The weight of a plywood sheet equals its volume × density. Volume is length × width × thickness. Density varies by material:
| Material | Density (kg/m³) | Density (lb/ft³) |
|---|---|---|
| Pine / SPF | 500 | 31.2 |
| Douglas Fir | 530 | 33.1 |
| OSB | 650 | 40.6 |
| Plywood (generic) | 700 | 43.7 |
| Particleboard | 700 | 43.7 |
| Oak | 720 | 44.9 |
| Maple | 750 | 46.8 |
| MDF | 760 | 47.4 |
Common plywood sheet weights
| Sheet | Thickness | Weight (generic plywood) |
|---|---|---|
| 4×8 (48″×96″) | 1/4″ | ~20 lb (9 kg) |
| 4×8 (48″×96″) | 1/2″ | ~40 lb (18 kg) |
| 4×8 (48″×96″) | 3/4″ | ~60 lb (27 kg) |
| 4×8 (48″×96″) | 1″ | ~80 lb (36 kg) |
| 4×8 MDF | 3/4″ | ~65 lb (29 kg) |
| 4×10 (48″×120″) | 3/4″ | ~75 lb (34 kg) |
Frequently asked questions
How much does a 4×8 sheet of 3/4 plywood weigh?
A 4×8 (48″×96″) sheet of 3/4″ generic plywood weighs approximately 60 lb (27 kg) at a density of 700 kg/m³. Birch and oak plywoods are heavier; pine and softwood plywoods are lighter.
How is plywood weight calculated?
Multiply the sheet volume (length × width × thickness) by the wood's density. The calculator above does this automatically.
What is the weight of MDF compared to plywood?
MDF is about 8–10% heavier than generic plywood. A 4×8 sheet of 3/4″ MDF weighs approximately 65 lb (29 kg), versus about 60 lb (27 kg) for the same sheet in plywood.
