What is Deck Weight Limit Calculator?
The Deck Weight Limit Calculator is used to determine the maximum weight that a deck can safely support. It is typically used by homeowners, contractors, and builders to ensure that a deck can support people and objects without collapsing.
DWL = DL x DW x 100
Where:
- DWL is the Deck Weight Limit in pounds (lbs)
- DL is the length of the deck in feet (ft)
- DW is the width of the deck in feet (ft)
The formula assumes a uniformly distributed load (i.e., weight is evenly distributed across the deck) and that the deck is designed to support a minimum live load of 40 pounds per square foot (psf).
The formula works by multiplying the deck length and width (in feet) by 100 and the result gives the maximum weight that the deck can safely hold (in pounds). For example, if a deck is 12 feet long and 10 feet wide, the Deck Weight Limit would be:
DWL = 12 ft x 10 ft x 100
= 12,000 lbs
The Deck Weight Limit Calculator provides an estimate, not a substitute for professional advice, and other factors such as the deck’s design, materials, and intended use can also affect its weight capacity.
