What happens in this clip
Measure the full depth of your stair tread, from the back of the tread to the front edge (bullnose). For instance, if the measurement is 11 and 1/4 inches. It is crucial not to order this exact depth. Instead, subtract a small amount, typically 1/4 inch to 1/2 inch, from the total depth. This slight reduction ensures that the carpet stair tread sits tightly against the bullnose without hanging over, which is important for both aesthetics and safety. For example, subtracting 1/4 inch from 11 and 1/4 inches results in an 11-inch depth for your carpet tread.
Goal: Measure the full depth of the stair tread and then subtract a small amount (1/4 to 1/2 inch) to ensure a snug fit that prevents the carpet from overhanging the bullnose.

About the full video
This video provides detailed instructions on how to accurately measure stair treads for custom carpet installations. It covers measuring both the width and depth of each tread, offering guidance on how to adjust these measurements to achieve the desired aesthetic of exposed wood. A helpful tip for visualizing the final fit using painter's tape is also included to ensure satisfaction before ordering.
What's said in this clip
That's going to be your depth. Your depth is going to be all right. This measures 11 and 1/4. Okay, we're not going to order 11 and 1/4. We're going to subtract a/4 in and we're going to order an 11. So that'll give us a little space in the back, which is perfect. And what you want so that the carpet stair tread is really tight on this front bullnness. You do not want that to hang over. And that's really important. You could also say, well, I can either subtract a/4 in or a/ in would also be fine. It doesn't have to be an absolute perfect science. You just want a little space in the back. So, anywhere from a/4 in to a/ inch is perfect. And that's it. So, I would do a 35 by 11 and that would be great.

Step 3 of 4: Getting the Width Right: From Wall-to-Wall or Edge-to-Edge
Now, let's tackle the width! For each tread, carefully run your tape measure across the front edge. This is key: always ensure your tape is perfectly parallel to the back edge of the tread where it meets the riser. If your beautiful stairs are nestled between two walls, measure straight from wall to wall. If one side of your staircase is open, measure precisely from the outer edge of the tread to the inner edge. For that polished, custom-fit aesthetic – the kind that truly elevates your staircase – a common practice for residential treads is to leave about a 1-inch space on each side. So, for example, a 36-inch wide stair would beautifully accommodate a 34-inch wide tread, giving you that clean, bordered look that says 'quality and care.'
