What is Dimensional Lumber?

Dimensional lumber is simply lumber that is produced with standardized dimensions. Standard dimensions, such as 2″ x 4″ or 2″ x 6″, allow for a multitude of efficiencies in construction.

Subcategories of dimensional lumber include appearance framing lumber, beams, joists, light framing lumber, planks, posts, stringers, structural light framing lumber, studs, and timbers. Our lumber weight chart below covers all of these.

Dimensional lumber is used for wall framing, rafters, and many other building components. Lumber weight is an important factor in various structural design considerations.

A stack of 2x10 boards. This is dimensional lumber. Weight for each board is about 39 lbs.

How Much Does Lumber Weigh?

The weight of lumber depends on the size of the board, the moisture content of the wood, and which tree species the lumber was made from.

Green lumber has a higher moisture content than air-dried lumber, and air-dried lumber has a higher moisture content than oven-dried lumber.

Common construction lumber boards with the exact same dimensions but produced from different tree species may vary as much as 50% in weight, even with the same moisture content percentage.

An air-dried 2×4 x 8-foot-long lumber board made out of Douglas Fir weighs about 10 pounds. A board with the same dimensions made out of Sitka Spruce only weighs around 8 pounds.

Almost all lumber used for construction in the U.S. is made from spruce, pine, and fir, so our chart has weights for lumber made from all three.

Green or Oven-Dry Lumber Weights

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.

Nominal vs. Actual Lumber Dimensions

For an explanation of the difference between nominal lumber dimensions and actual dimensions, see our Lumber Dimensions Table.

About Our Lumber Weight Chart

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 air-dried weight of lumber produced from three commonly used tree species: Sitka Spruce, Douglas Fir, and Southern Yellow Pine.

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.

You can 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.

Note: Longleaf Pine is a very heavy pine. See weights for other pines here. Another good page to look at to compare the weights of different kinds of wood is Weight of a 2×4 by Wood Type and Length.
