Enter the deck length (ft) and the deck width (ft) into the Deck Weight Limit Calculator. The calculator will evaluate the Deck Weight Limit. 

Deck Weight Limit Formula

The following two example problems outline the steps and information needed to calculate the Deck Weight Limit.

DWL = DL * DW * 100


  • DWL is the Deck Weight Limit (lbs)
  • DL is the deck length (ft) 
  • DW is the deck width (ft) 

To calculate deck weight limit, multiply the deck length and width, then multiply again by 100.

How to Calculate Deck Weight Limit?

The following steps outline how to calculate the Deck Weight Limit.

  1. First, determine the deck length (ft). 
  2. Next, determine the deck width (ft). 
  3. Next, gather the formula from above = DWL = DL * DW * 100.
  4. Finally, calculate the Deck Weight Limit.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

deck length (ft) = 12

deck width (ft) = 14

DWL = DL * DW * 100 = ?
