Drywall Calculator

Calculate how many drywall sheets you need for any room. Enter wall length, height, and openings to get an accurate sheet count with waste allowance.

This calculator provides a preliminary sheet-count estimate, not construction, fire-safety, moisture-control, or code advice. Verify dimensions with a wall-by-wall layout and use approved products and assemblies. Follow manufacturer instructions, permits, local requirements, safe lifting practices, and dust-control guidance. Consult a qualified contractor or design professional for rated separations, wet areas, damaged or mold-affected construction, complex framing, or uncertain requirements.
