All Calculators/Drywall Calculator

Drywall Calculator

Calculate sheets, joint compound, tape, and screws for a full room.

The drywall calculator estimates sheet count, joint compound buckets, tape rolls, and screws for any room. It deducts door and window areas from the wall square footage and optionally includes the ceiling. Use it to build your material list before pulling the trigger on a delivery.
  • Order 10% over your sheet count — damaged corners and miscuts happen on every job.
  • Hang sheets horizontally to reduce the number of butt joints, which are harder to finish than tapered joints.
  • Keep joint compound in a temperature-controlled space; freezing ruins the mix and wastes material.
