The **Cost to Drywall a Room's Walls** calculator computes an estimated cost of drywall to cover the interior walls and ceiling of a rectangular room defined by length, width and height. The user can choose the size (4x8 or 4x12) of the wall board (gypsum) and provide a unit price for those wall boards.* Drywall in a room*
