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.

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".
