How do you calculate deck load capacity?
If your deck is built to code, then it is designed to hold a minimum of 50 pounds per square foot, of which ⅘ of that total is the “live” load. Therefore, a deck of 120 square feet multiplied by 50 shows that your deck can hold 6000 pounds, including the structure.

What is the load on a deck?

What are the dimensions of load area 2 on a deck?
The dimensions of load area 2 are 6’x3.25′ and equals 19.5 square feet. And since the deck is symmetrical, the load areas 5 and 6 on the opposite side of the deck are identical. This leaves only the load areas 3 and 4 in the center area of the deck to be determined.
