How to Measure Stairs Calculator

Number of treads, number of risers, length of stringer, and the base length – these are the necessary values while measuring the stairs.

Get your calculations by simply entering the stair height (total rise) and tread size.

To fill in the “Stair height” value, measure the vertical height from the bottom of the first step and the top of the finished landing. This is the total height the stairs will span.

Then enter your desired tread size (the horizontal surface of the step). The standard tread size of 240 mm has been pre-set as the default setting.
