Quick Reference: Weight of Dimensional Lumber
The following table provides the approximate weight per linear foot of the various sizes of dimensional, or structural, lumber used in building construction in North America. 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.
