board.  The Timber Scaler’s Board is responsible for outlining scaling methods and requirements within the Province.  Exams are administered throughout the Province, on an as needed basis, by the Chief Scaler.   A Timber Scaling Certificate is valid for one year and expires on March 31 of each year. A scaler is responsible to renew the scaling certificate yearly by completing an annual return showing the volume of timber scaled during the certification period.  A scaler must measure a minimum volume of each form of timber calculated for a three year period to retain the right to scale that product. Re-fresher exams will be offered to all scalers who have not met the volume requirement or have let their licenses lapse.


The annual fee for a Timber Scaling Certificate is $10.
