Enter the length of the shingle (ft) and the width of the shingle (ft) into the Shingle Weight Calculator. The calculator will evaluate the Shingle Weight. 

Shingle Weight Formula

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

SHW = LS * WS * 2.75

Variables:

  • SHW is the Shingle Weight (lbs)
  • LS is the length of the shingle (ft) 
  • WS is the width of the shingle (ft) 

How to Calculate Shingle Weight?

The following steps outline how to calculate the Shingle Weight.


  1. First, determine the length of the shingle (ft). 
  2. Next, determine the width of the shingle (ft). 
  3. Next, gather the formula from above = SHW = LS * WS * 2.75.
  4. Finally, calculate the Shingle 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.

length of the shingle (ft) = 40

width of the shingle (ft) = 20

SHW = LS * WS * 2.75 = ?
