Frequently asked questions
How much does a 1/2" sheet of drywall weigh?
A 4x8 sheet of 1/2" standard drywall weighs about 51.2 lb. A 4x12 sheet of the same board is about 76.8 lb. Lightweight 1/2" 4x8 sheets are about 38.4 lb. The calculator uses 1.6 lb/ft² for standard 1/2" and 1.2 lb/ft² for lightweight.
How much does a 5/8" sheet of drywall weigh?
A 4x8 sheet of 5/8" standard drywall weighs about 70.4 lb. A 4x12 sheet is about 105.6 lb. Lightweight 5/8" 4x8 sheets are about 52.8 lb. The calculator uses 2.2 lb/ft² for standard 5/8" and 1.7 lb/ft² for lightweight.
How much does a 4x8 sheet of drywall weigh vs a 4x12?
A 4x8 sheet is 32 ft² and a 4x12 is 48 ft², so the longer sheet is 50% heavier at the same thickness and type. For 1/2" standard board that is about 51.2 lb (4x8) vs 76.8 lb (4x12). For 5/8" standard it is about 70.4 lb vs 105.6 lb.
How much lighter is lightweight drywall than standard?
On the thicknesses the calculator supports, lightweight board uses a lower lb/ft² rate: 1.2 vs 1.6 for 1/2", and 1.7 vs 2.2 for 5/8". A 4x8 1/2" sheet drops from about 51.2 lb (standard) to 38.4 lb (lightweight). A 4x8 5/8" sheet drops from about 70.4 lb to 52.8 lb.
How do I estimate the total weight of drywall for a job?
Multiply the per-sheet weight by the number of sheets. Ten 4x8 sheets of 1/2" standard drywall are about 512 lb. Use this calculator for per-sheet and job totals (standard or lightweight). If you still need a sheet count, start with the sheet-count calculator, then come back here.
