Below is a handy calculator to determine staircase tread depth/riser height.

You can key in inputs including top and bottom level, riser height (typically 150 or 175mm high).

The calculator also helps you determine the overall flight dimensions if you key in the tread depth as well. Very useful for staircase design.
