Our stair rise and run calculator determines the details of your stairs for various combinations of known and unknown values. For example, we can assume that you know the rise and run of one step, and you want to calculate the remaining characteristics. How would you proceed?

A: Rise. The distance from the floor to the top of the staircase. In this illustration, the total rise is 45 and 7/8 inches. B: Top Step. The top step can be slightly shorter than the other steps if the rise can't be divided evenly. It should be no more than 3/8 inches shorter than the bottom step. C: Total Run.

The tread size (min 10ins / 25.4cm) is dictated by the average adult foot size, although it is not necessary to be able to fit your entire foot on a tread in order for walking up the stairs to be both comfortable and safe. The riser height (max 7¾ins / 19.7cm) is limited by the way in which we come down the stairs.

Ideal Stair Rule of Thumb. Perfect stair (for most users): Rise = 7", Run = 11". The sum of one stair or step tread or "run" and one step height or "riser" should always be about 17" or 18" in total. As the step rise gets shorter. the step run must get longer.

The standard size for a staircase in a residential home is typically between 9 and 12 feet long; although, this can vary depending on the height of your ceiling. To accurately calculate the length of your staircase, measure the distance between the floor on your first level and the floor of your second level carefully.
Standard Dimensions For Stairs
To determine their length, square the run, square the individual stair rise, and then add the 2 numbers together. From there, find the square root of the answer for the length of each stringer. For instance, if the run is 10 inches, square 10 by multiplying it by itself to get 100.

For standard spiral staircase dimensions, it should be from 3 feet 6 inches in diameter and a walking path of 17 inches to 6 feet in diameter with a 32-inch walking path. The guidelines for spiral stair installations tend to be different from regular staircases because these can be trickier to navigate. Vertical Rise and Headroom Vertical Rise

→ stair will be comfortable 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.
