How much does drywall weigh?
The weight of one sheet of drywall depends primarily on the type and the size. The manufacturer and other factors such as humidity level can also affect the weight. You can use the calculator below to estimate the total weight of drywall for a given project. This will help you determine whether your truck is able to carry the load. For a more detailed explanation of how to calculate the weight of drywall, you can read the information below.
USG, LaFarge, and Certain Teed are three large North American drywall manufacturers. According to material safety data sheets from USG, standard drywall weighs approximately 38lb/ft3. Lightweight drywall weighs about 28-30 lb/ft3. These three companies publish approximate weights for their products as follows:
|Brand||1/4 inch||3/8 inch||1/2 inch||5/8 inch|
|USG© / National Gympsum©||1.2||1.4||1.6||2.2|
|Certain Teed© Easi-Lite™||N/A||N/A||1.3||N/A|
To estimate the weight of drywall from different manufacturers we can normalize their published weights and use lb/ft3 as a baseline.
|1/2 inch Standard Drywall||Lbs/ft3|
|USG© / National Gympsum©||~38.4|
|Certain Teed© Easi-Lite&trade||~30.5|
The chart below shows the approximate weight of one sheet of 4' wide drywall of various lenghts from different manufacturers using both a lbs/ft3 and lbs/ft2 calculation.
Using lbs/ft3 calculations for 48” wide sheets
|Lbs/ft3||8 ft long||10 ft long||12 ft long||14 ft long|
Using lbs/ft2 calculations for 48” wide sheets
|Lbs/ft2||8 ft long||10 ft long||12 ft long||14 ft long|
It is difficult to determine the exact weight of a sheet of drywall because of the variables in manufacturing. Drywall may weigh more or less because of humidity levels durring or after manufacture, the manufacturing process or type of drywall used. It is possible to roughly estimate the weight based on published standards. A general estimation is usually sufficient for contractor needs.
