Before you open a calculator
Read the decisions behind the estimate
Follow the sheet-count, sheet-size, and finishing-scope guides before buying drywall for a room.
- Step 1
Measure wall and ceiling surfaces separately, subtract meaningful openings, and record whether the ceiling is included.
- Step 2
Choose sheet dimensions for the space and access constraints; the shortest sheet is not always the least wasteful.
- Step 3
Estimate finishing materials and job scope separately from sheet quantity, then verify waste and finishing levels.
