Room drywall takeoff
Estimate sheets plus rough finishing-material quantities from a room's wall and ceiling area.
Sheet count is a takeoff estimate. Layout, orientation, fire-rated assemblies, moisture areas and local requirements can change the board type and final quantity.
Finishing materials
Tape, screws and compound are rule-of-thumb planning quantities. Finish level, framing and product choice can change usage.
Openings are optional
Large openings can be deducted, but small cutouts often create scrap anyway. Keep an appropriate waste allowance.
