Enter the snow area (ft2) and the snow depth (ft) into the Snow Load Weight Calculator. The calculator will evaluate the Snow Load Weight. 

Snow Load Weight Formula

The following two example problems outline the steps and information needed to calculate the Snow Load Weight.

SW = A * D * 4.5


  • SW is the Snow Load Weight (lb)
  • A is the snow area (ft2) 
  • D is the snow depth (ft) 

How to Calculate Snow Load Weight?

The following steps outline how to calculate the Snow Load Weight.

  1. First, determine the snow area (ft2). 
  2. Next, determine the snow depth (ft). 
  3. Next, gather the formula from above = SW = A * D * 4.5.
  4. Finally, calculate the Snow Load Weight.
  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.

snow area (ft2) = 100

snow depth (ft) = 3

SW = A * D * 4.5 = ?
