How do you calculate quantity of timber?

To calculate the quantity of timber, you typically measure the dimensions of the timber pieces in feet or meters, including length, width, and thickness. For standard lumber, you can use the formula: Volume (cubic feet) = Length (feet) × Width (inches) × Thickness (inches) ÷ 12. For larger logs, the Scribner or Doyle log rules can be applied to estimate board feet. Always ensure to account for any waste or defects when determining the total quantity needed.
