What riser height is recommended for comfortable stairs?

A riser height between 6 to 7 inches (15 to 18 cm) is recommended for comfortable residential walking stairs.

How is the staircase pitch angle calculated?

The stair angle is calculated using the inverse tangent of the riser height divided by the tread depth (Pitch = arctan(Riser/Tread) * 180 / pi).
