Stair Riser Height
The stair riser height calculated from the stair's total rise and number of risers needed.
- enter the total rise ( feet, inches and fraction of an inch)
- number of risers you wish to calculate for (option one)
- number of risers you wish to calculate for (option two )
- precision (preset @ 16 but can be changed)
- total rise converted into decimal feet
- total rise converted into inches
- the height of one riser (result of option one)
- the height of one riser (result of option two)
Note: The actual fraction result is most of the time not very useful. Precision is used for the fraction. To keep it usable it is preset at 16, meaning that the denominator of the fraction will be no larger than a 16th to have a usable fraction in the result. By forcing the fraction to a usable denominator, there can be a small error in the result and when you multiply the result by the number of risers needed, the result can be slightly off. One should always recalculate the riser result by the amount of risers and compare it to the "total rise in inches" result. This slight difference in result, when you know about it beforehand, can easily be made up by adjusting the riser heights accordingly.

- the height of one riser
- number of risers
- total rise in inches keeping the same denominator as entered in "the height of one riser"
