How to Estimate Door Weights
Figures below represent average pounds per square foot.
1-3/8″ DOOR THICKNESS
1-3/4″ DOOR THICKNESS
2″ DOOR THICKNESS
To calculate your door weight multiply the size of your door (in square feet) times the number in the chart above (pounds per square feet). The result is your door weight in pounds.
For example if you have a 1-3/4″ thick door that is 8’0″ by 3’2″ and made out of oak, you would calculate the square inches of the door (96 x 38 = 3648) and divide by 144 to get the square footage (3648/144 = 25.33). To calculate the door weight multiply the square footage times the pounds per square foot for oak (25.33 x 7 = 177.31 lbs). Keep in mind that this is an estimate and does not include any hardware that you are going to have on the door.
