Weight of Dimensional Lumber

Last updated July 18, 2020
The following table provides the approximate weight (dead load, self-weight) per linear foot of the various sizes of dimensional lumber (also called “structural lumber” or “finished lumber”) used in building construction in the US. The table provides the weight of lumber produced from three commonly used tree species: Sitka Spruce, Douglas Fir, and Southern Yellow Pine.
For help figuring out the weight of green or oven-dry lumber, to read more about how these weights are calculated, or to see an extensive list of the weights of other types of wood, see "Weights of Various Woods Grown in the United States" from the Forest Products Laboratory, United States Forest Service.
For an explanation of the difference between nominal lumber dimensions and actual dimensions, see our Lumber Dimensions Table.
The values given in the table are meant to provide a general idea of typical lumber weights, and should not be used if precise values are needed for critical engineering calculations. When precision is necessary, always refer to the specification sheet for the actual, specific product you intend to use, or contact the technical department of the producer.
See dimensional lumber at the Home Depot.* The approximate weights of the actual pieces of lumber for sale are often given in the product descriptions, so this can be a pretty good resource for calculating lumber weights. Home Depot will also deliver lumber to your home, by the way.
