Measure Stair Tread Depth

What happens here

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.
