The riser count is the total rise divided by the desired riser, rounded to the nearest count. The run multiplies the treads by the tread depth. The stringer is the hypotenuse. A 7.75 in rise and a 10 in tread are the example limits on this page.
Why this exists
A rise of 108 with a riser of 7.5 and a tread of 11 makes 14 risers and 13 treads. The rise becomes 7.71, the run is 143, and the stringer is 14.93.
The riser count is the total rise divided by the desired riser, rounded to the nearest count. The run multiplies the treads by the tread depth. The stringer is the hypotenuse. A 7.75 in rise and a 10 in tread are the example limits on this page.

How this page works it out
A rise of 108 with a riser of 7.5 and a tread of 11 makes 14 risers and 13 treads. The rise becomes 7.71, the run is 143, and the stringer is 14.93. The limit numbers are the example on this page, not a permit rule for every country.
The riser count divides the total rise by the desired riser and rounds to the nearest count. The run multiplies the treads by the tread depth, and the stringer is that right triangle’s hypotenuse.
Inches are the English sample and centimeters are the other samples. A 7.75 in rise and a 10 in tread are the example limits on this page, not a permit. The numbers stay in this browser.
