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.
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.
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.

To begin, position your straightedge or tape measure flat against the top of your bullnose tread. Carefully extend your measurement from the vertical face of the back riser, *over* the rounded front edge, all the way to the absolute front lip of the tread. This isn't just about the flat surface; it’s about capturing the *entire* projection of your step. This precise measurement is key for a custom-made fit that truly elevates your staircase.
