Start by measuring the entire width of your stair tread. This measurement typically goes from a spindle to the wall, or simply wall-to-wall if there are no spindles. For example, if the full width is 43 inches. Next, decide how much exposed wood you want to see on either side of the carpet stair tread. The recommendation is 2 to 4 inches per side. If you choose 4 inches per side, that's a total of 8 inches (4 inches + 4 inches). Subtract this total from the full stair width (e.g., 43 - 8 = 35 inches). This final number is the ideal width for your carpet stair tread.

You're going to take a measurement from the spindle to the wall. It could be wall to wall, whatever your staircase looks like. and that is 43 in. Next, you're going to want to decide how much wood to see on either side of the carpet stair tread. So, we recommend 2 to 4 in of wood on either side. Let's go with 4 in for this order. And let's say 4 in + 4 in is 8. 43 - 8 is 35. So, a 35 wide stair tread is perfect for this step. Let's go to measurement number two.
