Always buy 5-10% extra for cuts, waste, and mistakes. It's better to return unopened sheets than to run out mid-project.
Drywall Calculator estimates sheet count, screws, tape, joint compound, waste-adjusted material needs, and estimated cost from room dimensions, wall and ceiling area, sheet size, waste percentage, and material prices. It is free to use, works in a browser, and is designed for contractors, remodelers, builders, and DIY homeowners. Use this calculator when you need a fast material estimate before ordering supplies, comparing costs, or planning a construction project.

For walls, 1/2 inch is standard. For ceilings, 1/2 or 5/8 inch (5/8 inch is better for sag resistance). For bathrooms, use moisture-resistant (green board).
Calculate drywall sheets by dividing total area by 32 (4x8 sheet) or 48 (4x12 sheet). Add 5-10% for waste.
Measure length, width, and height of the room. Calculate ceiling and wall areas separately.
Decide between 4x8 or 4x12 sheets. Larger sheets mean fewer seams but are heavier.
Divide total area by sheet area (32 or 48 sq ft). Round up to whole sheets.
Plan for about 1 screw per square foot, or roughly 1.5-2 lbs of screws per sheet.
One 5-gallon bucket of joint compound covers about 12-15 sheets.
