Drywall Sheets, Mud & Tape Calculator

Enter room sizes and choices. The optimizer picks sheet sizes & orientation to minimize seams and waste, then visualizes seams and outputs tape, mud, and materials.


Add doors/windows to deduct wall area. (Simple deduction; seam layout ignores openings.)
Ceiling sheets are drawn perpendicular to joists.

Optimizer will choose orientation (vertical/horizontal) & size mix to reduce seams and waste per wall & ceiling.
Level 5 adds skim coat (area-based). Values are editable.
