Drywall Mud Tape Calc

Struggling to figure out how many buckets of mud, rolls of tape, and boxes of screws you need for a drywall job? Stop guessing and over-ordering. This app calculates exact quantities for joint compound, paper tape, corner bead, drywall sheets, and screws based on your room dimensions or manual joint lengths.

TWO CALCULATION MODES:

Room Mode — Enter room length, width, and height. The app automatically calculates wall area, joint layouts, and all material quantities. Perfect for standard rectangular rooms.

Manual Entry Mode — Enter total joint length and sheet count directly. Ideal for irregular spaces, partial walls, cathedral ceilings, or multi-room projects where you already know joint measurements.

COMPLETE MATERIAL OUTPUT:
- Drywall sheets (4x8 ft or 1.2x2.4 m)
- Joint tape (paper tape in feet or meters)
- Joint compound / mud (gallons, buckets, or liters)
- Corner bead lengths
- Drywall screws

SAE & METRIC UNITS:
Switch between feet/inches and meters with one tap. All outputs convert automatically.
