HOW IT IS CALCULATED
Estimate stair risers and horizontal run
Estimate a practical riser count from total rise, then calculate actual riser height and approximate run.

01Values
02risers ≈ total rise ÷ desired riser
03Result
The riser count is rounded to a whole number before actual height is recalculated.
Small changes in riser count change every step
Once the count changes, actual riser height is redistributed across the entire staircase.

In short
What logic does the calculator use?
risers ≈ total rise ÷ desired riser
Example?
The riser count is rounded to a whole number before actual height is recalculated.
