How to Use a Construction Materials Calculator

  • Coverage Area Length – First you need to carefully measure the length of your project’s coverage area. The calculator requires this measurement to be taken in Feet (ft). Double check your measurement, then enter that number.
  • Coverage Area Width – Next, enter the width of your coverage area into the calculator. Just like the length, this number also needs to be in Feet.
  • Coverage Area Depth – The final number the calculator will need, is the depth. However, this number will need to be supplied in Inches (In). Enter this number into the 3rd box and your calculation will then be complete.
