The weight of a 2x4 lumber board varies depending on the type of wood and its moisture content. Generally, a standard 2x4 made from pine or spruce weighs about 10 to 12 pounds per linear foot. Therefore, an 8-foot long 2x4 would weigh approximately 80 to 96 pounds. It's important to check specific wood species for more accurate weights.
The weight depends on the type of wood. Pine weighs less than oak.

Not enough information is given. We are only given two of the board's dimensions, and you haven't specified which dimensions those are. Presumably you mean thickness and width.Even with that, we would still need to know ~at least~ the length of the board and what material it is (pine? maple? something else altogether?). Even then, the answer could only be a very rough one, as there are many other factors that would need to be specified or guessed (the moisture of the wood, the positioning of the weight on the board, how the board is supported, the temperature, and so on).

The weight limit for a 2x2 pine board that is 3 feet long would depend on the grade and quality of the pine, as well as any additional supports or structures it is attached to. As a general guideline, a standard-grade pine board of this size may be able to support around 50-100 pounds evenly distributed, but it is always best to consult a structural engineer for specific weight limit calculations.
A board foot is a unit of volume equivalent to 144 cubic inches. To find tons, you would need to know the density of the particular wood that you are interested in. ==================================================== Boardfeet is based upon nominal dimensions. For example the nominal dimensions of a 2x4 is 2" x 4". It's actual dimension is closer to 1 1/2 inches x 3 1/2 inches. So there will be some error in the calculation if you are attempted to determine the weight of dimensional lumber. Southern Pine weights approximately 40 lbs per cubic foot. There are 1728 cubic inches in a cubic foot. There are 2000 lbs in a ton. therefore the weight of one board foot (conservatively because of the nominal dimensions) is: (40x144)/(1728x2000) tons per board foot. Sorry , don't have a calculator handy. Another way to do it is that there are about 12 board feet in a cubic foot. So a board foot would weight 40/12 lbs or 3.33 pounds. 3.33 pounds is 3.33/2000 tons. !! a lot easier!! (southern yellow pine) glenn
A 2 by 4 (lumber) will have a weight based on the density of the wood. Pine, fir, redwood, treated or untreated will have different densities.

Once it's kiln dried, yellow pine is one of the lighter woods. I wouldn,t think a 4x12x10' should weigh much more than 60 lbs. Maybe not that much. Sorry, but the above answer is incorrect. Actually the weight of dried southern yellow pine is around 3 lbs per board foot. A 4x12x10' contains 40 board feet and therefore weighs approximately 120 lbs. The above answer is conservative. The exact answer is yellow pine has a density of roughly 40lbs/ft^3. A 4x12 is actually 3.5"x11.25" = 39.38in^2. Therefore for a 10ft section: (40lb/ft^3) x ((39.38in^2)/144) x (10') = 109.4 lbs.
It depends upon the species as weights can very greatly, even among softwoods, such as pine, fir, or especially cedar or cypress. Additionally, moisture content and treatments can impact the finished weight. Southern Yellow pine, fresh cut varys from 36 lbs/cubic foot (20% moisture) to 53 lbs/cubic foot for fresh cut (green). Pressure treating also adds additional moisture, thus weight. If the lumber is from a lumber yard, not treated, kiln dried, dimensional pine lumber would typically weigh 37 lbs / cubic foot, so a 16' 2 x 4, actually 16' 1.5" x 3.5" would be: 1.5 X 3.5 X 192 = 1008 cubic inches 1728 cubic inches in a cubic foot so: 1008 / 1728 = 0. 583 cubic feet weight of pine = 37 lbs/cubic foot X 0.583 = 21.58 lbs for a 16' 2" x 4". or 1 1/2" = 0.125 cubic feet 3 1/2" = 0.292 cubic feet .125 X .292 X 16 = 0.583
The weight depends on the type of wood. Pine weighs less than oak.

Im building a bench. Im using 2"x10" pine. Is 5' between braces strong enough? It depends on how many boards your are putting on your bench. To give you an idea, I ran through some quick numbers for you. @ 5'. one 2" x 10" x ?? pine board assuming a 400lb load (2-3 people) you will have deflection of .42" PER board which is fine. Less than 1/2 inch. @ 4' your deflection is reduced to .22" PER board which is even better. You really shouldn't have a problem at 5', unless a 400lb guy jumps on the middle of your bench. The maximum weight it will take in the middle before fracture is 688 lb @ 5'/brace and 860 @ 4'...and keep in mind this is per board so if you have two....you should be fine. This is as long as it is standard pine. .
try 2 put both foot on it.
