The Drywall Needed for a Room calculator computes the number of drywall sheets required to cover a walls and ceiling of a rectangular room based on the length and height of the walls.
Dimensions of a Room
INSTRUCTIONS: Choose units and enter the following:
- (L) Length of Room
- (W) Width of Room
- (H) Height of Ceiling
- (SS) Size of the drywall sheets (4x8 or 4x12)
Number of Drywall Sheets (nS): The calculator returns the number of drywall sheets and square feet of area for the room including the ceiling and for the walls only.
The Math / Science
This calculator computes the area of the room and then divides the area by either:
- 32 square feet for a 4x8
- 48 square feet for a 4x12
The number of drywall sheets is ROUNDED UP.
Walls are often drywalled with a thicker material than ceilings because the come into more contact with things and people. That's why it's not uncommon for walls to be 5/8" thick drywall and ceilings to be 1/2".
