What is the Drywall Weight Calculator?
The Drywall Weight Calculator helps you estimate the total weight of drywall (gypsum board) based on the square footage and thickness. This is essential for construction planning, load calculations, and material handling.
How to Use the Drywall Weight Calculator
- Enter Total Square Footage: Input the total area to be covered in square feet
- Enter Drywall Thickness: Specify the thickness of the drywall in inches (common sizes: 0.25", 0.375", 0.5", 0.625")
- View Results: The calculator displays the estimated weight in pounds
Drywall Weight Formula
The formula for calculating drywall weight is:
$$\text{Weight (lbs)} = \frac{\text{Area (ft}^2\text{)} \times \text{Thickness (in)}}{12} \times 38.205$$
Where:
- Area = Total square footage of drywall
- Thickness = Thickness of the drywall sheet in inches
- 38.205 = Density constant for standard gypsum drywall (lbs/ft³)
Calculation Example
For 50 ft² of drywall with 0.5 inch thickness:
$$\text{Weight} = \frac{50 \times 0.5}{12} \times 38.205 = \frac{25}{12} \times 38.205 \approx 79.59 \text{ lbs}$$
Common Drywall Thicknesses
- 1/4" (0.25"): Lightweight, used for curved surfaces
- 3/8" (0.375"): Common for covering existing walls
- 1/2" (0.5"): Standard for walls and ceilings
- 5/8" (0.625"): Fire-rated, heavy-duty applications
Weight per 4 x 8 Sheet (Standard Sizes)
- 1/4" sheet: ~38 lbs
- 3/8" sheet: ~57 lbs
- 1/2" sheet: ~76 lbs
- 5/8" sheet: ~95 lbs
Applications
- Load Calculations: Structural planning and support requirements
- Material Handling: Determining labor and equipment needs
- Transportation: Planning for delivery and logistics
- Safety Planning: Ensuring proper lifting techniques and crew size
