Max. rise is now 7-3/4, and minimum run is 10, nose-to-nose, with at least a 3/4 bullnose required, so the step is actually about 11 long. For commercial or multi-family stairs, it is still 7 max and 11 min.ax. rise is now 7-3/4, and minimum run is 10, nose-to-nose, with at least a 3/4 bullnose required, so the step is actually about 11 long.

Multiply this by the number of stairs youâll be covering to determine how long of a carpet runner youâll need. For example, if the rise of your stairs is the standard 7 Â½ inches and the tread is 8 inches, the stair measure is 15 Â½ inches.. Determine the stair measure to calculate how long of a carpet runner youâll need. You can do this by measuring the rise and the tread to the nearest whole number and then adding these two numbers together. Round this up to an even number if applicable, and then add 2 inches to give yourself a buffer.
