Room Drywall Material And Cost Calculator

This calculator requires the use of Javascript enabled and capable browsers. This drywall calculator will calculate the amount the amount of sheetrock needed to drywall an area or a room. The term sheetrock refers to gypsum board. It comes in various sizes, thicknesses and qualities. The terms green or wet rock refers to a special variety used in bathrooms and indoor spas. As a general rule, 4x8 sizes are used in most residential applications, while 4x9, 4x10 and 4x12 are usually used in commercial applications. They are also much more difficult to handle, especially for one person. Before you begin, take the room measurements for the data entry. If you have sloping walls, follow the special case instructions on how to determine this square footage. For wall height, measure from floor to ceiling. For wall perimeter of the areas you plan to drywall, measure the length of each wall. Add all length figures together to obtain the total horizontal distance, or perimeter of the wall structure. If you are drywalling the ceiling, measure the width and length, usually easiest to do by measure the floor under it. You may omit this if you do not plan to drywall the ceiling. Accumulate the measurements of all excluded sections by measuring the height and width of each area separately and adding all widths into one total and all heights into a second total. Sloping walls form a triangular wall space. To calculate a triangle’s square footage, multiply the length of the wall at the base of the triangle by its height and divide by 2, or just use our CSG Area Calculator; other possible applicable triangle calculations are available here. If you wish to get an approximate cost of the sheetrock, enter the cost of one drywall sheet of the size you plan to use; you may leave this a zero if you are not interested in the price. Enter all of the other values in the appropriate areas. Click the Calculate button for all fields to be calculated; at least ONE value for drywall is required. To do another, click the Clear Values button and then enter a new set of values. You may also wish to just change certain fields and recalculate.
