Calculate the Weight of Wood

Calculate the weight of kiln dried pine, green oak, and pressure treated wood with this free and easy online tool.

Use the drop downs to select a size for the lumber. The list contains the most popular sizes for wood. If it is not on the list, then it may be necessary to use another size and adjust it accordingly. For example, 4 x 6 lumber is not on the list, but you can simply choose 2 x 6 and double the value.

Next select a length in feet and inches. Finally select a type. The choices on the list are kiln dried pine, green oak, pressure treated above ground, and pressure treated below ground. The weight of the lumber is automatically returned in pounds.

Variations in the Weight of Wood

The weight of pine, green oak, and pressure treated can vary greatly from board to board. This calculator assumes that it has a fairly high moisture content.  Exposure to excessive moisture for tree sawn and engineered lumber will also temporarily increase the density (water log).

The beam in this photo is an examples of the type of lumber this calculator considers. It is a 2 ply 12″ laminated. It will weigh approximately 170 pounds.
