Enter the total square footage of drywall (ft^2) and the drywall thickness (in) into the Drywall Weight Calculator. The calculator will evaluate the Drywall Weight. 

Drywall Weight Formula

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

DW = A * T/12 * 38.205

Variables:

  • DW is the Drywall Weight (lbs)
  • A is the total square footage of drywall (ft^2) 
  • T is the drywall thickness (in) 

How to Calculate Drywall Weight?

The following steps outline how to calculate the Drywall Weight.


  1. First, determine the total square footage of drywall (ft^2). 
  2. Next, determine the drywall thickness (in). 
  3. Next, gather the formula from above = DW = A * T/12 * 38.205.
  4. Finally, calculate the Drywall 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.

total square footage of drywall (ft^2) = 30

drywall thickness (in) = .375

DW = A * T/12 * 38.205 = ?
