About this calculator
Standard drywall sizes: 4×8 ft (32 ft²) is the most common — fits stairwells, easier to handle. 4×12 ft (48 ft²) for large continuous walls — fewer seams. Half-inch thickness is standard for walls; 5/8" for ceilings and fire-rated areas.
Frequently asked
4×8 easier for one person; 4×12 means fewer seams (less mudding). Pros use 12-footers; DIYers usually 8-footers.
