Next, measure upward across the tread and riser of 1 stair. After measuring the riser, get the length and width of any landings, then round all of your measurements up to the nearest foot. Once you have these numbers, multiply the tread and riser measurements together to get the square footage of 1 step, then multiply your result by the number of steps. Likewise, multiply the length and width of the landing to get its area. Finally, add the area of the landing with the area of all the steps to find out how much carpet you need.
