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. Drag and drop countries around the map to compare their relative size. That means a 2x10 is actually 1 1/2 inch in thickness by 9 1/4 inches. The larger 2x boards (2x8, 2x10, etc.) lose 3/4 inch in width. That means a 2 x 4 board is actually 1-1/2 inches by 3-1/2 inches. And there you go, a 14-foot Ponderosa pine 2×10 weighs 37.8 pounds. If your 2×10 is 14 feet long, multiply 14 by 2.7 pounds to get 37.8 pounds. Step 6: Multiply by the length of the 2×10. So 2.7 pounds is the weight per foot of a 2×10 made from Ponderosa pine. The length of the boards is generally exactly what you order, though we usually only stock pieces of even lengths. Commercial softwood lumber dimension chart - nominal and actual sizes. 2x4 and 2圆 boards lose 1/2 inch in thickness and 1/2 inch in width before leaving the mill. We’d round this up to 2.7 pounds to be practical. In this case, the planing is necessary for a smoother surface, so that the board could be used for interior applications. A 1圆, for example, actually measures 3/4" x 5 1/2". Instead, a 2x4 is really only 1 1/2" by 3 1/2".

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.
