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.

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 2 of 3: Precision Measuring Your Straight Stair Sections for a Flawless Fit

With your tape measure in hand, let's turn our attention to the straight sections of your staircase. For each and every tread in both flights, you'll want to meticulously capture its exact width and depth. Here's a crucial tip for a truly professional-looking result: always measure from the *outer edge of the tread to the outer edge of the tread*. Avoid measuring from wall to wall, especially near turns, as those walls are rarely perfectly square, and we want your custom treads to lay perfectly flat and secure. As you measure, give each tread a sequential number – this simple step will keep your project organized and make ordering a breeze. Don't forget to account for any existing trim or the stair nose overhang; these details ensure your carpet treads sit beautifully and protect your wood. For ultimate accuracy, a carpenter's square can be your best friend for those right-angled measurements, giving you peace of mind that your DIY stair remodel will be a stunning success.

how to measure an L-shaped staircase for carpet stair treads

An L-shaped staircase, often called a quarter-turn, brings unique architectural charm to your home. But when it comes to adding the safety and style of carpet stair treads, its 90-degree turn can seem a little tricky to measure. Don't worry, we're here to empower your DIY journey! The secret to a perfect, custom fit for your Oak Valley Designs treads is to see your L-shaped staircase as three distinct areas: the first straight flight, the turning section, and the second straight flight. The way you approach the turn—whether it's a spacious landing or elegant winder steps—will guide your measuring strategy. For straight sections, you'll precisely measure each tread's width and depth. For a landing, it's one simple, larger measurement. For winder steps, each unique, tapered step gets its own careful attention. And here’s a pro tip for peace of mind: always measure from the *tread edge to tread edge*, never wall to wall. This ensures your custom treads fit beautifully, even if your walls aren't perfectly square, delivering the safety and elegance your family deserves.
