Lumber Dimensions. 2x4s are not actually 2 inches by 4 inches. When the board is first rough sawn from the log, it is a true 2×4, but the drying process and planing of the board reduce it to the finished 1.5×3. 5 size.

A **piece** of surfaced (sanded smooth) **2×4 lumber** actually measures 1½ inches thick and 3½ inches **wide**. In rough-cut condition, a **2×4** is slightly less than 2 inches thick and approximately 4 inches **wide**. When **wood** is milled from a rough to a smooth surface, it loses about ¼-inch from each of its four sides.

Also Know, is a 4×4 really 4 inches? Believe it or not, there **actually** is some rhyme and reason **for** why the actual measurements of dimensional lumber don’t match their names.

1x Board **Sizes** That means a 1 x 4 board is actually 3/4 inches by 3 1/2 inches.

When did a 2×4 get smaller?

Size standards, maximum moisture content, and nomenclature were agreed upon only as recently as 1964. The nominal **2×4** thus became the actual 1½ x 3½, imperceptibly, a fraction of an inch at a time. It was a 34 percent reduction in actual volume; as those in the trade would say, it’s “selling air.”

### How do you measure wood?

Board Foot: Rough sawn lumber is usually sold by the “board foot” (bd. ft.). A board foot is equal to a piece of wood 12 inches long x 12 inches wide and 1 inch thick, or 144 cubic inches. To figure the board foot measurement of a piece of wood, multiply the length x width x thickness in inches, then divide by 144.

### Why is a 2 by 4 smaller?

Two-by-fours are actually 1.5-by-3.5s. The same is true for most other wood cuts, which are all systematically smaller than their names would suggest. Here’s why. And moist wood—called “green lumber”—is prone to bending and warping.

Maybe you’ve noticed that lumber sizes are often misleading. The “nominal” cross-section dimensions of a piece of lumber, such as 2 X 4 or 1 X 6, are always somewhat larger than the actual, or dressed, dimensions. The reason is that dressed lumber has been surfaced or planed smooth on four sides (called S4S).
