In general, a 2×4 can hold a horizontal load of around **20 to 40 pounds per linear foot** if the weight is evenly distributed. If the weight is centered between the span, that number could drop to 20 pounds total or less for longer 2x4s. Other factors can increase the weight that a 2×4 can support as well.

## How much weight can a 2×4 hold or support horizontally?

## How much force does it take to break a 2×4?

While it is hard to determine the breaking strength of 2x4s, the primary factor is the direction of the wood. Against the grain, as the wood lays flat, the amount that the 2×4 can withstand before breaking is usually **20 to 40 pounds per linear foot** as long as this weight is evenly distributed.

## How can I make my 2×4 stronger?
