Figuring out how much carpeting you'll need for a room seems pretty straightforward — length times width equals area, and off you go to place your order. It can be a little more complicated than that, though, so use this calculator to help you figure out how much carpeting you'll actually have to buy to cover your floor.

Enter the overall dimensions of the area to be carpeted. Ignore anything that butts into the room, like a fireplace or a closet — enter the total outside length and width.
