WOOD WEIGHT REFERENCE
GENERAL WOOD WEIGHTS
(See FIGURE 9.1)
• This chart is for reference only. The true weight of a log can change due to many factors
including, but not limited to: moisture content, age, branches, external debris, wood species,
hardwood content & variations in diameter.
• For calculating the general weight of a log use the following FIGURE 9.1 & formula:
– Overall Weight = Length (ft) x Weight per foot (lbs)
– Example: A 1 ft long Apple Log that is 16 inches in Diameter:
• 1 (ft) x 77 (lbs) = 77 lb Log
• Utilize the Notes Page 19 to write out log weight calculations.
