What is the typical stair riser height?

For each rise: minimum 130mm, maximum 225mm. For each going: minimum 215mm, maximum 355mm. The going shall be not greater than the tread depth (TD) plus a maximum gap of 30 mm between the rear edge of one tread and the nosing of the tread above.

What is the minimum stair riser height?

4 inches
Stair riser heights shall be 7 inches (178 mm) maximum and 4 inches (102 mm) minimum. The riser height shall be measured vertically between the leading edges of adjacent treads.

What is the most comfortable stair height?

Rule one says that rise plus run (r+R) should equal 18 inches. Why? That’s what most people find to be a comfortable stride on most stairs. You can cheat a bit up or down, but below 17” and more than 19” will result in steps that require strides either too big or too small for most people.

Are stairs at 45 degrees?

For example, if you were crazy and built a staircase with a 12 inch tread and riser, then the angle of the stringer to the floor would be 45 degrees. A more common angle is about 37 degrees.
