Wood Weight Factors
The weight of lumber is determined by its density, which varies significantly between species and moisture content.
Nominal vs Actual Size:
This calculator automatically adjusts for actual lumber dimensions. For example, a "2x4" is actually 1.5" x 3.5".
Board Foot (BF):
A board foot is a unit of volume for lumber, equal to a board 12" long, 12" wide, and 1" thick (144 cubic inches).
