What happens in this clip
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.
Goal: Measure the total width of your stair tread and then calculate the desired carpet tread width by subtracting the amount of exposed wood you want on each side.

Pro tips for this step
- Oak Valley Designs Pro Tip: Older staircases often vary step to step. Number and photograph each one that differs, and measure twice before you write it down — it saves a costly re-order.

What's said in this clip
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.

Step 4 of 5: The Details Matter: Record, Label, and Double-Check for a Custom Fit
As you complete the width and depth measurements for each step, it's time to meticulously record these dimensions (width × depth) in your notebook. This step is crucial for achieving that perfect, custom-made to fit result! If you discover that some steps have slightly different dimensions – which is quite common, especially in charming older homes – be sure to number each unique step clearly. For custom carpet stair treads, taking a photograph of each individual step, particularly those with varying measurements, is highly recommended to ensure absolute accuracy. To guarantee peace of mind and avoid any frustration, always double-check all your measurements before recording them. As we always say, 'Measure twice; write it down once!'
