![]() ![]() In some of the larger timbers, like the 2x8's, 2x10's, and 2x12's, we also stock longer lengths (some up to 24'), since these are often used as rafters or for floor joists, where longer is usually better. The length of the boards is generally exactly what you order, though we usually only stock pieces of even lengths.

It is also important to note that if the. This is because wood is anistrophic, meaning that the wood's properties will change depending on the grain direction. Boards will shrink width-wise versus length-wise because of the direction of the grain. In this case, the planing is necessary for a smoother surface, so that the board could be used for interior applications. Actual measurements are the actual final size of the lumber after it has been dried and planed. The following is a table describing common lumber sizes, and their actual sizes and weights (assuming the wood weighs 35 pcf). During the finishing phase (includes drying and planing the board) the 2x4 has been reduced to 1.5' x 3.5'. A 1圆, for example, actually measures 3/4" x 5 1/2". Sawn lumber is not the actual size that youve grown up hearing. In the United States, softwood lumber is governed by the National Institute of Standards American Softwood Lumber Standard (PS 20). Product dimensions will vary depending on moisture content. Actual size: dimensions at time of manufacture. 3 grade where larger knots and other characteristics are not a concern. How big is a 1x2 When the board is first rough sawn from the log, it is a true 2x4, but the drying process and planing of the board reduce it to the finished 1.5x3. CA Residents: Prop 65 Warning(s) Prop 65 WARNING(S) Show All. Species may vary between Pine, Spruce and Fir. That means a 1 x 4 board is actually 3/4 inches by 3 1/2 inches. Instead, a 2x4 is really only 1 1/2" by 3 1/2". Softwood lumber is generally used for framing walls and floors. 1x Board Sizes These boards lose 1/4 inch in thickness and 1/2 inch in width before leaving the mill. Because of this extra milling, a 2x4 no longer measures a full 2 inches by four inches. Now, most timber is milled and planed to give it a little more of a finished look, and a little more of a consistent size and profile. In the past, when a timber was called a 2x4, it actually measured 2 inches by 4 inches. An important thing to know is that with most any dimensional lumber, there is a difference between what the board is called, and what it truly measures. What we stock is a framing grade of spruce in an assortment of sizes and lengths. "Dimensional" lumber is the general name for framing lumber.
