Drywall Planner helps homeowners, DIYers and contractors plan drywall jobs. Enter your room size and wall height, and it calculates the number of sheets for 4x8, 4x9, 4x10 and 4x12 boards, with a wall-by-wall sheet layout. It also estimates joint compound, tape and screws. Free, no sign-up.
Most drywall calculators just divide wall area by sheet size and leave you guessing on waste. I wanted a tool that lays out the sheets wall by wall and gives material estimates, so DIYers buy the right amount the first time.
