Drywall Estimator Calculator – How It Works

The drywall estimator calculator finds the square foot of the wall you are drywalling. For example, if a wall is 10′ long and 12′ wide – the drywall estimator calculator multiplies the two to come up with 120 square ft for that wall. Next, it will divide the total square feet by the total square feet of a sheet of drywall. To make this a bit more efficient and give you options, I’ve included 4×8, 4×10, and 4×12 sheets of drywall. It’s up to you which size drywall sheet you would like to use.
